The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

TypeScript enum or const enum.\n *\n * One of the goals of this library is to enable people to use some or none of it without having to\n * bundle all of it.\n *\n * If we made the set of error codes an enum then anyone who imported it (even if to only use a\n * single error code) would be forced to bundle every code and its label.\n *\n * Const enums appear to solve this problem by letting the compiler inline only the codes that are\n * actually used. Unfortunately exporting ambient (const) enums from a library like `@solana/errors`\n * is not safe, for a variety of reasons covered here: https://stackoverflow.com/a/28818850\n */\nexport type

This allows for both synchronous\n * and asynchronous transformations and extensions of the client.\n *\n * Plugins are usually applied using the `use` method on a {@link Client} or {@link AsyncClient}\n * instance, which {@link createEmptyClient} provides as a starting point.\n *\n * @typeParam TInput - The input client object type that this plugin accepts.\n * @typeParam TOutput - The output type.

The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

TypeScript enum or const enum.\n *\n * One of the goals of this library is to enable people to use some or none of it without having to\n * bundle all of it.\n *\n * If we made the set of error codes an enum then anyone who imported it (even if to only use a\n * single error code) would be forced to bundle every code and its label.\n *\n * Const enums appear to solve this problem by letting the compiler inline only the codes that are\n * actually used. Unfortunately exporting ambient (const) enums from a library like `@solana/errors`\n * is not safe, for a variety of reasons covered here: https://stackoverflow.com/a/28818850\n */\nexport type

This allows for both synchronous\n * and asynchronous transformations and extensions of the client.\n *\n * Plugins are usually applied using the `use` method on a {@link Client} or {@link AsyncClient}\n * instance, which {@link createEmptyClient} provides as a starting point.\n *\n * @typeParam TInput - The input client object type that this plugin accepts.\n * @typeParam TOutput - The output type.

The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

TypeScript enum or const enum.\n *\n * One of the goals of this library is to enable people to use some or none of it without having to\n * bundle all of it.\n *\n * If we made the set of error codes an enum then anyone who imported it (even if to only use a\n * single error code) would be forced to bundle every code and its label.\n *\n * Const enums appear to solve this problem by letting the compiler inline only the codes that are\n * actually used. Unfortunately exporting ambient (const) enums from a library like `@solana/errors`\n * is not safe, for a variety of reasons covered here: https://stackoverflow.com/a/28818850\n */\nexport type

This allows for both synchronous\n * and asynchronous transformations and extensions of the client.\n *\n * Plugins are usually applied using the `use` method on a {@link Client} or {@link AsyncClient}\n * instance, which {@link createEmptyClient} provides as a starting point.\n *\n * @typeParam TInput - The input client object type that this plugin accepts.\n * @typeParam TOutput - The output type.

`cancelled`: The Transaction has been cancelled (e.g. `value === 0n`)\n * - `replaced`: The Transaction has been replaced (e.g. different `value` or `data`)\n *\n * @param args - {@link WaitForTransactionReceiptParameters}\n * @returns The transaction receipt. {@link WaitForTransactionReceiptReturnType}\n *\n * @example\n * import { createPublicClient, http } from 'viem'\n * import { mainnet } from 'viem/chains'\n *\n * const client = createPublicClient({\n * chain: mainnet,\n * transport: http(),\n * })\n * const transactionReceipt = await client.waitForTransactionReceipt({\n * hash: '0x4ca7ee652d57678f26e887c149ab0735f41de37bcad58c9f6d3ed5824f15b74d',\n * })\n */\n waitForTransactionReceipt: (\n args: WaitForTransactionReceiptParameters,\n ) => Promise>\n /**\n * Watches and returns incoming block numbers.\n *\n * -

The formula is: y² = x³ + ax + b.\n *\n * ### Parameters\n *\n * To initialize a weierstrass curve, one needs to pass following params:\n *\n * * a: formula param\n * * b: formula param\n * * Fp: finite field of prime characteristic P; may be complex (Fp2). Arithmetics is done in field\n * * n: order of prime subgroup a.k.a total amount of valid curve points\n * * Gx: Base point (x, y) aka generator point. Gx = x coordinate\n * * Gy: ...y coordinate\n * * h: cofactor, usually 1. h*n = curve group order (n is only subgroup order)\n * * lowS: whether to enable (default) or disable \"low-s\" non-malleable signatures\n *\n * ### Design rationale for types\n *\n * * Interaction between classes from different curves should fail:\n * `k256.Point.BASE.add(p256.Point.BASE)`\n * * For this purpose we want to use `instanceof` operator, which is fast and works during runtime\n * * Different calls of `curve()` would return different classes -\n * `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,\n * it won't affect others\n *\n * TypeScript can't infer types for classes created inside a function. Classes is one instance\n * of nominative types in TypeScript and interfaces only check for shape, so it's hard to create\n * unique type for every function call.\n *\n * We can use generic types via some param, like curve opts, but that would:\n * 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)\n * which is hard to debug.\n * 2. Params can be generic and we can't enforce them to be constant value:\n * if somebody creates curve from non-constant params,\n * it would be allowed to interact with other curves with non-constant params\n *\n * @todo https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#unique-symbol\n * @module\n */\n/*! noble-curves - MIT License (c) 2022 Paul Miller (paulmillr.com) */\n// prettier-ignore\nimport {\n pippenger, validateBasic, wNAF,\n type AffinePoint, type BasicCurve, type Group, type GroupConstructor\n} from './curve.ts';\n// prettier-ignore\nimport {\n Field,\n FpInvertBatch,\n getMinHashLength, invert, mapHashToField, mod, validateField,\n type IField\n} from './modular.ts';\n// prettier-ignore\nimport {\n aInRange, abool,\n bitMask,\n bytesToHex, bytesToNumberBE, concatBytes, createHmacDrbg, ensureBytes, hexToBytes,\n inRange, isBytes, memoized, numberToBytesBE, numberToHexUnpadded, validateObject,\n type CHash, type Hex, type PrivKey\n} from './utils.ts';\n\nexport type { AffinePoint };\ntype HmacFnSync = (key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array;\n/**\n * When Weierstrass curve has `a=0`, it becomes Koblitz curve.\n * Koblitz curves allow using **efficiently-computable GLV endomorphism ψ**.\n * Endomorphism uses 2x less RAM, speeds up precomputation by 2x and ECDH / key recovery by 20%.\n * For precomputed wNAF it trades off 1/2 init time & 1/3 ram for 20% perf hit.\n *\n * Endomorphism consists of beta, lambda and splitScalar:\n *\n * 1.

TypeScript enum or const enum.\n *\n * One of the goals of this library is to enable people to use some or none of it without having to\n * bundle all of it.\n *\n * If we made the set of error codes an enum then anyone who imported it (even if to only use a\n * single error code) would be forced to bundle every code and its label.\n *\n * Const enums appear to solve this problem by letting the compiler inline only the codes that are\n * actually used. Unfortunately exporting ambient (const) enums from a library like `@solana/errors`\n * is not safe, for a variety of reasons covered here: https://stackoverflow.com/a/28818850\n */\nexport type

This allows for both synchronous\n * and asynchronous transformations and extensions of the client.\n *\n * Plugins are usually applied using the `use` method on a {@link Client} or {@link AsyncClient}\n * instance, which {@link createEmptyClient} provides as a starting point.\n *\n * @typeParam TInput - The input client object type that this plugin accepts.\n * @typeParam TOutput - The output type.

`cancelled`: The Transaction has been cancelled (e.g. `value === 0n`)\n * - `replaced`: The Transaction has been replaced (e.g. different `value` or `data`)\n *\n * @param args - {@link WaitForTransactionReceiptParameters}\n * @returns The transaction receipt. {@link WaitForTransactionReceiptReturnType}\n *\n * @example\n * import { createPublicClient, http } from 'viem'\n * import { mainnet } from 'viem/chains'\n *\n * const client = createPublicClient({\n * chain: mainnet,\n * transport: http(),\n * })\n * const transactionReceipt = await client.waitForTransactionReceipt({\n * hash: '0x4ca7ee652d57678f26e887c149ab0735f41de37bcad58c9f6d3ed5824f15b74d',\n * })\n */\n waitForTransactionReceipt: (\n args: WaitForTransactionReceiptParameters,\n ) => Promise>\n /**\n * Watches and returns incoming block numbers.\n *\n * -
