encodeAbiParameters

encodeAbiParameters<TParams>(params, values): EncodeAbiParametersReturnType

Type parameters

• TParams extends readonly unknown[] | readonly AbiParameter[]

Parameters

• params: TParams

a set of ABI Parameters (params), that can be in the shape of the inputs or outputs attribute of an ABI Item.

• values: TParams extends readonly AbiParameter[] ? { [K in string | number | symbol]: { [K in string | number | symbol]: AbiParameterToPrimitiveType<TParams<TParams>[K<K>], AbiParameterKind> }[K] } : never

a set of values (values) that correspond to the given params.

Returns

EncodeAbiParametersReturnType

Description

Encodes a list of primitive values into an ABI-encoded hex value.

• Docs: https://viem.sh/docs/abi/encodeAbiParameters#encodeabiparameters

  Generates ABI encoded data using the ABI specification, given a set of ABI parameters (inputs/outputs) and their corresponding values.

Examples

import { encodeAbiParameters } from 'viem'

const encodedData = encodeAbiParameters(
  [
    { name: 'x', type: 'string' },
    { name: 'y', type: 'uint' },
    { name: 'z', type: 'bool' }
  ],
  ['wagmi', 420n, true]
)

You can also pass in Human Readable parameters with the parseAbiParameters utility.

import { encodeAbiParameters, parseAbiParameters } from 'viem'

const encodedData = encodeAbiParameters(
  parseAbiParameters('string x, uint y, bool z'),
  ['wagmi', 420n, true]
)
