EncodedData

Branded hex string representing ABI-encoded data. Used for function calls, constructor arguments, and custom error data.

​
Type

type EncodedDataType = `0x${string}` & { readonly [brand]: "EncodedData" };

​
Construction

import * as EncodedData from '@tevm/voltaire/primitives/EncodedData';

// From hex string
const data = EncodedData.from("0x00000001");

// From bytes
const bytes = new Uint8Array([0, 0, 0, 1]);
const data = EncodedData.fromBytes(bytes);

​
Methods

  • from(value) - Universal constructor (hex or bytes)
  • fromBytes(bytes) - From Uint8Array
  • toBytes(data) - Convert to Uint8Array
  • equals(a, b) - Compare equality (case-insensitive)

​
Example

import * as EncodedData from '@tevm/voltaire/primitives/EncodedData';

// Function call data
const calldata = EncodedData.from("0xa9059cbb000000000000000000000000...");

// Convert to bytes for execution
const bytes = EncodedData.toBytes(calldata);

// Compare encoded data
const equal = EncodedData.equals(data1, data2);
