Type Aliases

InitCodeType

InitCodeType = Uint8Array & object

Defined in: src/primitives/InitCode/InitCodeType.ts:8 Branded InitCode type Contract creation bytecode (constructor + runtime code) Deployed during contract creation transaction

Type Declaration

[brand]

readonly [brand]: "InitCode"

Functions

_equals()

_equals(a, b): boolean

Defined in: src/primitives/InitCode/equals.js:15 Check if two InitCode instances are equal

Parameters

a

InitCodeType First InitCode

b

InitCodeType Second InitCode

Returns

boolean true if equal

Example

import * as InitCode from './primitives/InitCode/index.js';
const code1 = InitCode.from("0x6001");
const code2 = InitCode.from("0x6001");
InitCode._equals(code1, code2); // true

_estimateGas()

_estimateGas(code): bigint

Defined in: src/primitives/InitCode/estimateGas.js:16 Estimate gas cost for contract creation Gas cost = 21000 (base) + 200 * non-zero bytes + 4 * zero bytes + 32000 (creation)

Parameters

code

InitCodeType InitCode

Returns

bigint Estimated gas cost

Example

import * as InitCode from './primitives/InitCode/index.js';
const init = InitCode.from("0x608060405234801561001057600080fd5b50...");
const gas = InitCode._estimateGas(init);
console.log(`Estimated gas: ${gas}`);

_extractRuntime()

_extractRuntime(code, offset): RuntimeCodeType

Defined in: src/primitives/InitCode/extractRuntime.js:18 Extract runtime code from init code at specified offset Init code contains constructor logic followed by runtime code. This extracts the runtime portion starting at the given offset.

Parameters

code

InitCodeType InitCode

offset

number Byte offset where runtime code starts

Returns

RuntimeCodeType RuntimeCode

Example

import * as InitCode from './primitives/InitCode/index.js';
const init = InitCode.from("0x608060405234801561001057600080fd5b50...");
// Assume constructor is 100 bytes
const runtime = InitCode._extractRuntime(init, 100);

_toHex()

_toHex(data): HexType

Defined in: src/primitives/InitCode/toHex.js:15 Convert InitCode to hex string

Parameters

data

InitCodeType InitCode

Returns

HexType Hex string

Example

import * as InitCode from './primitives/InitCode/index.js';
const code = InitCode.from("0x608060405234801561001057600080fd5b50...");
const hex = InitCode._toHex(code);

equals()

equals(a, b): boolean

Defined in: src/primitives/InitCode/index.ts:18

Parameters

a

string | Uint8Array<ArrayBufferLike> | InitCodeType

b

string | Uint8Array<ArrayBufferLike> | InitCodeType

Returns

boolean

estimateGas()

estimateGas(value): bigint

Defined in: src/primitives/InitCode/index.ts:38

Parameters

value

string | Uint8Array<ArrayBufferLike> | InitCodeType

Returns

bigint

extractRuntime()

extractRuntime(value, offset): RuntimeCodeType

Defined in: src/primitives/InitCode/index.ts:31

Parameters

value

string | Uint8Array<ArrayBufferLike> | InitCodeType

offset

number

Returns

RuntimeCodeType

from()

from(value): InitCodeType

Defined in: src/primitives/InitCode/from.js:18 Create InitCode from various input types

Parameters

value

Hex string or Uint8Array string | Uint8Array<ArrayBufferLike>

Returns

InitCodeType InitCode

See

https://voltaire.tevm.sh/primitives/init-code for InitCode documentation

Since

0.0.0

Throws

Example

import * as InitCode from './primitives/InitCode/index.js';
const code1 = InitCode.from("0x608060405234801561001057600080fd5b50...");
const code2 = InitCode.from(new Uint8Array([0x60, 0x80, 0x60, 0x40, ...]));

fromHex()

fromHex(hex): InitCodeType

Defined in: src/primitives/InitCode/fromHex.js:15 Create InitCode from hex string

Parameters

hex

string Hex string

Returns

InitCodeType InitCode

Throws

If hex string is invalid

Example

import * as InitCode from './primitives/InitCode/index.js';
const code = InitCode.fromHex("0x608060405234801561001057600080fd5b50...");

toHex()

toHex(value): HexType

Defined in: src/primitives/InitCode/index.ts:25

Parameters

value

string | Uint8Array<ArrayBufferLike> | InitCodeType

Returns
