## Type Aliases

### ContractCodeType

> **ContractCodeType** = `Uint8Array` & `object`

Branded ContractCode type
Full deployed contract bytecode including metadata

#### Type Declaration

##### \[brand]

> `readonly` **\[brand]**: `"ContractCode"`

## Functions

### \_equals()

> **\_equals**(`a`, `b`): `boolean`

Defined in: [src/primitives/ContractCode/equals.js:15](https://github.com/evmts/voltaire/blob/bd6ec34405c15ad8cd51d11579d495dc53813482/src/primitives/ContractCode/equals.js#L15)

#### Parameters

##### a

[`ContractCodeType`](#contractcodetype)

First ContractCode

##### b

[`ContractCodeType`](#contractcodetype)

Second ContractCode

#### Returns

`boolean`

true if equal

#### Example

```javascript theme={null}
import * as ContractCode from './primitives/ContractCode/index.js';
const code1 = ContractCode.from("0x6001");
const code2 = ContractCode.from("0x6001");

Extract runtime code from contract code

Strips metadata to return pure runtime bytecode.
Alias for stripMetadata for semantic clarity.

#### Parameters

##### code

[`ContractCodeType`](#contractcodetype)

ContractCode

#### Returns

[`RuntimeCodeType`](RuntimeCode.mdx#runtimecodetype)

RuntimeCode

#### Example

```javascript theme={null}
import * as ContractCode from './primitives/ContractCode/index.js';

Check if contract code contains CBOR metadata

Solidity compiler includes CBOR-encoded metadata at the end of deployed bytecode.
The metadata section starts with 0xa2 (CBOR map) and ends with 0x00 0x33 (length).

#### Parameters

##### code

[`ContractCodeType`](#contractcodetype)

ContractCode to check

#### Returns

`boolean`

true if metadata is present

#### Example

```javascript theme={null}
import * as ContractCode from './primitives/ContractCode/index.js';
const code = ContractCode.from("0x6001600155a264...0033");
ContractCode._hasMetadata(code); // true

Strip CBOR metadata from contract code

Returns runtime code without the Solidity compiler metadata.

#### Parameters

##### code

[`ContractCodeType`](#contractcodetype)

ContractCode with metadata

#### Returns

[`RuntimeCodeType`](RuntimeCode.mdx#runtimecodetype)

RuntimeCode without metadata

#### Example

```javascript theme={null}
import * as ContractCode from './primitives/ContractCode/index.js';
const withMeta = ContractCode.from("0x6001600155a264...0033");
const runtime = ContractCode._stripMetadata(withMeta);
