# EncodedData

> ABI-encoded hex data

# EncodedData

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

## Type

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

## Construction

```typescript theme={null}
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

```typescript theme={null}
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);
```
