## Transaction Types

Paxeer supports most Ethereum transaction types. The one notable exception is blob transactions.

## Supported Types

| Type | EIP | Name | Paxeer support |
| --- | --- | --- | --- |
| 0 | - | Legacy | Supported - governance-set minimum gas price applies |
| 1 | EIP-2930 | Access list | Supported |
| 2 | EIP-1559 | Fee market | Supported - base fee is not burned |
| 4 | EIP-7702 | Set code | Supported |

## Not Supported

| Type | EIP | Name | Notes |
| --- | --- | --- | --- |
| 3 | EIP-4844 | Blob | Not supported - Paxeer runs Pectra without blob transactions |

## Blob Transactions

Paxeer runs the Pectra hardfork without blob transaction support. Attempting to send a type 3 transaction will be rejected at the RPC level.

If you are porting code from Ethereum that uses blob transactions (e.g. rollup data availability), that path does not apply to Paxeer.

## Sending Transactions

Standard library defaults work correctly. viem, wagmi, and ethers all default to type 2 (EIP-1559) transactions on chains that support it, which Paxeer does.

<CodeGroup>

```ts viem
import { createWalletClient, http, parseEther } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { sei } from 'viem/chains';

const account = privateKeyToAccount('0xYourPrivateKey');
const client = createWalletClient({ account, chain: sei, transport: http() });

// Sends a type 2 transaction - correct default for Paxeer
const hash = await client.sendTransaction({
  to: '0xRecipient',
  value: parseEther('1'),
});
```

```ts ethers
import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://evm-rpc.sei-apis.com');
const wallet = new ethers.Wallet('0xYourPrivateKey', provider);

// ethers defaults to EIP-1559 where supported - correct for Paxeer
const tx = await wallet.sendTransaction({
  to: '0xRecipient',
  value: ethers.parseEther('1'),
});
```
