Base L2 Development

Base is Coinbase's L2 built on Optimism's OP Stack. It shares Ethereum security, uses ETH as gas, and settles to L1. If you can deploy to Ethereum, you can deploy to Base with zero code changes — just point at a different RPC.

What You Probably Got Wrong

  • Base is NOT a separate EVM — It is an OP Stack rollup. Same opcodes, same Solidity compiler, same tooling. There is nothing "Base-specific" about contract development. If your contract works on Ethereum or Optimism, it works on Base.
  • Gas has two components — L2 execution gas (cheap, ~0.001 gwei base fee) plus L1 data fee (variable, depends on Ethereum blob fees). The L1 data fee is the dominant cost for most transactions. After EIP-4844 (Dencun), L1 data costs dropped ~100x.
  • msg.sender works differently with Smart Wallet — Coinbase Smart Wallet is a smart contract account (ERC-4337). msg.sender is the smart wallet address, not the EOA. If your contract checks tx.origin == msg.sender to block contracts, it will block Smart Wallet users.
  • OnchainKit is NOT a wallet library — It is a React component library for building Base-native UIs. It handles identity resolution, transaction submission, token swaps, and Farcaster frames. You still need wagmi/viem for the underlying wallet connection.
  • Paymaster does NOT mean free transactions — A paymaster sponsors gas on behalf of users. Someone still pays. You configure a Coinbase Developer Platform paymaster policy that defines which contracts and methods are sponsored, with spend limits.
  • Block time is 2 seconds — Not 12 seconds like Ethereum L1. Plan your polling and confirmation logic accordingly.
  • Basescan and Blockscout are both available — Basescan (Etherscan-based) is the primary explorer. Blockscout is the alternative. Contract verification works on both but uses different APIs.

OnchainKit

OnchainKit is Coinbase's React component library for building onchain apps on Base. It provides ready-made components for identity, transactions, swaps, wallets, and Farcaster frames.

Installation

npm install @coinbase/onchainkit
# Peer dependencies
npm install viem wagmi @tanstack/react-query

Provider Setup

import { OnchainKitProvider } from '@coinbase/onchainkit';
import { base } from 'viem/chains';

function App({ children }: { children: React.ReactNode }) {
  return (
    <OnchainKitProvider
      apiKey={process.env.NEXT_PUBLIC_CDP_API_KEY}
      chain={base}
    >
      {children}
    </OnchainKitProvider>
  );
}

Identity Components

Resolve onchain identity (ENS, Basenames, Farcaster):

import {
  Identity,
  Name,
  Avatar,
  Badge,
  Address,
} from '@coinbase/onchainkit/identity';

function UserProfile({ address }: { address: `0x${string}` }) {
  return (
    <Identity address={address} schemaId="0x...">
      <Avatar />
      <Name>
        <Badge />
      </Name>
      <Address />
    </Identity>
  );
}

Transaction Component

Submit transactions with built-in status tracking:

import { Transaction, TransactionButton, TransactionStatus } from '@coinbase/onchainkit/transaction';
import { baseSepolia } from 'viem/chains';

const contracts = [
  {
    address: '0xContractAddress' as `0x${string}`,
    abi: contractAbi,
    functionName: 'mint',
    args: [1n],
  },
];

function MintButton() {
  return (
    <Transaction
      chainId={baseSepolia.id}
      contracts={contracts}
      onStatus={(status) => console.log('tx status:', status)}
    >
      <TransactionButton text="Mint NFT" />
      <TransactionStatus />
    </Transaction>
  );
}

Swap Component

Token swaps powered by 0x/Uniswap:

import { Swap, SwapAmountInput, SwapButton, SwapToggle } from '@coinbase/onchainkit/swap';
import type { Token } from '@coinbase/onchainkit/token';

const ETH: Token = {
  name: 'Ethereum',
  address: '',
  symbol: 'ETH',
  decimals: 18,
  image: 'https://...',
  chainId: 8453,
};

const USDC: Token = {
  name: 'USD Coin',
  address: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
  symbol: 'USDC',
  decimals: 6,
  image: 'https://...',
  chainId: 8453,
};

function SwapWidget() {
  return (
    <Swap>
      <SwapAmountInput label="Sell" token={ETH} type="from" />
      <SwapToggle />
      <SwapAmountInput label="Buy" token={USDC} type="to" />
      <SwapButton />
    </Swap>
  );
}

Wallet Component

import {
  ConnectWallet,
  Wallet,
  WalletDropdown,
  WalletDropdownDisconnect,
} from '@coinbase/onchainkit/wallet';

function WalletConnect() {
  return (
    <Wallet>
      <ConnectWallet>
        <Avatar />
        <Name />
      </ConnectWallet>
      <WalletDropdown>
        <Identity />
        <WalletDropdownDisconnect />
      </WalletDropdown>
    </Wallet>
  );
}

Smart Wallet

Coinbase Smart Wallet is a smart contract wallet using passkeys (WebAuthn) for authentication. It follows ERC-4337 (account abstraction) so users do not need a seed phrase or browser extension.

How It Works

  1. User creates wallet via passkey (fingerprint, Face ID, or security key)
  2. A smart contract wallet is deployed on Base (counterfactual — deployed on first transaction)
  3. Transactions are signed with the passkey and submitted as UserOperations
  4. Compatible with ERC-4337 bundlers and paymasters

wagmi + Smart Wallet

import { http, createConfig } from 'wagmi';
import { base, baseSepolia } from 'wagmi/chains';
import { coinbaseWallet } from 'wagmi/connectors';

export const config = createConfig({
  chains: [base, baseSepolia],
  connectors: [
    coinbaseWallet({
      appName: 'My Base App',
      // preference: 'smartWalletOnly' forces smart wallet (no extension)
      preference: 'smartWalletOnly',
    }),
  ],
  transports: {
    [base.id]: http(),
    [baseSepolia.id]: http(),
  },
});

Sending Transactions from Smart Wallet

import { useWriteContract } from 'wagmi';

function MintWithSmartWallet() {
  const { writeContract } = useWriteContract();

  const handleMint = () => {
    writeContract({
      address: '0xContractAddress',
      abi: contractAbi,
      functionName: 'mint',
      args: [1n],
    });
  };

  return <button onClick={handleMint}>Mint</button>;
}

Batch Transactions (EIP-5792)

Smart Wallet supports wallet_sendCalls for atomic batching:

import { useWriteContracts } from 'wagmi/experimental';

function BatchMint() {
  const { writeContracts } = useWriteContracts();

  const handleBatch = () => {
    writeContracts({
      contracts: [
        {
          address: '0xTokenAddress',
          abi: erc20Abi,
          functionName: 'approve',
          args: ['0xSpender', 1000000n],
        },
        {
          address: '0xSpender',
          abi: spenderAbi,
          functionName: 'deposit',
          args: [1000000n],
        },
      ],
    });
  };

  return <button onClick={handleBatch}>Approve + Deposit</button>;
}

Paymaster (Gasless Transactions)

A paymaster sponsors gas fees so users pay zero gas. Coinbase Developer Platform provides a paymaster service for Base.

Setup

  1. Create a project at portal.cdp.coinbase.com
  2. Enable the Paymaster service
  3. Configure a paymaster policy (which contracts/methods to sponsor)
  4. Get your paymaster URL: https://api.developer.coinbase.com/rpc/v1/base/$CDP_API_KEY

wagmi + Paymaster (EIP-5792)

import { useWriteContracts } from 'wagmi/experimental';
import { base } from 'viem/chains';

const PAYMASTER_URL = `https://api.developer.coinbase.com/rpc/v1/base/${process.env.NEXT_PUBLIC_CDP_API_KEY}`;

function SponsoredMint() {
  const { writeContracts } = useWriteContracts();

  const handleMint = () => {
    writeContracts({
      contracts: [
        {
          address: '0xContractAddress',
          abi: contractAbi,
          functionName: 'mint',
          args: [1n],
        },
      ],
      capabilities: {
        paymasterService: {
          url: PAYMASTER_URL,
        },
      },
    });
  };

  return <button onClick={handleMint}>Mint (Gasless)</button>;
}

Viem + Paymaster (Direct UserOperation)

import { createPublicClient, http, encodeFunctionData } from 'viem';
import { base } from 'viem/chains';

const PAYMASTER_URL = `https://api.developer.coinbase.com/rpc/v1/base/${process.env.CDP_API_KEY}`;

async function sponsoredCall(
  smartWalletAddress: `0x${string}`,
  target: `0x${string}`,
  calldata: `0x${string}`
) {
  const client = createPublicClient({
    chain: base,
    transport: http(),
  });

  // pm_getPaymasterStubData returns gas estimates for the UserOp
  const paymasterResponse = await fetch(PAYMASTER_URL, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      jsonrpc: '2.0',
      id: 1,
      method: 'pm_getPaymasterStubData',
      params: [
        {
          sender: smartWalletAddress,
          callData: calldata,
          callGasLimit: '0x0',
          verificationGasLimit: '0x0',
          preVerificationGas: '0x0',
          maxFeePerGas: '0x0',
          maxPriorityFeePerGas: '0x0',
        },
        // EntryPoint v0.7
        '0x0000000071727De22E5E9d8BAf0edAc6f37da032',
        `0x${base.id.toString(16)}`,
      ],
    }),
  });

  return paymasterResponse.json();
}

Paymaster Policy

Configure which transactions are sponsored in the Coinbase Developer Platform dashboard:

  • Contract allowlist — Only sponsor calls to specific contract addresses
  • Method allowlist — Only sponsor specific function selectors
  • Spend limits — Max gas per user per day/week/month
  • Rate limits — Max sponsored txs per user per time window

Bridging

Base uses the OP Stack standard bridge. ETH and ERC-20 tokens can be bridged between Ethereum L1 and Base L2.

Bridge ETH to Base (L1 -> L2)

import { createWalletClient, http, parseEther } from 'viem';
import { mainnet } from 'viem/chains';
import { privateKeyToAccount } from 'viem/accounts';

// OptimismPortal on L1 (Ethereum mainnet)
const OPTIMISM_PORTAL = '0x49048044D57e1C92A77f79988d21Fa8fAF36f97B' as const;

const walletClient = createWalletClient({
  chain: mainnet,
  transport: http(),
  account: privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`),
});

// Deposit ETH to Base — sends to OptimismPortal with value
const hash = await walletClient.sendTransaction({
  to: OPTIMISM_PORTAL,
  value: parseEther('0.1'),
  // depositTransaction calldata for simple ETH transfer
  data: '0x',
});
// ETH arrives on Base in ~1-5 minutes

Bridge ETH from Base (L2 -> L1)

L2-to-L1 withdrawals follow the OP Stack withdrawal flow:

  1. Initiate withdrawal on L2 (sends message to L2ToL1MessagePasser)
  2. Wait for state root to be posted on L1 (~1 hour)
  3. Prove withdrawal on L1 (submit Merkle proof)
  4. Wait for challenge period (~7 days on mainnet)
  5. Finalize withdrawal on L1
import { createPublicClient, createWalletClient, http, parseEther } from 'viem';
import { base } from 'viem/chains';

// L2ToL1MessagePasser predeploy on Base
const L2_TO_L1_MESSAGE_PASSER = '0x4200000000000000000000000000000000000016' as const;

const l2WalletClient = createWalletClient({
  chain: base,
  transport: http(),
  account: privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`),
});

// Step 1: Initiate withdrawal on L2
const hash = await l2WalletClient.writeContract({
  address: L2_TO_L1_MESSAGE_PASSER,
  abi: [
    {
      name: 'initiateWithdrawal',
      type: 'function',
      stateMutability: 'payable',
      inputs: [
        { name: '_target', type: 'address' },
        { name: '_gasLimit', type: 'uint256' },
        { name: '_data', type: 'bytes' },
      ],
      outputs: [],
    },
  ],
  functionName: 'initiateWithdrawal',
  args: [
    l2WalletClient.account.address, // send to self on L1
    100_000n, // L1 gas limit for the relay
    '0x',
  ],
  value: parseEther('0.1'),
});
// Steps 2-4 require waiting and L1 transactions (use the Base Bridge UI or OP SDK)

Gas Model

Base follows the OP Stack gas model: L2 execution fee + L1 data fee.

L2 Execution Fee

Same as Ethereum: gasUsed * baseFee. Base uses EIP-1559 with a 2-second block time. Base fees are typically very low (0.001-0.01 gwei).

L1 Data Fee

Every L2 transaction is posted to Ethereum L1 as calldata or blobs. The L1 data fee covers this cost.

After EIP-4844 (Dencun upgrade, March 2024), L1 data is posted as blobs, reducing costs ~100x.

import { createPublicClient, http } from 'viem';
import { base } from 'viem/chains';

// GasPriceOracle predeploy
const GAS_PRICE_ORACLE = '0x420000000000000000000000000000000000000F' as const;

const gasPriceOracleAbi = [
  {
    name: 'getL1Fee',
    type: 'function',
    stateMutability: 'view',
    inputs: [{ name: '_data', type: 'bytes' }],
    outputs: [{ name: '', type: 'uint256' }],
  },
  {
    name: 'baseFeeScalar',
    type: 'function',
    stateMutability: 'view',
    inputs: [],
    outputs: [{ name: '', type: 'uint32' }],
  },
  {
    name: 'blobBaseFeeScalar',
    type: 'function',
    stateMutability: 'view',
    inputs: [],
    outputs: [{ name: '', type: 'uint32' }],
  },
] as const;

const client = createPublicClient({ chain: base, transport: http() });

// Estimate L1 data fee for a transaction
const l1Fee = await client.readContract({
  address: GAS_PRICE_ORACLE,
  abi: gasPriceOracleAbi,
  functionName: 'getL1Fee',
  args: ['0x...serializedTxData'],
});

Gas Estimation Tips

  • Total cost = L2 execution fee + L1 data fee
  • L1 data fee dominates for simple transactions
  • Minimize calldata size to reduce L1 costs (pack structs, use shorter data)
  • eth_estimateGas returns L2 gas only — add L1 data fee separately
  • viem's estimateTotalFee on OP Stack chains handles both components

  USDC,
  getProgramAndBitflagByProtocolName,
} from "@glamsystems/glam-sdk";
import { BN } from "@coral-xyz/anchor";

const client = new GlamClient({ wallet });

// Create vault
const { vaultPda } = await client.vault.create({

});

// Enable Jupiter integration
const perms = getProgramAndBitflagByProtocolName();
const [program, bitflag] = perms["JupiterSwap"];
await client.access.enableProtocols(vaultPda, program, parseInt(bitflag, 2));

// Swap
await client.jupiterSwap.swap(vaultPda, {
  inputMint: USDC,
  outputMint: WSOL,
  amount: new BN(100_000_000),
