# Bridge to Base

> Move ETH, stablecoins, and tokens to and from Base — from a Coinbase account, Ethereum, Solana, or Bitcoin.

Move assets to and from Base using the routes below. Pick the one that matches where your assets are today.

## Choose a Route

| Coming from | Recommended route | Typical assets |
| - | - | - |
| A Coinbase account | Withdraw directly to Base (no bridge) | ETH, USDC, cbBTC |
| Ethereum (L1) | [Superbridge](https://superbridge.app/?fromChainId=1\&toChainId=8453) or [Brid.gg](https://www.brid.gg/?fromChainId=1\&toChainId=8453) | ETH, ERC-20s |
| Solana | [Base–Solana bridge](/specifications/base-protocol/bridging/base-solana-bridge) | SOL, SPL tokens |
| Bitcoin | [Garden](https://app.garden.finance/?output-chain=base\&output-asset=cbBTC) | BTC → cbBTC |

<Note>
  If you hold funds in a Coinbase account, you can withdraw many assets straight onto the Base network — select **Base** as the network when withdrawing, no bridge required. This is often the fastest path for USDC and ETH.
</Note>

## USDC on Base

USDC on Base is issued natively by Circle. Use the native USDC contract for new integrations. Circle publishes the canonical address for every network on its [USDC contract addresses](https://developers.circle.com/stablecoins/usdc-contract-addresses) page.

| Token | Network | Address | Issuer |
| - | - | - | - |
| USDC | Base Mainnet | `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` | Circle (native) |
| USDC | Base Sepolia | `0x036CbD53842c5426634e7929541eC2318f3dCF7e` | Circle (native) |
| USDbC (USD Base Coin) | Base Mainnet | `0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA` | Bridged from Ethereum |

USDbC is the earlier bridged form of USDC. It is a Standard Bridge token: Ethereum USDC (`0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48`) is locked on L1 and USDbC is minted on Base by the `L2StandardBridge` predeploy (`0x4200000000000000000000000000000000000010`). Circle does not issue USDbC, and it is a separate token from native USDC. To move from USDbC to native USDC, swap it onchain, or withdraw it to Ethereum through the Standard Bridge. The [Superchain token list](https://github.com/ethereum-optimism/ethereum-optimism.github.io/blob/master/data/BridgedUSDC/data.json) records the USDbC mapping.

To move native USDC between Base and other networks, use Circle's [Cross-Chain Transfer Protocol (CCTP)](https://developers.circle.com/cctp). CCTP burns USDC on the source chain and mints native USDC on the destination chain, so no bridged representation is created. Base is CCTP domain `6`. For the list of supported chains, see [CCTP supported blockchains](https://developers.circle.com/cctp/cctp-supported-blockchains).

### Other Stablecoins

Circle also issues EURC, a euro stablecoin, natively on Base:

| Token | Network | Address | Issuer |
| - | - | - | - |
| EURC | Base Mainnet | `0x60a3E35Cc302bFA44Cb288Bc5a4F316Fdb1adb42` | Circle (native) |
| EURC | Base Sepolia | `0x808456652fdb597867f38412077A9182bf77359F` | Circle (native) |

Confirm addresses on the issuer's own page ([EURC contract addresses](https://developers.circle.com/stablecoins/eurc-contract-addresses)) before you integrate. Stablecoins created with the [B20 Stablecoin variant](/get-started/issue-stablecoins) carry a self-declared `currency()` code; B20 checks the format of that code, not the issuer or its reserves.

## From Ethereum

Bridge ETH and supported ERC-20s between Ethereum mainnet (L1) and Base. Both providers support mainnet and Sepolia testnet.

### Programmatic Bridging

To bridge ETH and ERC-20s from Ethereum to Base in code, start from the [sample repository](https://github.com/base-org/guides/tree/main/bridge/native).

<Warning>
  **Double-check the token address for ERC-20s.** Confirm the token has a `base` entry in the [Superchain token list](https://github.com/ethereum-optimism/ethereum-optimism.github.io/tree/master/data) ([example](https://github.com/ethereum-optimism/ethereum-optimism.github.io/blob/master/data/WETH/data.json#L16-L18)), and always test with small amounts first. This sample bridges assets **to** Base only — do not modify it to withdraw.
</Warning>

### For Token Issuers

If you have an ERC-20 on Ethereum and want to enable bridging to Base, use the sample repository above as a starting point for the standard bridge contracts, then list your token on the Superchain token list.

## From Solana

The Base–Solana bridge enables bidirectional token transfers and message passing between Base and Solana: move SOL and SPL tokens, send cross-chain messages, deploy wrapped tokens on either chain, and optionally auto-relay for instant execution.

## From Bitcoin

[Garden](https://app.garden.finance/?output-chain=base\&output-asset=cbBTC) is a fast, non-custodial bridge for moving BTC and other supported assets to Base. Available on [mainnet](https://app.garden.finance/?output-chain=base\&output-asset=cbBTC) and [Sepolia testnet](https://testnet.garden.finance/?output-chain=base_sepolia\&output-asset=USDT).

<Note>
  The bridge previously at bridge.base.org has been deprecated. Use the routes above instead.
