How to Bridge to Coinbase Base

Bottom Line: As Coinbase Base is still a relatively new chain, only four supported bridging platforms allow users to transfer funds to the Layer 2 network. Out of all the available options, Synapse Protocol is the best choice as it offers the widest range of bridgeable assets, the lowest fees, the fastest transaction speeds, and provides the most secure platform.

How to Bridge to Coinbase Base

The best way for traders to bridge their assets to the Coinbase Base network is by going through a secure and trusted bridging platform. As previously mentioned, we recommend using Synapse protocol as it allows direct access to Base and 18 other blockchains. Simply connect your wallet (MetaMask, Rainbow, Coinbase Wallet or Wallet Connect) to Synapse and begin the transfer process.

Get started with this step-by-step guide:

  1. Go to Synapse Protocol and collect your Web 3 wallet.
  2. Select your origin network (where you’re transferring your assets from) and choose ‘Base’ as your destination chain. 
  3. Pick your desired bridging token and input the amount you want to transfer to Base.
  4. Click ‘Bridge’ and follow the prompts in your wallet. The funds will be credited within minutes.

Base Bridging Costs

The costs to bridge funds to Base will vary depending on the platform you use and what token you are transferring. If you use the Synapse protocol, the costs are relatively low as it provides minimal slippage and takes a small 0.1% bridging fee. You can see the total amount the platform takes when you review the prompts in your MetaMask or other Web 3 wallet.

How does Base Bridging Work?

Coinbase Base operates by transferring tokens from one blockchain, such as Ethereum, to the Coinbase Base network. This is made possible through a cross-chain bridge which serves as a linkage among these platforms. The function of the bridge involves dispatching tokens to a designated smart contract address within the original network. This address temporarily secures the tokens in a kind of escrow while the bridge spawns an equivalent volume of tokens on the Coinbase Base network.

What is Coinbase Base?

Base is an Ethereum Layer 2 blockchain network incubated within Coinbase, aimed at providing a secure, affordable, and developer-friendly platform for building decentralized applications (dApps). Built on the OP Stack in collaboration with Optimism, Base leverages the inherent security of the Ethereum network, alongside Coinbase's best practices, to confidently allow users to transition into Base from Ethereum L1, Coinbase, and other interoperable chains. 

One of the defining features of Base includes full Ethereum Virtual Machine (EVM) compatibility, offering the same environment at significantly lower costs. Base enables developers to set up gasless transactions through simple APIs, thereby facilitating the development of multi-chain applications. Furthermore, it allows seamless integration with Coinbase products, providing easy access to fiat onramps and Coinbase's wide user base. In its pursuit of creating a modular, rollup agnostic Superchain, Base is committed to becoming an open-source, permissionless platform. 

The Bottom Line

To recap, Coinbase Base represents an important step forward in the world of blockchain as an Ethereum Layer 2 solution that brings secure, affordable, and developer-friendly capacities to decentralized application (dApp) development. Bridging to Coinbase Base, though currently supported by only four platforms, can be easily and effectively done through Synapse Protocol, which stands out for its asset diversity, low fees, speedy transactions, and high security.
