Both Ethereum and Base are standout successes in the blockchain ecosystem. Ethereum, the first smart contract platform, pioneered decentralized applications and remains the foundation for DeFi, NFTs, and DAOs. Its security and network effects make it the most widely used Layer 1 blockchain in terms of daily network activity.
Base, launched by Coinbase on August 9, 2023, is a fast-rising Layer 2 solution built to scale Ethereum. It leverages the OP Stack and optimistic rollups to offer low-cost, high-speed transactions while inheriting Ethereum’s security. Built on open-source standards, Base quickly gained traction thanks to its developer-friendly environment and backing from one of the industry’s largest exchanges. In less than a year, it has become one of the most active L2s, supporting a growing ecosystem of DeFi apps, games, and social protocols.
What Is the Base to ETH Bridge?
The Base to ETH Bridge by ChainPort is a security-focused token bridge that enables fast and secure transfers of ERC-20 tokens between Base and Ethereum. Designed with advanced security architecture, the bridge ensures users can move assets between chains with confidence and minimal risk.
By supporting seamless interoperability between Base and Ethereum, ChainPort’s bridge helps users access liquidity, DeFi protocols, and dApps across both ecosystems.
Why Bridge from Base to Ethereum?
Bridging tokens from Base to Ethereum unlocks greater exposure and utility for projects and users alike. By moving assets to Ethereum, tokens gain access to a larger and more established user base, increasing visibility and potential adoption. This cross-chain presence can drive higher trading volume and increase listings on more DEXs, enhancing liquidity.
Bridging also enables participation in Ethereum-native DeFi protocols, broadening a token’s utility across ecosystems.
How to Bridge Tokens from Base to Ethereum in 4 Steps
Step 1 - Connect Your Wallet
Go to ChainPort's bridge (https://app.chainport.io/) and connect your wallet. ChainPort supports Ledger, Trezor, Coinbase Wallet, Wallet Connect, and Metamask wallets. Select the wallet with the Base-based tokens you wish to bridge to Ethereum.
Step 2 - Select the Chains & Token
In the drop-down menu, select the source blockchain and token. In our case, the source chain is Base. Select Ethereum as the target chain.
Step 3 - Confirm Tx & Get Tokens
Review all the related information, such as gas fees and the token, before confirming the transaction. Once you have confirmed all details, approve the transaction and wait a few minutes for it to be processed. Afterward, your tokens have been bridged from Base to Ethereum.
What are the Bridging Fees?
ChainPort applies a simple, transparent 0.3% fee on each bridging transaction, one of the lowest rates among cross-chain bridges. This fee supports the protocol’s sustainability, including security audits and continuous development. Users always maintain full custody of their tokens during bridging.
Gas fees are also required, but they’re generally low.
How Long Does the Transfer Take?
Bridging tokens from Base to Ethereum typically takes just a few minutes. However, during periods of high network congestion, the process may take longer than expected.
You can check the status of your transaction for real-time updates during the bridging process or contact ChainPort’s support in case of a delay.
Is Bridging Safe?
Bridging can be safe when using trusted protocols like ChainPort. ChainPort prioritizes security through a robust multi-layered model, including multisig wallets, strict access controls, and continuous monitoring.
The bridge has undergone multiple smart contract audits by leading blockchain security firms to ensure safety and reliability. By combining advanced security practices with transparent audit results, ChainPort offers users peace of mind when transferring tokens between Base and Ethereum.
While no system is completely risk-free, ChainPort’s security-first approach significantly reduces the chances of exploits or vulnerabilities during the bridging process.
