- •Brid.gg is the simplest way to bridge ETH or ERC-20 tokens from Ethereum to Base, and transfers usually finish within a few minutes.
- •Always check gas fees before sending funds and bridge during quieter hours when Ethereum is less busy to save money on transactions.
- •Keep a small balance of ETH ready on Base so you can pay gas and interact with dApps the moment your tokens arrive.
You’re likely considering how to bridge to Base because Base has become one of the most active Layer 2 networks built on Ethereum. With over $5 billion+ TVL and rising transaction activity, as of 2025 Base is gaining traction among developers, DeFi users, and applications shifting toward low fee, high throughput environments.
Recently at BaseCamp 2025, Jesse Pollak announced that Base is exploring issuing a native network token. Plans are in early stages, none of the design, governance, or launch timing is finalized yet. This article walks you through how to bridge to Base via Brid.gg, explains two alternate bridges, covers security and troubleshooting, and gives insights so that your bridge transactions are as smooth (and safe) as possible.
Prerequisites
Before you bridge to Base, make sure you have:
1. A Web3 wallet such as MetaMask, already set up and funded, configured to connect with the Base network.
2. Enough ETH to pay gas once assets arrive on the network. You can acquire ETH for gas fees on Bitunix.
3. The correct Base Mainnet RPC/network added to your wallet (so you can view, receive, and interact with assets bridged in).

Step-by-Step Guide: Bridge to Base via Brid.gg
Brid.gg is a dedicated OP-Stack interface that connects Ethereum to Base and other Superchain networks. By default it uses the OP Standard Bridge for ETH and most ERC-20s, while USDC routes via Circle’s CCTP. Base’s docs list third-party bridges like Brid.gg since the native site was deprecated.
Open Brid.gg
Go to Brid.gg. This interface connects Ethereum to Base using the OP Standard Bridge for most assets.
Connect your wallet
Click Connect and choose your wallet such as MetaMask. Make sure you are on Ethereum Mainnet and have ETH for gas. Need gas fast? You can acquire ETH on Bitunix.
Select origin chain and token
In the From field choose Ethereum and select the token you want to bridge, for example ETH or USDC. For USDC, Brid.gg may route via Circle CCTP which appears in the interface.
Confirm destination: Base
The To field should display Base. If prompted, add or switch to the Base network in your wallet so you can see funds after they arrive.
Enter amount
Type the amount to bridge. Double check the destination address. It should be your own wallet on Base.
Review fees and details
Check the gas fee and the route Brid.gg displays. If Ethereum gas is high, wait for a quieter period to reduce cost.
Approve and bridge
Approve the token if required, then confirm the bridge transaction in your wallet. Funds usually show on Base a few minutes after the L1 transaction confirms.
Optional: withdraw back to Ethereum
If you withdraw from Base to Ethereum the OP Stack includes a challenge period of about 7 days before you can finalize on L1. Plan liquidity around this delay.
Expert Tip
Bridge during off-peak hours to cut fees. Keep a small ETH balance on both chains so you can approve and transact when funds land on Base.
Test with a small amount first. Track status on Etherscan and Basescan using your transaction hash.
Alternative Platforms
While Brid.gg is well-suited for most use cases, these other two options may fit better depending on your priorities:
Superbridge
Another bridge suggested by Base documentation. It supports ETH and ERC-20 token transfers between Ethereum and Base, using the OP Standard Bridge. If ease-of-use and minimal complexity are important, Superbridge offers a clean interface.
Matcha (Cross-Chain Swaps)
If you want to both bridge and convert (swap) tokens in one go, Matcha’s cross-chain swap feature aggregates different bridges and gives you flexibility. Useful if your destination token is not the same as what you’re starting with. You may face slightly higher fees or slippage, but you’ll avoid needing a separate swap transaction after bridging.
Security Considerations / Troubleshooting
Here are expert-level tips and common issues when you bridge to Base (or try to):
- Gas cost timing: Gas on Ethereum can spike. Monitor average gas prices (e.g., via tools like ETH Gas Station) and initiate bridging when gas is lower to reduce cost.
- Small test first: Always bridge a small amount first to confirm that everything works; wallet, network, asset, and token routing.
- Confirm token contract addresses: Especially for ERC-20 tokens, ensure you’re using official contract addresses; avoid similarly named or scam tokens.
- Withdrawal delays are normal: OP-chain security requires a challenge period (usually 7 days) when moving back to L1. Don’t expect instant return.
- Watch for failed transactions / stuck states: If your deposit doesn’t arrive after 3-5 minutes, verify via block explorers on both chains. If necessary, reach out to support via Brid.gg or Base community channels, providing transaction hash.
- Smart contract risk & audit history: Third-party bridges carry risk. Brid.gg is supported in Base documentation under “Superchain Bridges” but is not operated by Base itself. Review their documentation and consider risk exposure especially for large amounts.
Final Thoughts
Bridging to Base gives you access to a growing Layer 2 ecosystem where transaction costs are far lower than on Ethereum, and developers are shipping more tools, DeFi, and interoperability options. In 2025, with Base exploring a native token, being early in positioning (bridging and using assets on Base) may matter if and when token incentives or community governance emerge.
After you’ve bridged in, evaluate what you want to do next: swap into tokens you’ll use, interact with dApps, perhaps stake or provide liquidity. Make sure you keep some ETH on Base for gas. Also consider multi-chain asset strategy: bridging back, using Solana-Base bridges, etc.
FAQs
1. How long does it take for a bridge to complete when using Brid.gg?
Deposits (Ethereum → Base) via Brid.gg using the OP Standard Bridge usually take 1-3 minutes to arrive, once confirmed on Ethereum. Withdrawals (Base → Ethereum) take longer due to the fault-challenge period, often about 7 days.
2. Is there a fee for using Brid.gg to bridge to Base?
Brid.gg does not charge extra fees beyond what the underlying bridge and gas costs require. Some tokens may go through alternative routing (e.g. CCTP) which can have different costs. Always review the transaction details.
3. Can I use any wallet with Brid.gg when bridging to Base?
Most Web3 EVM wallets work. Just ensure the wallet supports connection via the bridged network, and that you control the private keys or access needed to receive assets on Base and send back to Ethereum if desired.
