Bridge to Robinhood Chain from Ethereum, Base and Arbitrum
TrnchLabs
How to bridge ETH and stablecoins to Robinhood Chain (chain ID 4663) from Ethereum, Base or Arbitrum with your own wallet: what you need, the steps, gas, and the mistakes to avoid.
Robinhood Chain is an EVM Layer 2, so the wallet you use on Ethereum, Base or Arbitrum works there too. To trade on it, you first need funds on the chain. The Trnch Bridge moves ETH or stablecoins from Ethereum, Base or Arbitrum to Robinhood Chain in one signature from your own wallet.
What you need
- An EVM wallet such as MetaMask or Rabby, with funds on Ethereum, Base or Arbitrum.
- A little ETH on the source chain to pay its gas.
- Robinhood Chain added to your wallet (chain ID 4663). Trnch asks your wallet to add it for you when you connect.
How to bridge
- Open trnch.fun/bridge and connect your wallet.
- Pick the source chain: Ethereum, Base or Arbitrum, and the token you send, such as ETH, USDC or USDT.
- Pick what you receive on Robinhood Chain: ETH for gas and trading, or USDG to hold dollars.
- Check the quote: what you send, what you receive and the route, then sign in your wallet.
- Funds arrive at the same address on Robinhood Chain. Track the transaction on robinhoodchain.blockscout.com.
Get gas first
Gas on Robinhood Chain is paid in ETH. If you receive only USDG, you will not be able to send a transaction. Receive some ETH on your first bridge; with no gas yet, the Bridge opens on ETH to ETH.
Mistakes to avoid
- Sending tokens straight to a contract address or an exchange deposit address on Robinhood Chain. Bridge to your own wallet.
- Bridging from fake sites. Check the address bar: trnch.fun only.
- Approving more than you bridge. Revoke old approvals with Revoke in Trnch Tools.
- Sharing your recovery phrase. Nobody from Trnch will ever ask for it.
After the bridge
Once your funds are on Robinhood Chain, swap them on Trnch: each swap is quoted across KyberSwap, LI.FI, Uniswap, 0x, SushiSwap and 1inch, and built for your wallet to sign. Coming from Solana instead? Use the Solana side of the Trnch Bridge with Phantom, Solflare or Backpack.
