Connecting your wallet to Corn

RPC, chain ID, and gas-token info to add Corn to MetaMask, Rabby, Coinbase Wallet, or Brave.

If you've never connected to Corn, or you're using a fresh wallet, add the network manually. The Corn chain is an EVM L2 (Conduit OP-Stack) and works with any standard EVM wallet.

You only need to do this once.

Gas

Corn uses BTCN as the gas token (it has 18 decimals, like ETH on Ethereum). Every transaction on Corn — including bridging, claiming, and protocol exits — needs a small amount of BTCN to cover gas.

If you arrive on Corn with no BTCN, you can't transact. Always keep a small amount of BTCN in your wallet until you're done with all your withdrawals. Bridging out 100% of your BTCN is the very last thing you do.

Verifying you're connected

Once you've added the network and switched to it in your wallet:

  1. Open cornscan.io and search your wallet address.

  2. The page should show your address with whatever balances you hold on Corn.

  3. If you see balances on Cornscan but not in your wallet, you need to import the token into your wallet. The token addresses are in Known addresses.

Help

If your wallet won't connect, your transactions revert with "insufficient gas," or balances aren't showing — ping us in the Corn Discord.
