The Corn Bridge app is our LayerZero-powered UI for moving assets between Corn and Ethereum mainnet. It's the default path for the vast majority of assets on Corn.
Use this guide if you hold: CORN, USDT0, USDC, LBTC, aBTC, waBTC, eBTC, weETH, wETH, solvBTC, SolvBTC.BBN (xSolvBTC), stBTC, enzoBTC, sUSDa, USDa, BTCN.
You can also bridge any LayerZero-based asset via Stargate directly if you prefer their UI — the bridge contracts are the same.
Before you start
Add Corn to your wallet — see Connecting your wallet to Corn if you haven't.
Hold a small amount of BTCN in the wallet you're bridging from. You need BTCN to pay gas on Corn.
Don't bridge 100% of your BTCN. Leave enough for one or two more transactions in case you need them.
Step 1 — Open the bridge for your asset
Open the Bridge out page for your asset directly via one of these links:
Asset | Direct link |
BTCN | |
WBTC (post-swap) | |
CORN | |
USDT0 | |
USDC | |
LBTC | |
solvBTC | |
SolvBTC.BBN | |
waBTC | |
stBTC | |
enzoBTC | |
USDa | |
sUSDa | |
wETH | |
weETH |
Connect your wallet (top right) and make sure you're on the Corn network. The app will prompt you to switch if not.
Step 2 — Enter the amount and bridge
Enter the amount you want to bridge.
If the token requires it, you'll first see an APPROVE transaction — sign it. This authorises the bridge to spend your token.
After the approval confirms, click BRIDGE OUT. You'll see a transaction summary with the LayerZero fee. Confirm in your wallet.
The transaction submits on Corn first, then LayerZero relays it to Ethereum.
Step 3 — Watch the transaction status
The app's History tab shows the lifecycle of each bridge transaction:
Waiting — you've signed but the source-chain tx isn't final yet.
Inflight — source-chain tx is final; LayerZero relay in progress.
Confirmed — destination tx submitted.
Delivered — your asset has arrived in your wallet on Ethereum.
Most bridges complete within minutes. If you see "Delivered" but your wallet doesn't show the balance, you may need to import the token into your Ethereum-side wallet — see Known addresses for mainnet contract addresses.
Fees explained
The Corn Foundation charges no bridge fee.
LayerZero applies a small protocol fee to relay the message.
The gas fee you pay on Corn covers BOTH the Corn-side transaction AND the destination gas on Ethereum, bundled into one payment.
Alternative: bridging via Stargate
Any LayerZero-based asset can also be bridged through Stargate. The fee model and relay are the same — it's just a different front-end. Set the source chain to Corn and the destination to Ethereum (or whichever chain you want), pick the token, and follow the same steps.
Help
If a bridge transaction is stuck or doesn't show up on the destination chain, see I bridged but my asset hasn't arrived. For anything else, ping us in the Corn Discord.
