wBTCN: unwrap to BTCN first

wBTCN doesn't bridge directly. Unwrap it to native BTCN, then bridge the BTCN.

wBTCN is the wrapped (ERC-20) form of native BTCN — analogous to WETH on Ethereum. It exists so smart contracts can hold and move BTCN, since native BTCN is the gas token.

There is no direct bridge for wBTCN. To exit Corn:

  1. Unwrap wBTCN → native BTCN (one transaction on Corn).

  2. Bridge native BTCN to Ethereum via the Corn Bridge app.

Step 1 — Unwrap

The wBTCN contract is a standard wrapped-native pattern. To unwrap:

  1. Go to the wBTCN contract on Cornscan.

  2. Click the Contract tab → Write Contract → Connect Wallet.

  3. Find the withdraw function. Enter the wBTCN amount (in raw units — multiply by 10^18; or just paste your full balance from the Read Contract → balanceOf query).

  4. Click Write and confirm in your wallet.

  5. Native BTCN appears in your wallet balance immediately after the transaction confirms.

Step 2 — Bridge native BTCN

Once you have BTCN, follow Bridging native BTCN to Ethereum. Same flow as any LayerZero bridge through the Corn Bridge app.

Why is wBTCN here at all?

Many Corn protocols (Morpho markets, Uniswap V3 pairs) operate in wBTCN because they need a real ERC-20 token. If you've exited any of those protocols, you may receive wBTCN. The unwrap is a one-line transaction.

Help

If the unwrap fails or wBTCN balance shows zero after a confirmed transaction, ping us in the Corn Discord.
