How to use cbridge to move tokens between chains
Learn how cBridge moves tokens between chains, what its receive estimate and fees mean, and what to check before you confirm a transfer with your wallet.

cbridge lets you move supported tokens between blockchains by sending a transfer from one network and receiving tokens on another. The practical steps are to connect a wallet, choose the two chains and token, review the amount you should receive, then confirm the transactions. The route and token type affect the final amount.
How do you start a cbridge transfer?
Celer’s transfer instructions say to connect a wallet, select the source and destination chains, and enter the amount. The wallet needs to be on the source chain, where you pay the transaction fee, often called gas. If the token is new to that wallet, you may first need to approve the contract to spend it. That approval is a separate wallet transaction.
For example, if you are moving a supported stablecoin from one network to another, check both chain names and the token before entering an amount. You can review the options at cbridge. The displayed receive estimate reflects the bridge rate and fees; it can be lower than the amount sent.
- Connect the wallet holding the tokens.
- Select the source chain, destination chain and token.
- Enter an amount and review the estimated receive amount and fees.
- Approve the token if prompted, then confirm the transfer in your wallet.
Why can the amount received differ?
The bridge model determines what happens to the token. Celer’s documentation describes xAsset as a lock-and-mint route: tokens are locked on the source chain, and a mapped version is minted on the destination. Its xLiquidity model uses pools on both chains: tokens go into a source pool and matching tokens come out of a destination pool. A pool’s available funds and bridge rate can affect how much arrives.
Fees also reduce the received amount. Celer lists a base fee to cover destination-chain gas and a protocol fee. The transfer screen shows an estimate before you confirm, so compare the amount received with the amount sent. Slippage is the possible change in the rate while a transfer is processed. A setting that is too tight can cause a transfer to fail, while a looser setting allows more rate movement.
What should you check before confirming?
Check the destination chain and token carefully. The same ticker can refer to a mapped version on another chain, and a token may need to be added to your wallet before it appears. Keep enough of the source chain’s native token to pay gas. Confirm only after the wallet transaction matches the route and amount shown on cbridge.
After you submit, use the transfer status or transaction history to follow progress, then check the destination wallet on the selected chain. If a transfer fails, Celer’s instructions say the transfer history may offer a refund request. For most users, the best choice is to use a route with a clear receive estimate and enough liquidity, and to treat the destination token’s identity as part of the decision.
