Move the bid asset onto the auction’s chain, then submit it there. A bridge transfers tokens between networks; it does not place a bid or guarantee that an auction will accept the tokens you receive.
What needs to arrive before you bid?
Find the auction’s official rules and confirm its network, accepted token, opening and closing times, and bid method. If the auction is on Mantle and your funds are elsewhere, a Mantle bridge swap service can move supported assets across chains for this part of the task; you still submit the bid through the auction’s own contract or interface. Check the token’s contract address, too: tokens with the same name can be different assets.
At mantlebridge.us, you would arrange a cross-chain move into Mantle when that route and asset are supported. Before sending funds, make sure you can also pay the destination network’s transaction fee; on Mantle, that means having MNT available.
How do you fund and submit a bid?
- Read the auction terms. Write down the required network and token, minimum bid, deadline, and whether bids can be changed or withdrawn. Check whether the auction uses a direct bid or a commit-and-reveal process, where you submit a hidden bid first and reveal it later.
- Calculate the amount to move. Add your intended bid to a small allowance for transaction fees. For example, if you plan to bid 40 USDC and expect to spend about 0.50 USDC on fees, aim to arrive with roughly 40.50 USDC, plus MNT for Mantle transaction fees. These are example amounts; check the auction and wallet for actual costs.
- Bridge the funds to the required network. Select the auction’s exact destination chain and accepted asset, then review the transfer details before confirming. A bridge transfer may take longer than a normal on-chain transaction, so leave time before the auction closes. Wait for the destination balance to appear; a completed send on the source chain alone does not mean the funds are ready to bid.
- Submit the bid from the destination wallet. Connect the wallet holding the arrived tokens, enter an amount within your available balance, and review the transaction before signing. For commit-and-reveal auctions, save the reveal details and complete that second action before its deadline.
What should you verify afterward?
Check the auction’s recorded bid or transaction status on Mantle, then follow its stated settlement and claim rules. A winning bid may require a separate claim, while an unsuccessful bid may need to be withdrawn or refunded through the auction process. I would bridge only the amount I intend to bid, keep fee funds separate, and verify the auction’s accepted token contract before moving anything.
