Across bridge for cautious first-time users
The catch is that a bridge quote is not just a gas estimate. Your received amount depends on the route, token pair, liquidity, and the quote’s expiry. The figure that decides whether you should proceed is the quoted output: total fee = input amount − output amount. Check that number before signing, and never send funds to an address copied from a message.
When you choose a route, the quote reveals the real cost
Select the chain you are sending from, the destination chain, the token, and the amount. Compare the amount you will send with the expected amount you will receive after fees.
| What to inspect | What it tells you |
|---|---|
| Expected output | What should arrive after the current fee estimate |
| Minimum output | The lower bound shown for the transaction |
| Expected fill time | The current estimate for a relayer to complete the transfer |
| Transfer limits | Whether your amount qualifies for the selected route |
| Quote expiry | How long the displayed terms remain usable |
Fees can change with network gas prices, pool utilization, and route conditions, so a quote that has been sitting open is not evidence that the same terms still apply.
If the wallet and balances are ready, prepare the transaction
Connect the wallet that controls the source-chain funds, switch it to the sending network, and leave enough of that chain’s native asset to pay transaction gas. Confirm that the destination wallet address is yours and that you can use the received token there.
When approval is requested, authorize only the displayed token
For an ERC-20 token, the wallet may ask for an approval before the bridge deposit. Check the token symbol, spender, network, and amount in the wallet prompt. The approval transaction succeeding means only that the bridge can use the permitted token; it does not mean the transfer itself is complete.
After the quote passes your check, submit the deposit
Review the source chain, destination chain, input amount, expected output, recipient, and fee one final time. Then confirm the deposit transaction in your wallet. A successful origin-chain transaction hash is the proof that your deposit was submitted, not proof that the destination funds have arrived.
Once the deposit is confirmed, watch for the destination fill
Across uses relayers to fulfill the deposit on the destination chain. Keep the transaction hash or deposit identifier and check its status until it shows a completed fill. Do not submit the same transfer again merely because the destination balance has not refreshed.
For the live route, current quote, and transaction flow, open the Across bridge interface. It is the place to check the terms immediately before you sign.
If the destination balance changes, verify the receipt on-chain
Switch your wallet to the destination network and confirm the token balance or transaction receipt there. The transfer worked when the destination transaction is confirmed, the recipient address matches yours, and the received amount is consistent with the completed quote—not merely when the origin transaction says “success.”
If no fill arrives before the deadline, wait for the status outcome
An unfilled deposit can expire and be refunded rather than silently disappearing. Follow the deposit status and use only a refund address you control on the origin chain. A refund or completed destination fill is the final outcome to verify.
