Deposit addresses let users bridge without connecting a wallet. Instead of initiating a bridge from a connected wallet, users send funds to a designated address provided by Bungee, and Bungee routes funds to the destination chain and delivers tokens to the user’s wallet after processing. This makes it easy to onboard users to a new chain or fund a destination wallet from sources like CEX withdrawals or fiat on-ramps.Once generated, a deposit address expires after 10 minutes and is valid for only a single deposit transaction.This flow is useful when you want:
A direct transfer flow from the source wallet
To support flows where wallet connection is unavailable or intentionally skipped
To onboard users onto a new chain with a single, simple “send to this address” step
Depositing funds
The deposit transaction requires no calldata. You simply send the agreed amount to the deposit address returned by the API. As long as the amount covers the costs, it will be automatically bridged according to the route from the original quote.
Gas and fee considerations
For low-value transfers, the gas costs overhead can be significant, so we generally do not recommend deposit addresses for low-value bridging.
Post-deposit quote recalculation
After a deposit is detected, the quote is re-generated to account for gas price fluctuations and to recompute all fees. This means the final received amount may differ from the initial quote, but it will always respect the minimum amount specified.
If the minimum amount cannot be achieved, the deposit amount is refunded on the origin chain.
Refund behavior
Failures via deposit addresses are extremely rare, but still possible. By default, Bungee will automatically refund the funds on the origin chain to the refundAddress in your quote request. Any filling failure will then refund to this address.
