Bridging between networks

How money moves between Senddy and the other networks you use.

Overview#

Your Senddy balance is private and lives on Base. You can bring money in from, and send it out to, eleven networks. Senddy handles the bridge for you: there is nothing to approve on the other network beyond sending, and nothing to claim on arrival.

Depositing from another network#

1. Tap Deposit, then Stablecoin Deposit
2. Under Send from, choose the network your money is on
3. Send USDC (USDG on Robinhood Chain) to the address shown, from any wallet or exchange

It usually arrives within a minute and goes straight into your private balance. The address is yours to reuse: every deposit to it lands in your balance.

• From Hyperliquid: use Hyperliquid's Send, not Withdraw. This route carries a flat bridge fee of about $1, so send at least $20.
• From Lighter: Lighter can't send to a deposit address. Withdraw from Lighter to your own wallet first, then deposit from that wallet.

Withdrawing to another network#

1. Tap Send and paste the recipient's address
2. For a 0x address, choose the network it's on. A Solana address is recognized automatically
3. Review and confirm

Senddy withdraws from your private balance and the bridge delivers it, usually within a minute. A Lighter withdrawal goes to the Lighter account owned by the address you paste, which must already exist.

How the bridge works#

Senddy bridges through Relay. Each transfer goes to a deposit address Relay makes for that route, and Relay's solvers deliver the funds on the other side. If a withdrawal can't be filled, it's refunded to a one-time address of yours and goes back into your private balance automatically.

Fees and timing#

Senddy's own fee per operation is in Pricing. When you deposit from another network, the network fee for sending from your wallet is paid by your wallet, as with any transfer.
