Crypto deposits look simple from the outside: send coins, see balance. Underneath, the gateway has to watch several chains, verify a transaction actually landed, and credit exactly once.
A deposit address per chain
Pick a chain and an asset, and the gateway shows the deposit address and QR for that network. Addresses are chain-scoped on purpose — sending an asset on the wrong network is the single most common way to lose funds.
Verification and confirmations
The verifier reads the transaction from the chain itself: the recipient, the amount, the token contract, and the confirmation depth. Only when all four match the expected deposit does the credit happen.
- EVM chains verified through receipt and transfer logs
- Solana verified through the confirmed transaction record
- Idempotent crediting so a replayed transaction hash cannot double-credit
Tracking a deposit
Every deposit shows a status you can follow: detected, confirming, credited, or needs review. The transaction hash is linked, so you can always compare the wallet's view to the chain's view.
