Never miss a deposit.

Deposit webhooks for teams that move money. We scan every block, track confirmations and reorgs, and keep delivering until your server says it got the event.

Early access opens in batches. We'll email you when yours does.

Block scanning, not address polling

We read each block once and match it against every address you watch. A hundred addresses or a hundred thousand, the latency is the same.

Replay from any cursor

Every event has a stable ID and a cursor. If your server was down for an hour, resume from last_cursor and get everything you missed.

One lifecycle on every chain

seen → confirmed → reverted. Amounts arrive in token units, with confirmation depth set per chain.
