Truly non-custodial
Addresses derive from your xpub. The private key never reaches us, so we cannot touch the money.
xpub / BIP32 / EVM / TRON / BitcoinHow a deposit gets seen.
Reorg-safe cursors and configurable confirmation thresholds turn a raw transfer into a signed, screened event.
01
Detect
A monitored address receives a transfer. We catch it the moment it lands in a block.
deposit.detected02
Screen
The counterparty is checked against the OFAC SDN seed and your blocklist, with a 0 to 100 risk score.
screening: clear03
Confirm
We count confirmations to your per-chain threshold, surviving reorgs through persistent cursors.
20 / 20 confirmations04
Notify
A signed webhook fires, backed by retries and a dead-letter queue, alongside a real-time SSE stream.
deposit.confirmedThe payload is signed.
HMAC-SHA256 verified. Retries with a dead-letter queue. Replay any event.

We read the chain.
We never hold your keys.
Deposit addresses derive from your extended public key only. The private key never leaves your infrastructure. ArgusPulse cannot move, hold, or freeze your funds.
