Deposit received notification

Once the end-user sends funds from their wallet, transaction-specific events will be broadcasted on the blockchain. We listen for such blockchain events and will send them to you via an endpoint provided by you when creating your business through the dashboard.

Based on our instant deposit feature an event will be sent to you as soon as we see a new deposit transfer broadcasted on the designated wallet address. At this stage, the status of the transaction is still UNCONFIRMED We run an internal probabilistic algorithm to help us identify double spent attempts or illicit transactions. If we detect such a case we won't propagate this event to you systemically and will instead contact you about it. Note that only UTXO-based coins (BTC, LTC, BCH etc.) have such an event, whereas account-based coins (ETH, ERC20, XLM, XRP) don't.

If the deposit doesn't meet our instant deposit conditions a notification will be sent once the transaction is added in a block and there is 1 blockchain confirmation.

If our initial attempt to send a notification fails, we will retry sending it every 2 minutes for up to 24 hours. Once the notification is successfully delivered, all retries will stop. If unsuccessful after 24 hours, retry attempts will cease.

This callback notification is sent on your depositReceivedCallbackUrl endpoint.

The networks of some coins like XRP and XLM are extremely fast. It takes literally ~1 second to verify and confirm a transaction once it is broadcast on the network.

On average a Bitcoin transaction to be included in a block requires ~15 minutes. By using Monolo you'll be able to credit Bitcoin deposits in less than 10 seconds.
