Deposit Detection

Overview

Meaning and scope

Deposit detection is the process of identifying an incoming blockchain transaction or ledger credit that may represent a deposit to a monitored account or address. Detection can use nodes, indexers, webhooks, exchange APIs, logs, mempool observation, or ledger files and then progress through execution and confirmation checks.

Mechanism and operation

Deposit detection recognizes an incoming transfer or ledger credit that may be payable to a monitored account. Blockchain systems use nodes, event logs and indexers to observe transfers; providers may also send webhook notifications. Detection must validate the receiving address, chain, asset contract and transaction context before associating the event with a customer. Some networks provide mempool observations before block inclusion, whereas other transfers appear only after confirmation. A detected payment can later be invalidated by a reorganization or fail the merchant’s amount rules. A robust system records discovery separately from assignment, confirmation, balance credit and final reconciliation. Duplicate callbacks must not create duplicate deposits.

Practical payment example

A node detects an incoming transfer, but the accounting service does not credit the customer until the asset and amount are validated.

Operational checks

Retain the authoritative block or transaction reference, monitored destination, token identity, observed amount, detection time, confirmation status and deduplication key. Test delayed indexer and reorganization cases. Detection is not final credit; the transaction can be unconfirmed, failed, replaced, reorganized, unsupported, or unrelated to an active deposit instruction. The workflow for Deposit Detection commonly touches Deposit Mapping and Deposit Attribution. For Deposit Detection, an address-based payment workflow must bind the destination to an exact network, asset representation, account or invoice, custody source, and active period. The authoritative record for Deposit Detection should also show the rule version, responsible system, permitted state transition, and any downstream action such as fulfillment, settlement, refund, or manual review.

Distinctions and limits

Detection means the system observed a possible receipt; it does not prove beneficiary attribution, paid status or final settlement.
