Reconcile payments with on-chain data

1List transfers for the pay-to address

Fetch the on-chain transfer history for the invoice's pay-to address on its chain. Reads accept limit and offset so you can page deterministically.

curl https://api.1st-node.com/v1/data/tron/address/T.../transfers \
  -H "Authorization: Bearer sk_live_..."

2Match transfers to settled invoices

Join each inbound transfer to the invoice by pay-to address and amount. Confirmed deposits should reconcile one-to-one with settled webhooks.

> { "transfers": [
>   { "hash": "0x...", "to": "T...", "amount_usd": 49, "confirmations": 41 }
> ] }

3Flag mismatches

Any settled invoice with no matching transfer, or any inbound transfer with no invoice, is an exception to investigate. Because webhook delivery is idempotent, a duplicate event is never the cause of a double credit — the chain history is your independent check.
