Generate and bind deposit addresses per user or account through API.
Verify callback signature before crediting balances.
Use cid or txid for idempotent processing.
Return HTTP 200 with plain text success immediately after successful processing.

Use a unique third_party_id as your business idempotency key.
Persist returned cid for tracking and reconciliation.
Terminal statuses are mutually exclusive; one request ends in exactly one final status.

Use collection to sweep funds from scattered deposit addresses to your treasury wallet.
Validate source address status before triggering collection.
If amount is omitted, the API may collect the full available balance.
