Integration notes
What matters before production
Solana addresses are case-sensitive
BoltUtil preserves Base58 address casing and matches the exact destination account supplied by the order.
Finalized transfer data drives confirmation
The payment flow validates the SPL-USDT mint, destination, amount, signature, and finalized slot before matching an order.
Durable intake protects received events
Authenticated provider events are stored before acknowledgment and retried if internal processing is temporarily unavailable.
