Why Finality Matters for Merchants
Understanding Finality helps you design safer checkout. Zateway keeps funds non-custodial — payments route to your wallet while you still get webhooks, payment links, and API control.
How Zateway Handles Finality
Zateway supports production and sandbox flows so you can test Finality safely. Use payment sessions, HMAC webhooks, and multi-chain USDT/USDC to operationalize this concept without holding customer funds.
Best Practices
Prefer stablecoins over volatile assets, verify webhook signatures, wait for sufficient confirmations, and keep private keys offline. Pair Finality knowledge with Zateway's 1% flat fee model for predictable unit economics.
