What is Custom Fields?
Custom Fields explained for crypto payment merchants using Zateway.
Custom Fields is a key concept in crypto payments. With Zateway, merchants use non-custodial USDT and USDC checkout across Polygon, Solana, Base, BSC, Arbitrum, Optimism so Custom Fields connects directly to faster settlement, lower fees, and zero chargebacks.
Why Custom Fields Matters for Merchants
Understanding Custom Fields 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 Custom Fields
Zateway supports production and sandbox flows so you can test Custom Fields 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 Custom Fields knowledge with Zateway's 1% flat fee model for predictable unit economics.
