What is 3d Secure?
3d Secure explained for crypto payment merchants using Zateway.
3d Secure 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 3d Secure connects directly to faster settlement, lower fees, and zero chargebacks.
Why 3d Secure Matters for Merchants
Understanding 3d Secure 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 3d Secure
Zateway supports production and sandbox flows so you can test 3d Secure 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 3d Secure knowledge with Zateway's 1% flat fee model for predictable unit economics.
