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