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