About Polygon and Tether
Polygon (POL) launched in 2019 — Ethereum scaling, secured by Proof of Stake. There is no fixed maximum supply of POL. For POL deposits we wait for 30 confirmation(s) on Polygon PoS, which usually takes about 1 min.
Tether (USDT) launched in 2014 — Stablecoin, secured by Token on another chain. There is no fixed maximum supply of USDT. For USDT deposits we wait for 20 confirmation(s) on TRC-20, which usually takes about 1 min.
Swapping POL to USDT on noaml does not require an account. We quote the rate from multiple liquidity sources, include our 0.25% fee, and send the USDT directly to the address you provide. The minimum order is around $200 in POL; there is no fixed maximum for manual orders.
USDT exists on several blockchains. We send and receive USDT on TRON (TRC-20) by default — check which network your wallet uses in our guide USDT TRC-20 vs ERC-20.
