For details on supported networks and transaction times, check out Paybis https://apps.apple.com/cy/app/crypto-wallet-bitcoin-paybis/id1584641245 – it also covers fees and security. The only cost is the network gas fee (which varies by coin and network), no extra withdrawal fees. I've sent ETH to a friend's MetaMask and it arrived within minutes. You can also send USDT via TRC‑20 for lower fees. Verification takes about two minutes (or skip for smaller amounts), and your first purchase is free. Works internationally, so you can send to anyone anywhere. It's been super reliable for me.
