Satelink Documentation

Satelink is a DePIN RPC gateway on Polygon PoS. Developers and autonomous machines pay $0.00003 per call in USDT; node operators earn 50% of routed revenue; everything settles through an on-chain vault you can verify on Polygonscan. Start with the Quick Start — your first call takes under two minutes and needs no account.
