UTN

UTN (Umbrella Trust Network) is a network your app calls over HTTPS. You do not run a node. You send JSON to an RPC URL, or you use UTN Wallet.

This site documents the public testnet. The coin here is T-RAIN. RAIN is the coin name reserved for mainnet. Mainnet is not published on this site. Chain id on this testnet: 20261003.

Gas paid with the coin is the only network revenue.
