UTN

Umbrella Trust Network

A permissioned network for organizations.

Membership, a shared vault, and a record of what the organization is responsible for. The network is open to build on now. Mainnet is around the corner.

Overview

What UTN is

One network for the organization, the standards it runs, the coin it settles in, and the products built on top.

  1. 01

    Organizations

    Members, roles, invites, and a vault with monthly limits. The organization is who acts. People keep their own keys.

  2. 02

    UMBRO

    One library, @utn/umbro. Immutable contracts for the vault and the passport. A preset writes a profile once.

  3. 03

    RAIN

    The native coin. On the live network the unit is T-RAIN, so teams can build before mainnet. RAIN is the name that travels with mainnet.

  4. 04

    Apps

    Battery passports are the first product profile, on the same contracts. The next organization you bring uses that path.

Product

Wallet, Scan, and the standards behind them.

Open a passkey account, read the network, and ship against contracts you can verify.

Wallet

Passkey accounts. Send, sign, and pay from an organization vault. Gas for organization calls can be sponsored, then refunded from the vault.

Network

Live now. Mainnet next.

Start on the network that is already running. The mainnet coin and the public address will be named here when they open — not before.

Live

Testnet

Open today. Chain 20261003. The unit is T-RAIN, so you can deploy, sign, and read blocks before mainnet. Wallet, Scan, the faucet, and the RPC are ready.

  • Passkey wallet
  • Scan, with verified source
  • Faucet and public RPC

Soon

Mainnet

Around the corner. The coin is RAIN. The standards and the wallet stay. There is no mainnet address to add today. When the network opens, it will be published on this page.

  • Same organization model
  • Same UMBRO contracts
  • RAIN, named when it is public
Build ahead of it

Built to be checked

  • Read it on Scan Contract source can be verified. The transactions are on the network, not in a private log.
  • Nothing silent upgrades Contracts are immutable. A replacement is a new deployment, not a switch flipped in the dark.
  • On the way to mainnet Passkeys stay on the device. An outside review is part of opening mainnet.

Developers

For builders

Docs, the standards library, the package, and coins to deploy with. Enough to put an organization on the network this week.

Invite

Build on UTN.

Open a wallet, read the network, and put an organization on it. Mainnet is the next step, and the work you do now is the work that carries.
