One key becomes an address on each. ONE is a coin at your Sui address and USDC lives at your Ethereum one, so neither needs a key of its own.

What it can do

  • ProtectSeal a note so only one key can open it.
  • SignPut your name to anything. Anyone can check it.
  • Sign inSign in to ONE with the key itself.
  • SellSell pages, agents and skills. On Sui testnet today.
  • BuyCredits for AI models, coins, the marketplace.

Pay a name, not an address Testnet

An address is 42 characters and a public ledger.

You paste it, check the first four and the last four, and send a dollar to see if it arrives. Every address you publish tells the world what you hold, and each payment tells it who paid you. ONE changes three things. On Sui testnet, with test coins.

  • You pay a name. No address to paste.

  • Each payment lands at a fresh address only the person you paid can find.

  • The money arrives with a signed receipt that says who sent it, and they can check it.

24 words bring it all back

Write them on paper and a lost phone costs you nothing. A key made today opens in any standard wallet too.

Testnet

Pay a name

Type "Your Name", not 42 characters. Each payment lands at a fresh address only they can find. On Sui testnet today.

Live

Know who paid you

Payments sent through ONE carry a signed receipt: "Paid by Your Name, verified".

Testnet

Agents with a ceiling

Each agent spends from a vault on chain, inside a ceiling you set. Above it the chain refuses, whoever signs. On Sui testnet today.

Live

Your fingerprint decides

Above your limit, the agent asks. Your phone shows what, to whom, how much and why. Face ID or Touch ID approves exactly that.

For agents

An agent needs no account and no card

One call gives an agent a key and a group it owns, with the same verbs a person has. The key does not expire. Revoke or rotate it when you are done with it. Send a Sui address in the body and the wallet field comes back set; leave the body empty and it is null.

A person

Press Generate at the top of this page. Your device draws the key; nobody else sees it.

Generate → Keep → your addresses appear

An agent

Runs one command. The key is written to a file on its own machine, and the JSON lists its five addresses.

npx oneie key new --out key.json --yes-i-accept-plaintext-file --json

An account for it, with a group it owns, is one call:

curl -X POST https://one.ie/api/auth/agent \
  -H 'content-type: application/json' -d '{}'
# -> { "uid", "apiKey", "wallet", "group" }

The vault that holds an agent’s money runs on Sui testnet with test coins, and an agent is on the practice network by default. The ceiling is enforced by the chain, so above it the spend is refused whoever signs. On Sui testnet today.

How an agent pays, and when it asks you

  1. 01

    The agent proposes

    A payment, with a reason.

  2. 02

    Your rule decides

    Under your limit it pays. Over it, it asks.

  3. 03

    Your fingerprint approves

    Your phone shows exactly what, to whom, and how much.

  4. 04

    Paid, with a receipt

    Signed, and checked before the money moves.
