.x3

Understand it, try it, inspect the proof, and get the code. An agent can propose a payment. The owner's .x3 policy decides whether Guard authorizes the deposit address.

What .x3 does

One policy. The compiler checks it. Guard checks it again. The model does not get a vote.

.x3 protocol mark

The owner writes the rule

A mandate names the agent, the asset, the caps, the recipient, slippage, fees, and when the owner must approve.

The agent writes a program

The payment is another .x3 file. If it pays the wrong account, drops the nonce, or breaks a cap, it does not compile or Guard refuses it.

Settlement is labeled

The published trade is testnet: 1 test USDC from Base Sepolia to NEAR. Official 1Click quotes were checked and stopped before a deposit.

How a decision moves

The program names Base, Solana, or NEAR. Guard allows the deposit or it refuses. Base and Solana bridge. NEAR does not.

Invest from Base, Solana, or NEAR

Choose Base, Solana, or NEAR. The .x3 program switches to that asset, and the log lands on the rail you picked.

Raised $0 / Goal $100,000,000,000 · 0%

Same path as the software. Base and Solana bridge through NearIntents. NEAR is already there, so that program has no bridge. Guard checks the terms either way. This page only records the mark. It does not move funds.

    from Base.USDC amount 1000000000 receiver YOUR_BASE_ADDRESS

Stored only in this browser. The published Base trade is 1 test USDC on Base Sepolia. Solana uses the repo’s canonical example. NEAR uses the mandate that already allows Near.USDC, with no bridge. None of these marks is a finalized investment.

One demonstration, three tracks

AI Security & Defense

Recipient and asset allowlists, caps, slippage, fees, expiry, one-use nonces. Compiler off-chain. x3-guard on NEAR testnet.

Agent Economy

Permitted, approval-required, and denied payments. Testnet shows one allowed intent and one refused intent.

Unstoppable DeFi

One .x3 program, hash bound before the source transfer, then finalized on Base Sepolia and NEAR testnet through a trusted relay.

.x3 on NEAR

A NEP-141 community token. Fastest launch is a factory or Smithii Token Creator — one signature, full supply to treasury, then distribute against verified mainnet trades.
