Built on Yellow Network

AI Agents with
Spending Limits

Give your AI agents the power to transact on-chain, controlled by smart-contract policies and executed gaslessly through state channels.

Core Features

Everything your agents need

Natural Language Commands

Type plain English like 'Swap 50 USDC for ETH' and Brian AI interprets it into executable Web3 transactions.

PolicyVault Controls

Smart-contract enforced daily limits, per-transaction caps, and protocol whitelists. Agents can only spend what you allow.

Gasless via Yellow Network

Transactions execute through state channels with zero gas fees. Save $0.12-$0.65 per operation compared to on-chain.

Multi-Agent Management

Authorize multiple AI agents with individual policies. Pause, resume, or revoke any agent in real time.

Live Command Feed

Terminal-style UI shows every command as it flows through interpretation, validation, and execution.

Emergency Controls

One-click emergency pause freezes all agents instantly. Emergency withdraw pulls all funds back to your wallet.

Architecture

How it works

01

Interpret

User types a natural language command. Brian AI parses it into a structured Web3 transaction.

02

Validate

PolicyVault smart contract checks: Is the agent authorized? Does the amount fit within daily and per-tx limits?

03

Execute

Approved transactions are routed through Yellow Network state channels for gasless, instant execution.

04

Settle

State channel operations are batched and settled on-chain, saving 99% on gas while maintaining security.
