Q402: Unifying Web3 Transactions
The Problem
On-chain execution today is fragmented—requiring multiple steps for authorization, allowances, and gas. This slows down autonomous agent economies.
The Solution
Q402 by @QTalk is the production-ready implementation of the x402 standard, delivering a universal delegated execution fabric.
Architecture
- Single-Signature Flow: Collapses multi-step transactions into one atomic Sign-to-Pay event.
- Signature Layer (EIP-712): Binds user or agent intent offline with cryptographic assurance.
- Delegated Execution (EIP-7702): Facilitator Network sponsors gas and submits transactions seamlessly.
Core Capabilities
- Works universally with ERC-20 tokens—no upgrades or pre-approvals.
- Built-in policy hooks for whitelists, limits, and expirations.
- Full audit traceability: every signed intent maps to an on-chain hash.
Impact
Q402 transforms decentralized systems from soft commitments into automated, enforceable execution. By binding payments and governance atomically, it eliminates human friction and key-loss risks—unlocking AI agents as true economic actors
