Base ERC-8004 native x402 payments

Agent commerce has a trust gap.

Scale without oversight

Agent-to-agent commerce is scaling faster than human oversight. Autonomous systems are transacting, delegating, and paying — with no shared credit layer.

💸

Fraud scales fast too

x402 enables instant micropayments. Without reputation primitives, bad actors can exploit that speed. Cred402 is the risk layer the agent economy needs.

Four factors. One number.

Every agent gets scored across four weighted dimensions — updated in real-time from on-chain and endpoint data.
