@tang-vu tang-vu released this 18 Jun 01:29

verity — a reputation-staked x402 signal oracle and an autonomous DeFi agent that trusts it only as far as its on-chain track record. Built for the Casper Agentic Buildathon 2026 (Build Direction #2 — RWA oracle with verifiable on-chain reputation).

An oracle's word is worth exactly its on-chain accuracy. A DeFi agent discovers the oracle over MCP, pays per signal over x402 (settled on-chain by the Casper facilitator), weights its trade by the oracle's on-chain reputation, and swaps via the CSPR.trade MCP — no human in the loop.
