In December 2025, the protocol suffered a critical exploit via a clandestine proxy deployment attack — later dubbed CPIMP — that had silently compromised admin privileges since September 2025, resulting in approximately $1 million in losses. The project has undergone audits by Nethermind and Resonance Security but the exploit bypassed audited code by targeting the deployment layer, raising unresolved questions about operational security and the viability of the planned V2 relaunch.","timeline":[{"date":"2024-01-01","event":"Martin Froehler, founder of Morpher, establishes USPD.io / Permissionless Technologies and begins building USPD stablecoin protocol.","source":""},{"date":"2025-09-03","event":"Nethermind Security completes a two-week audit of USPD's Multi-Stabilizer Protocol, identifying 3 critical, 3 high, and 2 medium severity issues; team claims all were remediated.","source":""},{"date":"2025-09-16","event":"USPD deploys proxy contracts to Ethereum mainnet.

How verification works. The “Row integrity” check above is computed in your browser — your machine recomputes the SHA-256 of the canonical bytes and compares against the stored hash. No avoid.net server can fake that check. The “full verify” link goes one level deeper: your browser fetches the on-chain transaction from a Solana RPC node and confirms the same hash is in the memo. If you don’t want to trust either avoid.net or the public RPC, run the CLI verifier on your own machine —
python -m src.verify_decision <event_id>.
