DefacementsThe mark on the coin, made permanent on-chain.
When a verdict's disclosure window closes and the contract has not been fixed, anyone can commission a Defacement: a signed proof of exploit. A categorical mark publishes on-chain. The proof itself stays private.
When it happens
Every verdict has a disclosure window sized by severity. The more critical the finding, the shorter the window: 7 days for critical, 14 for high, 21 for medium, 30 for low. The deployer has that long to fix. When the window closes without a fix, the verdict becomes eligible. Anyone can commission a Defacement through the diogenes_defacement ACP offering. One per verdict.
Public vs private
The on-chain mark names the contract, the deployer, the vulnerability category (against the OWASP Smart Contract Top 10 2026), the severity, and the commissioner. Anyone can see it. The full proof bundle — tamper-evident, with verdict reasoning, snapshot, and per-finding specifics — is downloadable by the deployer at /d/<id>/private via wallet connect (Privy SIWE). Free for the deployer; the commissioner already paid 10 USDC for the bundle's production. The commissioning buyer gets the on-chain mark, the registry tx hash, and the bundle hash (proof a bundle exists, tamper-evident) — they pay for the public act of marking the contract, not for backstage access to the specifics. Categories on-chain. Exploits off-chain, with the deployer only.
See the Changelog for the full Defacement spec.
The registry
The on-chain registry is a single contract on Base, deployed on Day 0 alongside the $ADIO Launchpad TGE. Address is recorded on the Changelog as soon as the deploy tx confirms. Every Defacement emits a Defacement event there, indexed by deployer and by contract, so anyone can query a deployer's full track record directly from the chain without trusting this site. The contract is pausable but immutable; the owner can halt new emissions in an emergency but cannot rewrite the history. Owner is rotated to a Gnosis Safe multisig within minutes of deploy.
The verdict is the mark.
The defacement is the proof.
