Security & Audits

Circuit spent a full year focused exclusively on security before mainnet launch — 6 months of internal auditing where the team paused all feature development to hunt for exploits and vulnerabilities, followed by 6 months of external reviews through a triple-layer process: a private firm audit, an invite-only bug bounty, and a public audit competition. Over 20 confirmed issues were identified and fixed.

Why Chia's coinset model matters

Unlike EVM-based protocols where contracts hold shared mutable state, Chia's coinset model means each coin is an independent, immutable object that can only be spent once. There's no shared state to corrupt, no reentrancy attacks, and no storage slot collisions. Every state transition is explicit and atomic — making the protocol inherently more auditable and resistant to entire classes of vulnerabilities that plague EVM DeFi.

Cantina — Live Bug Bounty

Active since Nov 5, 2025

Live Up to $20K per finding

Ongoing security program covering core Chialisp smart contracts. 58 findings submitted so far. This is the hardening phase — low-hanging fruit was already picked during the pre-launch audits, so researchers are now probing for deeper, more complex exploits.

Critical: up to $20,000
High: up to $10,000
Medium: up to $2,000
