Calcifer
 Senior Smart Contract Security Engineer | Solana Specialist | Web3 Auditor

Calcifer is a leading smart contract security engineer with a sharp focus on the Solana ecosystem and a proven track record in uncovering high-severity vulnerabilities across DeFi, NFT, and oracle-integrated protocols. With extensive experience in formal verification, fuzzing, static analysis, and Solana’s Anchor framework, he blends deep blockchain architecture knowledge with offensive security strategies to harden smart contract systems at scale.

At Can I Bet On, Calcifer led the development and security of a prediction market protocol powered by LMSR bonding curves, Metaplex-integrated NFTs, and secure oracle feeds, all optimized for Solana's parallelism and sub-second finality. His design efforts resulted in performant, low-slippage, and censorship-resistant market mechanics.

A consistent top performer in Web3 security competitions, Calcifer placed 2nd out of 248 in the Inclusive Monorepo contest and discovered 17 critical vulnerabilities, preventing multimillion-dollar exploits. His other accolades include ranking in the top 10 of multiple competitions (Code4rena, Sherlock) and identifying a critical signature replay bug in Crestal Network’s deployment logic.

Calcifer actively contributes to the Web3 security community through technical publications such as "How Secure Are NFTs?" and the popular "Python for Hackers" and "Linux for Hackers" series on Hacklido (100K+ reads). He also speaks at blockchain security events and contributes to auditing ecosystems like Cantina and Cyfrin.
