Maturing your smart contracts beyond private key riskPrivate key compromise accounted for 43.8% of crypto hacks in 2024, yet traditional smart contract audits rarely address architectural access control weaknesses. This post introduces a four-level maturity framework for designing protocols that can tolerate key compromise, progressing from single EOA control to radical immutability, with practical examples demonstrating multisigs, timelocks, and the principle of least privilege.

The Engineer’s Guide to Blockchain FinalityMany security-critical off-chain applications use a simple block delay to determine finality: the point at which a transaction becomes immutable in a blockchain’s ledger (and is impossible to “undo” without extreme economic cost). But this is inadequate for most networks, and can become a single point of failure for the centralized exchanges, […]
