Soroban Contract State Management - CertiK

CertiK explores two critical vulnerabilities in Soroban contract state storage: storing long-term data in Temporary storage risks irreversible loss when entries expire; relying on TTL expiry alone for nonce validation enables signature replay attacks. The article walks through vulnerable code patterns and secure alternatives using Persistent and Instance storage.

PQ-Chain: Before the locks fail, build the fence!

Soundness Labs and Mysten Labs have developed PQ-Chain, a backward-compatible upgrade for EdDSA-based blockchains like Stellar, Solana, Sui, and Aptos that adds quantum resistance without hard forks or address changes. It leverages the existing quantum-secure seed in EdDSA keypairs, proven via PQ-NIZK proofs at the transaction and account levels. This opt-in approach provides immediate protection during the transition to native post-quantum signatures.
