Is your favorite cryptocurrency quantum ready? The new trend among crypto developers

The cryptocurrency industry is facing a growing imperative to prepare for post-quantum cryptography (PQC) threats, with organizations like NIST urging immediate migration away from quantum-vulnerable algorithms by 2035. Coinbase's advisory board highlights that blockchains, wallet providers, exchanges, and custodians must proactively address this, as current uncertainties are already impacting investment. Google has set an internal PQC migration timeline for 2029. The migration challenge is complex, spanning consensus and execution layers, wallets, exchanges, custodians, key management, and hardware, with hardware-based solutions and MPC support requiring significant updates. Crypto-agility, defined as the ability to adapt algorithms across all systems, is crucial. While some blockchains like Ethereum's Layer-2s (Optimism, Arbitrum, Base) and Algorand have announced PQC plans, Bitcoin's core developers largely maintain a wait-and-see approach, contributing to market uncertainty. Commercial entities like Trezor and AWS are already offering quantum-ready products and services, signaling that reputational sorting based on PQC readiness has begun. Demonstrating end-to-end PQC migration plans is becoming a trust badge, differentiating mature projects from those with vague claims and fostering institutional confidence.
