ChainCatcher reports that NEAR Protocol has posted on X that its team is adding post-quantum cryptography support to the network. Unlike Bitcoin and Ethereum, NEAR’s account model decouples accounts from cryptography, controlling access through rotatable keys. The NEAR One team is integrating the NIST-approved lattice-based FIPS-204 signature scheme as the first post-quantum signature option. Once live, any NEAR account holder will be able to rotate their keys with a single transaction to achieve quantum security. NEAR is also collaborating with software and hardware wallet providers to advance post-quantum support. Through its chain-signature functionality, NEAR can provide threshold signatures for over 35 chains; the NEAR Intents team is developing a quantum-safe cross-chain signature solution, offering a quantum-secure environment if other chains lag in adopting post-quantum cryptography. Evolution is also underway for consensus mechanisms, validators, block synchronization, and transaction signing—all aiming toward a single, future-compatible migration.
NEAR Protocol Adds Post-Quantum Cryptography Support for Quantum-Secure Key Rotation

Summary
NEAR Protocol introduces a protocol update with post-quantum cryptography support, enabling key rotation in a single transaction. The NEAR One team is integrating the NIST-approved lattice-based FIPS-204 signature scheme as the first post-quantum option. NEAR’s account model separates accounts from cryptography and uses rotatable access keys for control. The team is collaborating with software and hardware wallets to expand post-quantum support. NEAR Intents is developing quantum-safe cross-chain signature schemes to maintain security if other chains lag behind. The project is also aligning consensus, validators, block synchronization, and transaction signing for future readiness. This protocol update positions NEAR ahead of Ethereum’s recent announcements regarding quantum threats.
