After RFI and Safeheron launch their quantum digital asset pilot this week, participating institutions will test wallet generation and on-chain transfers on the NEAR testnet. Its signature layer uses the ML-DSA-65 specified in the NIST FIPS 204 standard and is integrated with a multiparty computation (MPC) process.
The technical focus of this test is not to prove that quantum computing can already break existing wallets. Instead, it verifies whether a wallet can switch its cryptographic algorithm without rebuilding the entire custodial infrastructure.
Conventional wallets typically bind the address, private key format, transaction encoding, and signature verification rules to the same elliptic-curve cryptography stack. After migrating to ML-DSA, the public key and signature sizes will increase significantly. Hardware security modules (HSMs), MPC nodes, transaction parsers, and on-chain verification logic all need to be updated in parallel. Simply replacing the signing function in the client is not enough to complete the migration.
MPC also does not automatically provide quantum security. What it addresses is the problem that the private key does not appear as a single complete point. If the parties still jointly execute a traditional signature algorithm, the underlying mathematical assumptions do not change.
This pilot incorporates post-quantum signatures directly into the distributed key generation and signing workflow. It tests the full key lifecycle, including key generation, share storage, joint signing, and on-chain verification.
Post-quantum wallets need to have “cryptographic agility”: accounts can upgrade the signature scheme, old assets can be migrated, new and old algorithms can coexist during the transition period, and recovery and auditing processes remain effective.
The real engineering challenge is not generating a new key, but securely updating the keys across the entire authorization chain.
