On a Tuesday announcement, the Solana Foundation said it is working with post‑quantum security firm Project Eleven to prototype quantum‑resistant digital signatures on a dedicated Solana testnet. The pilot follows a full quantum threat assessment and claims to show that end‑to‑end quantum‑secure transactions can operate at scale, amid wider debate on when quantum computers may threaten existing cryptography. The initiative comes as NIST has endorsed several post‑quantum standards and industry figures, including Vitalik Buterin and Adam Back, offer differing timelines for when major networks like Bitcoin and Ethereum must migrate to quantum‑resistant schemes.

Ripple Payments has entered a partnership with Swiss crypto bank Amina to connect its fiat-to-stablecoin payment infrastructure to the FINMA-regulated lender. The collaboration, which follows Amina's integration of Ripple USD (RLUSD) in July, aims to make cross-border stablecoin transactions faster and cheaper while strengthening Ripple's presence in Europe.
