Stellar’s Bell upgrade went live on testnet ahead of a mainnet validator vote, requiring wallets and indexers to update their software. The release adds optional post-quantum signature verification for smart contracts on the Stellar network. The change matters because it lets developers adopt quantum-resistant signing without forcing every contract or integration to migrate at once. Watch the mainnet vote and whether wallets, indexers and Soroban developers ship compatible updates before activation.
