Crypto news: Wu Shuo learned that Solv Protocol stated that on July 13, a security incident occurred involving the BTC+ contract on BNB Smart Chain. The attacker upgraded the BTC+ minting proxy contract and minted unauthorized tokens due to a leaked deployer private key. The team isolated the malicious contract within 3 hours and froze, destroyed, or isolated all unauthorized BTC+; the underlying BTC assets were not affected. BTC+ subscriptions and redemptions have been temporarily paused, and redemptions are expected to resume within two weeks. Solv Protocol has rotated the relevant access credentials and signing keys, and has launched an external security audit; it will subsequently release a detailed incident report.
