How scoring works →Summary
Grand Base was a decentralized real-world asset (RWA) synthetic trading protocol launched on Coinbase's Base layer-2 blockchain in early 2024. On April 15, 2024, the protocol suffered a critical security incident in which its deployer wallet was compromised, allowing an attacker to mint approximately 32.5 million unauthorized GB tokens and drain roughly $2 million in liquidity. The GB token subsequently lost over 99% of its value; no verified recovery or compensation plan has been confirmed, and the project's long-term operational status remains uncertain.
