Fireblocks has assisted smart contract wallet UniPass in addressing an account abstraction vulnerability in the Ethereum ecosystem. The vulnerability, found in hundreds of mainnet wallets, could have allowed attackers to take over UniPass Wallets and drain their funds. Fireblocks’ research team carried out a white hat operation to patch the vulnerabilities and mitigate the issue. Ethereum co-founder Vitalik Buterin has previously highlighted challenges in implementing account abstraction functionality.
