SecurityΒΆ
The MillionEther contract incorporates necessary security features listed in the official paper by ConsenSys, making it safe against known attacks, including Recursive call attack (DAO ATTACK). It has simple contract structure, no external calls and 100% tests coverage.
Following general philosophy of the same document The MillionEther contract is prepared for unknown attacks by incorporating failsafe measures (escape paths). If something goes wrong admin is allowed to pause/resume the contract, freeze/unfreeze users, issue refunds.
