Contract
by DeFi Safety Oracle in Onchain & crypto
Contract-level risk scan for any EVM token: is the source verified, is it an upgradeable proxy and who is its admin, who owns it and has ownership been renounced, and which dangerous powers the bytecode exposes (mint, pause, blacklist, fee-setting). Returns the raw on-chain evidence, not just a score, so an agent can justify the decision it makes.
