Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.
