AI Agent Wallet Offboarding Requires More Than Signer Removal

Summary

NightFall Technologies presents a checklist for removing an AI agent, bot, employee, contractor, or automation account from a crypto treasury or smart account. Its central warning is that deleting an address from the owner or signer list does not prove that all authority paths have disappeared. The checklist first requires verifying live owner membership, then inspecting enabled modules that may grant separate control. It also calls for checking delegated spending mechanisms, including Safe Allowance Module delegates and token limits, and reviewing ERC-20 allowances plus ERC-721 and ERC-1155 operator approvals. Unknown modules, unavailable RPC state, or unidentified delegation mechanisms should be recorded as unable to verify rather than treated as a successful check. The process should preserve the treasury, subject, chain, contracts examined, observed state, block context, and final verdict as evidence. NightFall says its Crypto Access Exit Check automates supported read-only checks for Safe owners, modules, allowance delegates and limits, and token approvals. The tool does not request private keys, sign transactions, or move funds, and the page offers a verified exit report for $49.
