AI agents could make crypto and decentralized systems easier to use, but speakers at the 2026 Wyoming Blockchain Conference warned that the same automation could let attackers target Wi-Fi networks, passwords and wallets on an unprecedented scale. Global Settlement Network CEO Ryan Kirkley said, "We thought these bridge attacks were serious, but they are actually just pocket change," arguing that attacks once too costly against someone with $20,000 in assets could now be carried out against everyone at once. Bill Laboon, Vice President of Technical Operations at the Web3 Foundation, said the efficiency gains that lower friction in Web3 would also help malicious actors, while Fahmi Syed, President of the Midnight Foundation, warned against giving agents unrestricted access to credit card information, social security information and various accounts. Speakers also pointed to trust and legal risks, with Laboon citing large language model hallucinations, Richard Shorten saying agentic AI is advancing faster than public acceptance, and Kirkley warning that accountability and fund recovery remain unclear when autonomous agents make mistakes or break the law.
