ScriptMasterLabs releases free AI agent wallet with built-in payment refusal

ScriptMasterLabs has released the SML x402 Agent Wallet, a free and MIT-licensed tool designed to enhance security for AI agents handling payments. The wallet operates without fees and includes features like a spend leash, a pre-flight trust check for sellers, and integration with the Verdict Protocol for decision-making by a jury. It refuses payments if a seller's trust profile is flagged as untrustworthy or if the Verdict Protocol jury advises a wait, as demonstrated in live testing where payments were refused due to these checks. AI

IMPACT Enhances security for AI agents handling financial transactions by adding automated checks and refusal capabilities.
