sigloop
AI agents, web3, ERC-4337
sigloop is the payment layer the agentic web needs, providing AI agents with smart contract wallets featuring safety limitations, session keys, scoped permissions, and native HTTP 402 payment automation.
built on ERC-4337 account abstraction, sigloop lets developers give their agents secure, budget-controlled wallets without managing EntryPoints, UserOps, or bundler infrastructure.
sigloop was born from a simple realization: AI agents need to transact autonomously, but they should never have unchecked access to funds. we built the guardrails that make agent payments safe.
