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.
