KiroPay

  • Name: KiroPay
  • URL: https://kiropay.app/
  • Category: agentic payments infrastructure / multi-protocol payment middleware / account-abstraction treasury and policy control plane
  • Tags: ethereum-ecosystem
  • Summary: KiroPay is a routing-and-policy wrapper for agent payments. It bundles x402/MPP/fiat routing with ERC-4337 agent accounts, treasury handling, and spend controls. Useful operator stack, not a universal payment layer.
  • What it does:
    • Routes agent payments across x402, Machine Payment Protocol (MPP), and fiat rails through one integration surface
    • Provides ERC-4337 smart accounts for agents with multi-signature control, session keys, spending policies, social recovery, and gas-sponsorship support
    • Maintains a yield-bearing treasury for agent funds, with official materials naming USDC, USDT, and DAI plus Aave and Compound-style strategies
    • Enforces onchain enterprise controls through a policy registry with daily/monthly spending limits, token and target allowlists, and emergency-pause behavior
    • Ships a developer-facing implementation surface including smart contracts, a Python SDK, examples, docs, a public GitHub org, and a Sepolia testnet-facing product surface
    • Positions itself as infrastructure for autonomous API purchases and machine commerce rather than only as a human checkout product
  • Key claims:
    • The homepage calls KiroPay “The Universal Agent Paymaster” and says agents can transact autonomously across x402, MPP, and fiat rails through one unified middleware layer
    • The docs overview says KiroPay is purpose-built for the AI agent economy and is trying to resolve payment fragmentation by establishing a unified middleware layer across x402, MPP, and traditional fiat channels
    • The same docs say protocol selection is based on transaction size, counterparty capabilities, gas optimization, and settlement-speed needs, which is stronger evidence of routing middleware than of a single-rail wallet
    • The docs also frame KiroPay as combining neobank-style treasury management, DeFi yield optimization, and multi-protocol payment routing, which supports cataloging it as a broader operational stack
    • The GitHub README says the repository contains the core smart contracts, SDKs, and examples for building autonomous payment systems, and it lists KiroPayAgentAccount, KiroPayTreasury, KiroPayPolicyRegistry, TransactionRouter, and a Python SDK as implemented components
    • The README describes the agent account as ERC-4337-based with multi-sig, session keys, spending policies, and guardian recovery, which makes the wallet/governance layer a first-class part of the product rather than an implementation detail
    • The docs and README both present an official whitepaper and active-development posture, including a Sepolia testnet callout on the homepage and “Version 0.2.0 | Active Development” language in the repo README
  • Whitepaper: An official KiroPay whitepaper is linked from the docs and GitHub README and was saved locally as ../whitepapers/kiropay-whitepaper.pdf. The clearest current source of truth in this pass was the homepage, docs overview, repo README, and the linked whitepaper artifact; see ../whitepapers/kiropay-primary-sources-2026-05-02.md.
