Kipurse（启付）

A self-custodial USDC wallet on Base that lets AI agents pay within limits you set, with Face ID approval on your iPhone. 一个在 Base 上的自托管 USDC 钱包：AI 只能在你设定的额度内付款，超额、新收款人都要你在 iPhone 上用 Face ID 批准。

Layout

  • ios/ — iOS app (SwiftUI), widget, KipurseCore Swift package, unit and UI tests.
  • server/ — Kipurse production gateway (cleaned copy): owner API, AI agent MCP (OAuth), Siri endpoint, pause, caps, onboarding sponsor caps, rescue (offline withdraw) page, SDK. Operator values (addresses, keys, URLs) come from config outside the repo.
  • contracts/ — Solidity V5 contracts (trust, adapter, phone approver, vaults) with Foundry tests; install-deps.sh fetches pinned libs.
  • docs/compliance/ — compliance notes (not legal advice).

Principles

  • Self-custody only: keys stay in the iPhone Secure Enclave / the user's own smart wallet. No pooled custody.
  • One wallet per person. The owner can always withdraw everything, even if the Kipurse server is down.
  • Hard AI caps (default 20 payments/day, $2/day, $0.25 per payment). One "Pause AI payments" switch stops every AI, including Siri.
  • Identity: Coinbase Verified attestation only. Funding: Coinbase / Coinbase Onramp only. Fees are in USDC, paid from the wallet.

Build (iOS, simulator)

cd ios
cp Config/Local.xcconfig.example Config/Local.xcconfig   # optional; fill in your own team / bundle prefix
brew install xcodegen && xcodegen generate                # if the project needs regenerating
xcodebuild -project Kipurse.xcodeproj -scheme Kipurse -destination 'platform=iOS Simulator,name=iPhone 17' build
swift test            # KipurseCore unit tests

Server

cd server && npm ci && npm test

Operator config lives OUTSIDE the repo (see server/kit/operator.mjs); KIPURSE_DEMO=1 runs unbranded. Configuration comes from environment variables; see examples/ and DEVELOPMENT_SETUP.md. Never commit .env files or keys.
