QR Wallet

  • Name: QR Wallet
  • URL: https://qr.xyz/
  • Category: smart-account wallet / sponsored-transactions wallet app / QR payments app
  • Tags: ethereum-ecosystem
  • Summary: QR Wallet is a small EVM wallet-and-payments bundle built around smart accounts, gas sponsorship, and QR checkout flows. There is no deep new protocol surface here. The note is mainly useful as a compact example of an operator-managed app bundling account abstraction, merchant integrations, and QR parsing into one consumer shell.
  • What it does:
    • Gives users a wallet experience with unified balances aggregated across 12 supported networks and multiple wallets inside one app
    • Uses smart accounts so funds live in a programmable account while an EOA signs operations, enabling gas abstraction and multi-action execution flows
    • Keeps the same smart-account address across supported EVM networks through CREATE2-style deployment semantics
    • Sponsors transaction fees through a paymaster flow on supported networks and falls back to stablecoin or native-token gas payments when sponsorship is unavailable
    • Supports QR-code-based crypto payments, including QR Wallet Pay, Gaian Pay integration, and Thai PromptPay QR parsing with crypto-funded settlement
    • Offers partner integrations for businesses that want to accept crypto payments via QR codes, receive webhooks, and support USDC or USDT across 12 blockchains
    • Packages those wallet and payment surfaces into one operator-managed app rather than exposing a thinner wallet-only product
  • Key claims:
    • The Smart Accounts page says a smart account is a personal smart contract wallet that can skip gas payments, execute multiple actions at once, and use the same address across Base, Arbitrum, Polygon, Optimism, and other EVM networks
    • The same page says QR Wallet uses audited Alchemy LightAccount contracts built on the ERC-4337 account-abstraction standard
    • The Sponsored Transactions page says QR Wallet pays gas via a paymaster, describes the UserOperation → bundler → EntryPoint flow, and lists sponsored support across networks such as Base, Arbitrum, Polygon, Optimism, BNB Chain, World Chain, HyperEVM, Monad, Plasma, and temporarily Ethereum
    • The Wallet & Balances page says the app aggregates balances across 12 supported networks and supports multi-wallet organization inside one interface
    • The QR Payments page says the wallet can process QR Wallet Pay, Gaian Pay, and Thai PromptPay-compatible QR flows while automatically detecting network, token, and amount
    • The Integration Overview says businesses can accept USDC and USDT payments via API, let buyers pay on whichever of 12 blockchains they prefer, receive instant confirmation on L2s, and use webhooks for automation
    • The docs make clear this is a packaged operator app, not just a wallet contract wrapper: merchant APIs, paymaster-backed UX, QR parsing, and partner-facing payment integrations all sit under one branded surface
    • The Partnership Request page shows QR is explicitly onboarding payment integrations, DApp listings, token integrations, quests, and strategic partnerships as part of one ecosystem surface
  • Whitepaper: No canonical standalone QR Wallet whitepaper or litepaper surfaced in this pass. The clearest current source of truth was the QR docs corpus, especially the smart-account, sponsored-transaction, wallet, payment, and partner-integration pages; see ../whitepapers/qr-wallet-primary-sources-2026-05-04.md.

Internal linkages

Control surface

  • Authority sits in sponsored-transaction policy, supported-network coverage, smart-account deployment defaults, QR parsing behavior, merchant-integration terms, and the hosted app infrastructure wrapped around those pieces.

  • Read it as a small operator-managed wallet shell, not as a new account-abstraction primitive.
