Wpayin Wallet 1.1.9

Wpayin Wallet is a non-custodial iOS wallet built with SwiftUI and Trust Wallet Core. It supports Bitcoin, Ethereum, Solana, EVM-compatible networks, tokens, network-aware transaction history, NFTs, DEX swaps, cross-chain bridging, and atomic EVM P2P trading.

This project has not received a professional security audit. Use test accounts and small amounts only. You are responsible for protecting your recovery phrase and private keys.

Version 1.1.9

• Redesigned Deposit, Withdraw, asset details, Swap, Bridge, and multi-network transaction history for clearer network-aware wallet flows.
• Added Request Payment QR/links and optional WalletConnect support with explicit proposal, signature, and transaction review.
• Added fee-aware Max calculations, route/status tracking, Face ID protection for transaction signing, and selectable time zones.
• Added custom-token discovery and removal controls, P2P improvements, and a disclosed application-development fee for supported outgoing operations.
• Added NFT spam protection with provider filtering, conservative local detection, a reviewable hidden folder, and manual hide/restore controls.
• Expanded the in-app Help Center and added a selectable version history under About, covering releases 1.1.0 through 1.1.9.
• Refined and slightly extended the launch experience without restoring the previous dark backing behind the logo.

See RELEASE_NOTES_v1.1.9.md for the complete release notes.

Requirements

• macOS with Xcode 16 or newer
• iOS 15.0 or newer
• An Apple development team for installation on a physical device

Build and run

git clone https://github.com/Lakylife/wpayin-erc20-ios-app.git
cd wpayin-erc20-ios-app
open Wpayin_Wallet.xcodeproj

Xcode resolves the pinned Swift Package Manager dependencies automatically. Select the Wpayin_Wallet scheme, choose an iPhone simulator, and press Cmd-R.

The command-line equivalent is:

xcodebuild \
  -project Wpayin_Wallet.xcodeproj \
  -scheme Wpayin_Wallet \
  -destination 'generic/platform=iOS Simulator' \
  CODE_SIGNING_ALLOWED=NO \
  build

No configuration file needs to be copied or created. Public RPC endpoints and keyless services provide the base wallet functionality.

Optional API integrations

NFT discovery and indexed transaction history use optional third-party API keys. In Xcode, open Product → Scheme → Edit Scheme → Run → Arguments and add the required values under Environment Variables:

Variable	Purpose
ALCHEMY_API_KEY	Ethereum NFT discovery
ETHERSCAN_API_KEY	Indexed EVM transaction history
COINGECKO_API_KEY	Optional authenticated CoinGecko access
P2P_BOARD_URL	Optional public P2P board endpoint
P2P_BOARD_ANON_KEY	Optional public P2P board client key
PLATFORM_FEE_RECIPIENT	Optional EVM platform-fee treasury address

The app still builds and runs when these values are absent. Missing provider keys disable only their corresponding optional data. Do not add credentials, treasury addresses, or environment files to source control. Any value supplied to an iOS application at runtime can still be extracted, so production deployments should use restricted keys or a server-side proxy.

Optional public P2P offer board

P2P offers can be public (discoverable by every app user) or private (shared only by QR/code). The optional public board uses a separately configured Supabase/PostgREST deployment; setup is documented in docs/P2P_OFFER_BOARD.md. Private QR/code trading continues to work when the board is not configured.

Supported networks

• Bitcoin (Native SegWit/BIP84)
• Ethereum
• Solana
• BNB Chain
• Polygon
• Arbitrum
• Optimism
• Avalanche C-Chain
• Base

Cross-chain bridging is available between the supported EVM networks listed above through LI.FI. Native Bitcoin and Solana cannot participate in atomic EVM P2P settlement; supported wrapped representations include WBTC, cbBTC, BTCB, and BTC.b where available.

Security

• Recovery phrases and private keys are stored in the iOS Keychain with kSecAttrAccessibleWhenUnlockedThisDeviceOnly.
• App lock supports Face ID, Touch ID, and device-passcode fallback.
• Sensitive wallet data must never be committed, logged, or included in screenshots.
• Review SECURITY.md before using or modifying transaction and key-management code.

To report a vulnerability, use a private GitHub security advisory rather than a public issue.
