What is Phantom Wallet?​

Phantom is one of the most popular Solana wallets, known for its user-friendly interface, security features, and multi-chain support. It's available as a browser extension and mobile app for iOS and Android.

Important: Non-Custodial Nature of reply.cash​

reply.cash is a non-custodial platform:

  • ✅ We do NOT custody your assets - Your funds always remain in your wallet
  • ✅ We facilitate top-ups and payments - We connect you to third-party services
  • ✅ Merchant rails handle conversion - Local payment providers convert USDC to local currency
  • ✅ You control your keys - Only you can sign transactions
  • ✅ Every transaction requires your signature - No automatic transfers without your approval

How it works:

  1. You connect your wallet (Phantom) to reply.cash
  2. You sign transactions to approve payments
  3. reply.cash facilitates the connection to local payment rails
  4. Merchant rails handle the actual conversion to local currency (KES, NGN, etc.)
  5. Your funds are never held by reply.cash - they move directly from your wallet to the recipient

Key Features:

  • ✅ Native Solana support (primary blockchain)
  • ✅ Multi-chain support (Solana, Ethereum, Polygon)
  • ✅ Built-in token swap functionality
  • ✅ NFT gallery and management
  • ✅ Staking capabilities
  • ✅ Browser extension and mobile app (iOS, Android)
  • ✅ Hardware wallet support (Ledger)
  • ✅ User-friendly interface

Supported Chains:

  • Solana (primary, native support)
  • Ethereum (EVM chain support)
  • Polygon (EVM chain support)

  4. Click "Approve" or "Confirm" to sign the transaction
  5. Transaction is sent to Solana network

Mobile (iOS/Android):

  1. Transaction request appears in Phantom app
  2. Review transaction details
  3. Use biometric authentication (fingerprint/face ID) or enter password
  4. Tap "Approve" or "Confirm" to sign

Signature Methods​

Phantom supports multiple signature methods:

  • Password: Enter wallet password to sign
  • Biometric: Use fingerprint (Touch ID) or face recognition (Face ID)
  • Hardware Wallet: If using Ledger, confirm on device

Note: The specific signing method depends on your Phantom wallet settings and device capabilities. reply.cash does not control how you sign - that's entirely up to your wallet.
