SafeWallet Pay

A secure Mantle-based P2P payment platform with escrow, refunds (including wrong-address sends), and bulk transaction management.
Built on Mantle Sepolia testnet (5003) with Web3Auth onboarding and a modern React UI.

📋 Problem Statement

Traditional crypto payments have critical issues, especially for everyday users and businesses in :

• No protection for wrong-address transfers

  • If you paste or type the wrong wallet address, the funds are gone forever.

  • There is no native “undo” or refund option once a transaction is broadcast.

• No escrow / claim process

  • Funds are sent directly to the recipient with no “claim step”, making disputes and trust hard to manage.

• No sender-controlled refunds

  • Even if the recipient never uses or even sees the funds, the sender has no way to pull them back.

• Inefficient bulk payouts

  • Paying salaries, vendors, community members or grant recipients needs many on-chain transactions, increasing cost and complexity.

• Complex onboarding & UX

  • Seed phrases, network configuration, and raw hex addresses are intimidating for new users.

• Infrastructure gaps

  • Many users need low-fee, fast, programmable payments for micro‑transactions, remittances, and bulk payouts, but don't get that from traditional rails.

💡 Our Solution

SafeWallet Pay adds a smart-contract escrow layer and rich UI on top of Mantle:

1. Escrow-first payments

   • Funds are locked in the SafePay contract instead of going directly to the recipient.

2. Claim-based receiving

   • Recipients explicitly claim funds (HBAR or ERC‑20) with a transaction ID.

3. Refunds for unclaimed & misdirected funds

   • If a payment is never claimed, the sender can refund and recover the funds.

   • This gives a safety net for wrong-address transfers, as long as the funds remain unclaimed in escrow.

4. Bulk Transaction Manager

   • Send many payments in a single transaction to save cost and simplify operations.

5. Smooth onboarding

   • Web3Auth enables social logins alongside traditional wallets.

Result: a safer, more forgiving payment flow that still feels like normal crypto.
