# Web3SoundBox

We are a Cross chain Merchant Solution for offline retailers , enabling them access different EVM chains across one device.

Users can pay through any EVM supported chain through our unified QR code. 

## Features

- Merchant do need to confirm the tx themselves personally. Our sound Box catches cross chain events and emit exact USDC received though sound Speech Synthesis Utterance.

- Merchant doesn't need to be a crypto degen. All they need to do is enter their email id and use touch id as their passcode , thanks to `dfns` .

- Merchant gets created a safe Wallet under the hood on their preferred destination chain (currently ethereum) through their newly created `dfns` wallet.

- We use Axelar to send cross chain token transfer messages to send USDC to merchant through various source chains periodically by calling `Transfer_Tokens()` through the app automatically in the backend.

## Tech

- ### Axelar

  Completed tx on polygon - https://testnet.axelarscan.io/gmp/0xad59bad137330f0062768a4891789c94c10709a9ed142dfa48bb450acc505195:35

 Axelar has a cool feature of adding more gas. I liked it . Also I liked the UI , where we could see all txs clearly with hashes and diagrams.

- ### Dfns

  https://github.com/supernovahs/Web3SoundBox/tree/main/pages/api/dfns

  We are using Dfns to verify offline merchants easily. Then it is used to interact with SafeSDK and create wallets.

- ### Safe SDK

 We made changes in safe Sdk to incorporate Dfns with it . Our offline merchants receive USDC in their safe wallets under the hood.

- ### Celo

  We support Celo network in our contracts. Merchants can receive value using celo network as well .

- ### Polygon

  We use polygon networks to send cross chain message to send USDC to merchants .
