Sendo Proof-of-concept

This is an open-source proof of concept of a Tiplink alternative for distributing crypto assets via a simple link that can be shared with anyone even if you don't know their wallet address or they don't have a wallet.

Features

  • One click link creation and sharing
  • One click claiming of assets
  • Gasless transactions when claiming assets
  • Web-based wallet when using web3auth
  • Guide to create a non-custodial wallet and move all assets if the receiver wants to move from web3auth wallet to a non-custodial wallet

How it works

  • You connect your wallet, select the token you want to send and the amount
  • You deposit the assets and the link is created
  • You share the link with anyone you want to send the assets to
  • They open the link and claim the assets to a new wallet (made with web3auth) or to their existing solana wallet by connecting it

Tech stack

  • Next.js 13 with app direcory for the frontend
  • Next.js API routes for the backend
  • Nextauth for authentication with Solana wallet
  • Web3auth for creating a new wallet for the receiver if they don't have one
  • TailwindCSS and Shadcn UI for styling

Self hosting

Prerequisites

  • MongoDB database (you can create a free one on MongoDB Atlas)
  • Web3auth project (you can create a free one on web3auth.io)
  • Optional but highly recommended: Sentry Project (you can create a free one on Sentry)
  • Solana Mainnet RPC (You can use Helius, extrnode, etc)

Steps

  • Clone the repo and install dependencies with pnpm i
  • Create a .env file and add the DATABASE_URL variable by setting it to the MongoDB connection string
  • Create a vault keypair with node scripts/genKeypair.js
  • Create a .env.local file and add in the rest of the environment variables (see .env.example for reference)
  • Run the app with pnpm dev

You can now host it on your favourite cloud provider like Vercel, Netlify, etc.
