Project Description

I want to send tokens to a friend that has never used crypto before.

Traditionally, I would ask them to install metamask, they would proceed to download it and send me their address, and I would then send them the tokens.

Wouldn't it be cool if we could send them a link that held crypto such that as soon as they onboarded they could play around with those tokens?

Also, if I wanted to send tokens to my favorite Twitter KOL, they would want a way to receive the tokens without doxxing their wallet address to me

The key insight here is that embedded wallets plus simple use of a hash function allows users to sign in with google to claim the tokens trustlessly

How it's Made

This app is best viewed on a mobile browser! It is built with next pwa and is mobile first.

Walrus:

  • Store hashed passwords so they are not forgotten by the user
  • In case the passwords are wiped from local storage, we can still retrieve password hints from the blob ids

The Graph: We use this to make sure users aren't submitting a duplicate password!

Dynamic:

  • Embedded wallet so users can claim without a wallet

Supported Chains:

  • Base Sepolia
  • Skale
  • Unichain
  • Polygon ZkEVM
  • Story Protocol
  • AirDAO
  • Gnosis Chain
  • Flow Testnet
  • Hedera
  • Zircuit
  • Morph
