Magical Internet Money

Status: Work In Progress

Magical Internet Money is here to help manage your crypto assets.

Features

  • Multiple addresses
  • EVM chain crypto assets:
    • ETH and ERC-20 Fungible Tokens
    • ERC-721 and ERC-1155 Non-Fungible Tokens
    • ENS Names (ERC-721 and ERC-1155)
    • ERC-5564 Stealth Transfer support for ETH, ERC-20 and ERC-721 tokens (testing on Sepolia Testnet). Note that the ERC-1155 tokens are not supported under the current ERC-5564 Stealth Transfers
  • All data is stored in your local browser storage
  • Execute simply from GitHub Pages
  • No additional backend servers required
  • On-chain data is used where possible, supplemented with public data sources
  • Source code can be downloaded and run using e.g. anywhere in the ./docs folder

Requirements

  • Web3 browser, connected to Ethereum Mainnet or the Sepolia Testnet currently

Notes

This project is currently heavily under development. Clear your browser's LocalStorage and IndexedDB if this dapp is not operating as expected as the configuration data may have a new format.

TODOs

  • Base ERC-20/721/1155 event log scraping very slow - has a max number of blocks of ~10k
  • Disable unhandled Fungibles e.g. CryptoPunks, MoonCats, CryptoCats
  • Display total and individual Fungible balances

Add Stealth Meta-Address To Registry



Old Stuff

An implementation of ERC-5564: Stealth Addresses and ERC-6538: Stealth Meta-Address Registry (using address instead of bytes).

Test it at https://bokkypoobah.github.io/MagicalInternetMoney/ (WIP) connected to the Ethereum Sepolia testnet.


How The ERC-5564: Stealth Addresses Protocol Works

  • Alice wants to pay Bob in ETH/ERC-20/ERC-721 tokens
  • Bob generates a Stealth Meta-Address and provides this to Alice
  • Alice uses Bob's Stealth Meta-Address to compute a random Stealth Address that can be accessed only by Bob
  • Alice transfers the tokens to this address and announces the transfers in the ERC-5564: Stealth Address Announcer contract
  • Bob can access the private keys to their computed Stealth Addresses, using information included in the announcements
  • The ERC-6538: Stealth Meta-Address Registry allows any account to publish their associated Stealth Meta-Addresses

How This Dapp Works

This dapp:

  • Allows Bob's web3 attached account to generate a unique Stealth Meta-Address for each unique associated phrase
  • Allows Alice to compute a random Stealth Address using Bob's Stealth Meta-Address
  • Allows Alice to then execute the transfer to Bob's Stealth Address and announce the transfer to the Announcer
  • Retrieve all event logs published to the Announcer
  • Retrieves all event logs published to the Registry
