An implementation of ERC-5564: Stealth Addresses and ERC-6538: Stealth Meta-Address Registry (using bytes32 instead of bytes).

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

• 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

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

Click [+] in the Addresses screen to generate a new Stealth Meta-Address.

Click [Update] to update the Stealth Meta-Address keys.

Click on the [eye] button to sign with your web3 wallet to view the Spending Private Key.

Note: Duplicated stealth payments to the same receivers for testing
