Stealth Addresses

A Solidity implementation of ERC-5564 stealth addresses for offchain usage based on crysol.

Introduction

StealthAddresses is a library for common stealth address operations. Note that most of the functionality is vmed, meaning it is only executable offchain.

See script/Example.s.sol for usage example.

$ forge script script/Example.s.sol
> [ALICE] Created new address funded with 1 ETH
> [BOB]   Created two key pairs for their stealth meta address
> [BOB]   Created and published stealth meta address: st:eth:0x030403...18c1e
> [ALICE] Generated stealth address from Bob stealth meta address
> [ALICE] Send 1 ETH to stealth address and published the stealth address
> [BOB]   Found out the stealth address belongs to them
> [BOB]   Computed the stealth address' secret key
