Dust Protocol
Private finance protocol on EVM chains. Two primitives: stealth transfers (send tokens without on-chain link) and privacy swaps (trade ETH/USDC without traceability via Uniswap V4 hooks + ZK proofs).

└── Output to stealth address (no link to deposit)
Key Concepts
Stealth Key Derivation
wallet_signature = sign("Dust Protocol stealth key", walletAddress)
entropy = PBKDF2(signature + PIN, salt, 100000 iter, SHA-512)
spendKey = entropy[0:32] // secp256k1 scalar
viewKey = entropy[32:64] // secp256k1 scalar
metaAddress = (spendKey*G, viewKey*G) // registered on ERC-6538
