Wraith Protocol Contracts

Stealth address smart contracts for the Wraith Protocol multichain privacy platform. EVM contracts in Solidity (Hardhat), Stellar contracts in Soroban/Rust, Solana programs in Anchor/Rust, CKB scripts in Rust (RISC-V).

Every payment generates a fresh one-time stealth address so on-chain observers cannot link sender, recipient, or transaction history.

EVM Contracts (Solidity)

Contract	Description
ERC5564Announcer	Minimal singleton that emits Announcement events per ERC-5564. No storage, no access control.
ERC6538Registry	Stealth meta-address registry per ERC-6538. Supports direct registration and delegated registration via EIP-712 signatures with replay-protected nonces.
WraithSender	Atomically transfers ETH or ERC-20 tokens to a stealth address and publishes an announcement in a single transaction. Supports batch sends and optional ETH gas tips.
WraithNames	Privacy-preserving .wraith name registry. Maps human-readable names to stealth meta-addresses with ownership proven via secp256k1 spending key signatures.
WraithWithdrawer	EIP-7702 delegation target for gas-sponsored stealth address withdrawals. A sponsor pays gas on behalf of the stealth address holder.

Stellar Contracts (Soroban/Rust)

Contract	Description
stealth-announcer	Emits stealth address announcement events. No storage.
stealth-registry	Maps addresses to 64-byte stealth meta-addresses with auth-gated registration.
stealth-sender	Atomic token transfer + announcement via the announcer contract. Supports batch sends.
wraith-names	Name registry with SHA-256 hashed storage keys, reverse lookup, and lowercase alphanumeric validation (3-32 chars).

Solana Programs (Anchor/Rust)

Program	Description
wraith-announcer	Stateless event emitter for stealth address announcements via Anchor emit!().
wraith-sender	Atomic SOL transfer + announcement in one instruction. Also supports SPL token sends.
wraith-names	PDA-based name registry. Names are 3-32 chars (lowercase alphanumeric/hyphens), stored as PDA seeds.

CKB Scripts (Rust/RISC-V)

Script	Description
wraith-stealth-lock	Lock script that verifies secp256k1 signatures against blake160(stealth_pubkey) in args[33:53]. Embeds the ephemeral public key in args[0:33] — the Cell itself is the announcement. Delegates to on-chain ckb-auth via exec_cell.
wraith-names-type	Type script for .wraith name registration cells. Validates 66-byte cell data (spending + viewing public keys). Ownership proven by the cell's lock script. Supports create, update, and release (destroy).
