Onchain payments today are fully transparent. Every transfer exposes both the sender and recipient, making wallets easy to track and link to real identities. Most stealth address protocols rely on ECDH (elliptic curve Diffie-Hellman). When quantum computers become practical, ECDH breaks. Any payment made today could be deanonymized in the future.
SPECTER uses ML-KEM-768 (NIST FIPS 203), a post quantum key encapsulation standard, instead of ECDH. Payments stay private today and remain private even against adversaries with quantum computers. Send to anyone using just their ENS (.eth) or SuiNS (.sui) name. SPECTER generates a fresh, one-time stealth address for every payment. The recipient is the only one who can discover and spend from it. To the rest of the world, it looks like funds went to a random address with no connection to anyone.
SPECTER also integrates with Yellow Network to enable private trading through off-chain state channel settlement, combining stealth addresses with high-performance order execution.
