STYX PROTOCOL // DEVELOPMENT ROADMAP

Building Private Finance

What runs on devnet today, what was built and then paused or retired, and what is being built next.

Devnet Only

Devnet only, test SOL, no real funds. Not externally audited. v1’s internal, AI-assisted audit reported 79 confirmed findings, 1 of them critical (README).

One square per item on this page, counted from the lists below. The shipped list keeps paused and retired work, each marked with its state, and neither is counted as in use.

Actively building

  1. Styx v2

    Live on Solana devnet at styx.cash since 2026-10-07: one private balance that pays any amount up to 10 SOL. Built on security profile R: the Poseidon2 hash, a four-element fingerprint, verifier challenges from a cubic extension field and a new verifier program. Our third internal attack test (2026-10-07) found no link between payer and payee beyond the accepted timing and amount limits. Next: the live checks of its two last fixes, an attack test on the new record format, and the external review. Subscriptions are parked for deeper work.

  2. External Security Audit

    An external review by independent cryptographers and Solana auditors, starting from the internal AI-assisted audit (79 confirmed findings, 1 critical), before any mainnet deployment.

  3. Mainnet Launch

    Mainnet is for v2 only, after the external review, an attack test on the new record format, and a pass that trims the programs’ size and launch cost. v1 never goes to mainnet.

  4. Internal Network Mapping

    Map internal transaction flows to improve privacy routing and reduce on-chain fingerprinting across the protocol.
