Fixr
AB.About

The darkroom was built
by people who work quietly.

Fixr is built by an anonymous collective of cryptographers, infrastructure engineers, and designers from the Solana ecosystem. We use red safelights because the silver halide is sensitive and the work is slow. We build the same way.

01.Philosophy

Three commitments.

  1. 01

    The primitive stays small.

    One contract, one circuit family, one SDK. The more a privacy primitive does, the easier it is to break. We keep the darkroom small.

  2. 02

    Selective disclosure, not obfuscation.

    Fixr is not a mixer. Every proof carries a public predicate. The user picks which. Everything else stays latent.

  3. 03

    Compliance is a feature.

    We ship first-class sanctions and jurisdiction proofs. If the regulator can audit the proof, the user never has to hand over the wallet.

02.Roadmap

Where the darkroom goes.

  1. Q2 2026

    Open the darkroom

    Public landing, mock proof flow, litepaper v0.1. First feedback cycle with early fixers.

  2. Q3 2026

    First exposures

    SP1 integration behind the same UI. Token-2022 $FIXR launched. Initial predicate library (balance, nft, activity).

  3. Q4 2026

    SDK general availability

    TypeScript SDK 1.0. Rust and Python parity. Partner integrations with three Solana protocols.

  4. Q1 2027

    Compliance pack

    Sanction proof, jurisdiction proof, KYC proof as first-class predicates, all selective-disclosure only.

  5. Q2 2027+

    Cross-chain verification

    Verify Fixr proofs on EVM chains via Wormhole. Extend the primitive outside Solana while keeping the darkroom here.
