Zero-knowledge proofs for privacy you can verify.
ZK circuits and zkVM programs for privacy, identity, compliance and verifiable computation, from proofs of solvency to private payments.
[ 01 ]The short answer
What is Zero-Knowledge Proof Development?
Zero-knowledge proof development builds systems that prove a statement is true without revealing the data behind it: that a user is over 18, that an account is solvent, that a payment is compliant, or that a computation ran correctly. Modern zkVMs let us write provable programs in Rust instead of hand-built circuits. We use ZK where it solves a real problem, usually privacy with selective disclosure or verifiable offchain computation, and keep the trusted setup, proving cost and audit plan in view.
What you get
- Circuits or zkVM programs
- Verifier contracts
- Prover infrastructure
- Security review of circuits
- Performance and cost benchmarks
[ 02 ]What we build
The pieces, built to last.
- 01
zkVM programs
Provable Rust programs on SP1 or RISC Zero for verifiable offchain computation.
- 02
Circuits
Circom and Noir circuits where performance demands hand-built constraints.
- 03
Private payments
Shielded balances and transfers with selective disclosure for auditors.
- 04
ZK identity
Prove age, residency or KYC status without sharing documents.
- 05
Proof of reserves
Prove solvency without exposing every customer balance.
- 06
Onchain verifiers
Gas-efficient verifier contracts and proof aggregation.
[ 03 ]Where it pays off
Where it earns its keep.
- 01
Private payroll and payments
Pay people onchain without publishing every salary.
- 02
Compliant privacy
Privacy pools and attestations that keep bad actors out.
- 03
Exchanges and custodians
Regular, verifiable solvency proofs.
- 04
Verifiable AI and compute
Prove that a model or job ran as claimed.
[ 04 ]How we deliver
Four steps, one team, start to finish.
The same people scope it, build it and stay after launch. Timings are typical for a first release; we agree yours after the deep dive.
- 01Week 1
Threat model and spec
Who can move money, under what conditions, and what happens when a key, an oracle or a bridge fails. Written down before code.
- 02Weeks 2 to 8
Build with invariants
Contracts or programs with unit, fuzz and invariant tests, least-privilege roles, timelocks and rate limits from the first commit.
- 03Weeks 6 to 10
Review and testnet
Internal review, an independent audit where value is at stake, and a public testnet with monitoring wired in.
- 04Ongoing
Mainnet and watch
A staged launch with caps, live alerting on admin actions and outflows, and a rehearsed incident plan.

One signature, every asset: the EIP-7702 delegation trap
ProblemA single EIP-7702 authorization routes every future call from an account to delegate code; phishing sites disguise it, and early analysis found most mainnet delegations pointed at copy-pasted sweeper contracts.ProposalTreat delegation as the most dangerous signature a wallet asks for: allowlist audited delegate contracts, show the target in plain language, simulate effects, scope permissions with session keys, and make revocation one tap.Read the proposal - Stablecoins3 min read
The GENIUS Act turns stablecoin compliance into an engineering problem
ProblemStablecoin issuers and payment platforms face new reserve, disclosure, AML, sanctions and freeze obligations, while most stablecoin stacks were built for speed with compliance added by hand.ProposalCompliance by architecture: role-separated freeze and burn powers with audit trails, screening at every edge, travel-rule data in the payment flow, reserve data published on a schedule, and reconciliation that closes daily.Read the proposal
[ 07 ]FAQ
Questions buyers ask.
Proving costs have fallen sharply with zkVMs and GPU provers. For many uses they are now fine; we benchmark your workload before committing.
Yes, with selective disclosure and association sets that let users prove they are not linked to illicit funds. Ethereum's privacy roadmap is moving in this direction.
Yes, specialised ones. Under-constrained circuits are a common and serious bug class.
