Regulated Money On A Public Ledger
A crypto product is two systems wearing one interface. On one side an exchange or wallet with balances, risk and compliance obligations. On the other, an irreversible chain where a signing error is final and every mistake is publicly readable.
Teams that treat it as a normal web build get the interface right and the custody model wrong. We start at the opposite end — keys, ledger and reconciliation first, product surface after — because that order is the difference between a launch and an incident.
- Custody and key management designed before the first screen
- A double-entry internal ledger that reconciles against chain state
- Compliance built in from scoping, not bolted on before an audit
What We Build In Crypto
The products behind our blockchain, exchange and wallet work.
Exchanges (CEX)
Matching engine, order types, wallet infrastructure, risk controls and the admin tooling an exchange is actually run from.
DEX & DeFi Protocols
AMMs, liquidity pools, staking and lending contracts, with the front end and indexing layer that makes them usable.
Wallets
Custodial and non-custodial wallets — multi-chain, MPC or seed-based — with recovery flows that ordinary users survive.
Crypto Payments
Merchant gateways, invoicing, settlement to fiat and crypto cards, with the reconciliation finance teams need.
Token & Launch Platforms
Token contracts, vesting, launchpads and distribution, written to be audited rather than to be launched fast.
Trading Systems
Trading bots, market making, copy trading and API layers built for latency and for surviving a volatile hour.
What Decides Whether It Holds
None of this is visible in a demo. All of it is visible in an incident.
Custody & key management
Hot, warm and cold separation, MPC or HSM signing, withdrawal policy and quorum — decided before anything is built.
Matching engine performance
Deterministic order matching that keeps its guarantees when volume spikes, with a replayable event log behind it.
KYC, AML & travel rule
Onboarding, screening, sanctions and reporting wired to your jurisdiction rather than a generic template.
Audit-ready contracts
Contracts written for review — tests, invariants and documentation prepared for an external auditor, not after one.
On-chain monitoring
Reorg handling, confirmation policy, stuck transactions and address screening watched continuously, not on request.
Ledger & reconciliation
A double-entry internal ledger reconciled against chain and bank state daily, so a discrepancy is caught the same day.
Chains And Infrastructure We Work On
Chain choice follows liquidity, fees and where your users already are. We build across the major ecosystems and will argue against one if it is wrong for the product.
Talk to our teamHow We Deliver
The security work happens first, because retrofitting it is how projects get exploited.
Scope and jurisdiction
Product, custody model and regulatory footprint pinned down together — they constrain each other.
Custody and ledger
Key management and the internal accounting layer built and tested before a single user-facing screen.
Product and chain layer
Trading, contracts or payments built on top, with monitoring and admin tooling delivered alongside, not later.
Audit, then launch
Internal review, external contract audit and a staged rollout with limits that lift as the system proves itself.
Bring Us The Hard Part
Custody model, compliance scope, matching engine, or the contract nobody wants to sign off — those are the conversations we are useful in. Start there.
