hack·a·chain — Specialist software for crypto finance

We didn't read about trading systems, payment rails, and DeFi protocols. We built them.

Money movement between TradFi and onchain is still broken in most places. We've spent 15+ years on that exact problem — building the rails, the execution systems, and the protocols. We know where the bodies are buried.

Why it's hard — and why it matters

Most teams get either the finance depth or the crypto-native engineering. Rarely both. That gap is exactly where things break.

The typical fintech problem

Finance expertise without crypto depth

Understands payment rails, FX, compliance, and market structure. But hits a wall when the destination is onchain — smart contracts, liquidity protocols, and settlement finality work differently.

The typical crypto-native problem

Onchain fluency without finance structure

Knows the protocol layer cold — but underestimates FX risk, execution quality, and the operational reality of moving real money through real markets at scale.

hack·a·chain operates at that exact intersection. Our team has been on the trading desk, built the exchange infrastructure, shipped DeFi protocols, and delivered fintech systems end to end. We don't translate between the two worlds — we live in both.

Services

Four areas. One team that has
shipped in all of them.

We don't generalise. Each pillar maps to systems we've designed, built, and put into production.

Money Rails
The infrastructure that moves value — across borders, between banks, and from fiat to onchain.
FX execution and multi-currency routing
On/off ramp architecture and liquidity management
Payment rail integration — SWIFT, SEPA, local schemes
Settlement, reconciliation, and treasury systems
Trading Execution
Systems that price, quote, and execute — built for the speed and precision that real markets demand.
Algorithmic market making and quoting engines
Multi-venue order routing and smart execution
Inventory risk management and position controls
Low-latency execution infrastructure and connectivity
Market Design
The architecture of markets — from liquidity structure and fee mechanics to protocol economics.
Liquidity pool architecture and AMM design
Market microstructure and fee mechanism design
RFQ and OTC system design
Incentive design and tokenomic modelling
Onchain Protocols
Smart contract systems built for real financial applications — production-grade, not proof of concept.
DeFi protocol development and integration
RWA tokenisation and onchain settlement infrastructure
Cross-chain liquidity and bridge architecture
Onchain compliance, access control, and custody hooks

Infrastructure optimisation — across all domains

We also go into systems that are already
running and make them better.

Most clients aren't starting from zero. We come in mid-flight — auditing execution pipelines, reducing infra spend, and fixing the reliability issues that only appear at volume.

What we optimise

Latency reduction

Profiling and re-architecting execution hot paths — order routing, pricing engines, settlement confirmation — to shave the milliseconds that matter in live markets.

Reliability & resilience

Hardening systems against failure modes that only appear under load — circuit breakers, graceful degradation, failover routing, and alerting that fires before your client does.

Infrastructure cost reduction

Auditing cloud spend, data pipeline costs, and over-provisioned compute across high-throughput financial systems — and restructuring to handle the same load for less.

Throughput & scalability

Re-engineering bottlenecks in transaction processing, settlement queues, and data ingestion — so systems that work at 10x can still work at 100x without a rewrite.

Domains

Where we go deep.

Four niches we know from the inside — the problems, the edge cases, and what production-grade actually means in each one.

FX and cross-border money movement is still one of the hardest problems in finance.

Corridors behave differently. Liquidity is fragmented across banks, non-bank providers, and crypto venues. Hedging crypto exposure against fiat risk is a discipline most teams underestimate until it costs them. We've built the execution layer — and we've been on the desk managing the risk.

What most teams miss

FX isn't just a pricing problem. It's a liquidity sourcing, timing, hedging, and settlement problem simultaneously. Systems that handle the happy path break under stress — high volatility, thin liquidity, or failed settlement. We design for the edge cases first.

Who we work with

Built for teams operating at the sharp end.

We work best with teams who know what they're building and need a partner with the domain depth to match.

WhoThe problem they bringWhat we deliver
Fintechs & neobanks
Need to move money faster, cheaper, and across more corridors — without rebuilding core infrastructure from scratch.
FX execution, ramp infrastructure, and payment rail integrations that sit cleanly on top of existing systems.
Talk to us →
Crypto-native teams
Strong on the protocol side — but hitting the limits of what in-house engineering can deliver on execution, market design, or financial infrastructure.

TradFi crossover
Understands financial markets but needs a technical partner who speaks both sides — finance structure and onchain execution — without translating between them.
Architecture and builds that bridge TradFi logic and crypto infrastructure — settlement, compliance, and market access included.
Talk to us →
OTC desks & exchanges
Need production-grade execution and market-making infrastructure — not off-the-shelf tools, not a two-person dev shop.
Custom quoting engines, inventory systems, and execution infrastructure built by people who've run the desk themselves.
