# Engineering for onchain finance

We help trading, tokenization and payments teams build their systems in-house, and get them right the first time.

- [Talk to an engineer](https://calendly.com/sevenlabs_/intro-call)
- [Our principles](https://www.sevenlabs.org/principles)

Financial systems are expensive to get wrong.

Real money moves through them from the first day, and mistakes are paid for in public.

That's the only kind of system we work on.

Trusted by Ergonia, DRW Labs, Solana Foundation, Lightcone and Eco.

## What we build

For companies moving onchain, and teams already there.

### Trading

Low-latency execution and market infrastructure, engineered for deterministic behavior under sustained load and adversarial conditions.

- Spot DEXs, AMMs and prop AMMs
- Order books and matching engines
- Perpetuals and derivatives venues
- Aggregators and smart order routers
- RFQ and OTC execution
- Market-making and execution bots
- Prediction markets
- Launchpads and bonding curves
- Market data pipelines and analytics

### Tokenization

Asset infrastructure with rigorous state guarantees, built to hold its invariants under regulatory constraints.

- Tokenized stocks and ETFs
- Tokenized bonds, treasuries and credit
- Tokenized funds and money market funds
- Vaults and yield strategies
- Principal and yield tokenization
- Structured products and options vaults
- Compliant tokens with transfer restrictions and KYC gating
- Proof of reserves and onchain reporting

### Payments

High-throughput payment infrastructure built for exact settlement and full reconciliation, resilient by default.

- Stablecoin issuance and mint/redeem
- Payment processing and merchant checkout
- Cross-border remittance and payouts
- On/off-ramp integrations
- Treasury and wallet infrastructure
- Settlement and netting between institutions
- Payroll and recurring payments
- Reconciliation and accounting data

## Open source

### Carbon

The most used indexing framework on Solana, built with the Solana Foundation. Teams use it to source, decode and process onchain data in production.
