Real artists ship.

We build apps and smart contracts on Solana.

And we have been building here since the start.

DeFi, MEV, and the systems underneath — modeled, optimized, and shipped by the people who run the network itself.

What we ship

01

DeFi.

DEXes, vaults, perps, staking — mechanism design that survives contact with real liquidity.

02

Apps.

Wallet-grade products people actually use, from first transaction to scale.

03

Smart contracts.

Anchor and Rust programs, audited, tuned for compute and account contention.

04

Dashboards.

Massive on-chain data — every transaction, network health, analytics in real time.

The deep end.

Most shops can't go here. We can — and we put it to work in production.

MEV & sub-slot execution

High-performance searchers and execution that lands inside the slot.

Optimal-input math

Multivariate calculus and PDEs for best on-chain profit — computed cheap.

Flash-loan systems

Moving real size from accounts holding nothing but gas.

Fee modeling

Beyond the public state of the art, in the most competitive markets.

Validator & RPC internals

Real stake, geographic stake mapping, latency engineering, custom client code.

Live network modeling

We model the chain under load — and know what ships next.

Heavy-lift launch

We don't just build on Solana. We run it.

Validators, RPC, MEV and latency systems, fee modeling beyond the public state of the art, and live network modeling — so the app we build for you lands every block.

Firedancer

Shipped.

True transactional privacy.

money came to mean dead presidents and the stamp of an army, but in reality, it's just an agreement between humans. technology should support that simplicity.
