Why Flint beats building your own prop AMM.

Over half of Solana's DEX volume already routes through aggregators. Flint runs the on-chain books and matches that flow — your quoting logic plugs in. No prop AMM to build, no stack to run.

01 — Why Flint

The AMM is the easy part. Everything around it is the job.

Matching, priority fees, landing, risk, custody, RPCs, aggregator integrations — that's the stack behind one quote. Building it from scratch is a second company.

Priority fees Bid per block, re-estimate on every quote, absorb every landing that misses. Managed

Transaction landing Jito tips, retries, preflight orchestration, RPC failover, 2am alerting. Included

Quote refreshes Full order rewrite every tick — state, fees, and compute on each update. Fair + offsets · one field per tick

Matching engine Write pro-rata allocation, audit it, and hold its liability. On-chain pro-rata

Risk tooling Staleness guards, spread widening, kill switches — ops you build yourself. SpreadProtect + staleness

Custody posture Key management designed for a desk that has never touched Solana. Cold admin · hot quoter

RPC infrastructure Self-host nodes or pay per request and hope they keep up. None to run

Aggregator routes Integrate Jupiter, DFlow, Titan, OKX DEX one by one. Pre-wired

Everything above Multiple teams, a roadmap, and an ops rotation One API

02 — How it works

Your quotes meet taker flow on-chain.

A multi-maker prop AMM merges every maker's quoting intents into one virtual book and fills pro-rata — so one desk is never locked into one AMM curve.

03 — The details

Six things you get without building them.

SDKs, risk guards, capital recycling, custody hygiene — the user-friendly layer that makes a desk's life genuinely easier.

Multi-maker pro-rata fills

Makers quote side by side and share flow pro-rata. Sharper pricing earns priority, but a step of latency doesn't shut you out.

Efficient quote refreshes

Update a fair price plus offsets instead of rewriting full order state. Oracle offsets, order lists, and linear distribution keep refreshes cheap.

Pre-integrated aggregators

Match incoming taker flow directly from Jupiter, DFlow, and Titan. OKX DEX is in progress.

USDC mini-books + synthetic crosses

One market account per token, an isolated USDC book per maker. JTO/SOL derives from JTO/USDC ÷ SOL/USDC on demand.

Capital recycling

A SOL ask brings USDC in, and that USDC instantly backs your SOL bid. Run a two-sided book from a one-sided deposit — fills cycle through your quotes.

Built for non-native desks

Standard APIs, auth-wallet safety, and direct team support. No Solana stack to learn before you can quote.
