Blockchain · Service Decentralized exchange (DEX) development

DEX development: AMM and order-book designs, concentrated liquidity, perpetuals, aggregator routing, MEV protection and audited smart contracts.

In short

A decentralized exchange (DEX) lets people trade tokens directly from their own wallets, with smart contracts holding liquidity and settling every trade on-chain. Most DEXs use an automated market maker (AMM), where trades are priced by a formula against pools of tokens supplied by liquidity providers; others run on-chain order books or offer perpetual futures. Because the contracts hold everyone's funds, security is the product.

When you need it

Signs this is the right service

  • You want trading without taking custody of user funds.
  • Your token or ecosystem needs on-chain liquidity and price discovery.
  • You are building perpetuals, an aggregator or a specialised AMM for a new asset type.
  • An existing DEX needs new pool types, a migration or a security review.
What's included

What you get

Pool and pricing design

Constant-product, stable-swap or concentrated-liquidity pools — chosen for the assets you trade — or an on-chain order book where it fits.

Swap routing

Routing across pools and, where useful, other DEXs, with slippage limits and deadlines on every trade.

MEV protection

Private transaction submission and slippage controls to reduce sandwich attacks on your users.

Liquidity incentives

LP positions, fee tiers and reward programs designed so they cannot be farmed and dumped.

Interface, indexing and audit

A trading interface, an indexer for pools, prices and history, and contracts prepared for external audit.

How we deliver it

The process

  1. 01

    Market design

    Which assets, which pricing model, how fees flow and who provides liquidity.

  2. 02

    Invariants first

    Pool maths and accounting rules written down and fuzzed against the implementation.

  3. 03

    Build and simulate

    Contracts tested against simulated trading, extreme prices and manipulation attempts.

  4. 04

    Audit and launch

    External audit, a guarded launch with caps, and monitoring of pools and oracles.

Questions

DEX development: common questions

Should we fork an existing DEX?

Forking a well-audited codebase can be sensible, but licences differ and changes reopen the security question. Uniswap v4 hooks let you add custom behaviour to proven pools instead of forking the whole protocol.

What is an AMM?

An automated market maker prices trades with a formula against pools of two or more tokens, instead of matching buyers with sellers. Liquidity providers deposit tokens into the pools and earn trading fees.

What is MEV and why does it matter?

Maximal extractable value is profit taken by reordering or inserting transactions — for example sandwiching a user's trade. Slippage limits and private transaction submission reduce how much is taken from your users.

Can a DEX support perpetual futures?

Yes. Perpetual DEXs add margin, funding rates, liquidations and oracle pricing, which raises the security bar considerably. We scope that work separately from spot trading.
