Automated market maker DEX on Binance Smart Chain

Peer-to-peer trading through smart contracts, with liquidity rewards paid on-chain.

The challenge

Decentralised exchanges on Ethereum work, but transaction cost and settlement time price out smaller trades entirely — the fee can exceed the trade.

And on-chain, a contract bug is permanent and public. There is no patch-and-deploy once liquidity is committed.

Our approach
01

Build on BSC

Binance Smart Chain was chosen for faster transaction times and lower fees than the Ethereum network, making smaller trades viable.

02

Trade through contracts, not order books

An automated market maker model executes trades through smart contracts rather than matching orders, removing the need for a counterparty to be present.

03

Reward liquidity

Users providing liquidity to the platform earn rewards paid in the platform's native cryptocurrency.
