Coinfair

Coinfair is a decentralized exchange built on opBNB, the Layer 2 network of BNB Chain, where users connect a non-custodial wallet to swap tokens or supply liquidity for yield. Relying on opBNB's Optimistic Rollup architecture, it processes most transactions off chain and posts compressed data back to the mainnet, reaching roughly 4000 TPS with per-transaction fees below $0.001. As a spot-swap entry point in the opBNB ecosystem, Coinfair inherits the network's EVM compatibility and low gas, letting users trade DeFi in a self-custodial manner.

Coinfair is positioned as a lightweight DEX in the BNB Chain ecosystem for on-chain traders who want low fees and high throughput, using Layer 2 settlement to shorten confirmation times and cut participation cost. Its interface follows the common DEX interaction pattern, letting users accustomed to centralized exchanges migrate smoothly to on-chain swapping.
