Etherex launches REX token on Linea with decaying fee mechanism

Etherex, a new DEX built on Linea (an Ethereum Layer 2 network by Consensys), officially launched its REX token on August 6. To prevent bot activity, initial REX buys carry a 50% fee that gradually decreases to 2% within 30 minutes.

Launched on July 28, 2025, Etherex is a collaboration between Linea, Consensys, and Nile. The platform uses a tokenomics model similar to Ramses v3: no team allocations and all fees go to token holders. In addition to REX, the ecosystem also includes xREX and REX33 — a model that allows users to buy and sell voting rights instantly without locking tokens for four years.

REX incorporates auto-compounding and x(3,3) tokenomics, aiming to build a “smarter” DeFi stack.

As of 3:00 a.m. ET, REX was trading at approximately $0.604 with a market cap of $213.5 million, according to Dexscreener.

Ethereum co-founder and Consensys CEO Joseph Lubin commented: “REX unlocks a new layer of liquidity coordination for Linea and the broader Consensys ecosystem, moving closer to a modular, programmable DeFi stack.”
