EchoDEX: Concentrated Liquidity AMM on Linea

2026-07-16

EchoDEX is a decentralised exchange built on Linea, ConsenSys's ZK-rollup on Ethereum. It offers both V2 constant-product and V3 concentrated liquidity pool types, with V3 consistently generating the majority of trading activity due to higher capital efficiency. EchoDEX serves as one of the native liquidity venues for the Linea ecosystem.

Fees are generated on each swap. Revenue is split between the protocol treasury, governance token stakers, and liquidity providers. V3 generates more fees than V2 due to the tighter price ranges and higher utilisation that concentrated liquidity enables. Linea's Ethereum equivalence made the EVM side of this adapter straightforward: the same Swap event structure used on Ethereum mainnet works here. The dual V2/V3 deployment required the adapter to support two different fee calculation paths: a common pattern for DEX adapters but still requiring careful abstraction to avoid duplicating logic.

All-time fees stand at $4,400, with about $12 in the past seven days and $1 in the most recent day. EchoDEX is a small protocol on a chain that is still growing its DeFi ecosystem, but tracking it contributes to complete coverage of the Linea DEX landscape. The numbers will grow as Linea attracts more users and liquidity over time.
