Our verdict on Etherex Legacy

6.2/10

Etherex Legacy suits users already active on Linea who want a concentrated liquidity DEX with x(3,3) incentives and are comfortable with DeFi risk. Its main strength is the focused design, with listed audits and a stated Consensys backing. The main caveat is the small TVL of about $310,000 and the unexplained Legacy label, so confirm the current contracts and start with small amounts.

What is Etherex Legacy?

Etherex Legacy is the DefiLlama entry for Etherex, a decentralized exchange built on the Linea network. The homepage presents it as the flagship concentrated liquidity exchange on Linea, where users can trade, provide liquidity and earn through x(3,3) tokenomics. It also states the project is backed by Consensys.

The listing has been tracked since July 2025 and reports about $310,000 in total value locked, with a small weekly change of 0.5%. Its native token is REX, and two audits are listed. One report links the launch to Nile Exchange and Ramses v3 technology.

The Legacy label is not explained, so readers should confirm on the official site which pools and contracts are current.

How Etherex Legacy works

A decentralized exchange lets people swap tokens directly from their wallets using smart contracts instead of an order book. Prices come from liquidity pools that other users fund. In a concentrated liquidity design, those providers choose a price range for their capital, which can give traders deeper liquidity near the current price.

Etherex adds the x(3,3) model on top. It is described as a more fluid version of ve(3,3), where token holders and liquidity providers share incentives and fee flows instead of being locked for long periods. The exact reward rules are set by the protocol and are not detailed.

The exchange operates on Linea. One report says it builds on Ramses v3 technology and is an upgraded version of Nile Exchange. The listing here is labeled Legacy, and the project does not explain what that covers.

6 features

Key features

Concentrated liquidity pools

Liquidity providers can place capital in chosen price ranges. This can make trading more capital efficient than full-range pools, but it needs more active management.

x(3,3) tokenomics

Etherex describes its tokenomics as x(3,3), a more fluid and accessible take on the ve(3,3) model that rewards participation in the protocol.

Linea-native exchange

The exchange is built for the Linea network, so trades and liquidity positions settle there with lower costs than Ethereum mainnet.

REX token incentives

REX is the project's own token, tied to incentives and governance-style participation under the x(3,3) design.

Trading and liquidity provision

Users can swap tokens and provide liquidity to earn from the activity in the pools.

Audits listed

Two audits are listed for the project on DefiLlama, though the reports are not described.

Pros and cons

What we like

Focused on concentrated liquidity, which can use capital more efficiently than full-range pools.
Built on Linea, where transaction costs are lower than on Ethereum mainnet.
Two audits are listed on DefiLlama.
The homepage states backing from Consensys, which is a known name in the Ethereum ecosystem.
Clear purpose: a native exchange for Linea assets with its own token incentives.

Watch out for

TVL of about $310,000 is small, so large trades may face thin liquidity and slippage.
The x(3,3) model is complex, and rewards depend on the REX token, which can be volatile.
It runs only on Linea, so users must bridge assets there first.
The Legacy label is not explained, which may confuse users about which pools or contracts are involved.
Fee levels, team details and audit reports are not published.
Concentrated liquidity positions can lose value through impermanent loss if the price leaves the chosen range.

Etherex Legacy fees

Etherex does not publish a fee schedule. As on most concentrated liquidity DEXes, trading fees are typically set per pool and paid to liquidity providers, and the exact tiers appear in the app when you choose a pool.

Beyond protocol fees, users pay network gas on Linea and may pay bridge costs to move assets in. Slippage can also be a real cost in pools with low liquidity.

Is Etherex Legacy safe?

DefiLlama lists two audits for the project, but the reports, auditors and findings are not described. Like any DEX, it carries smart-contract risk, and users keep custody of their own funds in their wallets while interacting with the contracts. Liquidity providers also face impermanent loss.

The team and legal structure are not detailed, and no hack or shutdown is reported. The Legacy label means users should verify they are interacting with the contracts the project currently points to. Check for approvals you no longer need and beware of similarly named tokens, since an unrelated token called EtherEx (ETX) also exists.

6 steps

How to get started with Etherex Legacy

1
Set up a wallet that supports Linea and keep a small amount of ETH on Linea for gas.
2
Bridge the assets you want to trade or provide from Ethereum or another chain to Linea.
3
Open the official Etherex site and check which pools and contracts you are using, since this listing is labeled Legacy.
4
Review the pool fee tier and current liquidity before swapping, and set a slippage limit.
5
If you want to provide liquidity, choose a price range and read about impermanent loss first.
6
Start with a small amount, and revoke token approvals you no longer need.

Etherex Legacy FAQs

What is Etherex?

Etherex is a decentralized exchange on the Linea network. It combines concentrated liquidity pools with an x(3,3) token model built around the REX token. Its homepage calls it the flagship concentrated liquidity exchange on Linea.

What does Etherex Legacy mean?

Which blockchain does Etherex use?

Etherex runs on Linea. Users need a compatible wallet and must hold assets on Linea, which usually means bridging from Ethereum or another chain.

What is the REX token?

The REX token is the native token of Etherex. It sits at the center of the x(3,3) model, which is described as a more flexible version of the ve(3,3) design. Exact emission and reward terms are set by the protocol and should be read on its site.

Is Etherex related to Nile Exchange?

Is Etherex safe?

DefiLlama lists two audits for the project, but the audit reports themselves are not described. Audits reduce but do not remove smart-contract risk. Providing liquidity also carries impermanent loss, and token prices can fall.
