Proposal to add ETHx/frxETH pool on Ethereum to the Gauge Controller


We are looking to join Frax’s frxETHBP & WETHR Program which will allow our ETHx/frxETH pair to grow with Frax and deepen liquidity for both ETHx and frxETH

ETHx Contract

ETHx Dapp (Private Beta)






Protocol Description:

Stader Labs is a multi-chain liquid staking platform currently live on 6 blockchains including Polygon, BNB Hedera, Near, Fantom etc. Stader Protocol’s native token is the SD Token. With $100M+ TVL and trusted by 50k+ stakers & 240K+ strong community, Stader’s coming to Ethereum with ETHx**

About ETHx:

ETHx is an ERC20 token which represents users’ staked Eth and the accrued staking rewards with Stader i.e. a c-token type liquid staking token. Users will be able to obtain ETHx by staking with Stader or by swapping it on DEX pools. ETHx has been in private beta for about a month with over 2400 Eth TVL.

Safety and security are paramount for Stader and the smart contracts across each of the chains have been audited at least twice to safeguard user’s funds. The ETHx smart contract is triple audited by leading smart contract security partners Sigma Prime, Halborn and Code4rena.


Curve is the ideal DEX for price-correlated swaps, given its stableswap invariant curve. And by being part of Frax’s WETHR program, we can enter the space in a more sustainable way for us while helping Frax on their goal to unlock WETH


  1. Governance: Stader’s governance is led by the Stader DAO - a wide variety of $SD holders who have a say in key decisions pertaining to the protocol. Here’s the Stader Governance Forum

    For ETHx, we have the Oracle Node Operator Genesis Committee of distinguished community members. Learn more about the ETHx ONO committee

  2. Oracles: ETHx Rate Provider

  3. Audits: Halborn Audit Report & SigmaPrime Audit Report

  4. Centralization vectors: Stader is a non-custodial and decentralized liquid staking solution based on DAO governance. $SD is Stader’s native governance token. ETHx will be based on the foundation of decentralization with permissionless node operators getting majority of the ETHx TVL as demand scales, starting with an initial allocation of 70%.

    The ETHx contract upgrades are managed by an Admin time-lock contract with a 6 on 9 Multi sig (2 Stader members and 7 external members) as the proposer. Learn more about how Stader envisions embracing the path of decentralization

  5. Market History: ETHx is new and recently integrated into Coingecko
