Proposal to add eBTC/wstETH to the Gauge Controller

Summary: This proposal, submitted on behalf of BadgerDAO and Lido, seeks to add the eBTC/wstETH pool’s gauge to the Gauge Controller on the Ethereum network.

Protocol Description: eBTC is a collateralized crypto asset, soft pegged to the price of Bitcoin and built on the Ethereum network. It is backed exclusively by Lido’s stETH and powered by immutable smart contracts with minimized counterparty risk. Designed to be the most decentralized synthetic Bitcoin in DeFi, eBTC allows anyone in the world to borrow BTC at no cost.

Motivation: The request to enable this gauge is motivated by several factors. Firstly, establishing Curve as a primary liquidity venue for eBTC will strengthen the protocol and enhance its composability and use cases. Secondly, Lido aims to expand the liquidity profile of stETH and views eBTC as a strategic pairing due to the synergies between the assets.

Additionally, the CDP nature of eBTC, backed solely by stETH with a 110% MCR requirement and no fees or interest rates, makes it the most capital-efficient way to long stETH against BTC in DeFi. Having a pool with this pair will enable a smooth path for most leverage operations, and we believe Curve is the perfect venue to handle this with the highest efficiency possible. The liquidity in this pool is expected to drive most of the leverage volume, resulting in high fees for the protocol.

Finally, Lido plans to incentivize LPs to adopt the pool. The communities of Lido, BadgerDAO, Curve, and Convex have historically collaborated closely, and this pool will further strengthen these ties, unlocking a variety of integrations and synergies.


  1. Governance: eBTC’s Minimized Governance framework is detailed in this forum post. The protocol’s contracts are immutable, with minimal parameters that can be modified via two Timelocks with 2 or 7-day delays. Only parameters that do not violate users’ trust assumptions can be changed.
  2. Oracles: The eBTC Protocol primarily relies on Chainlink for price data and is adding a secondary (fallback) oracle via governance. Details on the Chainlink Oracle setup can be found here.
  3. Audits:
  1. Centralization Vectors: The protocol has no major centralization vectors. Minimal governance is conducted transparently and distributedly, with robust timeclocks and monitoring. Contracts are immutable, and collateral types cannot be changed.

  2. Market History:

  • eBTC has maintained a strong peg to BTC since its launch (~2 months ago) ranging from 0.99 to 1.009.
