Protocol Description:

Elixir is a modular DPoS network built to power liquidity on orderbook exchanges.

​Elixir is cross chain and composable: enabling orderbook DEXs to natively integrate Elixir into their core infrastructure to unlock retail liquidity for pairs, among other exciting use-cases. The network serves as crucial underlying infrastructure allowing for exchanges and protocols to easily bootstrap liquidity to their books.

​Elixir has 30+ native integrations into the core infrastructure of leading DEXs.

deUSD ("decentralized US Dollar") is a fully collateralized synthetic dollar powered by the Elixir Network. Minted by stETH and sDAI, deposited collateral is used to short ETH, creating a delta neutral position.

Through leveraging this funding rate basis trade on Ethereum, the Elixir network creates a synthetic dollar capturing positive funding rates. Even in a negative funding rate environment however, deUSD is built to be resilient.

The asset is used as the preferred collateral within Elixir's ecosystem, with most Elixir-powered exchanges natively accepting it. This enables users to earn yield on their assets while boosting orderbook liquidity across a host of orderbook exchanges. The long-term vision of deUSD will be far reaching, serving as a superior cross-chain DeFi-native money.

There is currently over $100m of TVL in deUSD pools on curve (deUSD / USDT, deUSD / USDC, deUSD / DAI, deUSD / FRAX).

Motivation:

Elixir is seeking to establish this Balancer pool as the primary source of liquidity for sdeUSD on Ethereum. E-CLP’s asymmetric concentrated liquidity profile offers capital efficiency improvements.

Specifications:

1. Governance: Elixir currently operates with a multi-sig wallet. The protocol is planning to transition to decentralized governance soon.

2. Oracles: Elixir’s mainnet sdeUSD rate provider has been reviewed here.

3. Audits: Elixir's deUSD token and related staking contracts were audited by Quantstamp and has an ongoing bug bounty program. More here.

4. Centralization vectors: Centralization vectors currently are around upgradeability via proxy multi-sig and front-end hosting.

5. Market History: Elixir has seen significant growth in TVL since launch with TVL over $100M.

The balancer pools are already live and are available on Ethereum
