Raft Finance: Decentralized Stablecoins with a Twist

Raft Finance is a decentralized finance (DeFi) protocol focused on creating and managing stablecoins backed by liquid staking tokens (LSTs). Unlike traditional stablecoins that might be backed by fiat currency reserves or volatile cryptocurrencies, Raft leverages the yield-generating properties of LSTs to improve capital efficiency and stability.

At the heart of Raft lies the R stablecoin (R). R is an over-collateralized stablecoin, meaning that each R token is backed by a value of LSTs greater than $1. This over-collateralization acts as a safety buffer against price fluctuations in the underlying assets and helps to maintain the peg to the US dollar. Users can mint R by depositing supported LSTs, such as stETH (staked ETH) from Lido, as collateral. This process creates a debt position against the collateral.

A key differentiator of Raft is its utilization of LSTs. These tokens represent staked assets on proof-of-stake blockchains, entitling holders to staking rewards. By using LSTs as collateral, Raft effectively allows users to borrow against their staking positions without needing to unstake and miss out on yield. The staking rewards earned on the collateralized LSTs are used to offset the cost of borrowing R, making the system more sustainable and attractive to users.

To maintain the R stablecoin's peg to $1, Raft employs a mechanism called stability fees and a redemption mechanism. Stability fees are charged on outstanding R debt, incentivizing users to repay their loans when the R price trades above its target. The redemption mechanism allows users to redeem R for the underlying collateral at a fixed price, creating an arbitrage opportunity that helps to maintain the peg when the R price trades below $1.

Furthermore, Raft incorporates a governance token (RAFT) that allows holders to participate in the protocol's decision-making process. RAFT holders can vote on proposals related to parameters such as stability fees, collateral types, and risk management strategies. This decentralized governance structure ensures that the protocol evolves and adapts to changing market conditions.

The benefits of using Raft Finance include:

• Capital Efficiency: Users can leverage their staked assets without unstaking and missing out on yield.
• Decentralization: The protocol is governed by RAFT token holders, ensuring transparency and community control.
• Stability: The over-collateralization and stability mechanisms help to maintain the R stablecoin's peg to $1.

Like any DeFi protocol, Raft Finance carries certain risks, including:

• Smart Contract Risk: Bugs in the smart contracts could lead to loss of funds.
• Liquidation Risk: If the value of the collateral falls below a certain threshold, the position may be liquidated.
• Depeg Risk: Despite the stability mechanisms, the R stablecoin could potentially depeg from $1.

In conclusion, Raft Finance offers a novel approach to creating decentralized stablecoins by leveraging the yield-generating properties of LSTs. By providing a platform for users to borrow against their staking positions, Raft aims to improve capital efficiency and foster a more sustainable DeFi ecosystem. However, users should carefully consider the risks involved before participating in the protocol.
