Decentralized derivatives exchange Lighter has added Ether.fi's wrapped restaked ether ($WEETH) as eligible collateral for perpetual futures trading [1]. Under the platform's collateral parameters, the protocol credits 70% of the token's index value toward trader margin requirements [1].

To limit protocol-level exposure, Lighter established a platform-wide collateral supply ceiling of 1,000 $WEETH [1]. The 30% haircut applied to the liquid restaking token's index valuation serves as a buffer against market volatility and potential secondary market liquidity discounts [1].

## Liquid Restaking Collateral Rules

The integration enables participants holding wrapped restaked assets to leverage positions on the platform without liquidating their underlying yield-bearing holdings [1]. Liquid restaking tokens represent pledged ether ($ETH)—trading at $2,405 at the time of writing—earning consensus, execution, and restaking rewards while retaining secondary liquidity across decentralized finance.

Risk parameters restrict the total platform-level deposit size to 1,000 $WEETH while valuing posted assets at the 70% threshold [1]. The addition of Ether.fi's wrapped token follows broader industry expansion across perpetual venues, including previous derivatives integrations noted in [Telegram Wallet Partners With Lighter to Launch Leveraged Perpetual Futures](https://basisdesk.news/news/telegram-wallet-lighter-perpetual-futures-launch).
