Restaking

Restaking means taking ETH you’ve already staked and committing it again to secure more services, stacking a second layer of yield on top of the first. Liquid restaking goes a step further: you get a tradeable token representing the position, so the value isn’t locked away while it earns.

Why it matters: that liquid token is what makes “spend your staked ETH” cards work. Because the position is represented by an asset you still hold, a card can take it as collateral and let you borrow against it to spend — your ETH keeps earning the whole time instead of sitting idle to back a balance. The trade-off is layered risk: you’re now exposed to the restaking protocol on top of plain staking, and a sharp price drop in the collateral can trigger liquidation, so the yield isn’t free.

For example: ether.fi Cash is built on this. Your weETH — ether.fi’s liquid restaking token — sits in your own vault as collateral, and the card’s Borrow Mode lets you spend against it at 4% APY while the weETH keeps accruing restaking yield. As of June 2026. The catch is that weETH carries a 55% loan-to-value limit, so the borrowing headroom is smaller than for a stablecoin, and the position can be liquidated if its value falls too far.
