Puffer Finance is an innovative project focused on Ethereum's Proof-of-Stake (PoS) network, offering a decentralized liquid restaking protocol. It allows users to stake ETH with a minimal requirement of just 1 ETH, compared to the standard 32 ETH required for running a validator. This significantly lowers the barrier to entry for individuals looking to participate in Ethereum staking. Additionally, Puffer provides liquid restaking tokens (pufETH), which can be used in decentralized applications while still earning staking rewards through EigenLayer's restaking services​.

One of the key features of Puffer Finance is its dual-layer reward system, allowing stakers to benefit both from Ethereum's PoS and restaking on external modular systems, enhancing capital efficiency and liquidity. The project also employs advanced slashing protection technologies, such as Secure-Signer and RAVe, to mitigate risks associated with validator penalties.

Puffer Finance has garnered significant attention, raising $18 million in Series A funding from prominent investors, including Brevan Howard Digital, Coinbase Ventures, and others. This funding is aimed at supporting its mainnet launch and further expanding its liquid restaking solutions​.
