Puffer (PUFFER) is a cryptocurrency designed to enhance Ethereum's scalability and decentralisation through innovative infrastructure solutions. It focuses on next-generation rollup technologies, including "Based Rollups," which integrate liquidity restaking (LRT) and a pre-confirmation technology known as AVS. These advancements aim to streamline transactions and improve network efficiency.

Puffer is used primarily within the Ethereum ecosystem to improve transaction throughput and reduce costs through its rollup solutions. Its "Based Rollups" technology enables more efficient handling of transactions by bundling them off-chain and subsequently validating them on the Ethereum blockchain. This process ensures greater scalability while maintaining decentralisation. Additionally, Puffer supports liquidity restaking, allowing users to earn additional rewards by staking their assets in multiple pools simultaneously.

The founders of Puffer are Lawrence Jin and Hsiao-Wei Wang.
