Company profile
researched Aug 2026Affine DeFi (previously Alpine) is a decentralized finance protocol operating two main product lines. Affine Restake offers stETH-based liquid restaking with what the company describes as instant entry and fast withdrawals, delegating deposits to operators, onboarding AVSs, and sharing airdrops with users. Its liquid restaking tokens, ultraETH and ultraETHs, are positioned as Symbiotic- and EigenLayer-compatible LRTs and are accessible through a dedicated restaking app at restaking.affinedefi.com.
The second product, Affine Earn, provides cross-chain yield baskets denominated in USDC, ETH, and MATIC, with strategies ranging from AAVE and Compound lending yield to leveraged recursive staking positions described by the company as up to 10x boosted. Earlier positioning described Affine as a protocol for cross-chain, smart yielding strategies for crypto investors.
The protocol publishes documentation covering its risk engine, points program (Affine ultraPoints), technical architecture, security roadmap and audit reports, and lists ecosystem, AVS, operator and DeFi partner categories, as well as a governance token section. Public metrics such as TVL, unique wallets and points emitted are displayed on the company website but were not resolved in the retrieved page.
