Coinbase Bridge vs EigenCloud

cbBTC is Coinbase’s wrapped Bitcoin launched on Base and Ethereum to simplify DeFi access for exchange users. Custody is handled by Coinbase Prime with a daily on‑chain proof‑of‑reserve attestation signed by Deloitte. cbBTC is fungible 1:1 with native BTC and charges zero conversion fees during promotional periods.

EigenLayer is a restaking marketplace on Ethereum that lets ETH validators and LST holders opt‑in to provide crypto‑economic security to external ‘Actively Validated Services’ (AVSs). Participants earn additional yield by subjecting their stake to slashing conditions defined by each module, creating a shared‑security layer similar to Polkadot’s parachains. Mainnet restaking went live in April 2024, and over 4 million ETH had been opt‑in restaked by Q2 2025.
