    Unit

    Bridge · Bitcoin, Zcash, Ethereum +5

    Unit is an asset tokenization layer that lets users deposit native assets such as BTC, ETH and SOL onto Hyperliquid and withdraw them again. It holds close to $1 billion in TVL, but no audits are listed and the model relies on a guardian set.

    Lombard BTC.b

    Bridge · Bitcoin

    Lombard BTC.b is a 1:1 Bitcoin representation meant to move BTC across multiple chains for DeFi use, backed by a consortium of validators. It suits Bitcoin holders who want DeFi access, but it adds bridge and validator trust risk.

    Bridge · XRP Ledger, Ethereum, BNB Chain +28

    Wan Bridge is the cross-chain bridge from the Wanchain project, linking more than 30 networks including Bitcoin, XRPL, Ethereum and Solana. Its range is the draw; small TVL and self-reported security claims are the caveats.
