Private DeFi on
Bitcoin and Ethereum.

Tacit issues assets on Bitcoin and carries them into a confidential pool on Ethereum by zero-knowledge proof, and back. Amounts and owners stay hidden. Every balance recovers from one key.

    How it comes together

    1. On Bitcoin

      Tacit issues assets like TAC in Bitcoin transactions, with their amounts hidden. Anyone can rebuild the same state from the chain alone.

    2. Between the chains

      A zero-knowledge proof of Bitcoin’s own blocks carries a note into the pool on Ethereum, and the pool’s state back. No federation or multisig signs anything.

    3. On Ethereum

      One immutable pool holds tETH, TAC, cBTC and cUSD as private notes. ETH-only pools on Ethereum, Base, Robinhood Chain and MegaETH take private payments too.

    TAC · A Privacy Coin on Bitcoin L1

    Tacit protocol’s first asset: 21,000,000 issued once on Bitcoin, no mint key. Transfers hide their amounts, its shielded pool hides who received them, and sats swap into it peer to peer. Airdropped to bootstrap one private currency on both chains (claimable by 5,599 zFi shareholder wallets on Bitcoin and 8,652 holders on Ethereum), it keeps spreading through points and farms to grow the anonymity set, and gets each new Tacit protocol improvement first.

    Farm TAC

    Deposit into a pool and earn TAC every second, and withdraw whenever you like. The public pool takes ETH and TAC from your wallet; the private pools take private tETH or its partner asset, either one alone or both, so what you hold stays hidden.
