Live now: launch and trade on Ethereum, Base and Robinhood Chain. Bitcoin etching and the BTC bridge are being switched on next.

What is Carvy

Carvy launches real Bitcoin Runes in one click and makes them tradable at full speed on the chain where your community already is. You pick a name, ticker, picture and chain, approve once, and Carvy handles the rest: the bonding curve opens instantly, the Rune is etched on Bitcoin a few blocks later, and holders can move it 1:1 between Bitcoin and the trading chain whenever they like.

Supported chains

Each Rune is 50% Bitcoin and 50% the chain its creator chooses. Pairs per chain:

Robinhood Chain
Arbitrum Orbit L2 built for tokenized assets.
Pairs: ETH, WBTC, USDC
Ethereum
Deepest liquidity, WBTC native home.
Pairs: ETH, WBTC, USDC
Base
Cheap, fast L2 with cbBTC and a huge retail crowd.
Pairs: ETH, cbBTC, USDC
Solana
Sub-second trades, the home of memecoin speed.
Pairs: SOL, WBTC, USDC

Bonding curve

Every Rune starts on a constant product bonding curve priced in BTC, with virtual reserves of 0.04 BTC and 1,073,000,000 tokens. Payments in ETH, SOL, WBTC, cbBTC or USDC are converted to sats at the live price before they hit the curve, so every Rune shares the same BTC-denominated price path whatever chain it trades on.

When 793,100,000 tokens have been sold, the Rune graduates. One transaction, which anyone can send, moves the raised funds and the matching tokens into a full-range Uniswap V4 pool at the final curve price on Ethereum, Base and Robinhood Chain. Leftover tokens are burned and the liquidity stays locked forever.

Fees

Trading fee is 1% on every buy and sell. Half goes to the creator side, which the creator configures at launch:

  • Dev: paid to the creator wallet.
  • Holders: shared with every holder, pro rata.
  • Routed: paid in BTC to any Bitcoin address the creator chooses.

Creators can also set a creator tax at launch, up to 5% on buys and 5% on sells. It is paid to the creator fee wallet on every curve trade and keeps applying in the Uniswap V4 pool after graduation through the Carvy hook. It is fixed forever. Wallet transfers are never taxed.

Launching is free. Carvy pays the Bitcoin etching fee.

Buyback and burn

The other half of every fee goes to the platform. 20% of all platform fees are sent on chain to the buyback vault, which buys $CARVY on the market and burns it. $CARVY lives on Ethereum (Uniswap V4) and is omnichain: the same token moves between Ethereum, Base, Robinhood Chain and Solana with a fixed total supply.

Bridge to Bitcoin

Once a Rune is etched, any holder can bridge it to a Bitcoin Taproot or SegWit address. The tokens leave the trading chain and the same amount of the native Rune is released from custody, so supply on both sides always adds up to 1,000,000,000.

Testnet preview

This preview runs on test networks with test funds from the faucet on your Account page. Trades, balances and bridges are recorded by Carvy so you can try the full flow without risk. Mainnet adds the on-chain deposit contracts on each chain and the custody signer on Bitcoin.
