Buy and sell

Every coin trades on a real Uniswap v4 market, priced and settled in USDC.

Every ubi.fun coin is a real Uniswap v4 pool from its first block, not an internal orderbook or a bonding-curve simulation. You trade directly against on-chain liquidity. Because the cash side of every market is USDC, prices and proceeds are already in USDC with no wrapping or bridging.

Finding coins

The Markets page lists every coin with live prices, sparklines, volume, and holder counts, polled every few seconds:

  • Trending / New / Top / High Vol chips re-rank the table.
  • The star adds a coin to your watchlist. Starred coins never drop off your list, however old they get.
  • Hover a coin’s row to reveal and copy its contract address.
  • The FLOOR badge marks coins whose creator routes earnings into automatic buybacks. See Auto buyback and the floor.

Trading

Open any coin’s page for the chart, trade history, holder list, and the swap panel:

  1. Connect a wallet. Use a browser-extension wallet or WalletConnect. If your wallet doesn’t know the Arc network yet, the app adds it for you.

  2. Buy or sell. Enter an amount in USDC (buys) or tokens (sells). The quote includes the 1.25% platform fee. There are no other charges.

  3. Confirm. Arc finalizes fast; your balance and the chart update within seconds.

Where your fee goes

The 1.25% you pay on a swap is the entire engine of the platform: it pays the coin’s creator, its holders (including you, if you hold), its buyback floor, and whoever referred the volume. Nothing else on ubi.fun charges you anything. The exact split is in Where every fee goes.
