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. Prices and proceeds are in USDC with no wrapping or bridging: the cash side of most markets is USDC, and v3 tokens, which trade against an asset such as gold, are routed through that asset for you.

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 token’s swap fee: 1.25% for tokens launched before v2, 1.5% to 5% for v2 tokens, and a buy fee and a sell fee of 1.5% to 5% each for v3 tokens, shown on the token page. For v3 tokens the quote also includes the pair market’s fee (0.05% for gold). There are no other charges.

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

v3 tokens

A v3 token trades against an asset such as gold, but you still pay and receive USDC. One transaction swaps your USDC into the asset on its Uniswap market and the asset into the token, and the reverse when you sell. Buys can also be paid in EURC or cirBTC: the same transaction first swaps them to USDC on their own Uniswap market. The token page notes the route under the swap panel.

  • Anti-snipe fee. Right after a v3 token launches, buys may pay a higher fee that falls every second to the normal buy fee, within at most 10 minutes. The token page shows the live rate and a countdown; sells never pay it.
  • Dividends in the asset. A v3 token’s holders are paid in its pair asset, gold for gold-paired tokens.

Where your fee goes

The swap fee you pay is the entire engine of the platform: it pays the coin’s creator, its buyback floor, the daily holder pool for UBI holders, and whoever referred the volume. On tokens launched with a creator vault, part of it also pays the token’s own holders, see Creator vaults and holder dividends. Nothing else on ubi.fun charges you anything. The exact split is in Where every fee goes, and what the same trade costs and pays on another launchpad is in How ubi.fun compares.
