Your first trade

Before you begin

Section titled “Before you begin”

Open app.degenx.fun, connect your wallet, and select Arc mainnet (5042). Hold USDC on Arc and leave some available for transaction fees. USDC on another chain is not automatically available on Arc.

Native USDC and ERC-20 USDC on Arc are two interfaces to the same balance. You do not need to wrap USDC to trade. See Arc and USDC.

Buy a token on its curve

Section titled “Buy a token on its curve”
  1. Open an existing token and check its full contract address.
  2. Confirm the token is still on its bonding curve.
  3. Enter the USDC amount. Review the base fee, creator tax, any active anti-snipe tax, and minimum received.
  4. Approve the launchpad to spend USDC. Prefer an allowance appropriate to your intended spend.
  5. Sign the buy transaction and wait for its receipt.

A fresh wallet does not need a trading invitation or allowlist entry. Protocol-blocked wallets cannot enter through the launchpad.

Sell a token on its curve

Section titled “Sell a token on its curve”

Approve the launchpad to spend the token, choose the amount, review the USDC quote and minimum received, then sign the sell. Selling does not require trading allowlist membership. Curve sells stop when the curve is complete; after successful graduation, use the pool.

After graduation

Section titled “After graduation”

The app routes trading through the token’s Uniswap v4 pool. The spender and approval flow differ from a curve trade: the pool route uses Universal Router and Permit2. Review the wallet’s requested spender and amount rather than assuming your curve allowance applies.

What the test demonstrated

Section titled “What the test demonstrated”

On 15 September 2026, a fresh wallet outside the allowlist bought 0.10 USDC of ARCPRE and sold all received tokens for 0.09801 USDC. The difference was the buy and sell fees; gas was charged separately. This is historical execution evidence, not a quote for your next trade. See transaction links.

If a trade fails

Section titled “If a trade fails”

Check the chain, available USDC including gas, token allowance, launch state, minimum output, and current anti-snipe window. Refresh the quote before retrying. Troubleshooting explains common contract errors.
