How boun.fun works

What is boun.fun

boun.fun is the interface for launching and trading tokens on Circle’s Arc Network. Every launch opens a Uniswap V3 pool paired with native USDC. Liquidity is locked. There is no bonding curve to graduate through.

• Quote asset is always USDC
• LP is locked at launch
• Creator fees accrue from trading volume
• Bridge USDC onto Arc with Circle CCTP when you need gas or liquidity

Launch a token

1. ConnectUse a wallet on Arc Testnet with enough USDC for the fee and gas.
2. DescribeUpload an image, set name and ticker, add an optional narrative and socials.
3. Optional buyDev buy lets you take a first position at launch, capped as a share of supply.
4. Approve and launchApprove USDC, pay the 1 USDC launch fee, and deploy the token with a locked Uniswap V3 pool in one flow.

Launch fee is 1 USDC. Network gas on Arc is also paid in USDC.

Trade

Open any token page to buy or sell through the embedded Uniswap pool. Quotes and fills settle in USDC. Charts and the trade tape update from the indexer after the first swap.

• Buys and sells use the live pool, not a simulated curve
• Slippage and size matter. Start smaller if the pool is thin
• After people trade, creators claim fees from the same token page

Bridge USDC

Need USDC on Arc? Use Bridge. Circle CCTP burns USDC on a source chain and mints native USDC on the destination after Iris attestation.

1. Pick a routeInto Arc or out of Arc, then choose the external CCTP chain.
2. BurnUSDC burns on the from chain via TokenMessenger. Keep the burn transaction hash.
3. Attest and mintWhen Circle Iris returns an attestation, mint on the destination. If attestation is slow, you can finish mint later with the same burn tx.

Protocol bridge fee is 0.30%, skimmed on Arc. This fee is separate from the launch fee.

Fees

Of every pool trade fee, about 0.70% of volume goes to the creator and 0.30% to treasury (70% creator · 30% treasury of the pool fee). Collect from the token page when volume exists.
