Business model

Pairband monetizes through minimal, transparent USDC fees on Arc. There are no hidden spreads: every charge is quoted before you confirm, and trading fees are enforced in bytecode.

All fees below are denominated in native Arc USDC (6 decimals on-chain; the preview engine mirrors the same dollar amounts at 18 decimals).

Fee overview

Fee	Amount	When	Paid by	Recipient
Launch	$1.00 USDC	Token creation	Creator	Protocol treasury
Curve protocol	1.00%	Bonding-curve buy/sell	Trader	Protocol treasury
Curve creator	0.50%	Bonding-curve buy/sell	Trader	Token creator
Uniswap pair	0.30%	Post-graduation AMM swap	Trader	Pool reserves
Agent proposal	$0.25 USDC	Vault rebalance proposal	Licensed agent	Protocol treasury
Code cap	2.00% max	—	—	Hard limit in contracts

Launch and agent fees are flat USDC charges — not percentage skim — so small creators and vaults know the exact cost up front.

Launch fee

Creating a token on Pairband costs $1 USDC on Arc (LAUNCH_FEE = 1e6 in the launchpad). This covers:

• On-chain registration and metadata anchoring
• Anti-spam gatekeeping without KYC
• Indexing and discover feed placement

The fee is deducted from the creator’s Arc USDC balance at launch. If you also make a first buy, you need launch fee + buy size + curve fees in the same wallet.

Live on Arc testnet

The launchpad charges LAUNCH_FEE = 1e6 ($1 USDC) in create(). Connected wallets approve USDC, then broadcast create — the fee is pulled to the on-chain treasury. The preview engine mirrors the same $1 debit locally.

Trading fees

Bonding curve (pre-graduation)

Every curve trade pays:

• 1.0% to the protocol
• 0.5% to the token creator

Both are taken in USDC before reserves update. Failed swaps revert with no fee.

After graduation

Market orders route book → AMM. The Uniswap-style pair charges 0.30% on the input token; liquidity stays in the pool. LP tokens are burned at graduation — there is no withdrawLiquidity escape hatch.

See Trading for venue routing detail.

Agent fees (vaults)

Concentrated-liquidity vaults can designate an on-chain agent address. When policy.agent is set:

• Only the agent or curator may call proposeRebalance
• Each agent-initiated proposal costs $0.25 USDC on Arc, paid from the agent’s USDC balance
• The curator still executes after the proposal delay — the agent proposes; humans or multisigs approve by executing

Curator-initiated proposals do not incur the agent fee. This aligns incentives: automation pays per signal; discretionary curator moves stay free aside from gas.

Agent fees route to the vault protocol fee recipient (same treasury family as launch fees).

Where fees go

Stream	Default recipient
Launch fee	0x7EA5…7EA5 protocol treasury (testnet)
Curve protocol fee	Protocol treasury
Curve creator fee	Token creator wallet
Agent fee	Protocol fee recipient on the vault
AMM fee	Locked pool reserves

Treasury addresses are published in Contracts per network.

Why USDC on Arc

Arc is the settlement layer for Pairband:

• USDC is the quote asset for every launch
• CCTP v2 mints Arc USDC when traders bridge in from ETH, Base, Solana, and other domains
• Flat fees in USDC avoid volatile gas-token accounting and match how creators think about launch cost

What Pairband does not charge

• No subscription for browsing or paper trading in preview
• No withdrawal fee on demo faucet USDC
• No LP management fee after graduation (LP is dead)
• No fee on failed transactions

Example: creator launch + first buy

1. Creator connects wallet with $11 USDC on Arc
2. Pays $1 launch fee → treasury
3. First buy $10 USDC on curve → ~1.5% trading fees inside the quote
4. Token appears in Discover; creator earns 0.5% on all future curve volume until graduation

Roadmap

• On-chain launch fee in PairbandLaunchpad.create — live on Arc testnet (LAUNCH_FEE = 1e6)
• Agent fee on proposeRebalance when policy.agent is set — in vault bytecode (AGENT_FEE = 2.5e5)
• Optional creator fee share buyback — not live; curve creator fee is the current creator revenue
