Fees
Target mainnet parameters for creating and trading tokens on Orba. Network gas, approvals, slippage, and price impact are shown separately because they are not Orba platform fees.
Mainnet draft — not yet effective. These values must be checked against the final deployed contracts and production interface before publication. The transaction presented by your wallet is authoritative for a specific action.
Target summary
Token creation fee
$5.00The target one-time fee for deploying a token and its bonding curve. The fee is paid in Arc's ERC-20 representation of USDC and sent to the protocol treasury.
A launch can require an approval transaction before the creation transaction. Both transactions consume network gas in native USDC. Gas is additional to the creation fee. The factory owner can change the creation fee within the contract's on-chain cap, so review the current wallet request before approving.
Bonding-curve trading fee
1%The target fee applies to each buy and sell while a token is on its bonding curve. On a 100 USDC buy, 1 USDC is allocated to fees and 99 USDC enters the curve. On a sell with a 100 USDC gross curve amount, 1 USDC is allocated to fees and the user receives 99 USDC before gas.
Accrues in the curve contract and is claimable by the recorded token creator.

AMM swaps after graduation
0.3%The AMM retains 0.3% of swap input in the pair reserves for liquidity providers. Orba and token creators have no protocol-fee switch or special withdrawal path. Graduation sends its LP tokens to the burn address; later third-party liquidity providers may still mint their own LP tokens and participate in fees earned while they provide liquidity.
The final router, pair bytecode, reserves, and transaction preview must be verified for the specific graduated token.
Referral accounting
0.1%Orba's target referral rate records 0.1% of eligible attributed bonding-curve volume. For 1,000 USDC of eligible volume, the off-chain record would increase by 1 USDC.
This is an accounting accrual, not an on-chain balance or automatic payment. It is intended to be funded from the protocol economics if a payout program is enabled. A future claim process would require separate eligibility, verification, minimum, timing, and legal terms. See the referral documentation.
Network gas and approvals
Arc uses native USDC for gas. Gas changes with network conditions and transaction complexity, so Orba does not promise a fixed cost. Wallets may display native USDC separately from the six-decimal ERC-20 USDC used by contracts even though they represent the same asset.
An ERC-20 approval is not a platform fee, but the approval transaction consumes gas and grants spending authority. Review the spender and amount; prefer the exact or smallest sufficient approval and revoke unused approvals.
Costs that are not Orba fees
- • Network gas paid to Arc's validator mechanism
- • Slippage caused by state changes before execution
- • Price impact caused by trade size relative to liquidity
- • Wallet, exchange, bridge, or third-party provider charges
- • Taxes or reporting obligations in your jurisdiction
Worked examples
Buying with 100 USDC
Token output depends on current curve state and the transaction's minimum output. Gas is additional.
Launching a token
The creator receives no initial token allocation. Any later creator purchase is a separate trade with its own fee, gas, and price impact.
What changes at graduation?
Curve trading and its 1% fee stop after successful graduation. Previously accrued creator and protocol amounts remain subject to their contract claim rules. Trading moves to the AMM, where the LP swap fee is 0.3% and gas, slippage, and price impact still apply. Graduation has no separate target platform charge.
