Fees

Orba has a simple, transparent fee structure. All fees are paid in USDC — the native gas token on Arc. There are no hidden fees, no subscriptions, and no charges for graduation.

Quick summary

Token creation (one-time)$5.00
Trade fee (buy & sell, bonding curve)1% of trade
AMM swap (post-graduation)0%
Referral reward0.1% of referral volume
Gas (network fee)< $0.01 / tx (USDC)

Token Creation Fee

$5.00

A one-time fee charged when launching a new token. Covers deployment of the MemeToken and BondingCurve contracts on Arc.

Paid via USDC transferFrom — you'll be prompted to approve the 5 USDC spend before launch. The fee goes to the protocol treasury. The token creator does not pay for gas separately — gas is paid in the same USDC and is typically a fraction of a cent.

Trade Fee

1%

Applied to every buy and sell on the bonding curve. The fee is deducted from the trade amount before it hits the curve — so a 100 USDC buy sends 99 USDC into the curve and 1 USDC to fees. Split equally between the token creator and the protocol:

Creator share
50% of fee (0.5% of trade)
Accrued in the BondingCurve contract. Claimable by the token creator at any time via the curve's claimCreatorFees function.
Protocol share
50% of fee (0.5% of trade)
Accrued in the BondingCurve contract. Claimable by the protocol owner. Funds ongoing development and operations.

AMM Swap Fee (post-graduation)

0%

After a token graduates to the AMM, swaps on the DEX are free — there is no swap fee. This is intentional: the bonding curve (not the AMM) is where fees are captured. The AMM exists to provide permanent, locked liquidity for graduated tokens. Note: you still pay Arc gas for the swap transaction, which is typically a fraction of a cent.

Referral Reward

0.1%

When someone you referred trades on Orba, you earn 0.1% of their trade volume (10 basis points). This is 10% of the 1% trading fee — the protocol shares its half of the fee with referrers.

Get your referral link from your profile page. Attribution is first-click-wins: the first referrer whose link a wallet clicks is permanently credited. See the docs for full details.

Rewards are currently tracked off-chain for display and leaderboard ranking. On-chain USDC payout to referrers is on the roadmap.

Gas (Network Fees)

USDC-native

On Arc, USDC is the native gas token — you pay for transactions in USDC, not a separate utility token. Gas fees are stable and predictable, typically a fraction of a cent per transaction. No ETH or other token required.

Token launch (deploy 2 contracts)~$0.01
Buy / sell on bonding curve~$0.001
AMM swap~$0.001
USDC approval (one-time per token)~$0.001

Gas estimates are approximate and based on Arc testnet. Actual costs may vary slightly with network conditions.

No Hidden Fees

  • ✓ No deposit or withdrawal fees
  • ✓ No platform listing fees
  • ✓ No subscription or membership fees
  • ✓ No fees for token graduation to the DEX
  • ✓ No fees for AMM swaps (post-graduation)
  • ✓ Slippage tolerance is user-controlled, not platform-imposed
  • ✓ No fees for claiming creator or protocol fees

Example: Buying 100 USDC of a token

You spend$100.00 USDC
Trade fee (1%)−$1.00
Net to bonding curve$99.00
→ Creator fee (0.5%)$0.50
→ Protocol fee (0.5%)$0.50

Example: Selling tokens for 100 USDC

Tokens sold (worth at current price)$100.00 USDC
Trade fee (1%)−$1.00
You receive$99.00 USDC
→ Creator fee (0.5%)$0.50
→ Protocol fee (0.5%)$0.50

Example: Launching a token

Creation fee−$5.00
Gas (deploy 2 contracts)−$0.01
Total cost to launch~$5.01 USDC

The 1 billion token supply is minted to the bonding curve for free — you don't buy your own tokens at launch. You earn the 0.5% creator fee on every trade made by other users.

Example: Referral earnings

Your referral buys 1,000 USDC of a token$1,000.00
Your reward (0.1%)+$1.00 USDC
If they trade $100K volume over time+$100.00 USDC

What happens to fees at graduation?

When a token graduates (market cap reaches $25.00K), the bonding curve is retired. Creator and protocol fees accrued up to that point remain claimable from the curve contract forever — they are not lost. After graduation, there are no more trade fees (AMM swaps are 0%). The creator's ongoing revenue stream ends at graduation by design — the creator fee is a reward for building a token that reaches graduation, not a perpetual tax on trading.
