Swap fees

Naos charges a 0.1% flat fee on every trade. Integrators can set an additional custom fee on swaps using the integrator and fee parameters on GET /api/v2/quote:
ParameterDescription
integratorWallet address that receives the fee
feeFee in basis points (10-500 bps, i.e. 0.1%-5%)
The integrator fee is deducted from the swap output on-chain. It is split 80/20: 80% is sent to the integrator wallet, 20% goes to the Naos protocol. This split is enforced by the router contract — no off-chain settlement needed. 
const quote = await api('/api/v2/quote?' + new URLSearchParams({
  tokenIn: NATIVE,
  tokenOut: TOKEN,
  amount: '1000000000000000000',
  slippage: '500',
  trader: wallet.address,
  chain: 'BASE',
  integrator: '0xYourFeeWallet',
  fee: '100' // 1%
}))

Bridge fees

Naos charges a 0.25% fee on all bridge transactions. The fee is automatically included in the bridge quote — no additional parameters needed.
