Fees

What BlankFX charges on swaps, transfers and payments, and where each fee goes.

Fees

The fee is always shown on the quote, before you confirm.

Swap fees

Swap	Base fee	Can rise to
Same-currency (e.g. USDC → USDT)	0.05%	base + up to 1.50% when the pool is unbalanced
Cross-currency (e.g. USDC → EURC)	0.10%	base + up to 1.50% when the pool is unbalanced

The extra inventory fee applies when the coin you are buying is running short in its pool. It is zero while that coin’s balance stays within a normal band and ramps up as the balance falls further. Buying a coin the pool holds plenty of costs the base fee.

On cross-currency swaps the rate itself also moves with size and pool balance (see Swaps). That price movement is separate from the fee.

Transfer fee

When a swap or payment delivers to someone else’s wallet (a send, a payment link, a point-of-sale payment), a transfer fee of 0.05% applies. Swaps back to your own wallet don’t pay it.

Where fees go

Fee	Goes to
Swap fee	80% to the pool’s suppliers, 20% to the BlankFX treasury
Transfer fee	BlankFX treasury

Gas

• Gasless swaps (from $100, after a one-time Permit2 approval): BlankFX currently pays the network fee.
• Swaps under $100, token approvals and deposits/withdrawals: you pay normal Ethereum gas from your wallet.

Earn

There is no fee to supply to or withdraw from a pool, and no performance fee on earnings. You pay only gas.

Agent payments

An AI agent paying a payment link over x402 pays the invoice amount plus the normal transfer fee, on top. The merchant receives the full invoice amount. There is no separate agent fee. BlankFX pays the gas to submit the payment; the agent pays gas only for its one-time Permit2 approval. See Agent payments.
