Network Fees
What each network charges, who pays, and fee sponsorship.
Fees by network
| Network | Fee charged in | Paid by | Can be sponsored |
|---|---|---|---|
| EVM | As quoted (gasToken) | The wallet, unless sponsored | Yes, except XAUT |
| Bitcoin | BTC, on top of the amount | The wallet | No |
| Spark | No fee between Spark wallets | — | — |
| Solana | USD₮; the customer needs no SOL | The wallet, unless sponsored | Yes |
| Tron | USD₮ | The wallet | No |
| TON | USD₮ | The wallet | No |
Get fee quote returns the fee (gas, gasToken), what the customer pays (userCost), whether it is sponsored, and the most the wallet can send.
The Bitcoin fee follows current network fee estimates.
Fee sponsorship
With sponsorship on, your business pays the network fee and the customer pays nothing: the quote shows sponsored: true and userCost "0". Sponsorship covers the EVM networks (except XAUT) and Solana. Shiga turns it on for your business, per network; contact us to enable it.
Leaving Spark
Transfers between Spark wallets are free. Leaving Spark is not: a withdrawal to a Bitcoin address and a Lightning payment each carry a fee. Price them with Quote Spark exit before sending. A quote moves no funds and needs no passkey; the matching spend does.
