Fee Amounts

Most write transactions to the FIO Chain are subject to a fee paid in FIO Tokens and set by the Block Producers in the following way:

Each of the 21 scheduled BPs submits their desired fee amount of FIO Tokens for each blockchain interaction and amount of bundled transactions to be included with every FIO Handle.
Amounts submitted by active block producers are analyzed, and the fee is set at median of all submitted amounts.

Fee amounts for specific fee type can be obtained using the /get_fee endpoint.

For current fee amounts see <https://fio.net/fio-chain/fees>

Bundled transactions

When a FIO Handles is registered, it comes bundled with 100 gas-free transactions. This eliminates the need for a user to pay a per-transaction fee for many popular FIO Chain transactions.
