Fees

BNB is the native token on Binance Chain, thus users are charged BNB for sending transactions.

Trading Fees on DEX

Trading fees are subject to complex logic that may mean that individual trades are not charged exactly by the rates below, but between them instead; this is due to the block-based matching engine in use on the DEX.

The current fee for trades, applied on the settled amounts, is as follows:

Trading fee can be queried at here. It's under the "params/DexFeeParam/". "FeeRate" and "FeeRateNative" are both under unit of 10^-6.

Fix Fee Table

The difference between Binance Chain and Ethereum is that there is no notion of gas. As a result, fees for the rest transactions are fixed. The details are showned in the table below:

• Current Fees Table on Mainnet

• Current Fees Table on Testnet

How to calculate multisend fee

bnbcli offers you a multi-send command to transfer multiple tokens to multiple people. 20% discount is available for multi-send transactions. For now, multi-send transaction will send some tokens from one address to multiple output addresses. If the count of output address is bigger than the threshold, currently it's 2, then the total transaction fee is 0.001 BNB per token per address. For example, if you send 3 ABC token,1 SAT token and 1 ABC to 3 different addresses.

[   {      "to":"bnb1g5p04snezgpky203fq6da9qyjsy2k9kzr5yuhl",      "amount":"100000000:BNB,100000000:ABC"   },   {      "to":"bnb1l86xty0m55ryct9pnypz6chvtsmpyewmhrqwxw",      "amount":"100000000:BNB"   },   {      "to":"bnb1l86xty0maxdgst9pnypz6chvtsmpydkjflfioe",      "amount":"100000000:BNB,100000000:SAT"   }]

You will pay on mainnet/testnet

0.0003 BNB * 5 = 0.0015 BNB

How are rewards distributed between validators?

you can use API to get the latest fee params.

The fee_forparameter indicate the different distribution way:

• 1 means rewards is only for block proposer

• 2 means rewards are shared among all validators

• 3 means fee is free.

How to query fees in every block

The rewards for Binance Chain validators are displayed in explorer. For example: in block 59947302, validator bnb1tpagqqqx36gq09kzw4f5a3a9sk3tq54dpl5ldn get 0.00005 BNB as rewards.

If you have a fullnode running, you can also get the rewards details exported. To achieve this, you need to set publishBlockFee to be true in your app.toml. To receive rewards stream, there aretwo options publishKafka and publishLocal

# Whether we want publish block fee changespublishBlockFee = trueblockFeeTopic = "accounts"blockFeeKafka = "127.0.0.1:9092"# Global settingpublicationChannelSize = "10000"publishKafka = falsepublishLocal = true

The rewards history are saved under {fullnode home}/marketdata/marketdata.json. For example,

Note: Quantities here are expressed without decimals, i.e. shifted by 10^8

Trading fees can be charged in different BEP2 tokens,
