Fees

NT is the native token on NexDAX Chain, thus users are charged NT 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:

Transaction Type Pay in non-NT Asset Pay in NT
Trade 0.1% 0.05%

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 NexDAX 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

Fees are variable and may change over time as governance proposals are proposed and voted on. The current fees table for Mainnet as of 2021-03-21 is as follows:

How to calculate multisend fee

eth-cli 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 NT 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:NT,100000000:ABC"

      "amount":"100000000:NT,100000000:SAT"
   }
]
You will pay on mainnet/testnet

0.0003 NT * 5 = 0.0015 NT

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 NexDAX Chain validators are displayed in explorer. For example: in block 59947302, validator bnb1tpagqqqx36gq09kzw4f5a3a9sk3tq54dpl5ldn get 0.00005 NT 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 changes
publishBlockFee = true
blockFeeTopic = "accounts"
blockFeeKafka = "127.0.0.1:9092"
# Global setting
publicationChannelSize = "10000"
publishKafka = false
publishLocal = 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
