Osmosis v20.2.1 🧪

This release provides a state-compatible update introducing an EIP-1559 style fee market to mitigate recent congestion issues. This new mechanism is designed to prevent block congestion caused by invalid transactions.

It calculates a transaction fee for each block (named base_fee), dynamically based on the volume of transactions.

If the blocks are consistently full, the transaction fee increases at a predefined rate, making spamming with invalid transactions less attractive to the sender. This increment continues until a maximum base fee is reached.

Conversely, if the blocks are empty, the base fee decreases to a minimum value.

Transaction Fee Calculation for Integrators

To query the current base fee from your node, use the /osmosis/txfees/v1beta1/cur_eip_base_fee endpoint on your node API Server.

For example:

curl https://lcd.osmosis.zone/osmosis/txfees/v1beta1/cur_eip_base_fee

# {
#   "base_fee": "0.002500000000000000"
# }

We suggest setting the transaction fees to 2x or 3x the current value. This approach may result in clients frequently overpaying transaction fees, but it is a precautionary measure to ensure stability during peak times. Be aware that this is a temporary solution, pending the integration of a more refined fee market mechanism into the consensus layer.
