Osmosis v19.0.0 🧪

on GitHub

This v19 major release adds taker fee logic to the poolmanager, improving fee handling and income distribution. The release also fixes a bug in the superfluid protocol.

This upgrade is governed by Proposal 606, which aims to upgrade the Osmosis codebase to the v19.0.0 software tag at block height 11317300. This is estimated to occur on Tuesday, September 5th, at UTC 16:00.

Block times have high variance, so please monitor the chain for more precise time estimates.

Features

• Taker Fee: Implemented taker fee logic in the poolmanager when executing swaps. All swap logic messages must go through the poolmanager to incur taker fees. Fees accrue in two separate txfees module accounts: one for staking rewards and another for the community pool. (#6034)

Bug Fixes

• v19 Upgrade Handler: Fixed an issue in the superfluid protocol during upgrades. (#6190)
• Token Factory Events: Fixed events for mintTo and burnFrom in the x/tokenfactory module. (#6195)
• Superfluid EpochEnd Hook: Addressed a panic edge case in superfluid's After EpochEnd hook by applying a conditional function for CL multiplier updates. (#6195)

Additional Information on Taker Fee

The taker fee changes how swap fees are handled and adds another layer of income distribution to staking rewards and the community pool. This upgrade only introduces the fee logic as the initial taker fee will be set to 0 (zero).
