Release Note Draft Snippet

[clemsos]

actually it will be easier to submit a second proposal (re-use the existing one) to bridge UDT to base, so we dont have to make estimate calculation about the balance

Exit UDT Uniswap positions

There are currently 3 positions owned by the DAO in the Uniswap UDT / WETH pool on mainnet. Liquidity for these positions is provided by the DAO treasury.

This proposal will result in exiting these positions by:

1. decrease liquidity to zero on all these positions
2. collect the UDT and WETH from the pools
3. burn the Uniswap position NFT

Once executed, all UDT and WETH tokens currently held in pools will be transferred back to the DAO's timelock.

You can check the current positions here: 638761, 663230, 694069 ).
