Navigate to the swETH/bb-a-WETH pool on Pendle.
You now need to zap out, and have two options depending on where you want to move your liquidity:
A. PT swETH Pendle pool
If you want to move your liquidity into the newly created swETH only Pendle pool, then output swETH and follow the instructions below (2A) for depositing into Pendle PT swETH.
B. Balancer
If you want to move your liquidity into the new Balancer pool, then output the swETH-bbaweth Balancer LP token, and follow the instructions below (2B) for depositing into Balancer.
Note that only LPs in the new Balancer pool are eligible for the 2x pearl boost.
Navigate to the new PT swETH pool on Pendle and deposit your swETH. You can either Zap in or Manually Add Liquidity, but make sure that you use zero price impact mode to minimize slippage.
