As a test/experiment, I created a small smart pool on balancer using my Trezor hardware wallet connected to my Metamask.

The creation of the pool was easy enough, but I kept getting errors when I tried to add or remove liquidity. I decided that something was wrong and decided to unpack the pool and bring my coins back into my local wallet. I found this difficult, but was able to retrieve 3 of the 4 coin positions. I got errors on the 4th coin and now the pool itself is not visible at the balancer interface. I see the remaining BPT tokens at etherscan, so it is there, but balancer cannot see it.

No idea what to do. Any help appreciated.

Did you ever get help with this? What is the fourth coin? It’s possible that it is incompatible with Balancer and cannot be withdrawn.
