[Ondo US dollar yield](https://www.coingecko.com/de/munze/ondo-us-dollar-yield) with the arbitrum token address `0x35e050d3c0ec2d29d269a8ecea763a183bdf9a9d` cannot be used for swapping even though its part of a abalancer pool.  
What could be the reason?

Ideally, you make a PR to the tokenlist. Then the token is whitelisted for trading. Note that in certain instances we might block trading because of smart contract risk :[GitHub - balancer/tokenlists](https://github.com/balancer/tokenlists)

Also if it is a yield bearing asset, the token needs to go through review in our rate provider repository: [GitHub - balancer/code-review](https://github.com/balancer/code-review)

Feel free to open a ticket in our Discord to get further assistance.
