Speaking of PolkaDot, there are two different types of cryptocurrency called the same way. Ufortunately, only Polkadot as ERC20 token is supported, the mainnet token is not implemented.
Solana (SOL) is not supported by Trezor firmware.
Feel free to see the full list of supported tokens and coins from our website https://trezor.io/coins/. You will find the information which device and what applications support the particular cryptocurrency.
At the moment, we are in the process of setting up a new strategy for implementing new coins into Trezor. However, there is no ETA, or plan to integrate these coins, currently.
Honestly, not sure what’s your suggestion. It’s upon the project itself how do they address their coin. If it’s misleading for a similar name, it’s not Trezor fault.
