What wallet should we use then? I haven't been able to try out many wallets (yet). Just looking for a open source non-custodial wallet. I am using trust wallet for some times now, but as we all know it's closed source which is the issue. Apart from that, I don't use CEX/DEX that much often, only when I need to cash out or something like that.
There are many open source wallets but many of them doesn't support that much of cryptocurrency.
You’re surely right, the open source wallets we have are mostly those for bitcoin only storage, those for multi coin storage are definitely limited. The most popular open source wallet you will see for multi coins is the unstoppable wallet but it also has limited number of coins although it is updated regularly. So for large number of coins you will have to go for open source hardware wallets. The likes of mycelium and MetaMask are other options but just like TrustWallet they are closed source even though they claimed to open source.
