You may try Alpha Wallet [1] then, open source and supports all evm chains, use custom option for chains not already there.
[1]
https://alphawallet.com/I downloaded and tried it but unfortunately it only gives one single address by wallet/seed to receive funds like Trust wallet such cryptos?
Yes, it's EVM only wallet, I assumed from your previous responses that you were looking for an EVM wallet, hence suggested it. And yes, it's one address per seed, although it's easy to generate new addresses (by clicking '+' icon) but might be troublesome to save all these seeds.
unfortunately, in addition it only offers few blockchains to activate, and when you try to settle other ones like Dogecoin, Litecoin or Waves it doesn't give receiving address in the official format, only in hexadecimal one. So how do you use this wallet with such cryptos?
Bolded cryptos shouldn't be there in first place since it's EVM only, for those and other cryptos even I'm looking for all-in-one wallet kinda alternative too after the fall of Coinomi lately.
