On testnet private keys uses a different format too.

I found this with all address prefixes: https://en.bitcoin.it/wiki/List_of_address_prefixes

Just like most of bitcoin forks use a different address format to prevent money losses. For example, Bcash now uses q..., bitcore uses btx...  bitcoingold uses g.... and so on.

Additionally, to prevent lazy developer from using same seed/private key on both testnet and mainnet.

Just like most of bitcoin forks use a different address format to prevent money losses. For example, Bcash now uses q..., bitcore uses btx...  bitcoingold uses g.... and so on.

Take note that bitcoin forks still support Bitcoin's legacy or/and Bech32 address format. New address format isn't useful if there's no wallet, merchant or exchange which support it.
