Glad to hear you were able to regain access to your assets.
To explain the technical backend. Your Private Key (AKA SRP) is linked to a public address. The same priavte/public address pair can exist on any blockchain that uses the same method for generating keypairs. For Ethereum and other EVM compatible chains, this is derived from the BIP39 word list.
Essentially, if you have the key for that address on one chain, you have it for all compatible chains; because they’re created in the same way.
For a 12 word SRP, there are 1.465 x 10^2210 possible combionations. (the 24 word phrase that hardware wallets use by default adds another 638 zeros to that) At 1 per second, it would take over 30 million years to go through the 12 word list.
