Offline address generation means exactly what it sounds like: generating an address on a machine that is offline, i.e. not connected to the internet. If you don't even know what offline address generation is, then you reply to that question saying either you don't know what they mean or you have not tried generating an address offline.

Offline transaction generation means exactly what it sounds like: creating and signing a transaction on a machine that is offline. Since signing transactions requires data from the blockchain (which thus implies that you had to be online at some point), offline transaction generation usually refers to signing where the signing is done on an offline machine.

We have been trying to generate address + privateKey pair compatible with xxxcoin (using secp256r1 instead of `secp256k1`) and using your prefix (PUBKEY_ADDRESS = 50).
Here is the example of the address that we’ve got: MMyevnCKFexH8785tWVveFxyiE9YqMjGMX.
Unfortunately xxxcoin client replies as Invalid xxxCoin address

we are using bitcoinjs-lib to generate addresses (to be precise - this version `bitcoinjs-lib-secp256r1`).

Have you ever succeeded with offline address generation and offline transaction generation using any programming language?

Some guy asked like above, then how can I reply?
xxxcoin is based on 0.8 version maxcoin (keccak algorithm), and  is now integrating process of some exchange.
