Which network should this module sign for?

ChainBitcoin testnetStrongest quantum setupP2WPKH (tb1…). Address = HASH160(pubkey).Ethereum SepoliaEOA (0x…). Address = Keccak-256(pubkey)[12:].

Bitcoin-style addresses keep the public key hashed until its first spend. Combined with one-time keys, that is the strongest quantum-exposure setup: there is nothing for Shor's algorithm to attack until you sign.

Roto. All crypto runs client-side; nothing is sent to a server.

Read the threat model before trusting anything.
