Are BRC100 wallets compatible with legacy BSV wallets?
- Out of the box, many “BRC100-native” wallets are not directly compatible. Bridget notes a BRC100 wallet she inspected “is limiting people to BRC100 native only,” where the UTXO management “requires brc100 wallet payments.”

- However, bridging is possible in practice: she added a function to accept normal BSV payments and then “sweep them into the proper brc100 framework under the hood.” That works, but she calls it “a bit of a hack.”

- Key differences contributing to incompatibility include:
• Different key schemes (BIP32/44 vs BRC-42/43). Assets/keys don’t map 1:1; xpub-based watch patterns don’t carry over directly in BKDS.
• Different UTXO and app-messaging expectations within the BRC100 flow, so “plain” BSV payments may not satisfy the protocol’s assumptions without translation.
