Wallet compatibility

CategoryCompatibilityStatusReviewed / Core wallet tested partial; third-party wallets unknownLast reviewed2026-09-12

Summary

Section titled “Summary”

MoreBC2 now has direct BitcoinII Core v31.1.0 wallet/PSBT runtime evidence in addition to source review, but it still does not have a committed third-party wallet compatibility test record.

Canonical evidence:

BitcoinII Core wallet

Section titled “BitcoinII Core wallet”

Status: Locally tested partial / Source reviewed

Current v31.1.0 Windows testing established that a newly created disposable descriptor wallet could be created, inspected, stopped/reloaded, generate addresses, receive locally mined regtest funds, construct a funded PSBT, sign it, finalize it, and submit the resulting transaction to an isolated local regtest mempool.

The successful PSBT workflow exercised:

  • wallet creation/loading;
  • getnewaddress;
  • local regtest funding;
  • getbalances;
  • walletcreatefundedpsbt;
  • walletprocesspsbt;
  • decodepsbt;
  • finalizepsbt;
  • decoderawtransaction;
  • testmempoolaccept;
  • local-only sendrawtransaction.

This is meaningful wallet compatibility evidence for BitcoinII Core itself. It is not a production-wallet certification and did not use an existing user wallet or public network submission.

Replay-protection implication for wallets

Section titled “Replay-protection implication for wallets”

BitcoinII Core v31.1.0 activates BC2 replay protection on mainnet at height 57750 with fork/domain id 0x01324342.

The release-pinned source trace shows wallet, PSBT, raw-transaction, mempool, block-validation, and signature-hash paths carrying the replay domain. Third-party wallets or external signers that assume ordinary Bitcoin sighash behavior may therefore be incompatible even when they understand Bitcoin-like addresses.

External-signer compatibility after activation remains unverified.

Third-party wallets

Section titled “Third-party wallets”

Status: Unknown / Needs Testing

The repository does not currently establish compatibility for:

  • BlueWallet;
  • Cake Wallet;
  • Komodo Wallet;
  • other third-party mobile, desktop, hardware, web, or external-signer wallets.

Read-only Electrum server reachability does not prove that any wallet can safely define the BC2 network, recognize its genesis/domain rules, display units correctly, build replay-protected transactions, or broadcast them successfully.

Watch-only and Electrum-wallet limitations

Section titled “Watch-only and Electrum-wallet limitations”

Current evidence does not establish:

  • third-party address/scripthash history correctness;
  • xpub/watch-only import behavior;
  • fee display in third-party wallets;
  • ticker/network labeling safety;
  • third-party transaction construction/signing;
  • hardware-wallet signing;
  • replay-protection-aware external signing;
  • Electrum transaction broadcast.

Safe wording

Section titled “Safe wording”

BitcoinII Core v31.1.0 has current MoreBC2 runtime coverage for a disposable wallet and complete isolated PSBT lifecycle. Third-party wallet and hardware/external-signer compatibility remain unverified.

Verification

Section titled “Verification”

Status: Reviewed / Core wallet tested partial; third-party wallets unknown
Primary sources checked: 2026-09-11 v31.1.0 node/wallet and PSBT validation records, release-pinned replay-protection trace, and wallet source-review documentation
Notes: Current evidence supports BitcoinII Core wallet workflows under the documented test conditions only. It does not support recommending an untested third-party wallet.
