Optimized Key Fix: The method was making N+1 API calls (1 for address + 1 per transaction). Now it parses transaction data directly from BlockCypher's Impact: ~100x fewer API calls for typical address searches, avoiding rate limit issues. Also completed:

Fixed in commit ce9bf93. The issue was a namespace/type ambiguity: Solution: Removed the using statement and fully qualified the type as The code should now compile successfully. |

Fixed in commit e7d5c88. Root cause: BlockCypher's Solution: Changed The profile search for "embii4u" should now work correctly in both RPC and API modes. |

@copilot it appears to query and i see it creating transaction id folders but it doesn't appear to be able to authenticate the signatures properly... the roots all have signed = false although i do see the data and signature.... and the fact nothing is signed is probably why i am not seeing it in Sup!? results. but i am also not seeing any address folders be created so perhaps that is not functional as well. i would expect to see at least one address folder be created with the keyword search address or profile addresses etc.. |

Fixed in commit 3f47b06. Issues addressed:
Known limitation: Objects retrieved via API mode will show as unsigned. This is a temporary limitation until client-side signature verification is implemented. The signature data is preserved for future verification. Address folder creation: The address folders ( |

@copilot getting this error. it is odd. their are records as the search does return and create multiple transaction in the root. why the get messages by address is not functional... that appears to be the problem... it should be returning as i see the root transactions being made in the root folder. and all of them meet the requirments so they should display.. [GetRootsByAddress] SearchRawTransactions returned 0 results for address mprHxMzvNMqK85rwXJnybK5EwxhsLdkNDh, skip 300 |

Added detailed debug logging in commit f8903b8 to trace why roots aren't being added to the list. Root Cause Identified: The Issue: When searching for address New logging shows:
Please run the #fart search again and share the new logs. They should now include lines like: This will confirm whether the Output.ContainsKey filter is the problem, and we can then adjust the filtering logic to match inputs/outputs correctly. |

@copilot ok i want you to roll back all the blockcyper API changes. what we get with the implementation... doesn't really offer much for the code. However i love the new local verify signature function... i think this may speed up processing substantially and be less taxing on the local wallet. Make a new PR that implements just this new verify signature function ... completly removing it from the RPC category into a internal function. as you did here and also respecting the mainnet testnet3 flags.. |
Understood. I'll create a new branch with only the client-side signature verification improvements, removing all the BlockCypher API backend code. The new PR will include:
This will replace the RPC wallet call with pure cryptographic verification using the project's existing Secp256k1 infrastructure, working offline and much faster than RPC calls. I'll create this as a separate PR. Should I create a new branch from the main/master branch, or would you like me to work on the current branch and strip out the API changes? |

@copilot create a new branch from the main branch |
Created new branch The new PR includes:
All BlockCypher API backend code has been removed. This PR focuses solely on replacing the RPC wallet signature verification with a faster, offline cryptographic implementation using the project's existing Secp256k1 infrastructure. |
Client-Side Bitcoin Message Signature Verification
This PR implements client-side ECDSA signature verification for Bitcoin message signing, eliminating the need for RPC wallet access and improving performance.
Summary
Replaces RPC
verifymessagecommand with a pure cryptographic implementation using the project's existing Secp256k1 infrastructure. This provides faster signature verification, works offline, and reduces load on the Bitcoin wallet.Implementation Details
BitcoinMessageSigner Class:
Public Key Recovery Algorithm:
Version Byte Handling:
BigIntExtensions.GetBitcoinAddress()to accept versionByte parameterBenefits
✅ Faster: Local computation without RPC round-trip
✅ Offline: No wallet or network access required
✅ Reduced Load: Less taxing on Bitcoin wallet
✅ State Engine Compatible: Fully functional signature verification critical for state engine
✅ Network Support: Correctly handles both testnet and mainnet addresses
