🚀 About MemPush

Project Description

MemPush is a lightweight Flask web application for managing and pushing Bitcoin transactions to the mempool. This tool provides a simple interface to submit raw transactions, track their status, and manually push them to the Bitcoin network.

✨ Key Features:
  • Submit raw Bitcoin transactions
  • Track transaction status (pending, confirmed, failed)
  • Manual transaction pushing to mempool
  • RESTful API for programmatic access
  • Transaction history management
  • Real-time status updates
  • Multi-network support (mainchain, testnetv3, testnetv4, signet)

API Documentation

Note: All API endpoints are network-specific. Replace <network> with one of: mainchain, testnetv3, testnetv4, or signet.
🔌 REST API Endpoints:
GET /<network>/api/transactions

Returns a JSON array of all transactions for the specified network, ordered by creation date (newest first).

Example: curl -X GET http://localhost:5000/mainchain/api/transactions
GET /<network>/api/transaction/<txid>

Returns complete transaction information for a specific transaction ID on the specified network.

Example: curl -X GET http://localhost:5000/mainchain/api/transaction/abc123...
POST /<network>/api/transaction

Submit a transaction ID to fetch and store the transaction from the mempool for the specified network.

Request: {"txid": "your_txid_here"}
Example: curl -X POST http://localhost:5000/mainchain/api/transaction -H "Content-Type: application/json" -d '{"txid": "abc123..."}'
POST /<network>/api/transaction/push

Submit a raw transaction in hex format and push it to the mempool for the specified network.

Request: {"raw_tx": "your_hex_transaction_here"}
Example: curl -X POST http://localhost:5000/testnetv3/api/transaction/push -H "Content-Type: application/json" -d '{"raw_tx": "0100000001..."}'
POST /<network>/transaction/<txid>/push

Push an existing transaction to the mempool for the specified network.

Example: curl -X POST http://localhost:5000/mainchain/transaction/abc123.../push
POST /<network>/transaction/<txid>/delete

Delete a confirmed or failed transaction from the specified network.

Example: curl -X POST http://localhost:5000/mainchain/transaction/abc123.../delete
