Mempool.space provides a detailed, real-time view of the current state of the Bitcoin network. This information is invaluable for users and developers looking to optimize their transaction timing and performance.

As a result, Leather is tapping into a number of mempool.space API endpoints that allow us to leverage the efficiency and reliability of the network to improve our wallet experience.

GET /api/address/utxo: More Efficient UTXO Management 

This endpoint allows for the query of all Unspent Transaction Outputs (UTXOs) in all Leather wallets. By having this data, Leather can determine the most cost-effective way to send BTC, optimizing transactions and saving on fees. Additionally, we leverage this UTXO information to showcase inscriptions and other Bitcoin assets through our integrated API providers, giving developers a more comprehensive view of wallet contents.

GET /api/address/txs: Faster Transaction Tracking

This endpoint significantly speeds up and optimizes how we display transaction activity. With a single query, devs and users alike can view both pending mempool transactions and confirmed transactions, streamlining their Activity feed in Leather. 

GET /api/v1/fees/recommended: Improved Accuracy for Fee Recommendations

Bitcoin transaction fees can fluctuate unexpectedly, often at the most inconvenient times. Our integration with mempool.space’s reliable fee calculation provides accurate Low, Medium, and High fee recommendations, ensuring that your transactions can be quickly confirmed regardless of urgency. Builders and users can confidently manage transaction fees, balancing cost and speed according to their needs.
