Maestro's Audited Indexer Unlocks Lending, Stablecoins on the Bitcoin Network

Maestro has released Symphony, the first audited, open-source bitcoin indexer that offers enterprise-grade performance and security for layer two solutions.

Designed for Large-Scale Applications

Bitcoin finance infrastructure provider Maestro has announced the open-source release of an audited bitcoin indexer. Known as Symphony, the indexer is expected to accelerate the development and adoption of sophisticated financial applications, collectively known as BitcoinFi.

According to a media release, Symphony is specifically designed to power large-scale applications capable of processing billions of transactions. It is also fully capable of supporting the most critical Bitcoin metaprotocol standards, like BRC-20s, runes and ordinals. By offering unrestricted access to the Bitcoin indexer on GitHub, Maestro is also empowering builders to push the boundaries of on-chain finance.

“Symphony is the first audited Bitcoin indexer. We’re giving the Bitcoin developer community the same battle-tested infrastructure that powers Maestro’s platform and processes billions of API calls for our clients,” said Marvin Bertin, chief executive officer of Maestro. “Open-sourcing it is our way of giving back to the ecosystem and accelerating the adoption of Bitcoin metaprotocols.”

For developers, startups and enterprises, this release gives them immediate access to a reliable and low-latency data source. This accelerates the deployment of new financial apps, including lending, stablecoins and real-world asset (RWA) tokenization, directly on the Bitcoin network.

Integration with MIDL

A significant highlight of the launch is the integration of Symphony by MIDL, an innovative project that utilizes a smart-contract execution engine to run native EVM decentralized applications (dApps) directly on the Bitcoin network.

MIDL has integrated Symphony into its validator nodes to secure its network at the consensus level. By leveraging Symphony’s block reorganization protection mechanism and its mempool-first indexing, MIDL ensures data integrity and network stability, even when the Bitcoin network faces heavy congestion or chain rollbacks.

Iva Wisher, chief executive officer of MIDL, underscored the importance of this partnership, noting, “Symphony is another major step toward the adoption of Bitcoin, but Maestro’s potential definitely goes far beyond that. And we’re excited to scale the space up together.”

The independent audit by Thesis Defense certifies the security and reliability of the Symphony stack, offering MIDL validators and other layer two solutions (L2s) a highly secure foundation for chain consensus and native metaprotocol validation.
