Portal to Bitcoin, a native Bitcoin interoperability protocol, has raised $25 million in a funding round led by JTSA Global. The funds will support the launch of an atomic over-the-counter (OTC) trading desk based on Hashed Timelock Contracts (HTLC). This platform aims to facilitate trustless cross-chain bulk trade settlements. The new OTC market is designed for institutions and large-scale traders, enabling non-custodial exchanges between native Bitcoin and assets on integrated blockchains. By leveraging Bitcoin's Taproot contracts, Portal to Bitcoin seeks to enhance cross-chain trading efficiency and security.
