Portal to Bitcoin, a Bitcoin-native interoperability protocol, has successfully raised $25 million in a funding round led by JTSA Global. The round saw participation from notable investors including Coinbase Ventures, OKX Ventures, and Arrington Capital. In conjunction with the funding announcement, Portal to Bitcoin introduced an atomic over-the-counter (OTC) trading platform. This platform offers instant, trustless cross-chain settlement for large transactions, targeting institutions and large investors. The protocol employs Hash Time Locked Contracts (HTLCs) and Bitcoin Taproot contracts to facilitate non-custodial exchanges of native Bitcoin with assets on integrated blockchains, aiming to minimize trust assumptions in transactions.
