PANews reported on December 4th that Portal to Bitcoin, a Bitcoin-native interoperability protocol, announced the completion of a $25 million funding round. The round was led by JTSA Global, with participation from Coinbase Ventures, OKX Ventures, Arrington Capital, and other institutions. Alongside this new funding, the company launched an atomic over-the-counter trading platform, promising "instant, trustless cross-chain settlement for large transactions."

This protocol focuses on providing institutions and large investors with a Bitcoin-pegged cross-chain over-the-counter market. It utilizes Hash Time Locked Contracts (HTLCs) across multiple chains and Bitcoin Taproot contracts to enable the exchange of native Bitcoin with native assets on the integrated blockchain in a non-custodial manner, while emphasizing the reduction of trust assumptions in transactions.
