PTB Portal to Bitcoin Rank #2586

Portal to Bitcoin, identified by the ticker PTB, is an interoperability protocol designed to connect native Bitcoin assets with broader blockchain ecosystems, including the BNB Chain and Ethereum networks. It functions as cross-chain infrastructure that enables atomic swaps between assets such as BTC, Ordinals, and Runes, as well as Layer 1 and Layer 2 networks, without the need for bridging or token wrapping. The protocol is built around a custody-less architecture, meaning users retain control of their funds throughout the swap process, which the project highlights as a key security feature. By avoiding wrapped representations of assets, Portal aims to preserve the native properties of Bitcoin-based holdings while expanding their usability across multiple chains. PTB also positions itself within the growing BTCfi sector, seeking to bring decentralized finance functionality to Bitcoin-native assets through interoperability rather than custodial or synthetic alternatives.
