Fintech provider Portal has raised $34 million in seed funding to support the development of its bitcoin-based decentralized exchange (DEX) and non-custodial wallet. The San Francisco-based firm aims to create a decentralized infrastructure for peer-to-peer swapping of bitcoin across different blockchains without the need for intermediaries such as centralized exchanges or bridges. The funding round includes investments from Coinbase Ventures, Arrington Capital, OKX Ventures, and Gate.io. The success of the funding round reflects the growing interest in bitcoin within the decentralized finance (DeFi) sector.
