Portal is a defi platform that blends the best of Bitcoin and Layer 2

With Portal, Decentralized finance becomes uncensorable, peer to peer, and trust minimized. Just like the underlying properties of Bitcoin. Portal swaps move provable execution of cross chain contracts to layers 2 and 3, which allows the speed and liquidity of centralized alternatives, with the trust minimization guarantees of Bitcoin.
