Portal is a DeFi platform built on Bitcoin that enables anonymous, zero-knowledge swaps via its cross-chain DEX. It eliminates the need for minting wrapped coins (e.g. wBTC, wETH) or relying on intermediaries for staking. Portal introduces trust-less, bridge-less & wrapper-less cross-chain Atomic swaps across any chain, allowing developers to seamlessly integrate the SDK to their chain or dApps.
