Portal

Portal is a trust-minimized, decentralized cross-chain exchange protocol that enables native atomic swaps between Bitcoin and other blockchains without bridges, wrappers, or custodians.

Formerly known as Portal DeFi before rebranding to Portal to Bitcoin in June 2024, the protocol uses Layer 2 Hashed Time-Locked Contracts and a CometBFT proof-of-stake validator network to eliminate intermediary custody risk.

Portal's flagship BitScaler technology scales native Bitcoin for DeFi through non-custodial multi-party channel contracts, enabling permissionless cross-chain transactions without requiring new opcodes on the Bitcoin network.

The Automated Dynamic Market Maker coordinates liquidity across Bitcoin, Ethereum, and Solana for optimal pricing and minimal slippage.

The Portal Wallet is a self-custodial, multi-currency wallet with an integrated cross-chain DEX supporting over 3,000 tokens. Its Swap SDK allows third-party developers to embed atomic swap functionality into existing wallets and DApps.

The RAFA AI co-pilot provides generative intelligence for crypto investment strategies.

Backed by $118M+ in total funding from Coinbase Ventures, Arrington Capital, OKX Ventures, and Paloma Investments, Portal launched its mainnet and $PTB utility token on exchanges including Binance, Bitget, KuCoin, and Kraken in September 2025, recording $800M in trading volume within its first 24 hours.

Founded in 2018 by Dr. Chandra Duggirala, George Burke, and Manoj Duggirala, Portal is headquartered in San Francisco and operates under the legal entity Tides.Network, Inc. with a BVI-incorporated token issuing entity, Chain Cross Ltd.
