Your Gateway To Uncensorable Applications

Portal Defi is a decentralized financial 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. Moreover, transactions are much faster and cheaper than Layer 1 transactions.

Fabric Layer 2

Portal DeFi Apps

Enter the uncensorable internet

We enable peer-to-peer, decentralized, censorship-resistant applications as layers on Bitcoin.

Using Fabric, we enable web scale, serverless infrastructure with strong privacy and security guarantees.

Our Mission is to deliver freedom, one application at a time

Data and Computation Markets

Portal’s layer 2 and layer 3 atomic swap technology can be used for a general purpose market for data and computation. Our goal is to replace the web server model which is prone to centralization by design and architecture with a free market for data and computation. Fabric, the underlying protocol Portal uses extends Bitcoin’s functionality today without needing any BIPs.

Information Markets
Tiny, layer 3 contracts for data stored in a decentralized fashion replace the web server model where the fees provide resistance against censorship of information.
Computation Markets
Users are able to deploy complex programs for blinded execution by a network of peers. Portal swaps pay bonded Bitcoin when “requests for computation” are answered. Contracts assure proof of performance and payment for either party.
