Announcement

March 03/01/2021 - Portal has merged with Fabric project. Read more about the Fabric project and how it fits into Portal’s mission here

The Financial Internet
Built on Bitcoin

Censorship Resistant Applications

Build unstoppable applications that leverage the security, censorship resistance, liquidity and the largest user base of Bitcoin network.

Decentralized Finance

Asset Swaps, Lending, Borrowing, Staking, Liquidity, Derivatives and other Financial Services built on bitcoin, securely accessible from your wallet.


Cross-Chain Transactions

Using Portal swaps and moving provable execution of these contracts to layer 2, you get the speed and liquidity of centralized alternatives, with the trust minimization guarantees of Bitcoin.

Portal Swaps

Portal swaps is a layer 2 system purpose built to facilitate cross chain atomic transactions. It is like lightning network in that it is layer 2, but unlike lightning which is designed for peer to peer payments, Bridge(swaps) is designed for cross chain atomic exchange.

Portal swaps are the fastest, easiest, most secure and private way to swap your assets and contracts at all times.

Portal non-custodial wallet with cross chain atomic swaps built in

Portal allows peer-to-peer atomic cross-chain transactions with the speed and security of centralized exchanges, but with the privacy and security of underlying blockchains.


Portal supports not just simple exchange but arbitrarily complex financial contracts as well.

Built on Fabric’s
Market for computations

A fee market for De-Fi services

  • Futures, lending, borrowing
  • Vested payments
  • AI price predictions

Built on Fabric

Fabric is a general-purpose "computation market", in which users are able to deploy complex programs for blinded execution by a network of peers. Using cross-chain atomic swaps, digital currency bonded in the initial request for computation assures proof of performance and payment.learn more

Privacy

Recent advances in Fully-Homomorphic Encryption (FHE) have reduced computational requirements to a domain in which real-world users may find tolerable, in the range of 30 seconds to two minutes for small, well-defined programs. Fabric's design relies on Yao's garbled circuits model for Secure Multi-Party Computations.

Layers on Bitcoin

A Fabric lets you spin up your own secure layer two peer-2-peer network using Bitcoin blockchain as the trust anchor. Your peer-2-peer network is secured by Full homomorphic encryption which assures privacy, without requiring another consensus mechanism.

No New Consensus

Why no consensus of our own?: Because we don’t need another “Layer 1 blockchain”. We defer consensus on a global state to an underlying trust anchor, the Nakamoto Consensus of Bitcoin's blockchain.
