Obscuro. Building the most critical part of the Web3 infrastructure

Obscuro is a layer 2 solution that hyper-scales and encrypts Ethereum. Obscuro ensures the inputs, smart contract state and execution are always encrypted all without changing the developer experience or user experience.

Scaling Ethereum
Obscuro combined with ZKP and encryption technology massively scales Ethereum with faster, cheaper transactions while inheriting all of its security and ecosystem benefits.
Transact with any encrypted Ethereum smart contracts. Obscuro provides the entire EVM so every Ethereum application can become an encrypted dApp with no changes.
Developer experience
With Obscuro there are no changes to the Ethereum developer experience. Application developers do not require any specialist knowledge, you can simply port over your Ethereum application. You can continue to use all the great existing Ethereum tooling like Remix, Ganache and Ethers.js.
User experience
There is no change to the end user experience. No need to generate complex ZKPs or change the way you interact with Ethereum applications today. The Ethereum to Obscuro user experience is seamless.
Maximal Extractable Value
Blockchains rely on miners seeing transactions in order to be able to validate them and secure the network. This creates a front-running issue, known as Maximal Extractable Value (MEV) that acts a tax on transactions. On Obscuro, there can only be positive MEV.
With the novel Proof of Block Inclusion (POBI) protocol, assets can be withdrawn back into Ethereum much faster than competing Layer 2s. In addition, the Obscuro network is decentralized from day one. Run by its users, Obscuro is unstoppable, uncensorable and will never go down.



The design of Obscuro allows developers building with the EVM to port over existing dApps without any changes. By deploying your existing EVM-based solution to Obscuro, straight out of the box, you get:

  • smart contract encryption
  • fast transactions
  • significantly lower cost transactions
  • an encrypted version of your dApp
  • The only public element will be your getters which can be made private with one line of code.


    Build new game-changing dApps that leverage encrypted data, encrypted state and confidenfial computing as new primatives. With full encryption you can create fairer DeFi contracts, games with hidden maps, unlock real world assets, all while making use of Solidity and other EVM supported languages and tooling.


    The Obscuro testnet is now live. If you're a developer you can get started immediately using all the existing EVM tooling. If you're a user you can start testing dApps. You'll need to request test OBX from the Discord Faucet.


    use cases

    Encrypted data enables developers to bring more game mechanics on-chain, such as player positions and hidden maps to unlock “fog of war” type games and prevent players from front-running other players' moves. Obscuro's Zero Knowledge Proof technology hyper-scales Ethereum to meet the demands of gaming.
    Private DeFi
    Selecting which data is encrypted enables developers to pick and choose the parts of a DeFi dApp to make private. It might make sense to keep liquidation levels confidential on lending protocols to prevent "liquidation hunting"
    dark pool trading
    A dark pool is a privately organized exchange for trading securities where exposure can be hidden until after execution and reporting. This allows investors to trade without publicly revealing their intentions during the search for a buyer or seller.
    Sealed auctions
    In a sealed bid auction, bidders confidentially submit their one best offer in a sealed envelope. The bids are opened privately by the auctioneer and seller.
    Private agreements
    Agreements, such as a Service Level Agreement (SLA) between a supplier and buyer, are incredibly sensitive. They reveal commercial relationships and impact reputation where an SLA has failed. Agreements deployed to Obscuro can be entirely confidential, such that aside from the participants, nobody even knows the contract exists.
    Solving KYC on blockchain is one of the biggest challenges. Obscuro allows you to build KYC solutions which enable users to only reveal the bits they choose to disclose on demand.


    Encrypted by default
    On the left is Obscuro. All transaction details are fully encrypted by default. No state leaves the enclave in an unencrypted state unless the developer has programmed the dApp to do so. On the right is a standard block explorer with everything out in the open


    Obscuro is a decentralized encryption Layer 2 built on top of Ethereum. Obscuro is designed to enable any Ethereum contract to operate at a larger scale, lower gas, without risk of MEV and crucially, with full encryption. It leverages a technology called Trusted Execution Environments, it's the technology that secures most of your devices.
