We are excited to announce that we are collaborating with PADO, a cryptography-based infrastructure aiming to bring all Internet data into smart contracts. This collaboration will expand their ZK attestation framework to include on-chain data sources using the power of Brevis!
Brevis Empowers PADO’s Composable Attestations Use Case
PADO harnessed ZK technology to craft proofs attesting the integrity of off-chain Web2 data sources within the Web3 framework while maintaining the privacy of any sensitive portions of that data. Now, with the strategic integration of Brevis, it creates a base for PADO to launch into the realm of attesting Web3 on-chain data directly from the blockchains themselves. All while maintaining the authenticity of that data as well as doing so in a privacy-preserving and trust-free manner.
The initial integration will begin with the Brevis Uniswap Largest Transaction Proof API that is ready for quick and easy implementation.
Brevis provides an effective and efficient approach to verify and store historical Ethereum blocks (please refer to our documentation if you are interested in learning more). By having the Brevis Relayer Network synchronize block headers, one can use the zk-attested on-chain data and the succinct zk-proofs generated by the Prover Network to prove certain transaction information by proving:
- The validity of a block transaction root matches the synced block header info
- The validity of the transaction leaf hash matches the transaction root
In this way Brevis facilitates the efficient verification of one user’s largest Uniswap transaction on Ethereum mainnet during any given time period. The integration of PADO and Brevis will enable users using the PADO plugin to attest their largest Uniswap trading transaction and generate an easily verifiable ZK proof to create their on-chain credit credentials, all in a completely trust-free manner. If you are interested in learning more, you can click here for more information around how PADO and Brevis can be used in various composable attestation use cases using attestations for both on-chain and off-chain data.
Expect More!
However, this is only the beginning. PADO also has plans to integrate Uniswap Sum Trading Volume Proof using Brevis in the near future. Moreover, PADO will be able to expand the different kinds of attested proofs by utilizing Brevis’ Slot Value Proof API and Transaction Receipt Proof API, to enable more verifiable credentials by creating proofs of:
- owning any bluechip NFT
- holding a certain amount of a specific token for a given time period on-chain
- actively interacting with a major Defi/SocialFi/GameFi protocol
- and much more…
We are incredibly excited to see where PADO takes this and cannot wait to collaborate further on new use cases! If you are also interested in building with Brevis we will help you get started! Contact us and get connected with a builder now!
About PADO
PADO is a zkAttestation protocol, dedicated to bring Internet data into web3 smart contracts, expanding the capabilities of smart contracts, and enabling the monetization of personal data within data flows under privacy protection. PADO Labs uses advanced cryptography techniques including secure multi-party computation (MPC) and zero-knowledge proofs (ZKP). In particular, they have rich research and development experience in interactive zero-knowledge proofs (IZK). The cutting-edge IZK protocols enable privacy-related applications to be executed even in a browser extension. This new primitive will be a promising component for building Web3 applications.

About Brevis
Brevis is a smart ZK coprocessor that empowers smart contracts to read the full historical on-chain data from any chain and run customizable computations in a completely trust-free way.
Brevis can trustlessly read the states, transactions, and receipts of any time frame. It efficiently runs computations on data of any size: as the data to prove increases in size, Brevis significantly reduces the per unit cost and time for proof generation. Additionally, Brevis seamlessly verifies Zero-Knowledge (ZK) proofs on any blockchain, providing a unified and trustless user experience for decentralized applications (dApps) operating across multiple chains.
Brevis empowers data-rich use cases including data-driven DeFi, user-segment optimized live-ops features, zkBridges, zkDID, and smart-contract native risk control, all executed in a trustless manner.
