AccessControlRegistry Contract Vulnerability Related to OpenZeppelin Dependencies

See the API3 security announcement published on December 10th, 2023 for context. The vulnerability disclosed in this article has been eliminated without ever being exploited, and no user was harmed. On December 6th, Quantstamp informed us that a contract that they have previously audited for API3 was potentially affected by a vulnerability. They refrained from providing more details as the vulnerability applies to contract implementations by other parties as well, but they offered to guide us through a response to it. We informed them that the said contract is not in use yet and no response is required. However, we requested from them to check our AccessControlRegistry implementation for the same vulnerability, as it shared similarities. Our suspicion was confirmed and we addressed the issue across many chains within a few hours, followed by a migration, which ultimately resulted in the elimination of the vulnerability without any loss of funds. We thank Quantstamp for the warning and our users for their swift response. This report is a full disclosure of the specific vulnerability. As disclosed by OpenZeppelin on December 8th, inheriting two components from the OpenZeppelin contracts, ERC2771Context and Multicall, resulted in anyone being able to spoof sender addresses in the inheriting contract. This was patched in v4.9.4, v4.9.5 and v5.0.1, soon after their disclosure. Our AccessControlRegistry implementation was one of t...

How to Use First-Party Data Feeds in Your Smart Contracts

Using API3’s Managed and Self-funded dAPIs in your Solidity Smart Contracts. — It is crucial for dApps interacting with off-chain data to have access to secure oracles. With the coming new ZK chains like Polygon zkEVM and zkSync Era, it is extremely hard to find secure oracles serving off-chain data with complete transparency, especially for major DeFi protocols securing millions in TVL and serving a large user base 24/7. Apart from availability and security, developers have long sought a straightforward, plug-and-play data feed solution for their smart contracts that is easy to integrate and natively supports multiple chains. With these goals in mind, API3 has built a first-party oracle solution that offers secure, transparent, and accurate data feeds on most major EVM chains, while being simple to integrate and use. — Start Using Managed dAPIs in Your Smart Contracts - Connecting smart contracts to price reference data is easy with API3’s decentralized first-party data feeds. Managed dAPIs are data feeds that are sourced directly from multiple first-party oracles and are then aggregated on-chain. They utilize API3’s Airnode, which is a first-party oracle node run by the API provider to serve price data on-chain to DeFi protocols. As a managed service, API3 manages the gas costs and monitoring, which is currently available on 11 EVM-compatible chains. — Getting Started - Head over to the API3 Market ...

    API3, a first-party blockchain oracle solution providing a seamless Web3 wrapper that enables API providers to offer their data directly on-chain, is set to launch its new solution: Amberdata Beacons, in partnership with crypto-asset data provider Amberdata. February 11th-20th's ETHDenver event was chosen as the venue to launch API3’s Beacons, as it remains the largest Web3 hackathon in the world for blockchain enthusiasts, designers, and developers. ETHDenver is community-funded and functions as a platform to provide developers with tools and funding. Introduced in December 2021, API3’s Beacons create a transparent, scalable, and cost-effective solution for data providers to publish data feeds on-chain directly. Beacons represent a unique offering in the ecosystem that is generating excitement among developers and major blockchain protocols alike. “The structure of traditional data feeds conceals where information is sourced, due to a lack of transparency from third-party oracle nodes, ultimately preventing developers from selecting data sources based on their real-world reputations. Beacons improve on this opaque model by harnessing the benefits of first-party oracles, where the data sources feed their data directly on-chain instead of going through 3rd-party intermediaries,” said Heikki Vänttinen, Co-Founder of API3. “Looking ahead, Beacons will be the building blocks of our dAPIs, alongside being offered as a standalone service.” T... read More
