WalletConnect is the web3 standard for connecting blockchain wallets to dapps. We offer SDKs and infrastructure to provide wallets with more interoperability and a secure connection between a dapp and a wallet.

Worldcoin is a Privacy-Preserving Proof-of-Personhood Protocol (PPPoPP).We’re super excited to give you the first opportunity to build on top of the World ID protocol. Wold ID enables Proof-of-Personhood so that any developer can build anonymous sybil resistant apps.

If you're building something 🔥🔥🔥 on Uniswap - whether it's a tool, swap extensions, governance improvements, or even infrastructure for helping others, UGP wants you to make sure you can build it!

Our current focus is to support specific areas accomplishing the following:

• Usability - improving the user experience
• Community - growing the ecosystem
• Tooling - improving the developer experience

IPFS is a peer-to-peer network and protocol designed to make the web faster, safer, and more open. IPFS upgrades the web to work in a decentralized manner, addressing data by what it is instead of where it’s located on the network or who is hosting it.

Filecoin, the world’s largest decentralized storage network, allows users to store, request, and transfer data via a verifiable marketplace. Filecoin is an entirely open-source alternative to costly cloud storage, where a blockchain network offers efficiently priced and geographically decentralized storage that ensures the persistence of user’s data.

If you would like to get started now and learn about the key concepts behind IPFS and Filecoin, please check our Resources page here. We prepared this content to help you build with them, including developer tools that help you store data on both IPFS and Filecoin quickly and easily.

Polygon is the leading platform for Ethereum scaling and infrastructure development. Its growing suite of products offers developers easy access to all major scaling and infrastructure solutions: L2 solutions (ZK Rollups and Optimistic Rollups), sidechains, hybrid solutions, stand-alone and enterprise chains, data availability solutions, and more.

Superfluid is an asset streaming protocol that enables subscriptions, salaries and rewards to DAOs and crypto-native businesses. It can be used to describe cash flows and execute them automatically on-chain over time in a non-interactive way. Superfluid streams are programmable, composable and modular. The first cash flow types allow constant streams of value and one-to-many distributions. All streams are settled at the same time, based on block timestamps. No capital is locked up, and all inflows and outflows are netted in real time, drastically increasing capital efficiency. A curated suite of developer tools is available, ranging from extensive documentation on the smart contract framework, to SDKs for easy integration (Solidity, Typescript, Redux), to a developer Console to query all needed data during testing and debugging.

Aave Grants DAO is a community-led grants program, focused on growing a thriving ecosystem of contributors within Aave through funding ideas, projects and events that benefit the ecosystem. 

Gearbox Protocol is a generalized leverage protocol: it allows anyone to take leverage in a DeFi-native way and then use it across various DeFi protocols in a composable way. You take leverage with Gearbox and then use it on other protocols you already love. For example, you can leverage trade on Uniswap, leverage farm on Yearn, make complex delta-neutral strategies, get Leverage-as-a-Service for your structured product, and more...

The Graph is an indexing protocol for organising and efficiently accessing data from blockchains and storage networks. The Graph has been running a hosted service since January 2019 with over 2,300 subgraphs deployed for Web3 and DeFi applications built on Ethereum and IPFS, like Synthetix, Uniswap, Aave, Balancer, Gnosis, Aragon, and more.

UMA is a decentralized financial contracts platform built to enable Universal Market Access. Use UMA’s self-enforcing contract design patterns and provably honest oracle mechanism to create your own financial products using standards like ERC20.

Swing is a cross-chain liquidity infrastructure API that lets developers quickly build cross-chain dApps. Swing takes care of underlying infrastructure like multi-chain bridging, liquidity sourcing and routing so that developers can focus on building their application. Swing is built by a team of Silicon Valley engineers from Apple, Amazon, Linkedin and backed by Republic Capital, Arrington Capital, Avalanche, Celer, Bitcoin.com and more.

Swing is the fastest way to integrate cross-chain bridges and multi-chain liquidity into your web3 project.

Connext is the interoperability protocol of L2 Ethereum. Connext enables sending value and calling contracts across Ethereum-compatible chains and L2s, with plug-in support for non-Ethereum systems. Unlike other approaches, the Connext does this without weakening economic security by introducing third party validators - it instead has the same trust considerations as the underlying chain(s). 

Chainlink greatly expands the capabilities of smart contracts by enabling access to real-world data and off-chain computation while maintaining the security and reliability guarantees inherent to blockchain technology. With Price Feeds, Verifiable Randomness, Upkeeps, and making any kind of API call, you can empower your application to do virtually anything.There is an abundance of resources in the Chainlink documentation for any developer at any level to get started.

Fuel Labs is building Fuel, the fastest modular execution layer in the world. We want to encourage creative use of the Sway language to build dapps on Fuel.

Ethereum Push Notification Service (EPNS) is the world’s first decentralized communication & notification protocol for Web3. Using the protocol, any smart contract, dApp or backend can send on-chain or off-chain notifications tied to wallet addresses of a user in a multichain, open, platform agnostic way. Being an open communication middleware, notifs can be integrated and shown on any crypto wallet, mobile apps, extension or dApps.

MakerDAO is an open-source project on the Ethereum blockchain and a Decentralized Autonomous Organization1 created in 2014. The project is managed by people around the world who hold its governance token, MKR. Through a system of scientific governance involving Executive Voting and Governance Polling, MKR holders manage the Maker Protocol and the financial risks of Dai to ensure its stability, transparency, and efficiency. MKR voting weight is proportional to the amount of MKR a voter stakes in the voting contract, DSChief. In other words, the more MKR tokens locked in the contract, the greater the voter’s decision-making power.

Tellor is a transparent and permissionless oracle protocol for your smart contract to easily get any data whenever it needs it.

We at Covalent believe that access to organized blockchain data can unlock a billion possibilities and so we provide the best single unified API to bring full transparency and visibility to assets across all blockchain networks. With the Covalent API, there is no need to invest developer resources in writing SQL or other queries since granular, decoded, multi-chain data is immediately available for 30+ blockchain networks including Ethereum, BSC, Polygon, Fantom and Avalanche. Covalent is fast becoming the go-to data provider, with the Covalent API powering over 1,000 industry-leading projects such as Zerion, ChainGuardians, 0x and Reef.

The Covalent Unified API is the fastest way to get blockchain data for your Chainlink Spring Hackathon project!
