The Avalanche avalanche protocol is committed to integrating market-leading smart contract infrastructure to provide stronger support for the growing developer community. To this end, in July 2021, Chainlink Price Feeds will integrate Avalanche to provide high-quality price data for various DeFi applications. Today, we are very excited to announce that Chainlink Keepers and Chainlink VRF are live on the Avalanche mainnet, providing a richer resource for applications in the Avalanche ecosystem.
Starting today, Chainlink Keepers and Chainlink VRF will bring more convenience to Avalanche developers and users.
Simply put, the automated execution of smart contracts simplifies the DeFi experience. Many smart contract functions can be performed automatically, such as liquidating undercollateralized loans, executing limit orders, and claiming machine gun pool profits.
Using Chainlink Keepers (see link 1 at the end of the article), developers can build use cases for automatic execution of smart contracts without relying on a centralized server. If you wish to integrate Chainlink Keepers into your project. Please refer to the Chainlink developer documentation (see link 2 at the end of the article) and submit a task delegation to Keepers (see link 3 at the end of the article).
Chainlink VRF provides developers with a highly secure and transparent random number generator. With the advent of a large number of new features, Chainlink VRF will provide developers with a configurable, scalable, and cost-effective random number solution. If you wish to integrate Chainlink VRF into your project, please join the Chainlink Discord and consult the developer documentation (see link 4 at the end of the article).
How Avalanche Developers Leverage Chainlink Keepers
Chainlink Keepers is a decentralized automatic transaction execution service. Developers can customize trigger conditions and set the automatic execution of smart contracts. Developers pre-set conditions, and Chainlink Keepers will continuously monitor whether the pre-set conditions are met. Once satisfied, Keepers will automatically send on-chain transactions, executing smart contracts. Notably, Chainlink Keepers and Chainlink Price Feeds use the same batch of tamper-resistant, Sybil-resistant nodes that maintain the security of tens of billions of assets.
Outsourcing DevOps tasks to Chainlink Keepers means developers can build more advanced, feature-rich applications with complete automation and decentralization. At the same time, Keepers provide a lot of design space. Tasks and functions such as DEX limit orders, automatic receipt and reinvestment of income, start and stop of chain games, dynamic NFT, and automatic execution of DAOs can all be realized through Keepers. Get more inspiration by reading the overview of Chainlink Keepers smart contract automation use cases.
The integration of Chainlink Keepers empowers Avalanche developers to ensure time-to-live and secure smart contract DevOps tasks in new ways, while reducing workload, rolling out advanced features, shortening app development cycles, and simplifying the user experience.
Chainlink Keepers monitor automated execution logic in a secure and low-cost off-chain manner through a decentralized network. If the preset conditions are met, the on-chain transaction is sent and the smart contract is executed. Chainlink unlocks a range of new use cases through secure off-chain computing, making Web3 development as smooth as Web2.
“Chainlink’s trust minimization service is critical to Web3 gaming projects. The automatic execution of smart contracts provided by Chainlink Keepers not only saves the development team’s precious time, but also makes the user experience smoother. The tamper-resistant random numbers provided by Chainlink VRF are It increases players’ confidence in the fairness of the game.”
—Oxtender, co-founder of Crabada
“We chose Chainlink Keepers because it is the most secure and reliable smart contract automatic execution solution in the blockchain field. Chainlink Keepers saves valuable time for the development team and improves the efficiency of the protocol.”
——LB, founder of Grape Finance
How Avalanche Developers Leverage Chainlink VRF
Avalanche developers can now integrate Chainlink VRF to use verifiable random numbers in their applications, ensuring the security of NFT minting, fairness of game results, randomness of governance participants, and others in the fields of DeFi, NFT, DAO, etc. Example. For an in-depth look at Chainlink VRF, check out Chainlink VRF’s 35+ Blockchain Random Number Generator Use Cases.
Chainlink VRF facilitates developers in the following ways:
• Cost-effective random number request – Chainlink VRF has launched a subscription management application: the development team only needs to register a subscription account and recharge to pay the cost of random number request for multiple smart contract applications. Single account, unified management, no need to recharge each application separately.
• The upper limit of the callback gas can be set by yourself – Chainlink VRF allows users to set the callback gas fee up to 2.5M. In this way, complex smart contract logic can also be executed at one time, outputting verifiable random numbers, and even when the network is congested, important tasks that require random numbers can be successfully performed.
• Multiple random numbers can be output in a single request – Chainlink VRF’s verifiable random function coordination contract allows users to request multiple random numbers at one time. These random numbers are also generated once, which can reduce cost and response delay.
• Multiple addresses can share the same subscription account – the same account and the same balance can be used to pay for random number requests for up to 100 smart contracts. This not only reduces gas costs, but also simplifies the process of managing funds for development teams running multiple smart contracts.
“Chainlink VRF enables Trader Joe to achieve fairness and verifiable batch generation on the NFT launch platform. Chainlink VRF can output multiple random numbers for a single request and verify these random numbers on-chain, which will reduce the gas cost of launching NFTs and improve safety.”
– Fish, co-founder of Trader Joe
“PoolTogether utilizes Chainlink VRF to select the winners of the V3, V4 pools. As a lossless lottery game, Chainlink VRF provides us with verifiable fairness guarantees with unparalleled transparency and security.”
– Brendan Asselstine, CTO, PoolTogether
“The launch of Chainlink Keepers and Chainlink VRF is a milestone for Avalanche developers. These two services will both simplify the development and user experience, and drive innovation in Dapp design and functionality. The Avalanche community has a large number of tireless Excellent developers, with Chainlink Keepers and Chainlink VRF, it will be even more powerful to quickly build and launch large-scale applications.”
—Emin Gün Sirer, founder and CEO of Ava Labs
“I am very pleased that Chainlink Keepers and Chainlink VRF can natively integrate the Avalanche ecosystem, and support Avalanche developers to create a new generation of hybrid smart contract applications that achieve end-to-end automatic execution and secure access to verifiable random numbers. Chainlink Keepers can improve security, Guaranteed service launch time, Chainlink VRF v2 has excellent scalability and cost-effectiveness, and they will further empower Avalanche developers to explore the infinite possibilities of Web3.”
— Sergey Nazarov, co-founder of Chainlink
Chainlink establishes the industry standard for the development, access and sale of oracle services for hybrid smart contracts on any blockchain. The Chainlink oracle network can reliably connect smart contracts to any external API and securely perform off-chain computations, enabling rich functionality for applications. Chainlink currently secures tens of billions of dollars in assets for major industries such as DeFi, insurance, and gaming, and provides a common portal for global enterprises and leading data providers, with one-stop access to all blockchains.
