Chainlink crypto project was launched in June 2017 by company SmartContract from San Francisco. LINK was developed on the basis of Ethereum and works on the basis of smart contracts. The creator’s idea is to connect smart contracts through blockchains, giving them access to key resources outside the chain, such as payments on bank accounts, data channels or web APIs. Developers' interest is focused on enabling smart contracts to interact with external systems to make them useful in the business world.
Chainlink coin all-time high price was in February, 2020 when it costed $4.83 USD. Today Chainlink price is 21.494 USD. You can buy Chain Link at Stealthex exchange with a low fee.
