Example of a decentralized crop insurance insurance product that makes using of Chainlink Oracles to obtain external data from multiple weather APIs
Please refer to the technical article on the Chainlink official blog
The contracts can be deployed to Kovan either via this Remix link, or via Truffle commands below.
You'll need a MNEMONIC and a kovan KOVAN_RPC_URL environment variable. Your MNEMONIC is your seed phrase of your wallet. You can find a KOVAN_RPC_URL from node provider services like Infura
Then, either set them in a bash_profile file or export them into your terminal like:
export MNEMONIC='cat dog frog....'
export KOVAN_RPC_URL='www.infura.io/abcdefg'# install packages.
npm install
# compile contract
truffle complie
# migrate contract
# First update truffle-config.js to contain correct key information for your wallet and infura provider
truffle deploy --reset --network kovan
Once the contract is deployed and you have the master contract address. You need to fund it with some ETH and LINK to be used in the creation of insurance contracts. Once that's done, you can then interact with the InsuranceContracts functions via any Contract interaction method, such as MyEtherWallet
