Send custom code which is executed off-chain
and have the result is sent back to the contract as bytes32, int256, uint256, string or, bytes.
Private variables, such as API keys, can stored off-chain by uploading them to the Chainlink node's encrypted storage. They can then be used in a request, without being exposed on-chain.
Instead of sending a large string containing custom code, the external adapter can also fetch
before deploying to a contract.
The simulator generates Solidity code which can be pasted into a smart contract.
Also, the web app can be used to easily upload code files via Web3.Storage.
The adapter is available for the Polygon Mumbai testnet through a Chainlink node hosted on Google Cloud Platform.
