Polygon Consumer Contract for LensAPI Oracle

The contracts are copied and revised from https://github.com/Phala-Network/phat-offchain-rollup/tree/main/evm (commit: 7dc2f9bc8917f84c2a855a2df2a2373897dd1b1f).

First you will need to run cp .env.local .env to copy over the local environment variables. The variables are defined as:

• POLYGON_MAINNET_API - API key for Polygon Mainnet RPC endpoint (e.g. Infura, Alchemy).
• POLYGON_MAINNET_SK - Secret Key for the Polygon Mainnet Account that will deploy the Polygon Smart Contract.
• POLYGON_MAINNET_CLIENT_SC - The Polygon Mainnet Client Smart Contract that consumes off-chain data from the LensAPI Oracle.
• POLYGON_MUMBAI_API - API key for Polygon Mumbai Testnet RPC endpoint (e.g. Infura, Alchemy).
• POLYGON_MUMBAI_SK - Secret Key for the Polygon Mumbai Testnet Account that will deploy the Polygon Smart Contract.
• POLYGON_MUMBAI_CLIENT_SC - The Polygon Mumbai Testnet Client Smart Contract that consumes off-chain data from the LensAPI Oracle.
• POLYGONSCAN_API_KEY - Polygonscan API Key that can be generated on polygonscan
• LENSAPI_ORACLE_ENDPOINT - LensAPI Oracle Endpoint Address that can be found in a deployed LensAPI Oracle Blueprint at Phala Mainnet or Phala PoC5 Testnet

Try running some of the following tasks:
