Deploy OCR Contract

This Page will provide the information necessary to deploy an OCR Aggregator.

Process Overview:

The below is a high level overview of the process.

In the section after this one, Detailed Contract Deployment Instructions, you'll find links to other pages with in depth details and examples.

• Deploy two SimpleWriteAccessController.sol contracts
  • One will be used as your _BILLINGACCESSCONTROLLER
    • This Contract controls which addresses have the access to update the OCR billing values
  • The other will be used as your _REQUESTERACCESSCONTROLLER
    • This Contract controls which addresses have access to respond to the OCR contract (It whitelists the Nodes)
• Be sure to track which of the contract addresses you'll use for each purpose.
• With the SimpleWtriteAccessController.sol contract deployed, we will then be able to deploy the OCR Aggregator contract., or the AccessControlledOffchainAggregator.sol contract
  • The contract is available, in it's flattened version, here
  • When deploying the AccessControlledOffchainAggregator.sol contract, you'll need to specify the below constructor variables (for details, see the below section)
    • _MAXIMUMGASPRICE
    • _REASONABLEGASPRICE
    • _MICROLINKPERETH
    • _LINKGWEIPEROBSERVATION
    • _LINKGWEIPERTRANSMISSION
    • _LINK
    • _MINANSWER
    • _MAXANSWER
    • _BILLINGACCESSCONTROLLER
    • _REQUESTERACCESSCONTROLLER
    • _DECIMALS
    • DESCRIPTION

• Once you have deployed the AccessControlledOffchainAggregator.sol contract, you'll need to update additional variables to enable the Chainlink Nodes to submit their observations.
  • you can find specific instructions to accomplish this in the section below.
