LINK / USD AccessControlledOffchainAggregator contract address: 0xDfd03BfC3465107Ce570a0397b247F546a42D0fA

The Access Controlled Offchain Aggregator is the Aggregator contract that each Chainlink Node sends its observations/transmissions to.

This contract is read by the EACAggregatorProxy

Read Calls

This page contains all of the read calls you can make to the AccessControlledOffchainAggregator contracts.

If you'd like to check out the write calls, please check the AccessControlledOffchainAggregator_Writes page.

accessController

The accessController is a smart contract that acts as a whitelist for which addresses are able to call the contract. For the LINK / USD price feed, the referenced accessController smart contract is a null value set to 0x0000000000000000000000000000000000000000

Example Query:
- ACCESS_CONTROLLER=$(curl -s -H "Content-Type: application/json" https://$YOUR_RPC_ENDPOINT -d '{"jsonrpc": "2.0", "id": 123, "method": "eth_call", "params":[{"from":null,"to":"0x2c1d072e956AFFC0D435Cb7AC38EF18d24d9127c","data":"0xbc43cbaf"}, "latest"]}' | jq -r .result) && echo "$ACCESS_CONTROLLER"

Example Response:
- 0x0000000000000000000000000000000000000000000000000000000000000000
  - (remove leading 24 0's)
    - accessController = 0x0000000000000000000000000000000000000000

aggregator

The aggregator is the on-chain contract that each of the Chainlink Nodes responds to. The AggregatorProxy contract points to the configured Aggregator as it's primary source of information

Example Query:
- AGGREGATOR=$(curl -s -H "Content-Type: application/json" https://$YOUR_RPC_ENDPOINT -d '{"jsonrpc": "2.0", "id": 123, "method": "eth_call", "params":[{"from":null,"to":"0x2c1d072e956AFFC0D435Cb7AC38EF18d24d9127c","data":"0x245a7bfc"}, "latest"]}' | jq -r .result) && echo "$AGGREGATOR"

Example Response:
- 0x000000000000000000000000dfd03bfc3465107ce570a0397b247f546a42d0fa
  - (remove leading 24 0's)
    - aggregator = 0xdfd03bfc3465107ce570a0397b247f546a42d0fa
