Setup

• Run the following command to install required packages:

  yarn
  

Test Snapshot

• The snapshot test suite compares results for eth-calls and getStorageAt calls to the provided endpoints.

• Contracts considered:

  • UniswapV2 Factory
  • UniswapV2 Pair
  • USDC
  • Compound
  • Dai / Maker

• Edit the config file:

  Eg:

  blockTag = "0xB5FFFF" # block tag to perform eth-call and getStorageAt call with (eg. block number in hex)
  
  [endpoints]
    endpoint1 = "http://127.0.0.1:8545" # endpoint1 URL
    endpoint2 = "http://127.0.0.1:8082" # endpoint2 URL
  

• Run the following command to run the snapshot test suite:

  yarn test:snapshot
  

Individual Calls

• Run the following to make an eth-call:

  yarn eth-call -e <endpoint> -c <contract> -a <abi> -m <method-name> --method-args [method-args] -b [block-tag]
  

  • endpoint (e): Endpoint to perform eth-call against

  • contract (c): Contract address

  • abi (a): Contract ABI path

  • method-name (m): Contract method to call

  • method-args: Contract method arguments

  • block-tag (b): Block tag to make eth-call with (block number (hex) / block hash)

    Eg.

    yarn eth-call -e http://127.0.0.1:8545 -c 0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f -a abis/UniswapV2Factory.json -m allPairs --method-args 100 -b 0xB5FFFF
    

• Run the following to make a getStorageAt call:

  yarn get-storage-at -e <endpoint> -c <contract> -s <slot> -b [block-tag]
  

  • endpoint (e): Endpoint to perform getStorageAt call against

  • contract (c): Contract address

  • slot (s): Storge slot

  • block-tag (b): Block tag to make getStorageAt call with (block number (hex) / block hash)

    Eg.

    yarn get-storage-at -e http://127.0.0.1:8545 -c 0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f -s 0x1 -b 0xB5FFFF
