ETH Call Task

Suggest Edits

Makes a non-mutating contract call to the specified contract with the specified data payload.

Parameters

  • contract: the address of the contract to call.
  • data: the data to attach to the call (including the function selector).

Outputs

An ABI-encoded byte array containing the return value of the contract function.

Example

encode_call  [type="ethabiencode"
              abi="checkUpkeep(bytes data)"
              data=<{ "data": $(upkeep_data) }>]

call          [type="ethcall"
               contract="0xa36085F69e2889c224210F603D836748e7dC0088"
               data="$(encode_call)"]

decode_result [type="ethabidecode"
               abi="bool upkeepNeeded, bytes performData"
               data="$(call)"]

encode_call -> call -> decode_result
