(contract-call contract method)
(contract-call contract method args)
(contract-call contract method args {:keys [:ignore-forward?] :as opts})

Will call a method and execute its smart contract method in the EVM without sending any transaction.

arguments:

contract parameter can be one of:

  • keyword :some-contract
  • tuple of keyword and address [:some-contract 0x1234...]
  • instance SomeContract

method is a :camel_case keyword corresponding to the smart-contract function

args is a vector of arguments for the method

opts is a map of options passed as message data

returns:

function returns a Promise resolving to the result of method call.

Will send a transaction to the smart contract and execute its method.

arguments:

contract parameter can be one of:

  • keyword :some-contract
  • tuple of keyword and address [:some-contract 0x1234...]
  • instance SomeContract

method is a :camel_case keyword corresponding to the smart-contract function

args is a vector of arguments for the method

opts is a map of options passed as message data

Returns:

default: returns a Promise resolving to a tx receipt

This can be configured with :output keyword of opts values: :receipt-or-nil - will return Tx receipt on success, nil in case of revert :receipt-error-pair - returns vector consisting of [tx-receipt error-object] :receipt-or-error - returns single object, Tx receipt in case of success, error-object (js/Error) in case of revert
