- * outputs: [{name: 'd', type: 'string' }]
- * }]; // contract abi

- *
- * myContract.myMethod('this is test string param for call'); // myMethod call (implicit, default)
- * myContract.call().myMethod('this is test string param for call'); // myMethod call (explicit)
- * myContract.transact().myMethod('this is test string param for transact'); // myMethod transact
- *
- * @param address - address of the contract, which should be called
- * @param desc - abi json description of the contract, which is being created
- * @returns contract object
