Chain specific fields
Overview of supported blockchains that support contract calls and their chain specific details.
address, bool, bytes, bytes1, bytes2, bytes3, bytes4, bytes5, bytes6, bytes7, bytes8, bytes9, bytes10, bytes11, bytes12, bytes13, bytes14, bytes15, bytes16, bytes17, bytes18, bytes19, bytes20, bytes21, bytes22, bytes23, bytes24, bytes25, bytes26, bytes27, bytes28, bytes29, bytes30, bytes31, bytes32, int8, int16, int24, int32, int40, int48, int56, int64, int72, int80, int88, int96, int104, int112, int120, int128, int136, int144, int152, int160, int168, int176, int184, int192, int200, int208, int216, int224, int232, int240, int248, int256, string, uint8, uint16, uint24, uint32, uint40, uint48, uint56, uint64, uint72, uint80, uint88, uint96, uint104, uint112, uint120, uint128, uint136, uint144, uint152, uint160, uint168, uint176, uint184, uint192, uint200, uint208, uint216, uint224, uint232, uint240, uint248, uint256For arrays, please provide the type from above followed by square braces ( ex: uint256[] ). The values for an array must be surrounded with square brackets and delimited with "," (ex. [1,2,3]).
Byte values must be hex-encoded

gasLimit | Gas limit, will be used for the contract call | Integer | 300000 |
gasPrice | Gas price, will be used for the contract call (in WEI) | Integer | 50000000 |

Byte values must be hex-encoded
Field name | Field value | Type | Example |
networkFee | Network fee used for the contract call. By default, 0.1 is used | Number | 0.1 |
systemFee | System fee used for the contract call | Number | 0.1 |
outputs | It is possible to add additional asset transfers together with a contract call by attaching additional outputs. This is a JSON object containing "to", "amount" and "assetId" with json types respectively string, number and string. If "to" is a script hash, it will be translated to a valid NEO address | JSON | { "to": "AKJrLM5Q…", "amount": 1, "assetId": "602c79718…" } |

When executing Hedera transaction you can specify a memo by using a chain specific field
Field name | Field value | Type | Example |
|---|---|---|---|
transactionMemo | A memo that can be used with a transaction | String | "0.0.2810009" |
