Smart Contract Deploy Events

Contract deploy events are generated when a transaction involves either the deployment of a smart contract or an upgrade to an existing contract.

Contract deploy event

The contract deploy event is generated upon the successful execution of a transaction that includes the deployment of a smart contract, without encountering any errors.

Structure

Field	Value
identifier	SCDeploy
address	the address of the deployed contract
topics	topics[0] - the address bytes of the deployed contract base64 encoded topics[1] - the address bytes of the deployer of the smart contract base64 encoded topics[2] - the code hash bytes of the deployer smart contract base64 encoded
data	empty

Example

{
    {
        "address": "erd1qqqqqqqqqqqqqpgqnnl9nn0kuuckhg24g02hq2745n4jk2hp327qcay4nm",
        "identifier": "SCDeploy",
        "topics": [
            "AAAAAAAAAAAFAJz+Wc325zFroVVD1XAr1aTrKyrhirw=",
            "NRl7AwoM3hEPC0t9RTDy7gdJUSJvKC5dpJwLYaHLirw=",

        ],
        "data": null
    }
}

Contract upgrade event

The contract upgrade event is generated when a transaction, involving an upgrade, is successfully executed without any errors.

Structure

Field	Value
identifier	SCUpgrade
address	the address of the deployed contract
topics	topics[0] - the address bytes of the upgraded contract base64 encoded topics[1] - the address bytes of the upgrader of the smart contract base64 encoded topics[2] - the code hash bytes of the upgraded smart contract base64 encoded
data	empty

Example

{
    "address": "erd1qqqqqqqqqqqqqpgqnnl9nn0kuuckhg24g02hq2745n4jk2hp327qcay4nm",
    "identifier": "SCUpgrade",
    "topics": [
        "AAAAAAAAAAAFAJz+Wc325zFroVVD1XAr1aTrKyrhirw=",
        "NRl7AwoM3hEPC0t9RTDy7gdJUSJvKC5dpJwLYaHLirw=",
        "kUVJtdwvHG2sCTi9l2uneSONUVonWfgHCK69gdB+52o="
    ],
}

Change owner event

The ChangeOwnerAddress event is generated upon the successful execution of a transaction that specifically involves a ChangeOwnerAddress built-in function call, and this execution must occur without encountering any errors.

Structure

Field	Value
identifier	ChangeOwnerAddress
address	the address of the contract
topics	topics[0] - the address bytes of the new contract owner base64 encoded
data	empty

Example

{
    "address": "erd1qqqqqqqqqqqqqpgqnnl9nn0kuuckhg24g02hq2745n4jk2hp327qcay4nm",
    "identifier": "ChangeOwnerAddress",
    "topics": [
        "UKAg0hORMjk0oT6RalZp1w0Xulvvj0Wa/SSYstBepao="
    ],
    "data": null
