Deploy the DependencyAudit contract and upgrade the service account

[janezpodhostnik]

Overview

The dependency audit contract is responsible for emitting an event whenever there are any unstated dependencies (contracts) used in a transaction https://github.com/onflow/contract-updater/blob/main/contracts/DependencyAudit.cdc.

To use it the DependencyAudit contract has to be deployed to the service account, and the service account contract needs to be updated to include a call to the dependency audit contract: https://github.com/onflow/flow-core-contracts/pull/430

1. Deploy DependencyAudit

• New contract deployment
• code: https://github.com/onflow/contract-updater/blob/698a7fd66446feb842f25e4d22d7f841a0692779/contracts/DependencyAudit.cdc
• PR: https://github.com/onflow/contract-updater/pull/33
• destination address: Service account
• deploy parameters:

    {
        "type": "Array",
        "value": [
            {
                "type": "Address",
                "value": "0x8624b52f9ddcd04a"
            },

            },
            {

                "value": "0x1654653399040a61"
            },
            {

                "value": "0x1d7e57aa55817448"
            },
            {
                "type": "Address",
                "value": "0xb19436aae4d94622"
            },
            {

                "value": "0x220c1b4155f86f2f"
            }
        ]

[!NOTE]
These will be the addresses that are skipped when checking which dependencies are staged or not

2. Update FlowServiceAccount

• updating the existing contract
• code: https://github.com/onflow/flow-core-contracts/blob/janez/dependency-audit/contracts/FlowServiceAccount.cdc
• PR: https://github.com/onflow/flow-core-contracts/pull/430
• destination address: Service account

• diff: With the currently deployed contract
