[The Service Account smart contract](https://www.flowdiver.io/contract/A.e467b9dd11fa00df.FlowServiceAccount?tab=deployments) on mainnet will be updated next week on Tuesday, June 11th by the service account committee.

The update will add the checkDependencies function to the contract in preparation for the [Cadence 1.0 launch](https://flow.com/upgrade/crescendo/cadence-1) to allow tracking of contracts which have not yet been staged for upgrade.
