Sui package hardening

Fix Sui Security Checks

Freeze mutable capability objects where your wallet owns the relevant Sui object authority.

Fix Sui Security Checks

Connected wallet

Not connected

Connect a Sui wallet to load the coins held by this wallet.

Sui checks

Fix available on-chain checks for objects controlled by the connected wallet.

How it works
1

Select the Sui Coin to audit.

2

Slingzero checks CoinMetadata, TreasuryCap, DenyCap, and UpgradeCap ownership.

3

Fix all available checks in one transaction with the built-in bulk discount.

After confirmation

Slingzero logs the activity, records the fee paid, and redirects you to the Sui manage page for the selected coin.

Each Sui capability is a separate object

CoinMetadata, TreasuryCap, DenyCap, and UpgradeCap do different jobs and can have different owners. The audit reads the objects associated with the selected coin type instead of treating security as one owner flag.

Hardening can remove future options

Freezing or relinquishing a capability can be permanent and may prevent metadata edits, supply changes, deny-list controls, or package upgrades. Apply only the checks you understand after reviewing the exact transaction effects.

About Fix Sui Security Checks

Freeze mutable capability objects where your wallet owns the relevant Sui object authority. Slingzero builds a Sui programmable transaction, keeps capability checks visible, and records the finalized digest for the coin.

Mint Sui Coins

Increase supply with the TreasuryCap controlled by the connected Sui wallet.

Burn Sui Coins

Merge or split owned coin objects and permanently reduce supply through TreasuryCap.

Manage Sui Coins

Review balances, capabilities, supply, safety status, and coin-centric activity.

Still have questions?

Talk to the team

CoinMetadata, TreasuryCap, DenyCap, and UpgradeCap are each separate owned Sui objects. Slingzero only lists and charges for the ones the connected wallet actually controls.

Yes. Open the dedicated tool for that capability, such as Transfer TreasuryCap or Manage DenyCap, if you only want a single check addressed instead of the bulk fix-all flow here.

Nothing. Slingzero only detects and prices checks controlled by the connected wallet, so capabilities owned by other addresses are skipped automatically.

No. Freezing an object or consuming an UpgradeCap through make_immutable is permanent. Review the listed checks carefully before confirming the transaction.
