Sie können Metadaten für einen unveränderlichen Smart Contract nicht direkt aktualisieren. Wenn Ihr Smart Contract jedoch das Coin-Modul verwendet und Sie das TreasuryCap erhalten haben, können Sie die update_icon_urlMethode verwenden, um die URL des Coin-Symbols in den Metadaten zu aktualisieren. Dies funktioniert nicht, wenn Sie ein festes Liefer-Token erstellt haben.

Wenn sich die Aktualisierung icon_urlin CoinMetadata nicht sofort auf Explorer wie Suiscan auswirkt, solltest du vielleicht überprüfen, ob es eine Verzögerung gibt oder ob du auf diesen Plattformen eine Aktualisierung auslösen musst. Manchmal spiegelt sich das Update in Wallets mit mehreren Signaturen wider, aber es dauert einige Zeit, bis es auf Explorern erscheint.

Updating a coin logo on a deployed Sui smart contract can be challenging due to the contract's immutability. However, there are potential workarounds to achieve this.

Possible Solutions

• Update Coin Metadata: If the CoinMetadata object was not frozen upon creation, you can use functions like update_icon_url to update the logo URL. This requires having the necessary permissions and access to the TreasuryCap object associated with your coin.
• Create a New Coin: If the metadata is frozen, one option is to create a new coin with the updated logo and migrate users to the new coin. This involves creating a new smart contract with the updated logo and functionality to transfer existing tokens to the new coin.
• Use a Proxy Contract: Although not directly applicable to updating metadata, proxy contracts can be used to implement upgradeable logic in your smart contract. This might involve creating a proxy contract that points to the original contract and updates the logo URL accordingly.

Steps to Update Coin Metadata

1. Verify CoinMetadata Status: Check if the CoinMetadata object is frozen or not. If it's not frozen, you can proceed with updating the logo URL.
2. Use update_icon_url Function: Call the update_icon_url function with the new logo URL to update the coin metadata.
3. Verify the Update: After updating the logo URL, verify that the change is reflected on platforms like SuiScan or SuiVision.

Keep in mind that the specific steps and feasibility of updating a coin logo may vary depending on your smart contract's implementation and the Sui network's policies.
