How to update coin logo on Sui smart contract?

Question

Im trying to update the coin logo on a deployed smart contract on SuiCoins.com, but Ive hit a roadblock because the contract is immutable. Are there any possible workarounds or methods like using proxy contracts or implementation contracts to change the logo so it reflects on platforms like suiscan or suivision?

Michelle · Accepted Answer

You cant directly update metadata for an immutable smart contract. However, if your smart contract uses the coin module and youve been given the TreasuryCap, you can use the update_icon_url method to update the URL of the coins icon in the metadata. This wont work if youve created a fixed supply token .

If updating icon_url in CoinMetadata doesnt reflect immediately on explorers like suiscan, you might want to check if theres a delay or if you need to trigger a refresh on these platforms. Sometimes the update reflects in multisignature wallets but takes time to appear on explorers .

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

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.
Use update_icon_url Function: Call the update_icon_url function with the new logo URL to update the coin metadata.
Verify the Update: After updating the logo URL, verify that the change is reflected on platforms like SuiScan or SuiVision.
