[metabridgelab-web]

Adds metadata and icon for CUBIT on Ethereum Mainnet.

• Network: Ethereum Mainnet (eip155:1)
• Token standard: ERC-20
• Token name: CUBIT
• Symbol: CUBIT
• Decimals: 8
• Contract: 0x2524592CfD16eAb328eE54636259b43a48154A8D
• Official project website: https://www.cubit.im/
• Official CUBIT project page: https://www.cubit.im/cubitcoin
• Etherscan token page: https://etherscan.io/token/0x2524592cfd16eab328ee54636259b43a48154a8d

The official project website has been updated to display the CUBIT Ethereum Mainnet contract address. The project site also documents the CUBIT ecosystem and ERC-20 deployment.

This PR adds a pure SVG vector icon following the repository icon style guidance and metadata pointing to the matching CAIP-19 icon path.

On-chain values used in the metadata:

• name(): CUBIT
• symbol(): CUBIT
• decimals(): 8

Please let us know if any additional verification or formatting changes are required.

Note

Low Risk
Adds static token metadata and an icon only; no application or security-sensitive logic changes.

Hi MetaMask maintainers — I refreshed this PR so the current workflows would run again. Both Test and MetaMask Security Code Scanner are currently in action_required, which indicates they are waiting for maintainer approval for this forked PR rather than reporting a code/test failure. Could a maintainer please approve the workflows to run when convenient? The PR changes only add CUBIT ERC-20 metadata and its SVG icon; no workflow or runtime code is modified. Thank you.
