Since Snowbridge has launched and the ERC-20 Wrapped Ether token ([WETH](https://etherscan.io/token/0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2)) has [been registered on AssetHub](https://assethub-polkadot.subscan.io/foreign_assets/f1846f14a52715c2a09df52ef8f077c52977dcfd?tab=holders), set WETH to be a sufficient asset (allow the WETH account to exist without requiring an existential deposit in DOT or another sufficient asset). This ensures a better UX for new users who may not have a DOT balance on AssetHub, even though the Snowbridge UI will warn the user before attempting a transfer without the required existential deposit of a sufficient asset.

Additionally, this referendum sets WETH's metadata to match the metadata on Ethereum:

`{ name: 'Wrapped Ether', symbol: 'WETH', decimals: 18 }`

See [`Pallet::dispatch_whitelisted_call_with_preimage`].

- **Problem Statement:** Allow WETH to be a sufficient asset without needing an existential deposit in DOT for better user experience on Snowbridge for new users.
- **Significance:** Enhances user experience by eliminating the need for a DOT balance on AssetHub for WETH transactions.
- **Proposed Solution:** Set WETH as a sufficient asset and align its metadata with Ethereum's standards.
- **Expected Outcomes:** Improved user experience, seamless WETH transactions, and alignment with Ethereum's metadata standards.
