As requested by the community.

Registering both Kusama and Polkadot ERC-20 metadata, as well as registering WUD on Kusama.

Just recalled that the Frequency team wants their native asset XRQCY registered and transferable to Ethereum. https://t.me/c/2651825229/216

Could we include this in the PR? Not required, since they can self-register once V2 is ready.
