Delegate Wallet
The Neo Tokyo ecosystem has implemented the DelegateRegistry protocol. From the Delegate documentation:
delegate.xyz is the best solution to secure valuable onchain assets while still participating in NFT airdrop claims, ERC20 token governance, and more. Users link cold wallets with hot wallets, and then the hot wallet can act on behalf of the cold wallet, like crypto power-of-attorney. Delegating your Citizen wallet will allow you to sign messages on behalf of a secure cold wallet.
