So I was wanting to use some form of delegation, where a token can be delegated from cold wallet to hot wallet. In my case for a game quest coming up, i'd like to use my NFT for access with out having to remove it completely from my cold wallet. The process for one site i tried seemed like a pretty straight forward process, but i got hung up on the last step to submit transaction for delegation. I'm getting this “Internal JSON-RPC error”. Can anyone enlighten me? Is this something that can be fixed on the metaMask browser wallet side?
