Mutate all of yours at once
No need to do one RIG at a time. Paste every RIG number you hold and this checks the chain, skips the ones already done, and sends the rest in batches you approve one at a time.
Or type RIG numbers yourself
Unearth your RIG's V3 art
Every RIG carries a finished V3 painting. Unearthing writes that real art to the chain, in place. Your RIG never leaves your wallet, and you only pay the network fee.
Cost: about 2.52M gas.
This page never asks for an approval, a signature on a message, or the words that unlock your wallet. It only asks your wallet to send one transaction that you can read before you sign it.
