From a transaction logs, how do I decode every logs since I don't have all contracts ABI? Do I have to fetch the ABI every time I encounter an unknown contract?
How do apps that display all logs deal with it? Do they have all existing contracts ABI?
For instance, when I fetch transactions linked to Uniswap Router 2 contract and a specific token I'm watching, there is always some logs I cannot read since they're from an unknown token.
