Transaction decoding is not available for chainId 8453

Support Sending and Receiving Tokens
1

I had a transaction pending for days in BASE which was not visible in blockchain explorer. I tried to cancel the transaction which also did not work. Than I decided to clear the “activity tab data”.

And now I have the problem that I cannot send or mint or whatever on BASE network. I always get the error: “Transaction decoding is not available for chainId 8453”.
If I try to swap tokens at Uniswap or elsewhere I get the error “transaction failed” or “unable to mint”.

Yes, there are funds on BASE network and MetaMask is showing them: 0,0387 ETH and also 16 USDbC.

I don’t know what to do. I tried to start a new Chrome profile and added a new MetaMask extension. Than I added a fresh new BASE network again. I importet my private key into the new wallet but that does not help at all. The error stays the same. No swap, no mint possible. Always with the error: Transaction decoding is not available for chainId 8453.

hi @JakELips , welcome to MetaMask community.
try to use chainlist to change your RPC to see if it works

Thanks. It tried it yesterday several times to change my RPC and it did not work. Today it works without changing my RPC again. All fine again. I have no idea what the problem was.
