At least one Umbrasync instance has been patched to work-around invalid transactions being included in the monad blockchain. Prod as returned as a result.

Monad seems to have unintentionally added a feature where invalid transactions, that is, transactions which are 100% guaranteed to fail, are added to the chain. This include things like sending more MON than you actually have in your account. The transaction gets reverted, but our block scraper couldn't cope with transactions that should never be attempted to be processed in the first place actually being in the ledger.

We're working on solutions on these edge-cases and will be up ASAP.
