Inizia dalla riga 714 segnalata di ethereum.ts e segui come CallResult gestisce i risultati eth_call revertiti durante handleTransfer. Usa gli errori JSON-RPC e il backtrace WASM forniti per riprodurre il problema; il lavoro è completato quando i mappings che gestiscono i reverts non si interrompono più accedendo al valore di una chiamata revertita.
