Is it possible to sign just ONE transaction, for instance, in the BNB, Polygon, Arbitrum, or Optimism networks, and lose all funds across all EVM networks simultaneously? Or would the threat from a scam transaction/signature only impact funds in the current network?
I'm simply curious to know: if I accidentally sign a scam transaction in an L2 solution or a testnet EVM, could I potentially lose funds in the Mainnet?
