Knowledge Notes | Digital Signatures
① Every transaction from an Ethereum externally owned account has an incrementing nonce. The same nonce can only be included once, which prevents the same transaction from being executed repeatedly.
② Ethereum transactions include a chain ID (EIP-155), so a signed transaction cannot be replayed on another chain.
③ Before signing, check the action type, the contract address you’re interacting with, and the amount shown in the pop-up. If you don’t understand it, don’t sign yet.
