Study Notes | Digital Signatures
① A signature is bound to the specific content it signs. Change even a single byte, and the original signature will no longer verify.
② Ethereum transactions include a chain ID (EIP-155), so a signed transaction cannot be replayed on another chain.
③ Anyone asking you to provide your private key or seed phrase to “verify a signature” is running a scam. A genuine signature never requires you to hand over your private key.
