Signature
Security
Mathematical proof binding a signer to a specific message.
A signature is produced with a private key over a specific message. Others verify it with the matching public key. Always read messages before you sign them.
Frequently asked questions
Which signature schemes are common?
ECDSA on Ethereum and EdDSA on some other chains. Both use public key cryptography.Can I verify a signature offline?
Yes. Tools can check that a signature matches a message and public key without the internet.Why does the message matter?
Signatures prove approval for a specific message. Always read what you are signing.
