A practical guide

A digital signature is a cryptographic proof attached to data. A verifier can use the signer’s public key to check whether the signature matches and whether the signed data has changed. A valid signature shows control of a key under the protocol; it does not automatically prove a person’s identity or make the content safe.It relies on {public-key cryptography|public-key-cryptography}.public-key cryptography

What to know

Wallets may ask users to sign a message or transaction. Read the request carefully: a signature can authorize an action, and unfamiliar prompts deserve caution. Never sign a message just because a stranger claims it is needed for support or a bonus.Review {common phishing tactics|phishing} and {account security|security}.common phishing tacticsaccount security

Using this information

If a game or service offers a signature flow, follow only its official instructions and check the domain. Do not assume a signature is required for UIGame unless the platform itself says so.
