Read the EIP-712 domain before signing structured Ethereum data

Read the EIP-712 domain before signing structured Ethereum data

EIP-712 makes structured data available for a wallet to display, but readability does not make a request safe. Domain and message fields must still match the site, chain, contract and action the user intentionally opened.

The standard defines typed structured data, domain separation and eth_signTypedData. It explicitly does not provide replay protection by itself, and implementations decide what humans actually see.

Identify the signing account

Confirm the selected address is the one intentionally associated with the service and not a treasury or savings wallet. A signature can link an address even when no asset moves immediately.

Switching accounts should produce a fresh request with values that can be reviewed again. The specification supports checking domain name, version, chain ID, verifying contract and the full typed message instead of approving an opaque prompt.

Compare the readable name, version, chain ID and verifying contract with official protocol documentation. A familiar domain name string can be paired with an unfamiliar contract. Treat absent fields as missing context rather than filling them from the website artwork.

Read the domain separator fields

Compare the readable name, version, chain ID and verifying contract with official protocol documentation. A familiar domain name string can be paired with an unfamiliar contract.

Treat absent fields as missing context rather than filling them from the website artwork. It cannot prove a contract is benign, guarantee a wallet displays every field, revoke a signature, authenticate SignalBet, prevent every replay or recover assets after misuse.

Determine whether the request is login, order, permit, delegation or another authority-bearing structure. Friendly button text can conceal a permit or transfer authorization. Cancel when the wallet truncates types or nested values that matter.

Inspect the primary type

Determine whether the request is login, order, permit, delegation or another authority-bearing structure. Friendly button text can conceal a permit or transfer authorization.

Cancel when the wallet truncates types or nested values that matter. Reject any typed-data request whose domain, verifying contract, chain, primary type or values differ from the independently verified action.

Check nonces, deadlines, unique identifiers and intended recipient fields in the message. EIP-712 encoding alone does not stop a valid signature from being reused where the application permits it. Prefer short, explicit scope over open-ended authority.

Look for replay boundaries

Check nonces, deadlines, unique identifiers and intended recipient fields in the message. EIP-712 encoding alone does not stop a valid signature from being reused where the application permits it.

Prefer short, explicit scope over open-ended authority. Do not sign a wallet message to unlock a surprise bonus or urgent gambling reward. A no-gas signature can still grant consequential authority.

Save the domain, contract, chain, message summary and time without publishing the signature itself. The signature may function as an authorization token and should not be shared casually. Review connected applications and contract permissions after any suspicious prompt.

What the official source supports

Ethereum Improvement Proposal 712 typed-data standard: The specification supports checking domain name, version, chain ID, verifying contract and the full typed message instead of approving an opaque prompt.

Where the source stops

It cannot prove a contract is benign, guarantee a wallet displays every field, revoke a signature, authenticate SignalBet, prevent every replay or recover assets after misuse.

Make the documented decision

Reject any typed-data request whose domain, verifying contract, chain, primary type or values differ from the independently verified action.

Do not sign a wallet message to unlock a surprise bonus or urgent gambling reward. A no-gas signature can still grant consequential authority.

Run a final evidence review before acting

The standard defines typed structured data, domain separation and eth_signTypedData. It explicitly does not provide replay protection by itself, and implementations decide what humans actually see. Review these checkpoints in order: Identify the signing account; Read the domain separator fields; Inspect the primary type; Look for replay boundaries; Document the approval or rejection. Leave an unanswered item visibly unresolved instead of replacing it with a guess. It cannot prove a contract is benign, guarantee a wallet displays every field, revoke a signature, authenticate SignalBet, prevent every replay or recover assets after misuse.
