Translate the approval into an outcome

A wallet confirmation is the last place to detect a mismatch between what a page promised and what a transaction can do. If the screen presents only opaque data, the reader cannot meaningfully compare intent with authority.

The Ethereum Foundation announced a 2026 clear-signing initiative aimed at replacing blind approval with human-readable transaction meaning and a shared registry for wallet tooling. Distinguish an automated check, an assessment and a customer conversation. For Write the intended action, preserve action beside asset and do not close the question until recipient is independently checked. Ask for the decision, data source and correction route in plain language.

Write the intended action

The user should be able to state whether the goal is a transfer, token approval, swap or message signature. Describe the expected assets, recipient and maximum authority before opening the wallet. Record the period and definition attached to every threshold. A useful signing-intent worksheet links amount to authority, names the origin of Read the wallet preview and explains why preview is still relevant. The working row is action, asset, recipient, amount and authority; its heading is write the intended action, and its place in the larger record is signing-intent worksheet.

A vague goal such as continue is not enough to evaluate the prompt. Keep affordability evidence private and send it only through an authenticated channel. When asset and authority disagree, retain both observations, recheck Write the intended action and postpone any decision that depends on Read the wallet preview. Describe the expected assets, recipient and maximum authority before opening the wallet. For this write the intended action decision, compare action, asset, recipient, amount and authority with signing-intent worksheet and retain the dated mismatch instead of forcing agreement.

Read the wallet preview

A useful preview should identify meaningful effects rather than only hexadecimal data. Compare every displayed asset movement and permission with the written intent. Keep affordability evidence private and send it only through an authenticated channel. When asset and authority disagree, retain both observations, recheck Write the intended action and postpone any decision that depends on Read the wallet preview. The working row is preview, movement, permission, domain and mismatch; its heading is read the wallet preview, and its place in the larger record is signing-intent worksheet.

Do not approve merely because the originating page looks familiar. Pause spending while an unexpected review is unresolved. The reviewer should reproduce recipient from amount, identify the unit attached to action and see the collection time for preview. Compare every displayed asset movement and permission with the written intent. For this read the wallet preview decision, compare preview, movement, permission, domain and mismatch with signing-intent worksheet and retain the dated mismatch instead of forcing agreement.

Use simulations carefully

A simulation can show likely state changes under a particular chain state. Record the simulation provider, time and assumptions beside its result. Pause spending while an unexpected review is unresolved. The reviewer should reproduce recipient from amount, identify the unit attached to action and see the collection time for preview. The working row is provider, chain state, predicted changes, warning and time; its heading is use simulations carefully, and its place in the larger record is signing-intent worksheet.

A simulation cannot guarantee later execution or eliminate malicious interface risk. Ask for the decision, data source and correction route in plain language. Finish the row by stating who will verify Read the wallet preview, which source governs asset and what change would make authority obsolete. Record the simulation provider, time and assumptions beside its result. For this use simulations carefully decision, compare provider, chain state, predicted changes, warning and time with signing-intent worksheet and retain the dated mismatch instead of forcing agreement.

Check registry provenance

Clear-signing data depends on schemas and metadata that wallets can resolve. Note whether the wallet identifies the application, contract and action source. Ask for the decision, data source and correction route in plain language. Finish the row by stating who will verify Read the wallet preview, which source governs asset and what change would make authority obsolete. The working row is registry, schema, contract, application and verification; its heading is check registry provenance, and its place in the larger record is signing-intent worksheet.

Human-readable text is safer only when its provenance is trustworthy. Distinguish an automated check, an assessment and a customer conversation. For Write the intended action, preserve action beside asset and do not close the question until recipient is independently checked. Note whether the wallet identifies the application, contract and action source. For this check registry provenance decision, compare registry, schema, contract, application and verification with signing-intent worksheet and retain the dated mismatch instead of forcing agreement.

Refuse unexplained authority

Unlimited spending, ownership transfer or an unexpected delegate exceeds many ordinary payment intents. Reject the request and investigate through independently opened sources. Distinguish an automated check, an assessment and a customer conversation. For Write the intended action, preserve action beside asset and do not close the question until recipient is independently checked. The working row is unexpected authority, rejection, evidence, report and next check; its heading is refuse unexplained authority, and its place in the larger record is signing-intent worksheet.

A failed signing attempt should not be retried with broader permission. Record the period and definition attached to every threshold. A useful signing-intent worksheet links amount to authority, names the origin of Read the wallet preview and explains why preview is still relevant. Reject the request and investigate through independently opened sources. For this refuse unexplained authority decision, compare unexpected authority, rejection, evidence, report and next check with signing-intent worksheet and retain the dated mismatch instead of forcing agreement.

Use the Foundation announcement for the 2026 direction

The source explains the security problem clear signing is designed to address and the role of shared standards and registries. The reviewer should reproduce recipient from amount, identify the unit attached to action and see the collection time for preview. Record the period and definition attached to every threshold. Use SignalBet guides only to clarify Write the intended action or action; the named source remains responsible for asset and recipient.

A standard announcement does not prove that a particular wallet, contract or transaction implements the protections correctly. Finish the row by stating who will verify Read the wallet preview, which source governs asset and what change would make authority obsolete. Keep affordability evidence private and send it only through an authenticated channel. That limit keeps amount distinct from authority and prevents Read the wallet preview from being stretched into a claim about preview.

Sign only when meaning and authority agree

The worksheet should connect the reader's intended outcome to the wallet's displayed effects and preserve any mismatch that caused a refusal. A useful signing-intent worksheet links amount to authority, names the origin of Read the wallet preview and explains why preview is still relevant. Pause spending while an unexpected review is unresolved. A completed signing-intent worksheet should leave Write the intended action traceable, recipient bounded and Read the wallet preview ready for its next dated review.

No interface can make a speculative or gambling payment financially safe; use only disposable funds and fixed limits. Adults 18+ who meet local law should treat gambling as optional entertainment rather than income or debt recovery, protect essential money, set cash and time limits before play, never borrow or chase losses, and use the responsible-play centre for blocking, time-out, self-exclusion and confidential support. When asset and authority disagree, retain both observations, recheck Write the intended action and postpone any decision that depends on Read the wallet preview. Ask for the decision, data source and correction route in plain language.
