ERC-7715 permission

ERC-7715 defines a JSON-RPC method, wallet_grantPermissions, that a dapp or agent calls to ask a wallet for a bounded capability instead of a blanket signature: which signer, which actions, which limits, for how long. The wallet shows the user the terms, and if approved returns a permission context the requester can use to execute within those bounds without prompting again.

Enforcement lives in the wallet. MetaMask implements it through its Delegation Framework, where each grant is a delegation with caveat enforcers — contracts that check a limit before an action goes through — attached to a smart account. That is what Sato Hub measures: grants observed on-chain through that framework.

A permission is only as narrow as its caveats. The standard makes limits expressible; it does not require them, and an unbounded grant is a key handover with better UI. It is also a young standard, so the observed counts describe one framework's deployments, not the idea in general.
