(See also\n * {SafeERC20-safeTransferFrom}).\n *\n * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so\n * contracts should have entry points that don't rely on permit.\n */\ninterface IERC20Permit {\n /**\n * @dev Sets `value` as the allowance of `spender` over ``owner``'s tokens,\n * given ``owner``'s signed approval.\n *\n * IMPORTANT: The same issues {IERC20-approve} has related to transaction\n * ordering also apply here.\n *\n * Emits an {Approval} event.\n *\n * Requirements:\n *\n * - `spender` cannot be the zero address.\n * - `deadline` must be a timestamp in the future.\n * - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner`\n * over the EIP712-formatted function arguments.\n * - the signature must use ``owner``'s current nonce (see {nonces}).\n *\n * For more information on the signature format, see the\n * https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP\n * section].\n *\n * CAUTION: See Security Considerations above.\n */\n function permit(\n address owner,\n address spender,\n uint256 value,\n uint256 deadline,\n uint8 v,\n bytes32 r,\n bytes32 s\n ) external;\n\n /**\n * @dev Returns the current nonce for `owner`.
