approve
function approve(address spender, uint256 amount) external nonpayable returns (bool)Sets amount as the allowance of spender over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.

renounceRole
function renounceRole(bytes32 role, address account) external nonpayableRevokes role from the calling account. Roles are often managed via {grantRole} and {revokeRole}: this function's purpose is to provide a mechanism for accounts to lose their privileges if they are compromised (such as when a trusted device is misplaced). If the calling account had been revoked role, emits a {RoleRevoked} event. Requirements: - the caller must be account. May emit a {RoleRevoked} event.
Parameters
role
bytes32
undefined
account
address
undefined
revokeRole
function revokeRole(bytes32 role, address account) external nonpayableRevokes role from account. If account had been granted role, emits a {RoleRevoked} event. Requirements: - the caller must have role's admin role. May emit a {RoleRevoked} event.
