*
* TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
* possible by providing the encoded function call as the `_data` argument to {UpgradeableProxy-constructor}.
*

* the ERC777 and ERC20 interfaces can be safely used when interacting with it.

*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}

// MODIFICATIONS
// Checkpointing logic from Comp.sol has been used with the following modifications:
// - `delegates` is renamed to `_delegates` and is set to private
// - `delegates` is a public function that uses the `_delegates` mapping look-up, but unlike
// Comp.sol, returns the delegator's own address if there is no delegate.
// This avoids the delegator needing to "delegate to self" with an additional transaction
// - `_transferTokens()` is renamed `_beforeTokenTransfer()` and adapted to hook into OpenZeppelin's ERC721 hooks.

// To keep the `dividendOf(_user)` unchanged, we add a correction term:
// `dividendOf(_user) = dividendPerShare * balanceOf(_user) + dividendCorrectionOf(_user)`,

// `dividendCorrectionOf(_user) = dividendPerShare * (old balanceOf(_user)) - (new balanceOf(_user))`.

./full_match/83/0xf80fbb9f77ad646cf66c14873620e33959c65564/sources/contracts/samples/TokenPaymaster.sol | * A sample paymaster that defines itself as a token to pay for gas. The paymaster IS the token to use, since a paymaster cannot use an external contract. Also, the exchange rate has to be fixed, since it can't reference an external Uniswap or other exchange contract. subclass should override "getTokenValueOfEth" to provide actual token exchange rate, settable by the owner. Known Limitation: this paymaster is exploitable when put into a batch with multiple ops (of different accounts): - while a single op can't exploit the paymaster (if postOp fails to withdraw the tokens, the user's op is reverted, and then we know we can withdraw the tokens), multiple ops with different senders (all using this paymaster) in a batch can withdraw funds from 2nd and further ops, forcing the paymaster itself to pay (from its deposit) - Possible workarounds are either use a more complex paymaster scheme (e.g. the DepositPaymaster) or to whitelist the account and the called method ids./calculated cost of the postOp | contract TokenPaymaster is BasePaymaster, ERC20 {
