# WethGate

> WethGate contract details - fields, functions, and events.

Upgradable contracts cannot receive ether via `transfer` because of increased `SLOAD` gas cost. We use this non-upgradeable contract as the recipient
and then immediately transfer to an upgradable contract. More details about this issue can be found
[here](https://forum.openzeppelin.com/t/openzeppelin-upgradeable-contracts-affected-by-istanbul-hardfork/1616).
