Description
After some investigation, we realised that the problem was caused by a change in gas costs after switching to near protocol version 66. The change relates to the amount of gas used to load contract data, which was changed from 216750 to 1089295 Gas per byte. The change increases the amount of gas used in the
mirror_erc20_token_callbackto approximately to 1TGas. So, more than 5TGas is needed now. Thanks to @birchmd for his help with this investigation.Performance / NEAR gas cost considerations
There are no changes in the performance.
