do not return bech32 in receipt, fix 7% fee (#4588)
Browse files Browse the repository at this point in the history
* Fix: max rate issue (#4580)

* fix: max-rate bellow the era min-rate

* fix comments

* add localnet epoch config

* update config

* update config

* update config

* update config

* add log

* remove hip30 from localnet

* disable localnet config

* engine: actually fix the 7% fee implementation

* rpc: fix transaction receipt format for eth

use the same receipt as `hmyv2_`. using a boolean variable, decide if
the addresses need to be converted to bech32. do not return a contract
address unless a contract was actually deployed in the transaction by
using a pointer address type.

* rpc: add comment indicating function is unused

with the switch to `v2.NewReceipt` for even `eth_` queries, the
`eth.NewReceipt` function is no longer used

* build: fix delegation tests

* update comment

blocks was referring to `blocks of code` and not blocks in a chain.
removed the confusing word

* rpc: remove ConvertToEth in GetBlockReceipts

* internal: max rate hard fork schedule

* internal: testnet max rate schedule
