kava v0.17 requires changes to app.toml:
|
||||
|
||||
- There are 3 new sections - `evm`, `json-rpc`, `tls`. see the [default app.toml](app.toml)
|
||||
- There is one addition to Base Configuration: `iavl-cache-size`.
|
||||
- It is recommended to add a min gas price for evm txs in `akava` (where 1ukava = 10^12akava). eg `minimum-gas-prices = "0.001ukava;1000000000akava"`
|
||||
|
||||
|
||||
### Coordination
|
||||
|
||||
If the kava-10 chain does not launch by May 25, 2022 at 21:00 UTC, the launch should be considered a failure and validators should refer to the [rollback](./rollback.md) instructions to restart the previous kava-9 chain. In the event of launch failure, coordination will occur in the [Kava discord](https://discord.com/invite/kQzh3Uv).
