Add minium gas prices into app.toml

Terminal window
minimum-gas-prices = "0.025ukava;1000000000akava"

Do the rest of the port configuration as desired; The EVM configuration and ports can be found in the app.toml under ection “EVM Configuration”

For the purposes of Axelar, Kava RPC nodes can be kept fully pruned. Update the pruning config in $HOME/.kava/config/app.toml as below

pruning="everything"

Create a state sync script statesync.sh with the following code and replace the RPC var for the appropriate network.

Terminal window
https://kava-mainnet.chainode.tech:443
Terminal window
https://kava-testnet.chainode.tech:443
 
#!/bin/bash


RPC="RPC"


LATEST_HEIGHT=$(curl -s $RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)


sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \

s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.kava/config/config.toml

Run the script with appropriate permissions.
