sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.0gchain/config/app.toml

# set minimum gas price, enable prometheus and disable indexing
sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0ua0gi"|g' $HOME/.0gchain/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.0gchain/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.0gchain/config/config.toml
