➡️ v3.0.0 Update

Danger

❗️❗️ Automatic upgrade with Cosmovisor ❗️❗️

Before Upgrade Height

➡️ Let’s do it

cd $HOME
wget https://github.com/empe-io/empe-chain-releases/raw/master/v0.3.0/emped_v0.3.0_linux_amd64.tar.gz
tar -xvf emped_v0.3.0_linux_amd64.tar.gz
rm -rf emped_v0.3.0_linux_amd64.tar.gz
chmod +x emped

mkdir -p $HOME/.empe-chain/cosmovisor/upgrades/v0.3.0/bin
mv $HOME/emped $HOME/.empe-chain/cosmovisor/upgrades/v0.3.0/bin

mkdir -p /root/.empe-chain/lib
wget "https://github.com/CosmWasm/wasmvm/releases/download/v1.5.2/libwasmvm.x86_64.so" -O "$HOME/.empe-chain/lib/libwasmvm.x86_64.so"

echo "alias emped='LD_LIBRARY_PATH=/root/.empe-chain/lib:\$LD_LIBRARY_PATH /usr/local/bin/emped'" >> ~/.bashrc
source ~/.bashrc

After Upgrade Height

➡️ Let’s do it

sudo systemctl stop emped

cd $HOME

mkdir -p $HOME/.empe-chain/cosmovisor/upgrades/v0.3.0/bin
mv $HOME/emped $HOME/.empe-chain/cosmovisor/upgrades/v0.3.0/bin
