• Essential Build Tools - sudo apt install build-essential

Build Evmos Node

git clone https://github.com/evmos/evmos && cd evmos
git checkout v11.0.1
make install

Initialize Evmos Node

evmosd init myNode --chain-id evmos_9001-2
wget -O ${HOME}/.evmosd/config/addrbook.json https://files.chaintools.tech/chains/evmos/addrbook.json
wget -O ${HOME}/.evmosd/config/genesis.json https://archive.evmos.org/mainnet/genesis.json

Configure state-sync

SNAP_RPC="https://rpc.evmos.chaintools.tech:443"
SNAP_RPC2="https://rpc.evmos.chaintools.tech:443"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

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