Download Snapshot

Download latest snapshot from our endpoint

wget https://rpc-zero-gravity-testnet.trusted-point.com/latest_snapshot.tar.lz4

Stop the node

sudo systemctl stop evmosd

Reset DB

evmosd tendermint unsafe-reset-all --home $HOME/.evmosd --keep-addr-book

Extract files fromt the arvhive

lz4 -d -c ./latest_snapshot.tar.lz4 | tar -xf - -C $HOME/.evmosd

Re-start the node

sudo systemctl restart evmosd && sudo journalctl -fu evmosd -f -o cat

Check the synchronization status

evmosd status | jq .SyncInfo

Create a wallet for your validator

evmosd keys add wallet

Extract the HEX address to request some tokens from the faucet

echo "0x$(evmosd debug addr $(evmosd keys show $WALLET_NAME -a) | grep hex | awk '{print $3}')"

Request tokens from the faucet

-> FAUCET <-

Check wallet balance

evmosd q bank balances $(evmosd keys show wallet -a)

Note: The faucet gives you 100000000000000000aevmos. To make the validator join the active set you need at least 1000000000000000000aevmos (10 times more)

Create a validator

#set name for your validator
MONIKER=<your_name>

evmosd tx staking create-validator \
  --amount=10000000000000000aevmos \
  --pubkey=$(evmosd tendermint show-validator) \
  --moniker=$MONIKER \
