wget -O $HOME/.alignedlayer/config/genesis.json https://testnet-files.itrocket.net/alignedlayer/genesis.json
wget -O $HOME/.alignedlayer/config/addrbook.json https://testnet-files.itrocket.net/alignedlayer/addrbook.json

7. Set Seed and Peers:

SEEDS="[e-mail]:50656"
PEERS="[e-mail]:50656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:50656,[email protected]:26656,[email protected]:26656,afeea4cd47aa80504adbdaa8aa019864e291de55@[2a03:cfc0:8000:13::b910:277f]:13356,[email protected]:26656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.alignedlayer/config/config.toml

8. Set custom ports in app.toml:

sed -i.bak -e "s%:1317%:${ALIGNEDLAYER_PORT}317%g;
s%:8080%:${ALIGNEDLAYER_PORT}080%g;
s%:9090%:${ALIGNEDLAYER_PORT}090%g;
s%:9091%:${ALIGNEDLAYER_PORT}091%g;
s%:8545%:${ALIGNEDLAYER_PORT}545%g;
s%:8546%:${ALIGNEDLAYER_PORT}546%g;
s%:6065%:${ALIGNEDLAYER_PORT}065%g" $HOME/.alignedlayer/config/app.toml

9. Set custom ports in config.toml file:

sed -i.bak -e "s%:26658%:${ALIGNEDLAYER_PORT}658%g;
s%:26657%:${ALIGNEDLAYER_PORT}657%g;
s%:6060%:${ALIGNEDLAYER_PORT}060%g;
s%:26656%:${ALIGNEDLAYER_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${ALIGNEDLAYER_PORT}656\"%;
s%:26660%:${ALIGNEDLAYER_PORT}660%g" $HOME/.alignedlayer/config/config.toml

10. Config Pruning:

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.alignedlayer/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.alignedlayer/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.alignedlayer/config/app.toml

11. Set minium gas price, enable prometheus and disable indexing:

sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0.0001stake"|g' $HOME/.alignedlayer/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.alignedlayer/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.alignedlayer/config/config.toml

12. Create Service file

sudo tee /etc/systemd/system/alignedlayerd.service > /dev/null <<EOF
[Unit]
Description=Alignedlayer node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.alignedlayer
ExecStart=$(which alignedlayerd) start --home $HOME/.alignedlayer
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

13. Reset and Download snapshot:

alignedlayerd tendermint unsafe-reset-all --home $HOME/.alignedlayer
if curl -s --head curl https://testnet-files.itrocket.net/alignedlayer/snap_alignedlayer.tar.lz4 | head -n 1 | grep "200" > /dev/null; then
  curl https://testnet-files.itrocket.net/alignedlayer/snap_alignedlayer.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.alignedlayer
    else
  echo no have snap
fi

14. Enable and Start service:

sudo systemctl daemon-reload
sudo systemctl enable alignedlayerd
sudo systemctl restart alignedlayerd && sudo journalctl -u alignedlayerd -f

15. Create Wallet:

alignedlayerd keys add $WALLET

16. Check Balance:

alignedlayerd query bank balances $WALLET_ADDRESS

17. Check sync status:

alignedlayerd status 2>&1 | jq

18. Create Validator:

cd $HOME
# Create validator.json file
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(alignedlayerd comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"1000000stake\",
    \"moniker\": \"test\",
    \"identity\": \"\",

    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json
# Create a validator using the JSON configuration
alignedlayerd tx staking create-validator validator.json \
    --from $WALLET \
    --chain-id alignedlayer \
    --fees 50stake \
