Set up validator

Official documentation: https://docs.initia.xyz/run-initia-node/running-initia-node/becoming-a-validator

Create a wallet

First of all we will need to create wallet for our validator. You have two options for that.

OPTION 1 - CREATE NEW WALLET

initiad keys add wallet

OPTION 2 - RECOVER EXISTING WALLET

initiad keys add wallet --recover

Save the mnemonic output as this is the only way to recover your validator wallet in case you lose it!

To list your wallets use command below

initiad keys list

Fund a wallet

To create validator you have to fund the previously created wallet using https://faucet.testnet.initia.xyz/

To check wallet balance use command below

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

Create validator

Please make sure you have adjusted moniker, identity, details, website to match your values.

initiad tx mstaking create-validator \
--amount 1000000uinit \
--pubkey $(initiad tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id initiation-1 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.05 \
--from wallet \
--fees 5000uinit \
-y

Save the ~/.initia/config/priv_validator_key.json file as this is the only way to recover your validator signing key in case you lose it!

Set up Oracle

This guide is only for validator nodes

Official documentation: (https://docs.initia.xyz/run-initia-node/running-initia-node/oracle)[https://docs.initia.xyz/run-initia-node/running-initia-node/oracle]

The Slinky Oracle consists of two main elements:

1. An on-chain component that retrieves price data from the sidecar with each block, forwards these prices to the blockchain through vote extensions, and compiles prices from all validators involved.

2. A sidecar process dedicated to polling price information from various providers and delivering this data to the on-chain component.

Step 1: Clone the Repository and build binaries

# Clone repository
cd $HOME
rm -rf slinky
git clone https://github.com/skip-mev/slinky.git
cd slinky
git checkout v0.4.3

# Build binaries
make build

# Move binary to local bin
mv build/slinky /usr/local/bin/
rm -rf build

Step 2: Run oracle

CREATE SYSTEMD SERVICE

sudo tee /etc/systemd/system/slinky.service > /dev/null <<EOF
[Unit]
Description=Initia Slinky Oracle
After=network-online.target

[Service]
User=$USER
ExecStart=$(which slinky) --oracle-config-path $HOME/slinky/config/core/oracle.json --market-map-endpoint 127.0.0.1:17990
Restart=on-failure
RestartSec=30
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

ENABLE AND START SYSTEMD SERVICE

sudo systemctl daemon-reload
sudo systemctl enable slinky.service
sudo systemctl start slinky.service

Step 3: Validating Prices

Upon launching the oracle, you should observe successful price retrieval from the provider sources. Additionally, you have the option to execute the test client script available in the Slinky repository by using the command:

make run-oracle-client

Step 4: Enable Oracle Vote Extension

In order to utilize the Slinky oracle data in the Initia node, the Oracle setting should be enabled in the config/app.toml file.

 ###############################################################################
###                                  Oracle                                 ###
###############################################################################
[oracle]
# Enabled indicates whether the oracle is enabled.
enabled = "true"

# Oracle Address is the URL of the out of process oracle sidecar. This is used to
# connect to the oracle sidecar when the application boots up. Note that the address
# can be modified at any point, but will only take effect after the application is
# restarted. This can be the address of an oracle container running on the same
# machine or a remote machine.
oracle_address = "127.0.0.1:8080"

# Client Timeout is the time that the client is willing to wait for responses from 
# the oracle before timing out.
client_timeout = "500ms"

# MetricsEnabled determines whether oracle metrics are enabled. Specifically
# this enables instrumentation of the oracle client and the interaction between
# the oracle and the app.
metrics_enabled = "false"

Step 5: Check the systemd logs

To check service logs use command below:

journalctl -fu slinky --no-hostname
