Set up Slinky

This guide is only for validator nodes

Official documentation: https://docs.wardenprotocol.org/operate-a-node/operate-connect

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

# 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/warden-slinky.service > /dev/null <<EOF
[Unit]
Description=W Slinky Oracle
After=network-online.target

[Service]
User=$USER
ExecStart=$(which slinky) --market-map-endpoint 127.0.0.1:17890
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 warden-slinky.service
sudo systemctl start warden-slinky.service

Step 3: 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]
# This option indicates whether the oracle is enabled.
enabled = "true"

# This is the URL of the out-of-process oracle sidecar 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"

# This is the time that the client is willing to wait for responses from
# the oracle before timing out.
client_timeout = "2s"

# This option 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 = "true"

Step 5: Check the systemd logs

To check service logs use command below:

journalctl -fu warden-slinky -o cat

Successfull Log example:

Step 6: Check Slinky oracle prices

To check oracle prices use command below:

curl -s http://localhost:18080/slinky/oracle/v1/prices | jq
