Setup Your Own Aggregators

Let's assume that you are deploying to devnet, you can configure your own private aggregators by being both the admin and the oracle.

Generate a new wallet (if you want):

NETWORK=dev yarn solink new-wallet

info:     address: 9QYPHz91uGZMSueGBhtxmy17L4ynJoWXdTE7mU21kizc
info:     mnemonic: fix toward apology left between video girl novel seminar best sick gap
info:     airdrop 10 SOL {"address":"9QYPHz91uGZMSueGBhtxmy17L4ynJoWXdTE7mU21kizc"}

You .env should contain the followings:

NETWORK=dev

DEPLOY_FILE=deploy.private.json

# 9QYPHz91uGZMSueGBhtxmy17L4ynJoWXdTE7mU21kizc
ADMIN_MNEMONIC="fix toward apology left between video girl novel seminar best sick gap"
ORACLE_MNEMONIC="fix toward apology left between video girl novel seminar best sick gap"

Then copy the setup file:

cp config/setup.private.json.example config/setup.private.json

NOTE: Change the oracle owner key of config/setup.private.json

Finally, run the setup process:

yarn solink setup config/setup.private.json

Redeploy An Aggregator

If successful, the setup process should create the deploy.private.json file that contains all the account addresses associated with the deployment.

If you need to redeploy an aggregator (e.g. btc:usd), remove the corresponding object in aggregators in deploy.private.json, namely:

"btc:usd": {
  "decimals": 2,
  "minSubmissions": 1,
  "maxSubmissions": 3,
  "restartDelay": 0,
  "rewardAmount": 10000,
  "rewardTokenAccount": "3oLHHTaRqNsuTMjsTtkVy8bock6Bx8gCmDxku4TurVj1",
  "oracles": [
    "tester"
  ]
}

Then rerun setup:

yarn solink setup config/setup.private.json

Implement Your PriceFeed

You may need to implement your own price feed to test liquidation. We will support custom feeds in the future... for now edit the code manually.

1. Create an EventEmitter that emits an IPrice

2. Wrap the EventEmitter instance as an async iterator

3. In PriceFeeder change coinbase to your custom price feed
