This example demonstrates how to calculate "Health Factor" of positions of a protocol that is using ERC4626 and deploys new Vaults using a factory.
In this example you learn:
- Tracking newly deployed pool contracts on known factories.
- Using workers to re-calculate position health for each Position every 15 minutes.
1️⃣ Clone this repo:
git clone [email protected]:flair-sdk/examples.git my-indexer
cd aggregate-protocol-fees-in-usd
2️⃣ Install packages and authenticate:
pnpm i
pnpm flair auth
3️⃣ Set the namespace and config.json:
config.dev.json
and config.prod.json
are sample configs for dev
and prod
clusters.
Set a globally unique namespace in each config file (recommended to use {ORG_NAME}-{ENV}
; e.g sushiswap-dev
or sushiswap-prod
) and then run:
# Setting configs for dev testing
cp config.dev.json config.json
# Or setting it for production
cp config.prod.json config.json
4️⃣ Generate manifest.yml and deploy:
pnpm generate-and-deploy
5️⃣ Backfill certain contracts or block ranges:
# Index last recent 10,000 blocks of a contract like this:
pnpm flair backfill --chain 1 --address 0xbD6C7B0d2f68c2b7805d88388319cfB6EcB50eA9 -d backward --max-blocks 10000
Or you can backfill for a specific block number, if you have certain events you wanna test with:
pnpm flair backfill --chain 1 -b 17998797
Or backfill for the recent data in the last X minutes:
pnpm flair backfill --chain 1 --min-timestamp="5 mins ago" -d backward
6️⃣ Look at the logs:
pnpm flair logs --full -tag Level=warn
pnpm flair logs --full -tag TransactionHash=0xXXXXX
pnpm flair logs --full -tag ProcessorId=swap-events
pnpm flair logs --full -tag ProcessorId=swap-events --watch

Q: How do I enable/disable real-time ingestion for indexer?
A: For each indexer defined in config.json
, you can enable/disable it via the enabled: true/false
flag. Remember to run pnpm generate-and-deploy
for the changes to apply on the cluster.
