• If you would like to add a volume/fees/revenue adapter please submit the PR here.
• If you would like to add a liquidations adapter, please refer to this readme document for details.

1. Once your adapter has been merged, it takes time to show on the UI. If more than 24 hours have passed, please let us know in Discord.
2. Sorry, We no longer accept fetch adapter for new projects, we prefer the tvl to computed from blockchain data, if you have trouble with creating a the adapter, please hop onto our discord, we are happy to assist you.
3. Please fill the form below only if the PR is for listing a new protocol else it can be ignored/replaced with reason/details about the PR
4. For updating listing info It is a different repo, you can find your listing in this file: https://github.com/DefiLlama/defillama-server/blob/master/defi/src/protocols/data2.ts, you can edit it there and put up a PR
5. Do not edit/push package-lock.json file as part of your changes, we use lockfileVersion 2, and most use v1 and using that messes up our CI
6. No need to go to our discord and announce that you've created a PR, we monitor all PRs and will review it asap

Implementation Details: Briefly describe how the oracle is integrated into your project:

Price feeds are polled every minute from the XRC canister. After each poll, the protocol updates its prices, and check for possible liquidation of positions via the liquidation pool.

Yes, protocol is currently not accepting deposits. I will put this PR in draft and un-draft once deposits are accepted.
