• If you would like to add a volume 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

Short Description (to be shown on DefiLlama): Filament is a super app for on-chain derivatives, built on Sei’s Parallelised EVM. It ensures high trading and capital efficiency, even in low liquidity situations, by using a hybrid model that combines a Central Limit Order Book (CLOB) and a Compartment-based Pool for order matching.

@rajeebkm thanks for the PR, I have refactored and merged it here: #11735

Correct me if I am wrong, when the users trade, the USDC remain in the same contract right?

Hi @g1nt0ki, thanks for the comment.

Yes, USDC remains in the same contract when users trade. The COMB pool (Compartment-based pool)/vault balance consists of the available funds and the amount borrowed from the pool. If a trade occurs in the pool and, for example, 60% of the trade size is matched with the orderbook while 40% is matched with the COMB pool, this 40% is essentially borrowed from the pool. The available balance in the pool will be reduced by that 40%.

When the position is closed, the pool balance changes based on the realized PnL (Profit and Loss). If the user incurs a loss, the COMB pool gains profit, and the pool balance increases. Conversely, if the user makes a profit, the COMB pool incurs a loss, and the balance decreases.

I hope this clarifies the situation.
