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

Oracle Provider(s): Specify the oracle(s) used (e.g., Chainlink, Band, API3, TWAP, etc.):

Oracles are not being used.

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

Oracles are not being used. This is a spot CLOB with price discovery occurring on O2 itself. Orders can be placed on O2's books and if matches occur then a trade is settled leading to price discovery of the asset in question.

Documentation/Proof: Provide links to documentation or any other resources that verify the oracle's usage:

N/A

Oracles are not being used. This is a spot CLOB with price discovery occurring on O2 itself

forkedFrom (Does your project originate from another project):

Not Forked

methodology (what is being counted as tvl, how is tvl being calculated):

When signing up to the platform, each user creates a trading account that is a smart contract on the fuel blockchain. they can then bridge assets into it, and the trading account is only allowed to interact with the orderbook contracts. therefore, we calculate the tvl as a sum of all trading account contract balances. we do not include assets that are on the orderbook contract itself as it can fluctuate wildly during high volume periods.

Github org/user (Optional, if your code is open source, we can track activity):

We will be open sourcing contracts soon after mainnet launch
