Oxygen combines the best centralized solutions for user convenience and Ethereum smart contracts to ensure asset security

A deal is defined as an event when both counterparties are registered by the matching engine and settlement is triggered by the smart contract under following conditions:

• Type and amount of borrowed ERC20 tokens
• Contract expiration date
• Type of tokens used as a collateral
• Interest rate

The lender specifies:

• Asset and its size to be offered to borrowers
• Collateral requirements
• Borrower's minimum credit rating
• Contract maturity date
• Interest rate
• If pooled offers are allowed
• Proposal expiration time

The borrower specifies:

• Asset and its size to be asked from lenders
• Contract maturity date
• Collateral to be settled
• If pooled offers are allowed
• Proposal expiration time

The matching engine has no access to private keys.

Intelligent system provides advisory on market based on market events - ceilings, floors and indicative rates for offer submission.

A set of web applications where participants interact with decentralized repo contracts.

The core of decentralized repo transaction. Security of assets is provided by Ethereum network. The smart contract acts as the settlement mechanism for deals that occurred through the public auction.

The rating system rewards and penalizes users proportionally to the deal’s volumes. A separate smart contract stores the rating data.

Close-out management helps exchange collateral into the original asset of the lender. It can be done either via a decentralized exchange (Etherdelta) or a trusted third-party service (eg Changelly)

System fee is paid in OXG tokens. Gas included.

Loan is transferred to borrower on collateral settlement.

The collateral is locked in the smart contract until the credit-event.

If the borrower fails to return borrowed tokens when the deal has expired, the deal is automatically considered as default. The lender will then be able to claim the collateral from the contract.

When the borrower successfully returns borrowed tokens with interest while the deal is still active (not expired), the deal is automatically considered as completed.

In case of a default the rating declines.

In case of a successfully closed loan the rating increases.

OPTIONAL
If the lender has specified this clause in the contract – automated realization.

Optional. If the lender has specified this clause in the contract the interest is paid from the collateral.

Interest is an agreed percentage of notional value of borrowed assets.

All transactions are secured and the lender will always receive the collateral in case of borrower’s default on payment.

Borrowed assets are returned to the lender via ERC20 contract interface.

The collateral is unblocked from the repo contract and is returned to the borrower.
