Accounts and subaccounts
Your Novrinex account establishes ownership. Subaccounts organize how that ownership is used across markets, strategies, and risk boundaries.
This separation lets one owner keep independent pools of collateral and positions without managing a different identity for each one.
Owner account
Section titled “Owner account”The owner address controls deposits, withdrawals, subaccount creation, and trading-key management. Actions with authority over capital remain distinct from ordinary trading permissions.
Signing in proves control of the owner address. It does not move funds or place a trade by itself.
Subaccounts
Section titled “Subaccounts”A subaccount contains its own collateral, open orders, positions, entry prices, and margin reservations. One subaccount cannot use collateral already assigned to another.
A trader might keep market-making capital separate from discretionary positions, or isolate two automated strategies so that their orders and collateral do not overlap. The owner can see and control both while their financial state remains separate.
Each subaccount belongs to one risk domain. Positions can share collateral only when they are compatible with that domain’s rules.
Understanding a balance
Section titled “Understanding a balance”An asset balance is divided according to how the capital can be used.
Available collateral can support a new order or be withdrawn. Locked collateral supports open orders and positions. Pending collateral belongs to a financial transition that has not reached its final state.
These are parts of the recorded balance, not separate hidden accounts. The clearinghouse journals every movement between them.
Trading keys
Section titled “Trading keys”An owner can authorize a separate key for trading. The key may be restricted to particular actions, subaccounts, markets, order sizes, and an expiry height.
A trade-only key can place or cancel orders without receiving withdrawal authority. This reduces the scope of access an application needs, although a compromised trading key can still create losses by changing exposure.
The owner can revoke the key without moving the account to a new address.
Nonces and replay protection
Section titled “Nonces and replay protection”Each accepted action consumes the next nonce for its trading key. A repeated or skipped nonce is rejected, preventing an old signed action from being processed again in a different place.
Request IDs provide a second form of protection at the product level. An exact retry returns the durable receipt for the original action, while conflicting use of the ID fails.
Entering a builder exchange
Section titled “Entering a builder exchange”Builder exchanges operate inside separate risk domains. When a trader enters one, Novrinex creates a dedicated subaccount for that domain under the same owner.
The builder can operate the market and receive its configured fee share, but it does not gain control over the trader’s account or collateral.
