Mixed regime: cash-like sleeves as ballast, directional risk sized off realised volatility, basis capacity capped.
Harbor Key Digital is a Hong Kong-based digital-asset manager founded in 2018. The firm operates licensed-desk infrastructure for digital-asset allocation: segregated client books, documented risk budgets and vault products distributed with a factsheet. On Orbit it runs funding-basis carry, ETH/SOL yield and the Orbit Liquidity Provider vault under Head of Strategies Mira Chen, with risk oversight from Chief Risk Officer David Leung. Reported AUM is US$1.24 billion across listed and digital mandates.
Profile compiled by Orbit from information supplied by the firm; figures are for demonstration, licence and custody wording is illustrative.
Each strategy maps to one vault; deposits are made into a specific vault.
Staked spot versus hedged perp. Yield is the residual after hedge cost — it can be negative.
Trading involves risk. Past performance is not indicative of future results. Vault NAV can rise or fall.
Cash-and-carry when annualized basis clears 8%. Inventory is hedged; residual is funding.
Trading involves risk. Past performance is not indicative of future results. Vault NAV can rise or fall.
Protocol vault. Provides market-making and liquidation liquidity for Orbit; depositors share profits pro rata. No leader profit share.
Trading involves risk. Past performance is not indicative of future results. Vault NAV can rise or fall.
Draft sleeve combining listed and digital risk-on/off. Not live.
Trading involves risk. Past performance is not indicative of future results. Vault NAV can rise or fall.
Funding on BTC remains modestly positive but the 30-day basis has compressed. We are not treating this as a risk-off flag.
Fixed amount caps the dollar risk; fixed ratio inherits the leader's leverage path. Most allocators should start with amount plus a portfolio stop.
BTC funding has printed positive for eleven straight weeks, the longest run since 2024. Carry books across the platform are full. That is the setup in which a single negative print forces everyone to flatten together, so every basis vault on Orbit has a capacity cap and a 24-hour flatten rule.
