Safer Leverage & Real Yield for Every Asset.
Let's be real: synthetic assets sound powerful. But most of them? Clunky, brittle, overly complicated, and definitely not paying your bills.
Harbor changes that.
Harbor is live on Ethereum at app.harborfinance.io. Deposit productive collateral (fxSAVE or wstETH), and the protocol splits it into two tokens:
- ha (Harbor Anchored): pegged to a price feed (e.g. haETH, haBTC, haEUR). Put ha in a stability pool to earn concentrated yield.
- hs (Harbor Sail): variable leverage on collateral vs that peg (e.g. hsFXUSD-ETH). No funding fee, no margin-call UI.
What is fxSAVE? f(x) Protocol’s yield-bearing wrapper around fxUSD. Harbor fxUSD-family markets hold fxSAVE as collateral, not raw fxUSD. See Glossary.

Security & audits
Harbor has a Sherlock Collaborative Audit Report covering bao-base and bao-minter (now Harbor core). Coverage of currently deployed mainnet contracts is partial; some post-audit upgrades shipped after the review, and packages such as zap contracts were out of scope. Harbor Sail is protected from margin-style liquidation, but hs can still lose value (including toward zero) if a market is severely stressed. See Risk Considerations.
Core pieces
ha - pegged (“anchored”)
Synthetic assets pegged to reference prices (ETH, BTC, EUR, …). Redeemable through the protocol. Earn amplified yield by depositing ha into stability pools. Examples: haETH, haBTC, haEUR. See Live Markets.
hs - leverage (“sail”)
Residual claim on collateral vs the peg. Absorbs volatility before ha in stress. Rebalances automatically, not a perpetual with a leverage slider. Examples: hsFXUSD-ETH, hsSTETH-BTC.
Stability pools (Earn)
Two pool types, collateral and Sail, both take ha deposits and earn concentrated yield. They differ in what you receive if a rebalance uses your deposit (collateral vs hs). Stability Pools
