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
