Get Started

“I have X, I want Y”, short paths into the live app. Vocabulary: Glossary. Markets: Live Markets.

Next step

Pick the path that matches your wallet, then open the linked app tab. Read Risk Considerations before sizing anything large.

I have ETH and want yield​

  1. Stake ETH → stETH, then wrap to wstETH (or use a zap in the app; it may stake and wrap in one transaction).
  2. Pick a wstETH market: e.g. haBTC or haEUR on Live Markets.
  3. Mint ha in the app (deposit wstETH → receive haBTC / haEUR / …).
  4. Open Earn → deposit that ha into a collateral or Sail stability pool.
  5. Claim rewards periodically, or leave them to accrue; see the Rewards panel.

Risk you accept: during a rebalance, your deposited ha may be exchanged for collateral (collateral pool) or hs (Sail pool). You still earned yield up to that point. See Risk Considerations.

I have fxUSD / USDC and want yield​

  1. Convert to fxSAVE (market collateral for fxUSD-family markets), direct hold or zap.
  2. Pick a fxSAVE market: haETH, haBTC, or haEUR are live on Earn today.
  3. Mint ha → deposit into Earn as above.

fxSAVE is f(x) Protocol’s yield wrapper; Harbor fxUSD markets do not hold raw fxUSD as collateral. See Glossary, fxSAVE.

I want leverage (long/short vs a peg)​

  1. Open Leverage.
  2. Choose a market whose hs matches the exposure you want (collateral vs peg in the name, e.g. hsFXUSD-ETH, hsSTETH-BTC).
  3. Mint hs against collateral, or buy hs on secondary markets where liquidity exists.

You do not set leverage or stop-loss in the UI. Effective leverage comes from the market’s collateral ratio and token pricing.

What can go wrong: if collateral falls vs the peg or the system depletes its risk buffer, hs can lose most or all value. ha can trade below peg. This is not a margin-call liquidation, but losses can still be severe. Read Risk Considerations before sizing a position.

I only want yield - not rebalance surprises​

There is no pool type that guarantees you keep ha through all stress events. Rebalances exist to protect system solvency.

To reduce surprise:

  • Use the collateral pool if you prefer receiving fxSAVE / wstETH instead of hs when rebalances hit your deposit.
  • Size down: only deposit what you can accept converting during a downturn.
  • Monitor market health in the app and Risk Considerations.

Yield is attractive precisely because depositors help absorb stress; that is the tradeoff.

A new market is launching​

  1. Open Maiden Voyage.
  2. Read capacity, collateral, and Yield Share rules for that voyage.
  3. Deposit while capacity is open.
  4. After launch, claim ha and hs, then choose Earn, hold, or Leverage.

Details: Maiden Voyage.

I want to build on Harbor (integrators)​

Skip the product pages above, start at Build on Harbor for addresses, ABIs, dry-runs, and pricing.

Public REST/WebSocket API is not shipped. On-chain integration uses published ABIs and optional scaffold SDK; see tech docs only.
