Harbor Yield
Harbor Yield is Harbor’s planned yield stack on top of stability pools, three participation levels from manual control up to a single pooled hy token per peg.
Work lives in baofinance/harbor-yield. For contract details, see Tech docs, Harbor Yield and Build on Harbor.
Three participation levels
You need ha to use a stability pool. hs is not a pool deposit asset.
Both pool types earn concentrated collateral yield on ha deposits. They differ on rebalance payout: collateral pool → collateral; Sail pool → hs. See Stability Pools and How Yield is Generated.
| Level | What you do | Tokens | Claiming |
|---|---|---|---|
| 1 | Mint ha / hs, deposit ha into a stability pool (Earn), claim yourself | ha earning pool yield | Manual |
| 2 | Deposit ha into that pool’s Compounder | hc… shares over one pool | Automatic |
| 3 | Deposit via a hy vault door → receive hy… | hy… (e.g. hyETH), peg basket share | Automatic (vault) |
- Level 1 is live on Ethereum mainnet.
- Compounders (level 2) and hy (level 3) are siblings, not a stack. One pool + auto-compound → Compounder. Diversified peg yield → hy. Neither wraps the other.
- Each market has two Compounders: one over the collateral pool, one over the Sail pool. hy holds the collateral-pool side. The Sail Compounder stays a level-2 product on its own.
Why it exists
Today (level 1):
- Hold ha (and optionally hs)
- Deposit ha into a collateral or Sail stability pool
- Claim rewards and decide what to do with them. On rebalance, receive collateral or hs depending on pool
Harbor Yield adds:
- Level 2 (Compounder): automatic compounding over one pool, collateral or Sail
- Level 3 (hyTOKEN): one share per peg over collateral-pool positions and peg-equivalent vaults
Harbor Swap is routing support for hy vaults, not a separate yield tier.
How the stack fits together
| Layer | Role |
|---|---|
| Stability pools | Live base, ha deposits earn concentrated yield; rebalance pays collateral vs hs |
| Compounders | Per-pool auto-compound product (level 2) |
| hyTOKEN | Optional peg basket (level 3) |
| Harbor Swap | Routes rewards between basket legs when hy vaults need DEX paths |
Level 1 - Stability pools (live)
Mint ha and/or hs. Deposit only ha into Earn, then claim when you want.
See Stability Pools.
Level 2 - Compounder (mid-term)
Each market deploys two Compounders from the same contract (Compounder_v1). Each wraps one stability pool. Depositors hold hc… shares. Keepers (usually the stability pool manager, on every harvest and rebalance) or users call compound(), which turns pending wrapped collateral into more of that pool.
| Pool | Share | What compound() rolls in |
|---|---|---|
| Collateral | hcXXX.COLn | Harvest and rebalance wrapped collateral, minted back to ha and redeposited |
| Sail | hcXXX.hsCOLn | Harvest wrapped collateral. hs paid on rebalance stays claimable with claim() |
hy holds collateral-pool positions. Sail-pool auto-compound stays on hcXXX.hsCOLn.

Level 3 - hyTOKEN (mid-term)
One hy share per peg (e.g. hyETH) over collateral-pool positions plus peg-equivalent vaults. Enter/exit through vault doors (product UX, not live app yet). Sail-pool exposure stays on the Sail Compounder at level 2.
For builders: hy / ERC-7575 · Harbor Swap.
What users get
| Preference | Level | Use |
|---|---|---|
| Max control | 1 | Earn, deposit ha, claim yourself |
| Auto-compound one pool | 2 | Compounder (when shipped) |
| Simple “earn on this peg” | 3 | hy basket (when shipped) |
Relationship to other yield
- Yield concentration: ha in pools earns from full collateral backing. See How Yield is Generated
- Protocol revenue: Yield Share first, then 75% pools / 25% buy TIDE. See TIDE Tokenomics
- Maiden Voyage Yield Share: Maiden Voyage
Harbor Yield adds convenience and pooling on top; it does not replace those economics.
