Harbor uses a few names in the app, on tokens, and in contract code. This page is the user-facing vocabulary. Integrators should also read Token taxonomy.
App actions
| Term | Meaning | App |
|---|
| Earn | Deposit ha into a stability pool to earn concentrated yield | /anchor |
| Leverage | Mint or hold hs for directional exposure (no funding fee, no margin-call UI) | /sail |
| Maiden Voyage | Capacity-capped bootstrap for a new market before or at launch | /genesis |
| TIDE (Tide dashboard) | Token claim / allocation / BAO swap UI | /tide |
Earn and Leverage are the primary labels in docs. “Anchor” and “Sail” are the token families (ha / hs), not interchangeable names for the app tabs.
Tokens
| Symbol | Full name | Role | Examples |
|---|
| ha | Harbor Anchored | Pegged synthetic, tracks a price feed | haETH, haBTC, haEUR |
| hs | Harbor Sail | Residual leverage claim on collateral vs peg | hsFXUSD-ETH, hsSTETH-BTC |
| hy | Harbor Yield (mid-term) | Pooled yield product over several pools per peg, not live on mainnet yet | hyETH, hyUSD (planned) |
Use ha / hs + ticker in prose (haETH, not “HA Tokens” or haTOKENS). Spell out Harbor Anchored / Harbor Sail once per page on first mention if helpful.
Collateral & wrappers
| Term | Meaning |
|---|
| fxSAVE | f(x) Protocol’s yield-bearing wrapper around fxUSD. Harbor fxUSD-family markets hold fxSAVE as wrapped collateral, not raw fxUSD. |
| wstETH | Wrapped staked ETH. Harbor stETH-family markets use wstETH as wrapped collateral. |
| fxUSD | f(x) stablecoin. Often a zap input (fxUSD → fxSAVE); not the token sitting in the minter’s collateral pool. |
Incentives & revenue
| Term | Meaning |
|---|
| Ledger Marks | Off-chain–tracked points from early activity; feed into TIDE programs. |
| Yield Share | Up to ~5% of a market’s revenue for eligible Maiden Voyage participants (carve-out before the global split). |
| TIDE | Harbor governance and value-accrual token (1B hard cap). |
Two ratios (easy to confuse)
| Term | Plain English |
|---|
| Collateral efficiency (mint time) | When you mint, ha + hs together match the value of collateral you put in (subject to fees). You are not minting ha alone 1:1 against all collateral. |
| Collateral ratio (system health) | Collateral value ÷ ha value (e.g. ~130%). When this falls too far, rebalances use stability pools. |

User docs vs tech docs
| User docs | Tech / contracts |
|---|
| ha, hs, Earn, Leverage | peggedToken, leveragedToken, Minter_v2 |
| stability pool | StabilityPool, StabilityPoolManager |
| Maiden Voyage | Genesis_v1 |
| Compounder, hyTOKEN (product names) | ERC-4626 / ERC-7575 interfaces, see Build on Harbor |
Words to avoid in user docs
haTOKENS / hsTOKENS (all-caps plurals), use ha / hs or a concrete ticker.HA Tokens / HS Tokens as headings, use ha (Harbor Anchored) or the ticker.- “Anchor flow” / “Sail flow” without saying Earn / Leverage: link the app tab users actually click.
