Bluefin

Bluefin offers multiple earning surfaces (Pools, Lend, Vaults, Perps), but only Pools display explicit swap fee tiers and realized fee generation in the UI.

Pools (spot AMM) — explicit fee tiers

Pool swap fees are set per pool and accrue to liquidity providers (LPs) as trading fees; Bluefin shows 24h Fees and an annualized 24h APR.

Examples of fee tiers shown:

• SUI/USDC: 0.175% fee tier (TVL $6.18M, 24h fees $9,516.79, 24h APR 67.52%)
• suiUSDe: 0.01% fee tier (TVL $423.04K, 24h fees $85.44, 24h APR 26.79%)
• suiUSDT: 0.001% fee tier (TVL $2.16M, 24h fees $61.42, 24h APR 8.50%)
• BLUE: 0.25% fee tier (TVL $34.61K, 24h fees $104.97, 24h APR 110.71%)

Protocol take / revenue share (not disclosed)

Bluefin does not display an LP vs protocol split (no “protocol fee” toggle or %). As a result:

• LP share %: not disclosed
• Protocol take rate: not disclosed
• Fee capture ratio (protocol revenue / gross fees): not computable from the UI

Platform-level scale context

Bluefin shows Total TVL: $116.99M and All-time volume: $104.07B, which supports the premise that fee-driven strategies can be meaningful when routed flow is strong—however, earnings visibility is best on the Pools screen (per-pool fees + APR).

Bluefin Pools show per-pool TVL, 24h volume, 24h fees, and an annualized 24h APR. Below are the most actionable pools by a mix of yield and TVL (risk-adjusted: preference to deeper liquidity unless yield is exceptionally high).

Notes: “Base APY” below is the displayed fee-based annualization (24h APR). “Reward APY” and “30d Avg APY” are not displayed, so they are marked N/A.

Strategy notes (by risk profile)

• Conservative LPs: prioritize stablecoin-heavy pools where price divergence is smaller (e.g., suiUSDT, suiUSDe). Even with lower fee tiers (0.001%–0.01%), the displayed APRs can still be meaningful when volume is high.
• Balanced LPs: the deepest “core” route pool is SUI/USDC with $6.18M TVL and $9,516.79 in 24h fees (displayed 67.52% 24h APR). Expect IL if SUI trends.
• Aggressive LPs: smaller TVL pools with very high displayed APR (e.g., BLUE at 110.71%) can be lucrative but are typically far more sensitive to IL, liquidity gaps, and fast APR mean-reversion.

Practical caution: these APRs are explicitly 24h-annualized, so they can swing sharply day-to-day with volume spikes.

Bluefin’s clearest “set-and-forget” income stream is lending supply APR (rather than classic single-token staking/ve-locks). The Lend screen shows Supply APR, Borrow APR, total supply, and total borrow per market—enabling passive yield without LP impermanent loss.

Notable supply APRs (examples)

• WAL: 37.36% supply APR (total supply $3.33M, total borrow $1.86M)
• USDSUI: 18.00% supply APR (total supply $4.06M, total borrow $894.19K)
• DEEP: 13.80% supply APR (total supply $5.14M, total borrow $2.36M)
• eWAL: 19.71% supply APR (total supply $244.53K, total borrow $19.71K)
• egUSDC: 11.61% supply APR (total supply $2.71M, total borrow $12.46K)
• USDC: 5.41% supply APR (total supply $41.51M, total borrow $28.96M)
• stSUI: 3.17% supply APR (total supply $7.13M, total borrow $1.16M)

Borrowing parameters are explicit

Markets include maximum LTVs on certain assets (example shown: eTHIRD Borrow LTV 80.00), which matters for leveraged looping strategies—but also introduces liquidation risk.

What’s not shown as a staking product

There is no explicit veToken/lock duration, validator staking module, or “stake BLUE for protocol fees” mechanic visible in the UI sections provided. If you want passive yield on Bluefin today, the most transparent path is supplying to lending markets (variable APR) or using vaults (covered separately).

Bluefin’s incentives are presented more as productized yield (vault APYs, lending APRs) and pool categorization rather than a clearly published “liquidity mining schedule” with token emissions.

Evidence of incentive surfaces in-product

• Pools UI includes “Incentivized” and “Verified” filters, indicating certain pools may receive special treatment or incentives beyond base swap fees. However, no emission rate, token, or end-date is displayed alongside the pool rows.
• Perps UI includes a dedicated “Rewards” tab (visible in the trading interface). The tab presence signals a rewards program for active traders, but the reward formula, eligibility, and payout asset are not shown in the extracted interface text.
• Vaults show explicit APYs and are “Powered by Ember Protocol” with a dashboard showing scale metrics: Total Deposits $68.55M, Total Earnings $2.17M, Depositors 40.69K. This is a strong, quantifiable incentive to route capital into managed strategies rather than manual farming.
• “AlphaFi x Bluefin Collaboration” appears under Lend (“Other Markets”), implying ecosystem incentive partnerships exist, but no numeric reward add-on is displayed.

What you should assume (and what you shouldn’t)

• You can reliably count on displayed APR/APY numbers (pool 24h APR, lending supply APR, vault APY) as the only quantified “reward” data.
• You should not assume extra token rewards unless the specific pool/vault explicitly shows them; the UI here does not provide emission breakdowns.

Bottom line: incentives exist, but disclosure is uneven—best quantified on Vaults and Lend, less explicit on Pools and Perps.

Below are concrete playbooks using only strategies with visible yields on Bluefin.

🛡️ Conservative (capital preservation)

1) Ember Earn Vault (USDC) at 9.52% APY (TVL $4.73M). Treat this as a core allocation for hands-off yield.
2) Park additional reserves in USDC lending at 5.41% supply APR (supply $41.51M, borrow $28.96M) to avoid LP IL.
3) If you prefer LP fees over lending, use stablecoin-heavy pools like suiUSDT (displayed 8.50% 24h APR, TVL $2.16M), understanding APR is 24h-annualized.
Expected range: ~5%–10% (higher if 24h APR persists; it often won’t).

⚖️ Balanced (moderate risk/reward)

1) LP SUI/USDC (fee tier 0.175%) with $6.18M TVL and $9,516.79 24h fees (displayed 67.52% 24h APR). Size modestly due to IL on SUI.
2) Add a lending sleeve like DEEP at 13.80% supply APR (supply $5.14M, borrow $2.36M) or egUSDC at 11.61%.
3) Consider the Concentrated Liquidity Vault at 13.26% APY (TVL $1.52M) if you want managed LP without manual rebalancing.
Expected range: ~10%–25% (can spike higher due to fee bursts/24h APR).

🔥 Aggressive (max yield focus)

1) Target high headline supply APR like WAL at 37.36% (supply $3.33M).
2) Farm smaller, high-APR pools (e.g., BLUE pool displayed 110.71% 24h APR, TVL $34.61K) but cap position size due to liquidity/IL risk.
3) Use niche vaults: Polymarket Vault shows 21.93% APY (TVL $1.32M), and the vault list also shows Prediction Markets with 75.58% (TVL line shows 1.32M USDC)—treat this as highly variable.
Expected range: ~20%–75%+ (highest variance; drawdown risk is real).

Audit status

• Audits: 0 (no audit firm names, dates, or report links are presented).
• No bug bounty program details (scope, payout caps, platform) are shown.

What this means in practice

Without published audits, users must treat smart-contract and integration risk as elevated, especially across:

• Pools: AMM math, fee accounting, and potential edge-case exploits.
• Lend: interest rate model correctness, collateral/LTV logic (e.g., Borrow LTV 80 shown for eTHIRD), liquidation engine safety.
• Perps: oracle/mark price mechanics (perps screen shows both Oracle Price $70,582.4 and Mark Price $70,548.4), and funding (example shown Funding Rate -0.0015).
• Vaults: strategy/manager risk and cross-protocol dependencies (vaults are “Powered by Ember Protocol”).

Impermanent loss (IL) estimates (math-based scenarios)

For volatile pairs like SUI/USDC, WBTC, xBTC, BLUE, IL can dominate fee income. Constant-product IL for a single-sided relative move:

• +20% price move (r=1.2): ~0.32% IL
• +50% (r=1.5): ~2.04% IL
• +100% (r=2.0): ~5.72% IL
• +200% (r=3.0): ~13.40% IL These losses occur versus simply holding the assets.

Operational risk flags

• APRs shown in Pools are 24h-annualized, implying yield can be driven by short-term volume spikes.
• Given no published audits, size positions accordingly and prefer markets with deeper liquidity (e.g., SUI/USDC $6.18M TVL, USDC lending $41.51M supply) when possible.

Bluefin integrates Ember Protocol vaults (“Powered by Ember Protocol”), offering automated strategies with clearly posted TVL and APY. The vault dashboard shows meaningful adoption: Total Deposits $68.55M, Total Earnings $2.17M, Depositors 40.69K.

High-signal vault options (with posted APY + TVL)

How to use vaults for earnings

• Vaults are best for users who want exposure to yield strategies (delta-neutral, basis, concentrated liquidity) without manual rebalancing.
• Strategy risk varies materially: “Treasury/MMF” and “delta-neutral stablecoin strategy” are typically less directional than prediction markets or concentrated LP, but all depend on execution and integrations.

Fees and terms

Vault-level fees (performance/management) and lockup terms are not shown in the vault listing provided, so you should treat net APY as what’s currently advertised and verify any additional fee layers before sizing up.

Two differentiated earning mechanisms stand out beyond standard LP fees and money-market lending:

1) On-chain RWA-style yield via “Treasury Vault”

• The R25 Treasury Vault is categorized under Real World Assets and explicitly references Money Market Funds.
• It shows $6.95M TVL and 14.00% APY (denominated in USDC).
• For DeFi users, this is a distinct “CeFi-like yield packaging” approach compared with typical DEX-only fee income.

2) Prediction-market yield via Polymarket integration

• A dedicated Polymarket Vault is listed with $1.32M TVL and 21.93% APY.
• The vault list also shows a Prediction Markets category with 1.32M USDC and an eye-catching 75.58% figure, indicating that prediction-market-derived yield can be substantially higher but likely more variable.

Participation requirements (what’s explicit)

• Both are USDC-denominated vault entries, so participation is straightforward: deposit the required asset (USDC) into the vault.
• Unlike LPing, these mechanisms don’t require managing impermanent loss directly, but they do introduce strategy risk (execution, counterparties/integrations, and market-specific risks for prediction markets).

Bluefin’s earning potential is strongest when you use it as a Sui yield hub: high-fee pools with visible fee generation, high-APR lending markets, and Ember-powered vaults with clear APY/TVL. The tradeoff is security and disclosure: there are 0 published audits and incomplete visibility into protocol-level fee capture.

Top 3 strengths
1) Transparent per-pool economics: fee tiers plus 24h Fees and 24h APR (e.g., SUI/USDC 0.175%, $9,516.79 24h fees, 67.52% 24h APR).
2) Strong passive income menu: lending supply APRs up to 37.36% (WAL) and multiple vaults (e.g., Ember Earn 9.52%, R25 Treasury 14%).
3) Differentiated vault strategies (RWA/MMF and prediction markets) with posted TVL/APY.

Top 3 weaknesses
1) No audits published (0) and no visible bug bounty details.
2) No disclosed LP vs protocol fee split (protocol revenue capture cannot be verified).
3) Many headline pool APRs are 24h-annualized, making them unstable and sensitive to volume spikes.

Recommendation (one sentence): Use Bluefin for diversified Sui-native yield (lending + vaults first, selective LP second), but size risk down until audit transparency improves.
