Top 5 Emerging DeFi Yield Opportunities on Base / Arbitrum / Polygon (Under-the-Radar)

By Alex Assoune Dec 03, 2025

As DeFi continues to expand across multiple EVM-compatible chains, new yield opportunities pop up regularly. While many investors chase blue-chip vaults and big-name protocols, there are “hidden gems” – emerging yield farms and vaults on chains like Base, Arbitrum and Polygon. Some offer impressive yields — but they come with extra risk. If you approach them with care, they can be rewarding.

Here are five promising, under-the-radar DeFi yield opportunities that are currently gaining traction — along with what you should check before diving in.

1. Yield Derivatives & Tokenized-Yield Protocols on Arbitrum — Pendle Finance

🔎 What makes Pendle interesting

Pendle lets users split yield-bearing assets into two parts: a “Principal Token (PT)” and a “Yield Token (YT).” The PT represents the underlying asset (e.g., a staked or liquidity token), while YT represents the future yield. This structure allows you to lock in yield (via PT) or speculate on future yield (via YT). (Medium)
On Arbitrum, Pendle has grown into a meaningful size — there’s steady volume and a non-trivial TVL, which suggests it’s attracting interest. (NFT Evening)

✅ What you get

Ability to lock in yield now (via PT) — useful in volatile markets.
Flexibility — you can trade yield exposure, effectively “selling future returns.”
Potentially higher yields than simple staking, if yield tokens (YT) appreciate.

⚠️ What to watch out for

Yield tokenization adds complexity — risk and reward are separated, but also more variable.
Liquidity for YT/PT markets may be thin → slippage or difficulty exiting.
Smart-contract and protocol risk are elevated on “newer” DeFi primitives like yield splitting.

Bottom line: Pendle is a creative, under-the-radar way to get exposure to yield derivatives. Worth exploring if you understand the mechanics.

2. Multi-Chain Auto-Compounded Vaults via Aggregators — Beefy Finance & Cross-Chain Vaults

🔎 What’s new

Beefy remains one of the most active multi-chain yield aggregators — and it continues to expand vault support across chains including Polygon, Arbitrum, and others. (BlockWave Trends)
These vaults auto-compound yields, reinvest profits, and often cross-chain route assets to chase higher yields. That makes them a potential “set and forget” option for users wanting exposure across less mainstream chains. (CoinBrain)

✅ Benefits

Auto-compounding saves time and maximizes returns without manual staking/re-staking.
Diversifies risk across chains and pools — less exposure to a single chain’s gas, liquidity, or demand issues.
Lower maintenance — ideal for investors who prefer passive yield.

⚠️ What to check

Smart-contract risk increases with added complexity (aggregator + underlying vault + cross-chain bridges).
Yields may look good on paper — but high APYs (especially on smaller chains/pools) often come with low liquidity or high volatility.
Always check that vaults are audited and that the underlying pools have enough liquidity to handle withdrawals.

Bottom line: Multi-chain vaults via Beefy (and similar aggregators) give a balanced mix of yield and convenience — a top candidate if you want hands-off exposure.

3. Stablecoin & Lending Vaults on Major Chains — e.g., via Aave v4 on Arbitrum or Polygon

🔎 Why it matters now

On some chains, stablecoin lending remains one of the lowest-volatility yield strategies. In 2025, stable-rate lending on Aave v4 and similar platforms is still among the most reliable ways to earn yield. (Cryptomny)
As yield from volatile LPs becomes riskier, stablecoin vaults are an attractive option for those who value capital preservation over max yields.

✅ Benefits

Lower risk compared to LP or token-reward farms — no impermanent loss, minimal exposure to token price swings.
More predictable returns — useful for “crypto savings” or stable allocations in a diversified portfolio.
Easier to understand for beginners or risk-averse investors.

⚠️ What to check

Yield rates are generally lower compared to LP farms — expect modest but steady returns.
Even stablecoin protocols carry smart-contract and protocol risks, so check audits and liquidity backing.
Inflation / depeg risk for stablecoins — especially for lesser-known ones; stick to stablecoins with high trust and large liquidity.

Bottom line: For a conservative, stable yield — especially for funds you want to hold long-term — stablecoin and lending vaults remain among the safest bets on these chains.

4. Niche LP / Liquidity Pools on Polygon — lesser-known DEX LPs & AMMs

🔎 What’s under-the-radar on Polygon

Outside of the major LPs, there are smaller farms and DEXs on Polygon offering unusually high yields — often due to token-rewards or incentive programs rather than underlying trading volume. For example, certain pools have offered large token-reward bonuses on top of base liquidity returns. (rivo.xyz)
Because Polygon transactions are relatively cheap, LP farming here can be more accessible and cost-efficient than on higher-fee chains.

✅ Potential upside

High yield potential — especially if token-rewards + trading fees line up well.
Lower barrier to entry due to low gas costs — good for small to mid-sized investors.
Opportunity to find undervalued or overlooked pools before they become overcrowded.

⚠️ Risks

High risk of impermanent loss if token prices diverge. (changelly.com)
Pools with high yield often have low liquidity or volatile tokens — can be risky or hard to exit.
Smart-contract risk and “rug-pull” risk tends to be higher for niche/low-cap projects.

Bottom line: Polygon offers some of the most accessible and potentially high-reward LP opportunities — but these come with increased risk. Good for yield hunters who understand volatility.

5. “Hybrid” Yield-Derivative or Vault Strategies — combining staking / lending / yield derivatives on multiple chains

🔎 What this means

Instead of depending on a single strategy, some newer projects allow hybrid strategies: stable lending + reward tokens, or LP + yield derivatives + auto-compounding. These mix lower-risk and higher-reward elements to balance yield and safety.

Protocols that offer yield-tokenization, staking, and vaults — sometimes across chains — give access to a diversified yield stack rather than putting all eggs in one basket.

✅ Advantages

Spread risk: if a token or LP fails, stablecoin or lending portions can act as a buffer.
Flexibility: mix-and-match strategies depending on market conditions.
Potentially smoother returns — less exposure to single-asset volatility.

⚠️ What to watch

Complexity: harder to monitor, higher due diligence required.
Smart contract exposure increases with each added layer.
Withdrawal / exit risk — if one piece of the composite strategy fails, it might affect the rest.

Bottom line: Hybrid yield-derivative strategies can be a strategic way to balance yield and risk — ideal for more experienced DeFi users who want diversified exposure.

🧭 How to Choose (and Monitor) Under-the-Radar DeFi Opportunities

🔹 Do your security homework

Check smart-contract audits, TVL, token distribution, and liquidity. Avoid protocols with anonymous teams, no audit, or very low liquidity. (BlockWave Trends)

🔹 Use small amounts first

Treat under-the-radar pools as experiments. Use small capital to test how the pool behaves, and how easy it is to enter/exit.

🔹 Diversify across chains and strategies

Don’t put everything in one chain or one strategy — split between stable vaults, LPs, and hybrids.

🔹 Monitor yield sources and sustainability

Yields that look too good to be true may rely heavily on token-rewards rather than genuine trading volume or lending demand — those are often unsustainable.

🔹 Be ready for volatility, especially in LPs or reward-token farms

Impermanent loss, token price crashes, or liquidity dryness can hit — always consider risk vs reward.

✅ Final Thoughts: Under-the-Radar ≠ Easy — but Sometimes Worth It

Emerging DeFi opportunities on Base, Arbitrum, and Polygon offer a chance to earn yields that outperform mainstream vaults — but with higher complexity and risk.

If you approach with caution — do your research, diversify, start small, and stay informed — you might uncover yield strategies that deliver outsized returns.

Just remember: high yield almost always equals higher risk.
