DeFi Strategies with stLINK and wstLINK

Introduction to DeFi with Liquid Staking

Liquid staking tokens unlock a second layer of yield. When you stake LINK through stake.link, you receive stLINK — a rebasing token that grows in value as Chainlink staking rewards accumulate. But stLINK doesn't have to sit idle: it can be deployed across DeFi protocols to earn additional yield on top of the base staking APY.

The stake.link ecosystem currently connects stLINK and its wrapped form (wstLINK) to Curve Finance, Morpho, Uniswap, Beefy, and Folks Finance. Each venue offers a different combination of yield, risk, and complexity. Some strategies are passive single-deposit positions; others involve active leverage loops. The right strategy depends on your risk tolerance, capital size, and how much active management you're willing to do.

This guide walks through four concrete strategies — from the simplest passive earn to leveraged staking — and compares them side by side so you can make an informed allocation decision. Live APY data for all venues is available on the DeFi Integrations section of the analytics dashboard at stakedotlink.money.

Strategy 1: Curve Yield Stacking

The Curve stLINK/LINK pool (factory-stable-ng-403) is the core liquidity venue for stake.link. By providing both stLINK and LINK as liquidity, you earn trading fees from every swap between the two assets, plus SDL incentive rewards distributed via Merkl. The result is a yield stack sitting on top of the underlying staking APY already embedded in stLINK.

Impermanent loss risk is minimal here. stLINK and LINK are near-perfectly correlated: stLINK is a rebasing representation of LINK that only appreciates relative to raw LINK over time, never depreciates. Curve's StableSwap AMM with a high amplification factor (A=500) keeps pricing tight even when the pool becomes moderately imbalanced. This makes the stLINK/LINK pool structurally safer than most DeFi LP positions.

For users who don't want to actively harvest rewards, the optional Beefy integration autocompounds all Curve LP fees and SDL rewards back into more LP tokens. This is the set-and-forget version of the Curve strategy, at the cost of one additional smart contract layer.

Strategy 2: Leveraged Staking via Morpho

Morpho enables wstLINK to be used as collateral to borrow LINK. By looping — depositing, borrowing, restaking, and depositing again — you can multiply your exposure to staking yield. This is the highest-complexity and highest-risk strategy available in the stake.link ecosystem, and should only be attempted by users who understand liquidation mechanics.

The wrapping step is mandatory. stLINK is a rebasing token — its balance updates automatically as rewards accrue — which makes it incompatible with Morpho's accounting model. wstLINK is a non-rebasing wrapper that represents your share of the stLINK pool as a fixed unit, making it safe to use in lending protocols.

In practice, most users who pursue leveraged staking target a 1.5×–2.5× loop rather than the mathematical maximum, leaving a safety buffer against liquidation. Monitor your health factor on Morpho's interface and be prepared to de-lever if LINK price weakens.

Strategy 3: Simple LP with SDL Rewards

A lower-risk variation of the Curve strategy, this approach involves splitting your LINK position in half rather than staking all of it. Half is staked to receive stLINK; the other half remains as raw LINK. Both halves are then deposited together into the Curve stLINK/LINK pool.

By keeping half your position as raw LINK, you forgo the staking yield on that portion — but you also avoid the small risk that stLINK depegs during high market stress. The undeployed LINK also acts as a natural reserve if you want to add liquidity during pool imbalances or absorb short-term volatility without rebalancing.

This strategy is best suited for users who want to participate in the Curve incentive campaign and earn SDL rewards without putting their entire LINK stack through the staking contract. It is the entry-level DeFi strategy in the stake.link ecosystem — simple to enter, simple to exit, and requires no wrapping or leverage management.

Strategy 4: Passive Morpho Vault Lending

The Morpho Vault is the simplest high-yield option in the stake.link DeFi ecosystem. You stake LINK to receive stLINK, wrap it to wstLINK, and deposit once into the Morpho Vault at 0x610f5B68bD1EED68Af649A3fD3DC2CAa1ee4Ae7E. From that point, you earn a triple yield stack with no active management required.

The Morpho Vault lends your wstLINK to borrowers (the same leveraged stakers from Strategy 2), capturing lending interest on top of your underlying staking yield. The 62,500 SDL incentive campaign running through July 2026 adds a third layer. There is no impermanent loss because this is a lending vault, not an AMM — you deposit wstLINK and receive wstLINK back (plus interest) when you withdraw.

The primary risk is smart contract risk — a bug in the Morpho protocol or the vault's lending strategy could result in loss of funds. This risk is inherent to all DeFi protocols. For users who want to earn materially above the base staking APY without taking on leverage or IL, this is the cleanest option.

Risk Comparison

The four strategies occupy different positions on the risk-yield spectrum. The table below summarizes the key dimensions to consider before allocating.

Smart contract risk applies to all four strategies and is non-zero. Morpho, Curve, and Beefy are audited protocols with strong track records, but no smart contract is risk-free. Allocate only what you can afford to have exposed to protocol-level risk, regardless of which strategy you choose.

Choosing the Right Strategy

If you are new to DeFi or deploying a large portion of your LINK holdings, Strategy 4 (Morpho Vault) or Strategy 3 (Simple LP) are the most appropriate starting points. Both require a single deposit decision with no ongoing management and carry the lowest risk profiles in the set. Strategy 4 offers a higher ceiling due to the triple yield stack; Strategy 3 is the simplest entry with no wrapping required.

Strategy 1 (Curve Yield Stacking with Beefy autocompounding) makes sense for users who want to maximize fee and SDL reward capture over a longer time horizon without introducing leverage. The Beefy integration handles reward harvesting automatically, making it nearly as passive as Strategy 4 while maintaining full AMM fee exposure.

Strategy 2 (Leveraged Staking) is exclusively for users who understand how liquidation mechanics work, actively monitor their health factor, and have a plan for de-levering during adverse market conditions. It should not be the first DeFi strategy you attempt with stLINK. Many users find that combining Strategies 1 and 4 — splitting their wstLINK between the Curve pool and the Morpho Vault — gives a diversified yield profile without needing to manage leverage at all.
