PT-BulkSOL on Loopscale: 40% APY and AURA Points at the Same Time

Most people farming BULK AURA are depositing USDC and waiting. A smaller group is running the loop — PT-BulkSOL on Loopscale, earning up to 40% APY while their BulkSOL exposure stacks weekly AURA. Here’s how it works.

The Yield Stack

Before getting into mechanics: understand what you’re actually earning when running this strategy.

Layer 1 — BulkSOL base yield: ~7% APY from Solana staking rewards via the BULK validator set.

Layer 2 — MEV tips: BulkSOL captures MEV from the BULK validator set and distributes it to holders.

Layer 3 — Exponent fixed APY: PT-BulkSOL-20JUN26 locks in 7.83% fixed APY on your BulkSOL exposure, regardless of what the underlying yield does before June 20 maturity.

Layer 4 — Loopscale loop APY: Borrowing SOL against PT-BulkSOL collateral and cycling back into BulkSOL amplifies your effective exposure. Up to 40.2% APY at max leverage.

Layer 5 — BULK AURA points: BulkSOL exposure earns weekly AURA in Season 1. Exponent explicitly displays BULK point accrual on BulkSOL deposits.

Post-mainnet, BulkSOL holders also receive 12.5% of all BULK Exchange trading fees. That stream isn’t live yet but activates at mainnet launch.

Running this strategy while simultaneously pre-depositing USDC means AURA is coming from two separate pools: the depositor allocation and the BulkSOL holder allocation.

What PT-BulkSOL Is

Exponent Finance is a yield-stripping protocol — it separates the yield from the principal of a yielding asset.

When you deposit BulkSOL into Exponent, you receive two tokens:

• PT (Principal Token): Redeems for 1 BulkSOL at maturity. Fixed return, no variable exposure.
• YT (Yield Token): Receives the yield on your underlying BulkSOL during the term. Time-decaying — worth less as maturity approaches.

PT-BulkSOL-20JUN26 matures on June 20, 2026. Depositing BulkSOL now gives you a fixed 7.83% APY locked until then. After maturity, you redeem PT for BulkSOL at 1:1.

The PT is what makes the loop work: it’s a fixed-value asset that Loopscale accepts as collateral.

The Loop Step-by-Step

Read this section completely before starting. The loop is a leveraged position. Liquidation is possible.

1. Swap SOL → BulkSOL on Titan Exchange
2. Deposit BulkSOL into Exponent Finance → receive PT-BulkSOL-20JUN26
3. Deposit PT-BulkSOL on Loopscale as collateral
4. Borrow SOL against your PT-BulkSOL collateral
5. Swap borrowed SOL → BulkSOL on Titan
6. Repeat steps 2–5 until target leverage is reached
7. Monitor your LTV ratio — Loopscale uses fixed-rate borrowing (no rate surprise), but price depeg between BulkSOL and SOL will move your LTV

The loop amplifies your effective BulkSOL exposure by 2–5x depending on leverage. More loops = more yield + more AURA, but also more liquidation risk.

Risk Profile

Loop positions are leveraged. If BulkSOL depegs relative to SOL, your collateral value drops and you risk liquidation. Only run this if you understand leveraged DeFi. Start with 1-2x loop, not max leverage.

Liquidation risk: BulkSOL tracks SOL price but is not guaranteed to stay pegged 1:1. A depeg event — caused by validator issues, panic selling, or technical problems — reduces your collateral value and can trigger liquidation.

Smart contract risk: You’re exposed to three protocols simultaneously (Titan, Exponent, Loopscale). A bug in any of them affects your position. Loopscale is audited; Exponent is double-audited.

Maturity risk: PT-BulkSOL-20JUN26 matures June 20. If you’re running the loop past maturity, you’ll need to roll positions. Plan this in advance.

Rate lock is protective: Loopscale’s fixed-rate borrowing means your borrow rate is locked at entry. You’re not exposed to variable rate spikes — which was a major risk factor in older leveraged yield strategies.

Who This Is For

This strategy makes sense if:

• You have $5K+ to deploy (the complexity overhead isn’t worth it below this)
• You’ve used leveraged DeFi before and understand LTV management
• You’re comfortable monitoring the position and unwinding if BulkSOL shows stress
• You want to maximize AURA while also earning meaningful real yield, not just farm points

This strategy does not make sense if:

• You’ve never used a lending protocol before
• You’re using capital you can’t afford to lose to liquidation
• You need liquidity before June 20 and don’t want to manage an unwind

How This Stacks with Pre-Deposit USDC

Running the loop does not replace pre-depositing USDC — it stacks on top of it.

The AURA allocation for depositors and the AURA allocation for BulkSOL holders come from different pools. A wallet running the loop and simultaneously holding a USDC pre-deposit is earning from two separate AURA sources.

The capital allocation that makes sense: keep enough USDC in pre-deposit to hold a meaningful depositor position (USDC × time is its own AURA vector), and deploy remaining capital into the BulkSOL loop for amplified AURA from the BulkSOL pool plus the yield.

See the Season 1 hub guide for full capital tier recommendations across all vectors.

Also see the dilution calculator — the loop strategy’s higher AURA earnings matter more in early weeks when total AURA is smaller and each point is a larger percentage of the pool.

The Bottom Line

The loop is not for everyone. It requires active management, carries real liquidation risk, and involves three protocols simultaneously.

For wallets with $5K+ and DeFi experience, it’s the highest-leverage AURA farming play available right now — while also generating meaningful real yield through Loopscale’s fixed-rate borrowing.

If you’re not ready for the loop, start with pre-depositing USDC. That’s the no-risk floor. You can always add BulkSOL exposure later.
