Jupiter brings nOPAL credit strategies to Solana vault beta

Jupiter named four curators for its Solana Vaults beta on Friday, expanding on an earlier launch lineup of six vaults from three curators.

The announcement named Bitwise, Re7 Labs, K3 Capital and Hivemind. K3 Capital did not appear in the earlier lineup. The announcement therefore carried a wider curator roster than Solana Compass’s earlier three-curator lineup.

Solana Compass listed the launch lineup as six vaults from three curators:

• Hivemind: Offerbook Liquidity Vault.
• Bitwise: JupLend Optimizer, sUSDai Yield and sUSDai Multiply.
• Re7 Labs: nOPAL Lending and nOPAL Looping.

Re7 Labs built the two vaults on nOPAL. Plume Network’s page for BlackOpal LiquidStone II, the vault behind those tokens, lists about 11% APY and roughly $112 million in deposits.

The asset beneath nOPAL

nOPAL represents a tokenized stake in the BlackOpal LiquidStone II vault. That vault bundles short-duration Brazilian credit card receivables into a yield-bearing instrument. In plain terms, these are card payments that merchants are still waiting to be paid.

For an investor, the entry point is a deposit into the vault. The investor receives nOPAL tokens as receipts and earns yield from the spread between the discounted purchase price of the receivables and their full face value when they settle.

Each transaction starts with an investor deposit. The vault then acquires Brazilian card receivables below their face value. When the card payments settle, the gap between the purchase price and collected value creates the return. Investors fund merchant receivables, and that discount supplies the yield.

Yield, scale and risk

Crypto Briefing reported a historical range of 8% to 12% APY in September. Returns are not fixed, and past performance does not guarantee future results.

Credit card receivables still carry risk. Default risk, Brazilian macroeconomic conditions, interest rate policy and consumer spending patterns all affect the quality of the underlying assets. The listed yield sits alongside those risks rather than replacing them.

The rate’s movement matters. A September range of 8% to 12% shows that the vault has not offered one fixed yield, and Plume’s 11% listing sits within that band. For depositors, the practical issue is a variable return attached to receivables, not a guaranteed annual coupon.

A route already tested on Solana

Kamino Finance launched a dedicated nOPAL market in September. Re7 Labs has also served as an official Kamino vault curator since September 2024. The Jupiter rollout adds another route to an asset that already had a Solana venue.

The timing gives Jupiter an existing operating relationship to build on. It adds a distribution layer to a strategy that already had a Kamino market and a Plume vault, rather than creating a new receivables pool.

What does this change for Solana users?

The launch fits Jupiter’s push beyond swaps. It also brings Plume’s real-world asset vaults to a wider pool of Solana users through a single interface. Decrypt framed the broader release as including baskets, yield vaults and a new portfolio; Solana Compass reported Baskets, curated Vaults and Portfolio V3.

For users, the practical change is distribution rather than a new yield mechanism. Plume’s products become reachable through Jupiter, while nOPAL continues to rely on the same receivables structure and variable returns. K3 expands the curator roster, though the earlier six-vault lineup included no K3 product.

The market-structure change is clear: nOPAL now has a Jupiter distribution layer alongside its dedicated Kamino market and Plume vault. The next test is whether that broader interface can add deposits and sustain usage while investors continue to assess defaults, Brazilian conditions and variable returns.
