Quartz

Quartz, later rebranded as Pyra, was a DeFi-native neobank on Solana that allowed users to earn yield on deposited crypto assets through Drift Protocol lending pools and spend that yield through a physical Visa debit card. The project shut down permanently on June 15, 2026, following the April 2026 Drift Protocol exploit, which resulted in approximately $286 million in losses and rendered the yield infrastructure that Quartz/Pyra depended upon inoperable.

What It Was

Quartz and Pyra (the post-rebrand name) addressed a practical question that DeFi yield users face: how to access yield earnings for everyday spending without selling the underlying asset. The product's model was:

1. Deposit: User deposits crypto assets (SOL, stablecoins, or other supported tokens) into Quartz/Pyra.
2. Yield generation: Deposited assets are deployed into Drift Protocol's lending pools, earning variable APY from protocol borrowers.
3. Spend: User receives a Drift Protocol-issued Visa debit card. When they make a purchase, Quartz/Pyra draws down from the lending position to cover the payment.
4. Loans: Users could also take over-collateralized loans against their deposited assets, using the card as a spending interface for borrowed funds while their deposits continued earning yield.

This model is sometimes called a "DeFi card" or "crypto neobank": the user's savings are always deployed in a yield-generating position, and spending draws from yield or borrowed funds rather than requiring the user to sell their holdings.

CEO and Team

The company was led by CEO Diego Garcia. No further public information about the company's corporate structure, investor base, or additional team members has been disclosed in available sources.

Relationship to Drift Protocol

Quartz/Pyra's architecture was built on top of Drift Protocol, Solana's perpetuals DEX and lending platform. This tight dependency was both an integration strength — Drift's deep liquidity and yield rates powered the product — and an existential risk factor.

Drift Protocol Exploit and Shutdown

On April 1, 2026, Drift Protocol suffered an exploit that resulted in losses of approximately $286 million. The exploit was subsequently attributed to the DPRK-linked Lazarus Group by blockchain security researchers. The loss left Drift Protocol insolvent and unable to honor full withdrawals, which directly impaired Quartz/Pyra's ability to process redemptions and maintain its business model.

Quartz/Pyra formally ceased operations on June 15, 2026. The team opened a withdrawal portal for remaining user funds and set a withdrawal deadline of September 15, 2026 — a 90-day window during which users could attempt to recover any accessible remaining balances.

Historical Context

Quartz launched during a period of growth in the "crypto neobank" product category, where several projects across different chains attempted to build consumer-facing spending interfaces backed by DeFi yield. On Solana specifically, the combination of high-yield lending markets and low transaction costs made this product model more viable than on high-gas chains. The Drift Protocol exploit represented one of the largest single DeFi security incidents on Solana and demonstrated the systemic risk that tightly coupled DeFi products face when a single underlying protocol fails.

As of the time of writing, the Quartz/Pyra product is no longer accepting deposits, issuing new cards, or processing new transactions. Only the withdrawal portal remains active until the September 2026 deadline.
