Orca and Loopscale, two established Solana DeFi protocols, are merging into a new entity called Formation, according to The Block. The combined company aims to move beyond on-chain trading infrastructure and into financing for artificial intelligence, energy, robotics and defense — sectors that traditionally raise capital in institutional settings rather than on blockchains.

The merger pairs a major automated market maker with a young but structurally distinctive lending protocol. Orca operates one of the better-known trading venues in the Solana ecosystem. Loopscale, which went live publicly in 2025, provides the lending half of the arrangement.

What does Loopscale bring to the merged entity?

Loopscale's lending model differs from most of DeFi in two ways. First, it offers fixed-rate borrowing and lending against digital assets, while variable rates remain the industry norm. Second, it matches borrowers and lenders through an order book rather than a pooled structure.

In a typical pool-based market such as the dominant lending protocols, depositors place funds into a shared pool and an algorithm sets rates based on utilization. Loopscale instead lets lenders post the terms they want and borrowers post what they will accept, with the protocol pairing matching offers. That architecture gives lenders price certainty and gives borrowers predictable costs — a prerequisite, structurally, for underwriting anything that resembles real-world credit.

The two protocols already had operational overlap. In March 2025, Loopscale announced an integration accepting LP tokens from Orca and Raydium — the receipts liquidity providers receive when depositing into automated market maker pools. The integration was framed at the time as unlocking access to more than $1 billion in liquidity through Loopscale's order-book lending, letting liquidity providers borrow against idle positions.

What are the operational consequences for users?

For existing users of both protocols, the practical questions outweigh the rebranding. How Formation handles current products, collateral types and governance will determine whether the merger disrupts active positions or preserves them. Neither protocol's user base signed up for real-world credit exposure, so any migration of treasury or collateral policy will require clear communication.

The strategic pivot also introduces risk profiles that pure crypto lending does not carry. Lending to real-world companies means credit risk of a different kind: a liquidation engine can sell crypto collateral in seconds, whereas recovering funds from a struggling hardware startup takes considerably longer. Financing defense and energy projects adds regulatory exposure that on-chain lending markets have never faced, including questions about who is permitted to lend into such deals and under which jurisdictions.

Key open items include the financial terms of the merger, the leadership structure of Formation, the first financing deals the entity announces, and its process for vetting borrowers. Those disclosures will signal whether Formation intends to operate as a credit underwriter with on-chain rails or as something closer to a syndication platform.

The deal marks one of the more explicit attempts by Solana-native infrastructure to reposition itself as a financing layer for physical-economy sectors. Whether institutional capital follows depends on Formation's first announced deals and the restrictions it places on participation in defense-related lending.
