SINGAPORE, June 5, 2025 -- Amber International Holding Limited (Nasdaq: AMBR) ("Amber International" or the "Company"), a leading provider of institutional crypto financial services & solutions and operating under the brand name "Amber Premium", and DeFi Development Corp. (Nasdaq: DFDV), the first US public company with a treasury strategy built to accumulate and compound Solana ("SOL"), today announced the signing of a non-binding memorandum of understanding (MOU) on a strategic collaboration across Solana-based treasury acquisition, staking, and yield product development.

The MOU demonstrates both parties' visions on SOL-based product development and validator infrastructure usage, while expanding institutional client access to Solana-linked investment opportunities. Amber Premium could serve as a broker and execution partner for DFDV's treasury strategy and facilitate the structuring and distribution of yield-bearing SOL-denominated products across its client network.
