Exponent raises $5M seed to expand onchain yield on Solana

Exponent Finance raised $5 million in a seed round led by Multicoin Capital to expand its Solana-based yield exchange into broader onchain yield infrastructure. Other investors in the round included Solana Ventures, RockawayX, L1D, Prelude and Theia Blockchain, along with angel backers Anatoly Yakovenko and Nick Ducoff. Fundraising began in May 2025 and the round closed in August 2025. The capital was raised in a single tranche and structured as a simple agreement for future equity with token warrants. Exponent declined to disclose valuation or whether investors took board or observer seats. The new seed brings total capital raised to $7.1 million after a $2.1 million round in November 2024.

The company plans to roll out an updated platform in May 2026 that converts its existing yield exchange into infrastructure for active rate management on Solana. The release will add a fully onchain interest-rate order book and strategy vaults. The order book will let users swap variable yield exposure-such as staking or lending returns-into fixed-rate or leveraged positions and set fixed-term, fixed-rate positions for variable returns from lending protocols.

Strategy vaults are designed for users who prefer passive exposure. Asset managers will be able to package interest-rate strategies, including fixed-rate looping and hedging, and offer them as onchain products. Vaults will operate under predefined policies that restrict how managers can deploy capital. Early partners for the vaults include RockawayX, Hastra (which manages Figure’s HELOCs), OnRe and Solstice. Exponent is preparing markets for stablecoins, real-world assets and Solana-denominated products.

Since its launch in late 2024, Exponent has processed more than $2 billion in yield volume across over 35,000 users. The platform generates revenue from fees charged when issuing derivative positions tied to yield assets and from trading fees. The startup has a 12-person team and is prioritizing the platform launch and security work in the near term. About $1 million of the new funding is earmarked for security, including audits and a bug bounty program, with some costs possibly covered by the company treasury.

Exponent plans to remain focused on Solana, citing the network’s transaction performance and user experience as alignment with the company’s goal to scale onchain financial markets.
