RateX

RateX is a Solana-native protocol that treats yield as a tradable asset class. Built by Rate Labs Ltd and launched on Solana mainnet on October 17, 2024, it separates the yield component of yield-bearing assets from their principal, then offers traders and liquidity providers distinct instruments to speculate on, hedge, or lock in those yields. The protocol has since expanded beyond its original yield-trading core into a broader structured finance layer with its Mooncake product, which introduces a liquidation-free leveraged token market.

Yield Tokenization at the Core

RateX works by ingesting yield-bearing assets — such as JitoSOL, mSOL, sUSD, dfdvSOL, and others — and converting them into a standardized form using a rebasing mechanism. Where most liquid staking tokens appreciate in value to reflect accrued yield, RateX represents that same accumulation by increasing the quantity of Standard Tokens (ST) held by the protocol. This normalization step makes diverse yield sources comparable and composable within a single AMM.

From any deposited yield-bearing asset, RateX mints two distinct instruments:

Yield Tokens (YT) represent the right to receive the yield generated by the underlying asset from now until a specific expiration date. Their price reflects the market's implied APY for that asset over the remaining period. As expiration approaches, YT values decay toward zero because yield has already been collected. Traders who believe a protocol's APY will rise can buy YT to gain long exposure; those who expect yields to compress can short them by borrowing YT and selling into the pool.

Principal Tokens (PT) represent the underlying capital and trade at a discount to par. At maturity, each PT redeems 1:1 for an ST. A user who buys PT at a discount effectively locks in a fixed return — the spread between purchase price and par value — regardless of what the floating APY does for the remainder of the contract term. This makes PT a fixed-income instrument within an otherwise variable-rate DeFi environment.

Three Ways to Participate

Leveraged yield trading is the protocol's flagship feature. Traders post margin and borrow from the protocol to take leveraged long or short positions in YT, with maximum exposure of up to 10x. A trader who expects mSOL staking rewards to climb can post 1 SOL as margin, have the protocol mint and lend 10 ST, swap those into 100 YT, and hold a position ten times the size of their initial collateral. Profits and losses are settled against movements in the implied APY.

Earn converts floating-rate yield into fixed income. A holder of a yield-bearing asset deposits it, receives YT and PT, then sells the YT into the pool at the prevailing implied rate. The user keeps the PT — which matures at par — and receives proceeds from the YT sale upfront, effectively locking in a guaranteed return for the duration of the contract.

Liquidity provision lets participants deposit yield-bearing assets as collateral to mint YT/ST pairs for the AMM. LPs earn yield from their deposited collateral, a share of trading fees, and PnL from acting as counterparties to traders. The AMM uses a time-decaying impermanent loss mechanism that causes LP exposure to naturally wind down as contracts approach expiration, reducing the open-ended risk typical of constant-product AMMs.

Mooncake: Liquidation-Free Leverage

In November 2025, RateX launched Mooncake, its second product line and the use case for its $7 million strategic funding round. Mooncake is a permissionless leveraged token market that extends the protocol's reach beyond yield-rate speculation. It offers tokenized funding positions and USD-denominated yield instruments, with a structural design that eliminates forced liquidation. Users can take leveraged exposure to yield and funding rates without the risk of margin calls that characterize perpetual futures platforms.

Funding and Backing

RateX has raised $10.4 million across three rounds. Its seed round drew backing from GSR, SNZ Holdings, Presto Labs, Animoca Ventures, Initial Ventures, G Ventures, KuCoin Ventures, Summer Ventures, and LeadBlock Bitpanda Ventures. The $7 million strategic round completed in November 2025 brought in Animoca Ventures, ECHO, GSR, Crypto.com Capital, Gate, Rzong Capital, BGX Capital, and Summer Capital. The protocol also received a grant from the Solana Foundation and took first prize at the 2024 Solana Renaissance MCM hackathon competition.

Integrations and Partners

RateX has built integrations with several major Solana protocols. Jupiter provides liquidity routing and governance support. Jito's liquid staking token (JitoSOL) was among the first yield-bearing assets supported on the platform. Solayer's sUSD is available for yield trading. DeFi Development Corp. integrated its dfdvSOL liquid staking token in June 2025, making it accessible to margin-based yield strategies. In mid-2026 the team was engaging with Perena and Huma Finance around on-chain credit yield opportunities, reflecting continued expansion of supported asset types.

Token and Status

RateX published $RTX tokenomics in December 2025. The protocol remains active: as of late July 2026, the team was notifying users of expiring and rolling market contracts (sUSDu-2607 expired; sUSDu-2610 opened), a routine that reflects an operational, live trading environment with real users managing positions across contract cycles.
