Solana Circuit 1: Pye Finance and the next layer of staking markets on Solana

In the first Solana Circuit community space, the Raiku team hosted Eric from Pye Finance for a technical discussion about validator economics and the missing market structure around staking. The session laid out a clear thesis: Solana’s staking system already produces a rich set of cash flows, but the tooling to price, trade, and finance those cash flows is still mostly off-chain. Pye Finance aims to move that activity on-chain by extending stake accounts, introducing term staking, and tokenizing future rewards.

Background: term staking exists off-chain today

A recurring theme was that sophisticated stakers already negotiate custom validator deals. Large delegators often commit stake for fixed periods in exchange for better economics, such as:

• reduced commission for longer lockups
• explicit priority fee or MEV sharing
• bespoke reward schedules

These arrangements are currently handled via private agreements and manual accounting. From a protocol perspective, Solana stake accounts do not natively encode these terms. The result is friction for both sides: validators cannot easily offer differentiated products, and stakers cannot exit or refinance positions without breaking the relationship.

Why Solana’s PoS design makes this tractable

Eric’s move from Ethereum to Solana was framed as an engineering and market design decision, not a narrative one. He argued that Solana’s validator revenue mix creates a more legible basis for financial products:

• inflationary staking rewards
• priority fees tied to transaction inclusion
• MEV that is increasingly explicit and shareable through validator policy

Because these cash flows are already measurable at the validator layer, Solana is a natural substrate for turning staking into something closer to a fixed-income market.

Pye’s base primitive: an upgraded stake account

Pye Finance starts with a stake-account extension implemented as a CLI-driven upgrade to standard Solana stake accounts. The upgrade allows validators to create term-locked staking positions with programmable economics.

Conceptually, this adds three capabilities:

1. Fixed-term lockups
   Delegators can choose a maturity date. Stake remains delegated through that term, improving validator predictability.
2. Term-dependent reward splits
   Commission and fee sharing can vary by lock length or deal class. This enables validators to price commitment.
3. On-chain representation of the contract
   The stake position becomes an object that can be tokenized and traded without changing the validator’s locked stake base.

Pye emphasized this upgrade as a free public good, intended to become a standard building block rather than a gated product.

Tokenization model: splitting principal and yield

Once a term position is created, Pye tokenizes it into two SPL tokens:

• PT, the principal token
  Represents the right to redeem the original SOL at maturity. It is yield-less. At expiry, PT redeems 1:1 into SOL.
• RT, the reward token
  Represents the staking rewards generated during the term. Holding RT gives exposure to the yield stream; selling RT transfers that exposure.

This mirrors classic fixed-income decomposition where a claim on principal and a claim on coupons are separated. The split enables multiple strategies:

• A staker can sell RT upfront to realize yield immediately while keeping PT
• A staker can hold both PT and RT for normal staking behavior
• Secondary traders can price and acquire Solana yield without running validators

A key claim is that this structure makes future staking rewards a first-class on-chain asset, rather than an implicit side effect of delegation.

Liquidity and pricing: a universal order book for PT

One listener brought up a previous Solana attempt at yield tokenization (Jungle) that struggled with fragmented liquidity. The critique was that splitting stake by validator and term can lead to thin markets and poor price discovery.

Pye's response was to unify liquidity around PT. Since PT across validators is redeemable into SOL at maturity, PT instruments share a common payoff function. Pye proposes a universal order book where PT from different validators can clear in the same market, with pricing largely driven by time to maturity and implied yield.

RT is naturally more idiosyncratic, since yield depends on validator performance and fee policy. The team suggested that improved PT liquidity materially helps RT pricing, because RT becomes the residual between locked SOL value and principal value over time.

System effects: stake stays locked while users get exits

A subtle but important point is that Pye decouples user liquidity from validator lockups. In standard delegation, the only way to exit is to deactivate stake, which directly reduces a validator’s stake base. With PT and RT tradable, a delegator can exit by selling their position, while the stake remains locked and delegated until maturity.

Eric argued this could reduce sudden stake churn during market stress, because liquidity is provided by secondary markets instead of mass unstaking. In fixed-income terms, Solana staking becomes adjacent to a tradable yield market rather than a single monolithic spot position.

What Pye is not doing yet

Pye repeatedly stressed focus. The team is not trying to expand into generalized lending or multi-asset yield products in the near term. The roadmap is validator-centric:

• ship the stake-account upgrade broadly
• onboard more validators into term products
• scale PT liquidity and standardized RT markets
• harden pricing and risk logic around variable validator yield

The idea is to make Solana staking legible as a market first, then build outward if it becomes a stable base layer.

Takeaway

The core technical contribution of Pye Finance is not a new yield product, but a new representation of staking itself. By adding term lockups to stake accounts, splitting principal and yield into SPL tokens, and targeting unified PT liquidity, Pye is building the primitives for a real yield curve at the validator level.

If this works, Solana staking shifts from passive delegation to a composable financial market where validators can price commitment and stakers can trade future rewards without destabilizing validator security.
