Guide to SPA token staking, veSPA governance, and xSPA rewards in the Sperax ecosystem. Covers lock mechanics, voting power, reward claiming, and governance participation. Use when explaining SPA tokenomics, helping users stake, or answering governance questions.
The Sperax governance system uses a vote-escrowed model: lock SPA to get veSPA, which gives governance voting power and protocol fee rewards.

| Value accrual | 30% of USDs yield + 100% of protocol fees → buyback-and-burn |

Lock your SPA for 7 days to 4 years to receive veSPA:
veSPA = SPA × (lockup_days / 365)
Example: Lock 1,000 SPA for 2 years → receive 2,000 veSPA (decaying over time)
xSPA is the reward distributed to veSPA stakers weekly (Thursdays UTC).
| Option | What happens | |--------|-------------| | Stake xSPA → veSPA | 1:1 ratio, but requires ≥180-day lock | | Redeem xSPA → SPA | 0.5–1.0 SPA over 15–180 days |
Redemption formula:
Receivable SPA = (xSPA × (redeemDuration + 150)) / 330
