Rejoice Infinexoooors, sUSD depositors on Infinex will continue to earn rewards into the Synthetix Mainnet launch. This campaign extension ensures low volatility in sUSD as we spin up the Synthetix Liquidity Vault (SLP).
Infinex users who deposit sUSD from September 26th, 2025 until November 7th, 2025 will be eligible to earn rewards and win onchain prizes. For those with sUSD already deposited, congratulations! You'll continue to earn. If you're not yet participating, here's everything you need to know.
How to Participate
From September 26th, 2025, at 00:01 UTC, for six weeks, sUSD depositors and holders on Infinex will earn a pro-rata share of 12,000 OP tokens every week. Rewards accrue continuously and are distributed weekly.
OP Rewards
Yields will vary based on the total value of sUSD deposits, but we’ve put together some convenient estimates for depositors:
- @ 3 million sUSD in total deposits: 13.56% APR
- @ 5 million sUSD in total deposits: 8.14% APR
You can follow current deposits on the Infinex TVL dashboard.
To qualify for an OP distribution, Infinex users must hold a minimum of 1,000 sUSD deposit on the last day of the week.

- 4th winner – 2,000 SNX
