S yield FAQ
The highest S rate we currently track is 10.42% APY on OKX Earn, which we grade B for safety. These are base rates refreshed daily — not promotional teasers.
It depends on the platform, not the coin. We grade every platform A–F on five checks: regulation, proof-of-reserves, flexible withdrawals, an insurance fund, and track record. Check the grade next to each rate before depositing — a higher APY often means higher risk.
No. We track 8 platforms for S and publish base rates only — never the headline promo or teaser tiers that apply to tiny balances. Floating rates are labelled as snapshots, so the number reflects what a normal balance realistically earns.
