How SPK earns on OKX Earn
When you deposit SPK into OKX Earn's earn product you receive 16 % APY as a Flexible rate. The platform puts the asset to work and shares the yield — your balance grows without you doing anything.
This is a base rate, not a promotional teaser: it's what an ordinary deposit actually earns. OKX Earn carries a YieldScope safety grade of B, so weigh the yield against platform risk — a higher rate on a weaker grade is not automatically a better deal.
Rates on SPK move with lending demand and market conditions. We re-check them daily and keep a history, so you can see whether today's number is unusually high, unusually low, or steady.
