Solana's stablecoin ecosystem has been experiencing explosive growth. The total supply surged from approximately $3 billion just two years back, climbed to roughly $12 billion last year, and now hovers around $16 billion heading into December. The trajectory at this point feels less like organic fluctuation and more like a structured expansion—the kind of growth pattern you'd expect when an entire ecosystem is being methodically built out. What's driving this momentum? Worth keeping tabs on.
