Stablecoin Flows on Aptos — A Liquidity Story in the Making
From just $20M in October 2024 to nearly $1.3B today— Aptos stablecoin supply has evolved into a leading on-chain liquidity signal.
But it’s not just the numbers — it’s how the supply has grown that matters.
Here’s the breakdown from a data analyst’s lens 
USDT | The Core Driver
Since launch, the USDT curve on Aptos has been consistently vertical.
In the past 30 days alone, >$105M was added to its supply — now hovering around $955M, after briefly pushing past $1B.
This isn’t passive growth — it’s sustained demand, likely tied to active trading + farming loops.
If the trend stabilizes, we’re looking at a $1B+ floor soon.
USDC | The Breakout Curve
Started at just $9.8M in Dec ‘24 — now sits above $300M.
Key inflection point: March 2025, when supply jumped from $86M → $243M.
A $157M increase in a single month?
That’s not retail behavior — that’s deep DeFi capital rotating in.
USDC is quickly becoming a second anchor.
BUILD | The Third Pillar
Now at ~$42.8M. Peaked in March at $53.2M.
Less aggressive, but still stable. BUILD adds diversity to Aptos’ stablecoin liquidity stack — likely used across specific verticals (e.g. ecosystem-native protocols).
What we’re witnessing isn’t just inflow — it’s structured capital allocation.
Stablecoins are sticky liquidity, and Aptos is becoming a natural settlement layer for them.
The shift is clear: Aptos is quietly positioning itself as a stablecoin-native chain — and the data backs it up.
