Sui’s stablecoin supply reached $537.74 million on November 13, 2026, up 10.33% over the past 30 days.
The timing is notable. During the same period, total US dollar stablecoin supply across all networks fell 5.34%, as Sui’s supply grew while the broader pool contracted.
The numbers behind the move
On-chain trackers DefiLlama and stables.cool provided the figures. Both show Sui moving against the broader stablecoin market.
Dollar-pegged stablecoin supply across all networks stood at approximately $287.75 billion.
$USDC accounts for most of Sui’s stablecoin supply. Circle’s stablecoin represented $368.42 million on November 13, or 68.5% of the network’s total.
Sui’s native stablecoin, $USDsui, is another part of the picture, with supply of around $72 million.
That is slightly below its peak. $USDsui reached an all-time high of $80.1 million in mid-October 2026, before pulling back modestly.
Sui’s homegrown dollar token has therefore eased from its record. The overall stablecoin base still expanded, suggesting that inflows came largely from $USDC and other assets, rather than from $USDsui alone.
What has been happening on Sui
Several developments on the network coincide with the growth. The most significant structural change came in May 2026, when Sui introduced gasless transfers for its stablecoins.
Gas is the fee a blockchain charges to process a transaction. Gasless transfers remove that cost for the sender, making it more like sending a text than paying a toll to move dollars on Sui.
Decentralized finance, or DeFi, activity on Sui has also increased. DeFi refers to lending, trading and yield apps that run on smart contracts rather than through banks or brokers. Stablecoins are their main fuel.
Protocol fees on the network have risen along with stablecoin supply. Fees offer a rough indication of how much people are using the apps, rather than simply holding tokens in a wallet.
There is also a treasury component. The Sui Foundation uses yield from stablecoin reserves to fund buybacks of the $SUI token.
In other words, reserve dollars earn a return, and some of that return goes toward buying $SUI on the open market. This directly links stablecoin growth to the network’s native token.
Why the divergence matters
Stablecoin supply is one of crypto’s clearer signals. Prices can fluctuate with sentiment, but stablecoin balances show how many actual dollars people have chosen to move onto a particular chain.
The difference is large enough to stand out. Sui grew 10.33% while the market contracted 5.34%, a gap of more than 15 percentage points over 30 days.
The concentration in $USDC has both benefits and risks. With 68.5% of supply in a widely used stablecoin from a regulated issuer, the ecosystem has a familiar base asset that exchanges and institutions already understand.
But Sui’s stablecoin performance also depends heavily on a single issuer. If $USDC balances leave, the headline figure would drop quickly, and $USDsui is not yet large enough to make up the difference.
$USDsui is a variable to watch. Its rise to $80.1 million in mid-October showed demand for a network-native dollar, but its decline to around $72 million indicates that demand is not growing steadily.
The buyback mechanism adds another factor. If stablecoin reserves continue to grow, the yield available for $SUI buybacks could increase as well, potentially supporting confidence in the ecosystem’s longer-term plans.
The opposite is also true. A smaller reserve base would generate less yield to deploy, making the buyback program only as durable as the stablecoin inflows behind it.
Gasless transfers give Sui a feature that is easy to explain to users who are not interested in how blockchains work.
