When a blockchain leans into a stablecoin strategy, it typically signals a more forward-looking shift.
The idea is pretty straightforward. Payments are a trillion-dollar global market, and Layer-1 chains are clearly aiming to position themselves in the middle of it. Stablecoins are becoming the core settlement layer in this shift. As a result, much of the recent market activity is increasingly revolving around this narrative.
Additionally, Sui has rolled out gasless stablecoin transfers. It is a protocol-level upgrade that lets users and businesses send supported stablecoins peer-to-peer without paying gas fees or needing to hold a separate SUI token balance. In simple terms, stablecoin transfers on Sui are now basically $0 in fees.
Notably, the feature has been launched with support for stablecoins including USDsui, SuiUSDe, USDC, and USDY.
From a technical standpoint, this allows institutional users to move across these stablecoins with zero gas fees on supported transfers. With over 68% of Sui’s [SUI] stablecoin supply in USDC, its inclusion makes sense while further strengthening Sui’s overall stablecoin ecosystem. In fact, it is up by 9% in Q2, adding roughly $50 million in net inflows. More importantly, this lines up with SUI’s 25%+ rally too.
Naturally, the question becomes – Is Sui’s technical strength now reflecting stronger on-chain fundamentals, with recent stablecoin developments pushing SUI closer to being “Wall Street ready?”
SUI’s transaction growth signals rising on-chain competition
As noted earlier, SUI’s stablecoin model is centered around global payments infrastructure.
To assess its impact on DeFi positioning, the key focus is whether the network is already seeing meaningful growth in on-chain activity, especially transaction counts, and what that signals for potential shifts in institutional flows and overall ecosystem momentum.
Notably, the impact could be significant. As the chart below shows, SUI’s transaction count has totalled around 1.6 billion since Q2 2025. Although QoQ activity has declined, it is still processing higher transaction volumes than Ethereum [ETH], with SUI’s Q2 2026 count at 215 million versus Ethereum’s 117 million.
In essence, SUI’s technical strength reflects sustained real usage on-chain.
Against this backdrop, making stablecoin transactions free on the network is clearly strategic. With already strong on-chain activity, fee-free transfers could further amplify this trend, making a 400 million+ transaction quarter on SUI increasingly likely.
More importantly, this could mark the start of a broader trend. With SUI already leading altcoins in both technicals and fundamentals, the stablecoin model may further widen that gap, reinforcing its push towards institutional adoption and strengthening its edge in the growing DeFi competition.
