When a blockchain builds on a stablecoin strategy, it generally signals a more future-focused shift.
The idea is quite simple. Payments is a multi-trillion dollar global market, and layer 1 chains are clearly aiming to position themselves in the middle of it. Stablecoins become the central settlement layer in this shift. As a result, much of the recent market activity increasingly revolves around this narrative.
Additionally, Sui has rolled out gasless stablecoin transfers. This is a protocol-level upgrade that allows users and businesses to send supported stablecoins between peers without paying gas fees or needing to hold a separate SUI token balance. Simply put, stablecoin transfers on Sui now cost virtually $0 in fees.
Notably, the feature launched with support for stablecoins including USDsui, SuiUSDe, USDC, and USDY.
From a technical perspective, this allows institutional users to move between these stablecoins without 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 grew 9% in the second quarter, adding about $50 million in net inflows. More importantly, this also matches SUI’s over 25% rally.
Naturally, the question becomes: is Sui technical strength now reflects stronger on-chain fundamentals, with recent stablecoin developments pushing SUI closer to being “Wall Street ready?”
SUI Transaction Growth Signals Growing On-Chain Competition
As previously noted, SUI’s stablecoin model is focused on global payments infrastructure.
To assess its impact on DeFi’s positioning, the focus is on whether the network is already experiencing significant growth in on-chain activity, particularly in the number of transactions, and what this signals for potential changes in institutional flows and overall ecosystem dynamics.
The impact could notably be significant. As shown in the chart below, SUI’s transaction count stands at approximately 1.6 billion since Q2 2025. Although QoQ activity has declined, it still processes higher transaction volumes than Ethereum (ETH), with SUI’s transaction count in Q2 2026 being 215 million compared to Ethereum’s 117 million.
Essentially, SUI’s technical strength reflects real, sustained on-chain usage.
In this context, making stablecoin transactions free on the network is clearly strategic. With on-chain activity already strong, fee-free transfers could further amplify this trend, making a quarter of 400 million+ transactions on SUI increasingly likely.
More importantly, it could mark the start of a larger trend. While SUI already leads altcoins both technically and fundamentally, the stablecoin model could further widen this gap, strengthening its push towards institutional adoption and strengthening its advantage in the growing competition from DeFi.
