TL;DR
- Sui’s stablecoin supply is approaching $500 million after remaining largely stable for months.
- The network has processed more than $65 billion in fee-free stablecoin transfers since June 10 following a protocol upgrade.
- Meanwhile, cumulative stablecoin transaction volume has exceeded $2.27 trillion since early 2024, highlighting growing payment activity despite relatively flat stablecoin balances.
Sui’s stablecoin supply is nearing $500 million, with DeFiLlama data placing the figure around $478 million. While the amount remains well below the network’s previous peak, activity across Sui’s payment infrastructure continues to expand.
The network’s stablecoin balance reached approximately $1.6 billion in May 2025 before declining sharply. By the end of the first half of 2026, supply had fallen to around $492 million, representing a decline of roughly 69%. Since then, the metric has remained relatively steady rather than returning to its previous highs.
That stability contrasts with Sui’s rapidly increasing transaction activity. Mysten Labs, the company behind Sui’s development, introduced a protocol-level feature that eliminated fees for supported stablecoin transfers. The update also removed the need for users to hold SUI simply to move certain stablecoins across the network.
The feature currently supports seven assets, including USDC, USDsui, SuiUSDe, AUSD, FDUSD, USDB and USDY. According to figures tracked by blockchain security firm CertiK, these fee-free rails have processed more than $65 billion in stablecoin transfers since June 10.
Sui Stablecoin Activity Gains Momentum
The broader network figures provide additional context. Sui has processed more than $2.27 trillion in cumulative stablecoin transaction volume since early 2024, covering roughly 16 billion transactions. CertiK has not provided a detailed breakdown of the $65 billion figure by individual stablecoin or counterparty.
Mysten Labs co-founder Adeniyi Abiodun has described the fee reduction as a way to remove unnecessary friction from stablecoin payments. From a crypto market perspective, lowering transaction costs can make blockchain-based settlement more competitive for applications that require frequent transfers.
Other developments are also expanding Sui’s infrastructure. Its Hashi bridge testnet, launched on July 22, reportedly processed more than 1.1 million deposits and over 165,000 withdrawals during its first three weeks.
The difference between stablecoin supply and transaction volume is important. A blockchain can process substantial payment activity without accumulating the same value in its resident stablecoin balances. Fee-free transfers may encourage users to move assets quickly between wallets and applications instead of keeping funds idle on the network.
