The Sui blockchain has moved nearly $65 billion in stablecoins in five days, the payoff from a protocol change that made those transfers cost nothing. The figure measures transfer throughput over the window, and it lands as Mysten Labs pitches the network as a replacement for traditional payment rails.
CertiK Skynet, a data dashboard by the blockchain security firm, reported that Sui settled close to $65 billion in stablecoin transfers since June 10 without users paying fees. The same data put cumulative stablecoin volume on the network above $2.27 trillion since early 2024. The catalyst was a protocol-level change that Mysten Labs, Sui's founding contributor, rolled out on May 20, dropping stablecoin transfer fees to $0.00 and removing the need to hold the native SUI token to move funds.
The $65 billion measures transfer volume cleared over a five-day window. Sui's standing stablecoin supply sits near $470 million, per DefiLlama, which ranks the chain outside the 15 largest by stablecoin market capitalization. A sub-$500 million float turning over tens of billions in days reflects dollars recirculating as payments, the behavior the fee-free design was built to encourage.
Sui's change covers single and batched peer-to-peer transfers of supported stablecoins, with the network absorbing the gas cost. Supported assets at launch included USDC, USDY, AUSD, FDUSD and the Bridge-issued USDsui and Ethena-issued suiUSDe. Mysten Labs framed the mechanism as structural rather than promotional, calling it "not a subsidy, sponsorship program, or temporary promotional initiative."
