Sui launches gas-free stablecoin transfers, targeting 1 billion users

Sui Network introduced gas-free stablecoin transfers on July 23, eliminating one of the biggest friction points in Web3 payments.

"The gas fee has been the single largest barrier to mainstream stablecoin adoption," the Sui Foundation said in a statement. "By removing it, we make sending value as easy as sending a message."

The feature lets users transfer stablecoins without holding SUI tokens for gas, with apps covering transaction costs instead. Transfers can be initiated via email, link or QR code — no wallet address required. The system uses Sui's programmable transaction blocks to batch 1,024 actions into a single transaction, reducing overhead for complex payment flows.

The move targets the $180 billion stablecoin market, where high gas fees on Ethereum and other L1s have limited everyday payment use cases. Sui, which processes transactions in 390 milliseconds with parallel execution, aims to capture a share of stablecoin volume currently dominated by Ethereum and Tron. USDT on Tron alone accounts for more than $50 billion in supply, according to DefiLlama.

The gas-free model extends beyond simple transfers. Sui's zkLogin lets users authenticate with Google credentials, eliminating seed phrase management. The network's Walrus Protocol enables on-chain data storage, while the Seal encryption system gives users granular control over data access. Together, these features create a stack where users never need to interact with a blockchain directly.

Sui's total value locked stood at $1.2 billion as of July 23, according to DefiLlama, with the network processing roughly 5 million daily transactions. The gas-free stablecoin feature could accelerate TVL growth by attracting users who previously avoided DeFi because of transaction costs.

The announcement follows the launch of Hashi, a protocol that lets Bitcoin holders earn yield on Sui without wrapping their BTC. Together, the two features give Sui a dual path to attract both Bitcoin liquidity and stablecoin payment flows.

For stablecoin issuers and DeFi protocols, Sui's gas-free model could shift where liquidity concentrates. If users no longer need to factor gas costs into transaction decisions, the network with the lowest friction may capture an outsized share of payment volume. SUI traded at $1.84 as of 14:30 UTC, up 4.2% in the past 24 hours, according to CoinGecko.
