Stablecoin

Sui has introduced protocol-level gasless stablecoin transfers, allowing peer-to-peer payments in supported stablecoins without users needing to pay gas fees or hold a SUI balance. The rollout includes USDsui, SuiUSDe, USDC, and USDY, as the network continues to frame stablecoins as a core part of its payments strategy.

Binance logged a 40.0644 million USDT net inflow over the past hour, indicating more USDT entered the exchange than left during that window. Such stablecoin inflows are often watched as a proxy for potential buying power, though the transfers could also relate to internal operations or liquidity activity. Traders typically look for follow-through across multiple hours and confirmation via spot volume before treating the signal as directional.

Sui introduced protocol-level gasless transfers for supported stablecoins on May 20, 2026, enabling $0.00-fee sends without users needing to hold SUI for gas.

As of May 22, 2026 (09:37 UTC), SUI traded at $1.1032 and was down -1.81% on the week.

On May 19, Ripple said Ripple Prime integrated with EDX Markets and EDXM International to add EDX liquidity for institutional clients across digital asset spot and perpetual futures markets. The setup provides a single prime-brokerage access point that combines trading, credit intermediation, net settlement, and collateral and margin workflows. Ripple also said the collaboration is intended to support future use of its U.S. dollar-backed stablecoin RLUSD for settlement and collateral on EDX.

Evernorth argues XRP and RLUSD fill different roles on the XRP Ledger, with XRP used as a neutral bridge asset for routing trades and RLUSD aimed at dollar-denominated transactions. In a May 20 Evernorth blog post, chief business officer Sagar Shah said issuer-linked constraints can make stablecoins less suited for universal routing across markets. He added that XRP’s function also extends to liquidity pools, collateral use, and XRPL escrow-based settlement.

Binance saw a net USDT outflow of $46.15 million over the past hour, a measure that compares withdrawals against deposits for the same period.

Her planned exit comes as key crypto rule areas—including stablecoins, tokenization, and exchange registration—remain unsettled.
