Binance logged a 40.0644 million USDT net inflow over the past hour, indicating more USDT entered the exchange than left during that window.

Traders typically look for follow-through across multiple hours and confirmation via spot volume before treating the signal as directional.

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.

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.
