bitcoinethereumnews.com reports that the Cardano Foundation has added ADA support to the official x402 software kit, providing developers with code to build apps and AI agents that pay for online services in the token. The payment facilitator behind this integration has only ever run on a test network and has never been on the mainnet.
How the market reacted
Whalio's own Binance spot order flow for ADA, measured when this story was written up on 23 September 2026. Not the outlet's figures.
ADA trades at $0.2543 with a 1-hour buy ratio of 51.2%, contrasting with a 4-hour ratio of 44.1% and a 24-hour ratio of 48.6%. Short-term buying pressure is building relative to the recent 4-hour trend, though the 24-hour average shows a near-even split between buyers and sellers. The volume delta reflects this shift, showing a positive $47,818 in the last hour against negative figures of -$1,307,546 over 4 hours and -$2,119,379 over 24 hours. Cumulative volume delta closed at -$3,177,852, indicating that net selling has dominated the day despite the recent hourly surge.
The latest daily buy ratio of 45.6% sits at the 5th percentile of the last 322 days, against a median of 49.2% - among the weakest buying days it has had.
