Cardano Climbs 20% as Petrobras Pilot and x402 Join
Cardano (ADA)

cryptocurrency.com.tr reports that Cardano has risen nearly 20% following two adoption developments within a single week. Brazil’s state oil giant Petrobras is piloting the blockchain to verify fuel emissions claims for sustainable aviation fuel and Diesel R. In a separate move, Cardano joined the x402 SDK, enabling AI agents to pay in ADA. Despite these adoption stories, the announcements did not generate immediate token demand.
The token currently trades at $0.2468, having flattened after its weekly run. It remains trapped below a long-term descending trendline that has held for nearly nine years. The first major level to reclaim is $0.34.
A break of that structure would reveal resistance around $0.74, followed by $0.95 and $1.20. Claude AI predicts the token faces a critical test against this long-standing resistance.
How the market reacted
Whalio's own Binance spot order flow for ADA, measured when this story was written up on 1 October 2026. Not the outlet's figures.
ADA trades at $0.2466 with a 1-hour buy ratio of 47.1%, indicating slightly more selling than buying in the short term. The 4-hour buy ratio sits at 51.9%, showing a marginal shift toward buying pressure over a slightly longer timeframe. Over 24 hours, the buy ratio is 48.4%, suggesting a near-even split between buyers and sellers. The 1-hour volume delta is -$45,960, reflecting net selling in the immediate term. However, the 4-hour volume delta is +$262,711, showing net buying over the medium term. The 24-hour volume delta is -$1,153,839, indicating that net selling has outweighed buying over the full day.
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.
Was that an ordinary day?
The same Binance spot measurements for ADA, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 50.7%, making the current 24-hour ratio of 48.4% slightly below the weekly norm. Volume was 0.75x the average, indicating a quieter trading day than usual. The coin saw net buying on 5 of 7 days, with a total volume delta of +$3,704,367 for the period. The price increased by 3.4% over the eight-day window. This suggests a generally positive but subdued trading environment compared to the immediate hourly fluctuations.
