Petrobras, Brazil’s state-controlled energy company, is testing Cardano to track sustainable aviation fuel benefits and prevent double-counting.The Cardano Foundation said on Sept. 30 that an ongoing research and development collaboration had delivered applications for sustainable aviation fuel (SAF) and Diesel R, Petrobras’ renewable fuel brand.The SAF project addresses a problem that arises when the buyer of a fuel’s environmental benefit is different from the buyer or user of the fuel itself. Its Book-and-Claim model lets an airline, company, or passenger receive that benefit even when the SAF is produced or used elsewhere.Petrobras developed the SAF platform with PUC-Rio University’s Ledger…

Standard Chartered expects Ethena’s ENA token to rise about sevenfold by 2028, provided the protocol can rebuild its shrinking synthetic-dollar business.The bank initiated coverage of ENA with a $2 year-end 2028 target, up from about $0.28 currently. It forecasts the token reaching $0.42 at the end of 2026 and $1.10 in 2027 before accelerating further the following year.The projection would leave ENA outperforming Standard Chartered’s expected gains for both Bitcoin and Ethereum over the same period. But reaching it requires Ethena to reverse a contraction that has cut USDe supply by more than half from its peak and expand far…

Hackers behind Bitget’s $387.5 million breach are turning to Zcash’s privacy features to hide the stolen funds as crypto firms increasingly block other escape routes.About 2,746 ZEC worth roughly $3.9 million was transferred Wednesday into Zcash’s Ironwood shielded pool through three transactions, according to on-chain activity flagged by blockchain investigator ZachXBT. The amount represents about 15% of the 18,917 ZEC stolen from the exchange.Bitget Attackers Fund Movement into Zcash’s Shielded Pool (Source: ZachXBT)The transfers complicate Bitget’s recovery effort because transactions inside Ironwood can conceal senders, recipients, and amounts, breaking the public transaction trail investigators use to follow stolen assets.

Kalshi is ending a trader-volume incentive program nearly a year early as scrutiny of activity in its crypto markets intensifies.The prediction-market operator told the Commodity Futures Trading Commission (CFTC) that its Volume Incentive Program will terminate no earlier than Oct. 13, according to a Sept. 28 filing. The program had previously been scheduled to run until Oct. 1, 2027, making the change a significant acceleration of its planned end date.The decision comes as Kalshi faces questions over trading patterns in its perpetual futures markets. The CFTC has reportedly examined activity after researchers identified repetitive trades around fixed dollar amounts, including…

Aave’s proposed institutional lending business would put crypto collateral on both sides of the financing chain. Institutions would pledge Bitcoin or Ether for dollar loans, while the organization governing the Aave lending protocol would initially borrow those dollars against a separate pool of its own crypto assets.Aave Labs’ September 30 clarification identifies an Aave Labs entity as the contractual lender and confirms that the DAO-funded route would pay prevailing Aave V3 stablecoin borrowing rates. That makes the borrower’s ability to meet a margin call only one test of the business. The funding position could face its own collateral pressure or…

ApeX offers vaults, staking, and bots for passive yield. Protocol Vaults earn from daily liquidation-fee revenue. Grid bots automate trades across USDT perpetual markets. Most of the attention a perpetual exchange gets goes to the people trading 100x. Most of the capital on one does not belong to them. ApeX Omni has quietly built a second layer for everyone else: a set of products where the return comes from the platform’s own activity, from other traders’ skill, or from a rules-based bot, and where the user’s job is to allocate rather than to trade. Four pieces make up that layer,…

UK crypto firms can now apply for authorization as of Sept. 30, bringing Bitcoin holders closer to a rulebook that will treat coins pledged as qualifying borrowing collateral differently from coins transferred into lending for yield. The distinction could matter when a platform fails: safeguarded assets and a contractual promise to return equivalent coins give customers different starting points for seeking recovery.The Financial Conduct Authority now allows firms to apply for authorization or vary their permissions through its Connect system. But the safeguards in the rules it finalized June 30 are forthcoming, with the new regime expected to begin Oct.…

Stablecoin card spending is accelerating to record levels, but the payment rail remains a fraction of the traditional card market.Paymentscan tracked about $1.17 billion in spending through Sept. 30, already above August’s completed total and the highest monthly figure in its displayed series.Cuy Sheffield, head of Visa’s crypto unit, described stablecoin-linked cards as being in “hyper growth mode,” as issuers increasingly connect dollar-denominated tokens to existing card networks rather than wait for merchants to accept crypto directly.Notably, the growth has continued even without a corresponding increase in payment frequency. Paymentscan recorded 11.0 million transactions in September, down from 11.07 million…

Robinhood Chain, an Ethereum layer-2 network, kept producing blocks throughout its Sept. 4 disruption. A new full-day measurement corrects CryptoSlate’s earlier report that block production stopped for at least 14 minutes. Separate public-data analysis found that successful transactions through busy apps fell sharply for about 40 minutes, leaving users with a real disruption despite the continuing blocks.Glass Hull’s Sept. 29 measurement counted 854,255 blocks across all 1,440 minutes of Sept. 4 UTC. The longest gap between consecutive recorded block timestamps was two seconds. In the minute beginning 12:57 UTC, the reported start of the supposed halt, the chain produced 592…
