Top Crypto News This Week: Mantle Integration, Jupiter Announcement, GENIUS Act, and More

Several headlines are in the pipeline for the top crypto news this week. Spanning several ecosystems, crypto markets, and key events will drive volatility for different tokens this week.

Traders and investors can monitor the following headlines to front-run events and ecosystem-specific volatility.

Mantle Integration Announcement

This week, one of the top crypto news stories is Mantle Network’s integration announcement. After the Tectonic Upgrade was implemented in March 2024 and the Mainnet Alpha launch in July 2023, the Mantle ecosystem will undergo a planned update.

Recently, Mantle Network integrated with EigenDA, reducing transaction fees significantly while improving transaction speed. As Mantle builds, it also integrates Stargate, enabling seamless, bridgeless transfers.

Now the network has another integration in the pipeline, though details remain scarce.

“Intern hearing things…Very big integration potentially happening next week on Mantle,” a Mantle Network intern shared on X last week.

Data on CoinGecko shows Mantle Network token’s price is down by 0.5% in the last 24 hours. As of this writing, MNT was trading for $0.7298.

Jupiter Product Announcement

Another expected headline in the top crypto news this week is Jupiter Exchange’s product announcements. In a post last week, the Solana-based DEX teased a major product announcement by a Jupiter executive.

“Accelerate with Jupiter. Next week, catch Kash on the main stage with a banger product announcement (or two),” Jupiter said on Friday.

Some speculate that the prospective announcement relates to their recent partnership with Sanctum for a SOL-based debit card, expanding DeFi offerings.

Meanwhile, others say it concerns highlights by another Jupiter executive, @weremeow on X, about a major Jupiter event, including a product reveal and DAO discussion. Meanwhile, a key conversation in the Jupiter ecosystem concerns the JupNet.

“Jupnet is a really big lift across the board, lots of research to be done across the board, proof of concepts to be developed in lieu of a good design, followed by lots of productizing. With Jupnet, we hope to add some special elements to the crypto space,” @weremeow noted in a post.

The Jupiter executive explained JupNet in a detailed post, citing a Catstanbul 2025 announcement. JupNet is an omnichain network tackling blockchain interoperability with a decentralized state of truth, omnichain ledger, and aggregated decentralized identities (ADIs).

The team has iterated core designs and enhanced the Solana Virtual Machine (SVM) for better transaction handling. They held their first offsite in April 2025 in San Francisco.

Upcoming steps include DOVE layer audits, internal tests, and a technical paper release. These aim to transform on-chain interactions with features like passkeys and MFA.

Avalanche London Summit

Also, this week’s top crypto news story is the Avalanche Summit in London, expected to start on Tuesday, May 20. The sentiment is that the Avalanche network might make major announcements during the summit.

Meanwhile, according to the Avalanche Foundation, more than 30 million contracts have been deployed across all indexed Avalanche Layer-1 (L1) networks. Approximately 10 million were deployed in the past month alone, with accelerating activity across the Avalanche network.

“Looks like the ‘big wave’ is coming ahead of Avalanche Summit London,” Avalanche Viet Nam remarked in a post.

Meanwhile, BeInCrypto data shows AVAX was trading for $21.49 as of this writing, down by nearly 6% in the last 24 hours.

US Senate to Pass Stablecoin Legislation

There is also speculation that the US Senate will pass stablecoin legislation this week. This comes after Senator Bill Hagerty announced that the Senate is ready to pass the GENIUS Act.

“Next week, the Senate will make history when we pass the GENIUS Act that establishes the first-ever pro-growth regulatory framework for payment stablecoins. This bill will cement US dollar dominance, protect customers, increase demand for US treasuries, and ensure that innovation in the digital asset space is in the hands of the United States of America, not our adversaries,” Senator Hagerty wrote.

This legislation would mark a game-changing bill, establishing the first comprehensive regulatory framework for payment stablecoins.

Further, this historic move is set to transform the $244 billion stablecoin market. It would ensure backed reserves, anti-money laundering measures, and consumer protections.

The bill seeks to curb Big Tech’s control over digital money, demanding special approval before giants like Meta can issue their own stablecoins. This is noteworthy because it is the first step toward true financial decentralization backed by federal law.
