Ethereum Foundation Proposes “EIL” for Unified Wallet Experience to Make it Like One Chain

The Ethereum Foundation has unveiled the Ethereum Interop Layer (EIL), a technical initiative intended to unify the user experience of Ethereum’s expanding rollup ecosystem, according to a recent proposal by the Account Abstraction team.

EIL promises a wallet-driven solution for seamless activity across Layer 2s, aiming to make Ethereum function as a single chain for users and developers.

EIL targets fragmentation in Ethereum’s layer 2 ecosystem

The emergence of rollups brought efficiency and affordable transactions, but introduced fragmentation for both assets and user experience. Navigating tokens that reside on Arbitrum, Base, Scroll, or Linea currently requires awareness of each chain’s specifics, the use of bridges and relayers, and constant manual interaction.

EIL seeks to eliminate these touchpoints by abstracting away the complexities and consolidating transaction logic inside the user’s wallet. With the interop layer, users can perform operations such as sending tokens, minting NFTs, or swapping assets across Layer 2s with a single click, without needing to identify or interact with individual chains.

Preserving Ethereum’s core security principles

EIL is built on top of the ERC-4337 account abstraction and guided by the principles outlined in the Trustless Manifesto, unveiled on Nov. 13. The system ensures that all cross-L2 actions are initiated and settled directly from user wallets, without new trust assumptions or intermediaries.

Essential values like self-custody, censorship resistance, privacy, and on-chain verifiability are maintained. The trust model stays minimal; users do not rely on third-party bridges or off-chain operators but instead transact under rules encoded in smart contracts and open-source wallet code.

Impact on users and developers

For users, EIL is designed to feel like “one Ethereum,” removing friction caused by fragmented balances and chain-specific procedures. Transactions such as cross-chain transfers, minting, and swapping are executed as if all assets coexisted on a unified ledger. Wallets become universal portals, with the selection of chains and coordination of asset movement handled invisibly behind the scenes, according to the Ethereum Foundation blog.

From a developer perspective, EIL centralizes interoperability within the wallet, bypassing the need for bespoke app-level integrations and accelerating the onboarding of new networks. As a result, dapps and wallets are multichain-native out of the box, enabling a familiar and streamlined experience for both new and existing rollups.

Ethereum’s next steps toward unified scalability

The Ethereum Interop Layer marks a move from transaction throughput achievements to improvements in interaction simplicity and cross-chain composability.

By giving users a window into the whole Ethereum ecosystem through a single wallet interface, EIL aims to restore the sense of unity and trustless operation that characterized Ethereum’s early vision. The initiative, from the team at the Ethereum Foundation, calls on wallet teams, dapp builders, and network designers to participate in its development and help realize the prospect of a seamless, singular Ethereum network.

Kalshi debuts ecosystem hub with Solana and Base

Kalshi debuts ecosystem hub with Solana and Base

The post Kalshi debuts ecosystem hub with Solana and Base appeared on BitcoinEthereumNews.com. Kalshi, the US-regulated prediction market exchange, rolled out a new program on Wednesday called KalshiEco Hub. The initiative, developed in partnership with Solana and Coinbase-backed Base, is designed to attract builders, traders, and content creators to a growing ecosystem around prediction markets. By combining its regulatory footing with crypto-native infrastructure, Kalshi said it is aiming to become a bridge between traditional finance and onchain innovation. The hub offers grants, technical assistance, and marketing support to selected projects. Kalshi also announced that it will support native deposits of Solana’s SOL token and USDC stablecoin, making it easier for users already active in crypto to participate directly. Early collaborators include Kalshinomics, a dashboard for market analytics, and Verso, which is building professional-grade tools for market discovery and execution. Other partners, such as Caddy, are exploring ways to expand retail-facing trading experiences. Kalshi’s move to embrace blockchain partnerships comes at a time when prediction markets are drawing fresh attention for their ability to capture sentiment around elections, economic policy, and cultural events. Competitor Polymarket recently acquired QCEX — a derivatives exchange with a CFTC license — to pave its way back into US operations under regulatory compliance. At the same time, platforms like PredictIt continue to push for a clearer regulatory footing. The legal terrain remains complex, with some states issuing cease-and-desist orders over whether these event contracts count as gambling, not finance. This is a developing story.

First family moves on from Wall Street as Eric Trump backs crypto

First family moves on from Wall Street as Eric Trump backs crypto

Eric Trump says crypto could actually save the U.S. dollar. Not kill it. Not weaken it. On Tuesday, just hours after ringing the Nasdaq opening bell for American Bitcoin’s public debut, a company where he’s got over $500 million stashed, Eric told the Financial Times that crypto is “arguably” the reason the dollar might stay alive. “Mining bitcoin here, and being financially independent and running a kind of financial revolution out of the United States of America…I think it arguably saves the US dollar,” he said. The timing wasn’t random. Eric’s comments came while the dollar was getting dragged. This year, it’s been tanking… fast. The cause? President Donald Trump’s trade war and his endless public jabs at the Federal Reserve, which just slashed interest rates again. The Fed cut rates yesterday, for the first time this year, right after Donald’s latest round of pressure. It’s not helping. Investors are losing confidence in what’s supposed to be the safest currency on Earth. Eric says crypto is fun, family is done with Wall Street Eric isn’t just pushing crypto from the sidelines. His family has gone full throttle into the space. We’re talking a Truth Social Bitcoin ETF, a Bitcoin treasury tied to Trump Media, and two meme coins; $MELANIA and $TRUMP. Eric defended both coins, saying they were meant to be “fun,” and explained why people are buying in: “They want to bet on a coin, or they want to bet on a player. They want to bet on a celebrity, or they want to bet on a famous brand. Or they just love somebody to death, and they want to buy, you know, a kind of small piece of them, via digital currency.” And Eric doesn’t give Wall Street any credit. At all. He made it clear that everything they’ve built was done without the help of big-name banks. “It’s almost like the ultimate revenge against the big banks and modern finance,” he said. That jab came after the Trump Organization filed a lawsuit against Capital One, accusing the bank of closing their accounts in 2021 for political reasons — something the bank denies. But Eric wasn’t done. “You realise you just don’t need them. And frankly, you don’t miss them.” He added that he wasn’t just referring to Capital One, but “all” of Wall Street’s major lenders and their “top people.” Stablecoins, trillions, and the White House betting on crypto Stablecoins have traditional banks spooked. They think cash might flow out of the banking system if coins like Tether or Circle offer better returns. And that fear isn’t fake. It’s growing, especially after Congress passed the first major crypto law in July. Now the White House wants stablecoin issuers to buy up a fat slice of the Treasury’s debt. Why? Because these crypto firms make money on the interest from the bonds they hold. Last year, Eric co-founded World Liberty Financial Inc. (WLFI), a crypto company that runs a stablecoin called USD1, pegged to the U.S. dollar. That project has serious family backing. Donald held 15.75 billion WLFI tokens at the end of 2024, based on official filings. At Wednesday’s trading price, that holding was worth over $3 billion. When asked about the family’s financial gain from crypto, Eric downplayed it. “If my father cared about monetising his life, the last thing he would have done is run for president, where all we’ve done is un-monetise our life.” Your crypto news deserves attention - KEY Difference Wire puts you on 250+ top sites
