In a significant development for regulated cryptocurrency investment vehicles, KraneShares has taken a concrete step toward launching a multi-asset ETF by filing Pre-Effective Amendment No. 3 for its proposed Coinbase 50 Index ETF. This filing, dated April 22, 2026, indicates notable progress in bringing a diversified, institutionally-focused crypto product to market. The fund is designed to track the performance of the top 50 digital assets by market capitalization and trading volume on the Coinbase platform. A key detail from the amendment is the confirmed retention of XRP within the fund's basket of assets, a decision that carries weight given the asset's complex regulatory history. This inclusion suggests a calculated assessment by the fund's architects regarding XRP's longevity and institutional acceptability. The move by KraneShares underscores a clear market trend: growing institutional demand is shifting beyond single-asset cryptocurrency funds, like Bitcoin or Ethereum ETFs, toward products that offer broad-based exposure to the digital asset ecosystem. A multi-asset ETF mitigates single-asset volatility and provides a more holistic bet on the growth of the cryptocurrency sector as a whole. It represents a maturation point for crypto in traditional finance, allowing investors to gain diversified exposure through a single, regulated security. This development occurs against a backdrop of ongoing evolution for Coinbase itself, which, as the index provider and primary trading venue for the underlying assets, continues to navigate its own regulatory landscape. The advancement of this ETF, despite external challenges, highlights the persistent institutional push to integrate digital assets into conventional portfolio strategies, paving the way for a new era of accessible and diversified crypto investment.

KraneShares Advances Coinbase 50 Index ETF with XRP Inclusion

KraneShares has filed Pre-Effective Amendment No. 3 for its proposed Coinbase 50 Index ETF, signaling progress toward a regulated multi-asset crypto product. The ETF aims to track the top 50 digital assets, with XRP notably retained in the basket. This move underscores growing institutional demand for diversified crypto exposure beyond single-asset funds.

The filing coincides with Coinbase's legal challenges in New York over its prediction markets business. Meanwhile, KraneShares hosted its Technology Investor Day at Nasdaq MarketSite, highlighting the convergence of traditional finance and digital assets. Market participants view each regulatory step as critical for mainstream adoption.

A successful launch could create a new benchmark for crypto investing, offering investors a compliant gateway to the asset class. The inclusion of XRP—despite its regulatory history—demonstrates the index's comprehensive approach to market representation.

Base's Azul Upgrade Slashes Withdrawal Times to One Day

Base, Coinbase's Ethereum Layer 2 solution, has deployed its "Azul" upgrade in testnet, marking its first independent software overhaul. The update introduces a multiproof system combining hardware-based secure enclave proofs and zero-knowledge proofs, enabling asset withdrawals in as little as one day when consensus is achieved between both methods.

The infrastructure shift includes phasing out legacy clients in favor of a unified "base-reth-node" execution client and a new "base-consensus" module built on Kona. This architectural streamlining coincides with Base's growing dominance among Ethereum L2s, now processing more transactions than Arbitrum.

With mainnet integration scheduled for May 13, the upgrade follows a rigorous security audit that uncovered no critical vulnerabilities. The development team has implemented a permission system allowing zero-knowledge proofs to take precedence in certain scenarios, further optimizing withdrawal efficiency.
