0x will support Robinhood Chain with RFQ-based liquidity for tokenized stock tokens and cross-chain swap access for users moving assets across supported networks.

SAN FRANCISCO, July 1, 2026 /PRNewswire/ — 0x, a software infrastructure company whose APIs power payments, trading, and tokenized asset products across the onchain financial system, today announced Day 1 support for Robinhood Chain, Robinhood’s new blockchain built for financial services and tokenized real-world assets.

At launch, 0x will provide two core infrastructure layers for Robinhood Chain: RFQ-based liquidity for Stock Tokens and cross-chain swap access through the 0x Cross-Chain API. As across-chain swap provider for the Robinhood Wallet, 0x will enable users to move assets to and from Robinhood Chain across supported networks in a single transaction.

Robinhood Chain is designed to bring tokenized real-world assets onchain, including equities and ETPs, with 24/7 trading availability and infrastructure purpose-built for tokenized financial markets. 0x’s support extends its long-standing role powering Robinhood’s onchain swap infrastructure into a new layer of liquidity and cross-chain access for Robinhood Chain.

“Robinhood Chain is a meaningful step toward tokenized equities becoming part of mainstream financial infrastructure. 0x has powered Robinhood’s swap infrastructure for years, so extending that work to their new chain and the stock tokens they’re bringing onchain is a natural next step in a partnership we’ve built over time.” – Amir Bandeali, CEO at 0x

RFQ Liquidity for Tokenized Stock Tokens
0x’s RFQ infrastructure is live on Robinhood Chain at launch, enabling liquidity for Stock Tokens through a quote-based model. Instead of relying on open AMM pools, RFQ connects Robinhood Chain to professional market makers who can provide direct pricing and inventory for tokenized assets.

This model is designed to support the controls required for tokenized equity markets while giving users access to competitive execution. Trade and own stock tokens for top US companies supported at launch, with USDG as the primary base pair, on 0x’s RFQ venue.

The primary market maker participating through 0x RFQ is Tokka Labs.

Cross-Chain Access to Robinhood Chain
The 0x Cross-Chain API will support Robinhood Chain from launch, enabling users on supported networks including Ethereum, Arbitrum, Base, Solana, and others to move assets to and from Robinhood Chain without separately managing bridges, intermediary tokens, or multi-step transactions.

Through 0x, users will be able to buy and sell Stock Tokens on Robinhood Chain using assets from supported networks, sell tokenized stock tokens back into supported assets on other networks, and bridge supported stablecoins such as USDG.

The Robinhood Chain integration builds on the same 0x Cross-Chain API stack that reached general availability on July 4, following a private beta with more than $230 million bridged and support for 25+ blockchains across 12+ bridge providers. With Robinhood Chain, 0x extends its one-API model for multi-chain execution to tokenized asset markets from Day 1.

Expanding 0x’s Role in Robinhood Wallet‘s Onchain Infrastructure
0x has powered Robinhood Wallet‘s swap infrastructure across EVM chains since the early days of Robinhood’s onchain wallet. Robinhood Chain expands that relationship from swap routing to liquidity and cross-chain infrastructure for Robinhood Chain..

Across its broader partner ecosystem, more than $400 billion in total volume has flowed through 0x APIs.

“0x has been a trusted Robinhood Wallet partner since 2023, making them an obvious choice for a day one integration on Robinhood Chain,” said Gaëtan Thabot, Director of Partnerships at Robinhood Crypto. “The company’s leadership in the space has been proven time and time again as evident by their growing network and the number of supported assets. We look forward to growing our relationship.”

Availability
0x Swap API and Cross-Chain API support for Robinhood Chain will be live at launch. Developers and teams building on Robinhood Chain can access documentation, integration guides, and API credentials at 0x.org, or contact the 0x team to scope integrations. To explore integrating tokenized asset liquidity, please reach out to the 0x team for more information.

About 0x
0x is the infrastructure layer for moving value in the onchain financial system. As financial activities migrate from legacy rails to onchain networks across payments, stablecoins, tokenized assets, and agentic commerce, 0x provides the swap and cross-chain APIs that give developers, fintechs, and financial institutions programmable access to digital assets wherever they live. More than 500 products are built on 0x, with $400B+ in volume moved and 200M+ transactions executed since launch. Customers include Coinbase, Robinhood, MoonPay, Phantom, MetaMask, and Privy.

Founded in 2017 by Amir Bandeali and Will Warren, 0x has raised $109M in total from credible investors including Pantera Capital, Greylock, and Coinbase Ventures.

METRO CHICAGO, Ill., July 1, 2026 /PRNewswire/ — Calamos Investments®* has announced monthly distributions and sources of distributions paid in July 2026 to shareholders of its seven closed-end funds (the Funds) pursuant to the Funds’ respective distribution plans.

The following table provides estimates of Calamos Global Total Return Fund’s, Calamos Global Dynamic Income. Fund’s, Calamos Dynamic Convertible and Income Fund’s, Calamos Convertible Opportunities and Income Fund’s, and Calamos Convertible and High Income Fund’s distribution sources, reflecting YTD cumulative experience. The Funds attribute these estimates equally to each regular distribution throughout the year.

Regarding Calamos’ remaining two closed-end funds, which operate under a managed distribution policy: The information below is required by an exemptive order granted to the Funds by the US Securities and Exchange Commission and includes the information sent to shareholders regarding the sources of the Funds’ distributions.

The following table sets forth the estimated amount of the sources of distribution for purposes of Section 19 of the Investment Company Act of 1940, as amended, and the related rules adopted thereunder. The Funds estimate the following percentages, of their respective total distribution amount per common share, attributable to (i) current and prior fiscal year net investment income, (ii) net realized short-term capital gain, (iii) net realized longterm capital gain and (iv) return of capital or other capital source as a percentage of the total distribution amount. These percentages are disclosed for the current distribution as well as the fiscal YTD cumulative distribution amount per common share for the Funds. The following table provides estimates of each Fund’s distribution sources, reflecting YTD cumulative experience. The Funds attribute these estimates equally to each regular distribution throughout the year.

You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s plan.

If the Fund(s) estimate(s) that it has distributed more than its income and capital gains, a portion of your distribution may be a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with ‘yield’ or ‘income’.

The amounts and sources of distributions reported in this 19(a) notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for accounting and tax purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099 DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Return figures provided below are based on the change in the Fund’s Net Asset Value per share (“NAV”), compared to the annualized distribution rate for this current distribution as a percentage of the NAV on the last day of the month prior to distribution record date.

While the NAV performance may be indicative of the Fund’s investment performance, it does not measure the value of a shareholder’s investment in the Fund. The value of a shareholder’s investment in the Fund is determined by the Fund’s market price, which is based on the supply and demand for the Fund’s shares in the open market. Past performance does not guarantee future results.

Monthly distributions offer shareholders the opportunity to accumulate more shares in a fund via the automatic dividend reinvestment plan. For example, if a fund’s shares are trading at a premium, distributions will be automatically reinvested through the plan at NAV or 95% of the market price, whichever is greater; if shares are trading at a discount, distributions will be reinvested at the market price through an open market purchase program. Thus, the plan offers current shareholders an efficient method of accumulating additional shares with a potential for cost savings. Please see the dividend reinvestment plan for more information.

Important Notes about Performance and Risk
Past performance is no guarantee of future results. As with other investments, market price will fluctuate with the market and upon sale, your shares may have a market price that is above or below net asset value and may be worth more or less than your original investment. Returns at NAV reflect the deduction of the Fund’s management fee, debt leverage costs and other expenses. You can purchase or sell common shares daily. Like any other stock, market price will fluctuate with the market. Upon sale, your shares may have a market price that is above or below net asset value and may be worth more or less than your original investment. Shares of closed-end funds frequently trade at a discount which is a market price that is below their net asset value.
