Rumble Fish secures $131K grant to build Soroban-first block explorer for Stellar network

Rumble Fish has been awarded a $131,200 grant from the Stellar Community Fund to build a Soroban-first Block Explorer for the Stellar network's smart contract platform. The grant was awarded through SCF's 41st funding round. The project addresses a critical gap in the Soroban ecosystem, where current block explorers display smart contract data in raw, technical formats that are difficult to interpret. Rumble Fish's solution will provide human-readable transaction details, contract pages and decoded events through a React-based frontend. The three-phase project will build a full-stack infrastructure including data ingestion, a public interface and production-grade deployment on AWS. The explorer aims to improve transparency and accessibility for developers, investors and users interacting with Soroban's decentralised finance applications and smart contracts.

Lava Network integrates Stellar, bringing high reliability RPC access to financial blockchain ecosystem.

Lava Network integrates Stellar, bringing high reliability RPC access to financial blockchain ecosystem. April 7, 2026 8:00 AM Table of contents Stellar is now operational on Lava Network which is a major achievement in increasing the reliability of infrastructure in blockchain based financial applications. The integration adds Remote Procedure Call (RPC) access to both the mainnet and the testnet of Stellar, allowing developers and institutions to connect to the network more effectively. The action indicates an increasing need to have strong infrastructure that can sustain real life financial transactions on blockchain systems. Through the decentralised infrastructure layer of Lava Network, Stellar hopes to provide uninterrupted availability and on demand access of data to applications powered by its ecosystem. Powering real world financial activity. Stellar has traditionally positioned itself as a blockchain that can be used in real world financial applications. Its network has a vast variety of services, such as cross border payments, remittances, stablecoin transactions and connectivity with traditional financial systems. These applications involve constant availability of validated data and any little interference would affect the transactional patterns and customer confidence. This essential need is met by the integration with Lava Network which strengthens the backbone on which Stellar works. Stellar based financial applications are commonly used in those areas where stable financial infrastructure is not readily available, so reliability is not only a technical requirement but also a practical one. With the increased use of blockchain in the payment and settlement industry, there is an increasing need to have reliable infrastructure. The partnership between Stellar and Lava Network indicates a wider trend in the industry of focusing more on the back end resilience to enable front end innovation. Lava Network's infrastructure advantage. Lava Network offers a decentralized infrastructure solution by providing multi provider RPC services. It is a way of saying that rather than using one data provider, requests are directed to a number of providers enhancing reliability and performance. The traffic is dynamically allocated in the system depending on the quality of service, where the most critical workloads are assigned to the most successful providers. The other important characteristic of Lava Network is that it has automatic failover. Should one of the providers go offline or perform poorly, the network will automatically switch traffic to another provider. This will provide continuous service which is critical to the financial application that is 24/7. With these capabilities combined with Stellar, Lava Network makes possible production grade access. Such a high degree of reliability is essential in businesses and software developers who cannot allow downtime in the applications they are developing, like payment systems and financial settlement platforms. Enabling scalable blockchain adoption. The collaboration of Stellar and Lava Network will contribute to the rapid use of blockchain in the financial industry. The necessity to have scaled and reliable infrastructure is becoming more significant as additional institutions consider blockchain based solutions. Stellar developers now have a higher level of performance and minimized service interruption risks. This provides a more predictable platform on which innovation can occur and the team can concentrate on creating user facing capabilities as opposed to addressing infrastructure issues. In addition the integration facilitates the overall vision of decentralized finance and open financial systems. Stellar and Lava Network are helping build a more accessible and reliable global financial system by making sure that critical infrastructure is resilient. Looking ahead. The introduction of Stellar to Lava Network is an indicator of the continued development of blockchain infrastructure. The level of reliability, scalability and user experience is becoming a priority as the networks go beyond experimentation to the real world deployment. This integration makes Stellar stronger as a blockchain that can be used in financial applications and Lava Network remains to serve as a major infrastructure provider in the Web3 space.

Why Stellar (XLM) is a better choice than XRP in 2026: analyst.

Why Stellar (XLM) is a better choice than XRP in 2026: analyst. Cross-border payments continue to shape the crypto conversation in 2026, and two names keep coming up whenever that topic appears. Stellar (XLM) and XRP both promise fast and low-cost transactions, yet their direction and purpose continue to separate them in meaningful ways. A closer look shows that XRP was built mainly for financial institutions. Ripple focuses on improving how banks move large amounts of money across borders. That design works well for institutional use, but it limits how much everyday users interact with the system. The perspective shared by Sylvian Guibal, known as Stellar XLM Holder, paints a different picture for XLM. His analysis points to a model built around individuals, small businesses, and regions where access to banking remains limited. That difference becomes important as crypto adoption spreads beyond traditional finance. What you'll learn Stellar Technology Development gives XLM A broader utility advantage over XRP. Technology becomes the next major dividing line between both assets. Transaction speed and cost appear similar on the surface, yet the underlying systems move in different directions. Sylvian Guibal explains that Stellar uses a Federated Byzantine Agreement system. That model allows more open participation in validation and removes the need for central control. XRP uses a system that still ties closely to Ripple's influence, which raises questions about how decentralized it truly is. The gap becomes more visible with smart contract functionality. Stellar introduced Soroban, which expands its capabilities into decentralized finance and tokenized assets. That upgrade allows developers to build more complex applications directly on the network. Ripple continues to explore sidechains and compatibility solutions. Those efforts exist, but they do not match the level of native integration seen on Stellar. That difference gives XLM a wider range of use cases beyond simple transfers. Decentralization and regulatory history continue to shape investor confidence. Another factor that keeps coming up in this comparison involves decentralization and regulatory exposure. XRP spent years dealing with legal pressure before reaching a settlement in 2025. That episode created uncertainty that still influences how some participants view the project. Sylvian Guibal highlights that Stellar avoided similar challenges. The network operates under a non-profit structure through the Stellar Development Foundation. That setup supports a more open system without a central authority controlling large portions of supply. XRP still maintains strong connections with institutions, which brings stability in one sense but also keeps it tied to traditional financial systems. XLM moves in a direction that aligns more closely with open blockchain ideals. Market cap difference shows why XLM holds more upside potential than XRP. Market size often determines how much room an asset has to grow. Current figures place XRP between $80B and $120B in market cap, with price near $1.30. XLM sits much lower, with a valuation between $5B and $7B and price around $0.16 to $0.22. Sylvian Guibal uses this gap to explain why XLM could deliver stronger returns. Smaller market cap assets tend to move faster during strong cycles. Historical patterns show that when capital flows into altcoins, lower-cap projects often expand more aggressively. That does not guarantee performance, yet it explains why attention continues to build around XLM when market conditions improve. Real world usage shows Stellar adoption growing in emerging markets. Adoption on the ground tells another important story. XRP continues to build partnerships with financial institutions, although many of those developments take time before they translate into daily usage. Stellar moves differently. Its network already supports remittances and microtransactions in regions across Africa, Latin America, and Southeast Asia. That activity connects directly to people who need low-cost financial access. Sylvian Guibal points to this usage as a key strength. The ecosystem supports stablecoins, tokenized assets, and payment rails designed for everyday use. That creates an environment where growth comes from real interaction, not only institutional agreements. The comparison between XLM and XRP ultimately comes down to direction. XRP continues to serve traditional finance as it evolves. Stellar builds toward a system that focuses on accessibility and open participation. Sylvian Guibal maintains that this difference defines the long-term outlook. XLM expands beyond payments into a broader financial infrastructure. XRP remains effective for institutional transfers, yet its role stays more limited in scope.

Finexity AG: Cashlink, FINEXITY and Tangany Launch Regulated Tokenized Capital Market Infrastructure on the Stellar Blockchain.

Finexity AG: Cashlink, FINEXITY and Tangany Launch Regulated Tokenized Capital Market Infrastructure on the Stellar Blockchain. Finexity AG/ Key word(s): Alliance/Miscellaneous Finexity AG: Cashlink, FINEXITY and Tangany Launch Regulated Tokenized Capital Market Infrastructure on the Stellar Blockchain 02.04.2026 / 11:33 CET/CEST The issuer is solely responsible for the content of this announcement. Cashlink Technologies GmbH, FINEXITY Group, and Tangany have jointly implemented an infrastructure project supported by the Stellar Development Foundation. The project's objective is to build and productively deploy a regulated, interoperable, token-based capital market infrastructure on the Stellar blockchain. The infrastructure developed as part of the project has already been deployed in a first real-world use case: the tokenized securities issuance for the Ratekau Solar Park in Germany is executed - technically and from a regulatory standpoint - via the shared infrastructure. The issuance volume amounts to up to EUR 3.0 million. This use case serves to validate the end-to-end setup under live market conditions. The project is realized under a grant from the Stellar Development Foundation, which specifically supports practice-oriented applications to further adoption and maturity of the Stellar ecosystem in institutional contexts Building a Productive Value Chain on Stellar The project covers the complete lifecycle of tokenized securities and integrates regulatory record-keeping, institutional custody, and issuance and settlement within a single, unified setup on the Stellar blockchain. Cashlink, as a BaFin-licensed crypto securities registrar, fulfills the core regulatory function and provides the technical and legal foundations for registry maintenance and issuance. Tangany complements the infrastructure with institutional custody solutions for the secure and regulatory-compliant safekeeping of tokenized assets. FINEXITY is responsible for the capital market-grade structuring and execution of the project in the form of a live issuance, contributing its distribution capabilities and settlement expertise to the shared infrastructure. The open architecture enables additional market participants to connect to the infrastructure, thereby contributing to a reduction of fragmentation in the DLT-based capital markets. The Stellar network is one of the leading blockchains for the tokenization of regulated financial products. Tokenized assets with a total volume of over USD 1.6 billion are currently represented on the network, including from institutional issuers such as Franklin Templeton, WisdomTree, and Spiko. With this issuance via FINEXITY, the Stellar ecosystem gains its first tokenized infrastructure bond from the regulated German capital market. Live Use Case on the Stellar Blockchain The infrastructure built as part of the project is already in productive use: via the FINEXITY platform, the tokenized bond for the Ratekau Solar Park of Green Vision Two is being issued. The project encompasses an open-field solar park in northern Germany with an issuance volume of up to EUR 3.0 million and total investment of approximately EUR 5.7 to 5.8 million, including bank financing. The solar park combines a photovoltaic system with 4.13 MWp installed capacity and an expected annual output of approximately 4.27 GWh with an integrated battery energy storage system (BESS) of the CATL TenerStack type, which can be charged flexibly from renewable generation or the grid. This extends the revenue logic beyond pure power generation and serves as an example of structured financing for real-world infrastructure projects via tokenized capital market instruments. "The Solarpark Ratekau bond issuance demonstrates how tokenized capital markets work in practice: institutional-grade, efficient, and accessible to investors starting at €50. The fact that three licensed German partners - Cashlink, FINEXITY, and Tangany - are now productively using the Stellar blockchain highlights the growing role of the Stellar network in European capital markets." - Malte Baumann, Director of Tokenization & RWA, Stellar Development Foundation Disclaimer This announcement does not constitute a public offering or a solicitation of a public offering of securities, particularly within the meaning of Regulation (EU) 2017/1129 (Prospectus Regulation).

Stellar picks Zebec to power global stablecoin payroll across its ecosystem.

Stellar picks Zebec to power global stablecoin payroll across its ecosystem. * Guido Battigelli * Published: March 19, 2026 * 7:25 pm * Updated: March 19, 2026 * 7:25 pm Home > flash news > Stellar picks Zebec to power global stablecoin payroll across its ecosystem. Table of Contents Zebec announced its native integration on the Stellar network, marking the first deployment of its payment streaming infrastructure outside the Solana blockchain. The selection was made by the Stellar Development Foundation itself, which identified it as the ideal protocol to bring real-time payroll to its ecosystem. The integration allows companies to pay salaries per second, continuously, in USDC directly on Stellar. Instead of waiting business days for funds to become available, workers can access their earnings the moment they are generated, and spend or withdraw them via cards or local remittance networks. The deployment will take place in phases, beginning with core payroll functionality and expanding toward global payment rails with fiat integrations. A key component of the system is Stellar's connection with MoneyGram, which enables the conversion of digital dollars into local cash at more than 450,000 withdrawal points distributed across more than 170 countries. That means a worker paid in USDC can receive funds instantly while their family withdraws cash in minutes from Manila to Mexico City. Zebec has been collaborating with Stellar for over two years on card infrastructure, which made this integration an organic step toward full native functionality within the ecosystem.
