Stellar's blockchain platform has been a game-changer in quick and affordable cross-border transactions, while's reliable API offerings for diverse DApps have positioned us as a key player across multiple blockchains. Together, we are poised to inspire a dynamic shift in the realms of blockchain and global finance.

What is Stellar

Stellar is an open-source, decentralized blockchain network designed to facilitate swift, low-cost cross-border transactions. Introduced in 2014 by Jed McCaleb, co-founder of Ripple and eDonkey, the Stellar network operates on a unique consensus protocol rather than the traditional proof-of-work or proof-of-stake mechanisms. People use Stellar network to build applications, issue assets, and build anchors (currency converters).

Stellar Soroban

Soroban is a smart contract platform that is integrated into the existing Stellar blockchain. Developers could develop smart contracts with a Rust dialect and interact with Stellar’s accounts and assets, not other operations like SDEX, AMMs, Claimable Balances, or Sponsorships.

The Soroban mainnet upgrade is scheduled for February 20th .

What is is an API marketplace powering DApps of all sizes for Sui, Aptos, Solana, and 12 EVM blockchains. Why do our customers choose us?

  1. High availability. We maintain 99.9% uptime since our first API - Aptos main net launch.
  2. Inclusive API offerings and community. Our services have expanded to include Sui, Ethereum, IoTeX, Solana, Polygon, Polygon zkEVM, Filecoin, Harmony, BSC, Arbitrum, Optimism, Gnosis, Arbitrum Nova & EthStorage Galileo. Our community has 4000+ web3 innovators from Silicon Valley, Seattle, and NYC.
  3. Security. With over $45 million worth of tokens staked with us, our clients trust us to provide reliable and secure solutions for their web3 and blockchain needs.

We provide a comprehensive suite of services designed to empower every participant in the blockchain space, focusing on three key areas:

  • For blockchain protocol builders, we ensure robust security and decentralization by operating nodes and making long-term ecosystem contributions.
  • For DApp developers, we build user-friendly APIs to streamline development and unleash the full potential of decentralized applications.
  • For token holders, we offer a reliable staking service to maximize rewards and optimize asset management.

What is building on Stellar and what does this mean for developers? is leveraging the Stellar network to offer commercial Soroban RPC and indexed data to help DApp developers to speed up development with a GraphQL API and analytics.

This comprehensive expansion into Stellar's infrastructure is set to present developers with more resources and tools, potentially facilitating easier adoption and more robust application development within the Stellar blockchain ecosystem.

Node operator and Indexer for Soroban RPC and Indexer GraphQL

As a node operator, runs Soroban RPC, and then provides commercial standard RPCs to developers on the left. Unlike the official endpoints, our RPCs are equipped with rate limits and API meters tailored to developers’ tiered needs. also builds an indexer for contract data, tokens, events, etc. in the Soroban smart contract platform.

The index data will serve as GraphQL. The exact content of the index data is to be decided, though we will expose at least the developer-facing data models of the Horizon service.

Business Intelligence / Analytics

Soroban RPC

For developer's convenience, we also serve the standard JSON RPC.


In conclusion, as we pave the way towards a new era in blockchain and global finance, our partnership with Stellar represents a significant milestone. Harnessing Stellar's swift, cost-effective transaction capabilities and's high-quality API offerings, we are poised to create a paradigm shift in the way developers engage with the open money network. We hope this work will inspire innovations, trigger advancements, and propel us all towards a more connected and decentralized world.

As the CEO of a startup in the web3 domain, I'm often intrigued by emerging tech trends. The rapid ascent of bot platforms, particularly in the context of blockchain and decentralized finance, has caught my attention.

The New Wave: Telegram Bots in Web3

With the growth of Unibot, robot concepts are becoming a new area of competition. The landscape now features hundreds of bot-centric and micro-innovative projects. Telegram, a must-have social application in the crypto circle, boasts a staggering 800 million monthly active users. These numbers become even more fascinating when you consider how Telegram Bots are simplifying crypto interactions. Within the platform, bots can handle a variety of tasks, from decentralized finance (DeFi) and miner extractable value (MEV) protection to data analytics, whale tracking, and even community gaming governance. The appeal lies in their accessibility, convenience, and wide-ranging applications.

However, rapid growth often brings skepticism and worries. Concerns about the security vulnerabilities of Telegram Bots and the maturity of the technology have begun to surface.

The Rise of Web3 Bots: Analyzing Unibot and Its Contenders

Unibot: The Phenomenon

Launched in June, Unibot took just two months to achieve a phenomenal status, spawning hundreds of imitative projects. It hit a peak market cap of over $200 million, although it later faced stiff competition from "Banana Gun", leading to a considerable market share decline. Despite this drop, its current market value stands around $60 million, keeping Unibot as the leading figure in the bot arena.

Unibot Features:

  • New project tracking
  • Copy-trading capabilities
  • Limit orders
  • Token tracking and precision sniping within Telegram
  • Speedier than conventional decentralized exchanges, outpacing platforms like Uniswap.

Revenue Model:

  1. Service Fee: Unibot charges a 1% service fee. 40% of this is allocated to $UNIBOT Token holders, with the remaining going toward team operations.
  2. $UNIBOT Token Tax: The token imposes a 5% tax. 1% of the transaction volume is shared with $UNIBOT holders.

In its prime, daily revenue reached beyond 300 ETH. Despite challenging market conditions, Unibot has performed impressively, garnering approximately 15,000 users and generating around 8,200 ETH (approx. $13 million) in total revenue within three months.

Banana Gun: The Challenger

Banana Gun, a recent entrant, has managed to challenge Unibot's dominance. With features similar to Unibot, it has garnered a user base comparable in size, but with slightly more active members. Notably, it's proving to be more effective in its "sniping" capabilities. Banana Gun's recent pre-sale raised 800 ETH, and they faced some liquidity withdrawal issues due to contract tax complications.

The Broader Bot Ecosystem

Other bots in the market focus on various niche aspects, such as:

  • Analyzing contract details for potential red flags, like liquidity pool locks, contract access renunciations, and "rug pull" possibilities.
  • Tracking the actions of high-performing wallet addresses.
  • Monitoring newly launched project tokens for potential early investment opportunities.

Why Are Bots Gaining Traction?

  1. Their integration with Telegram, one of the most widely-used applications in the industry, provides a natural congregation of traffic.
  2. The essence of buying and selling remains a fundamental need in finance. The functionalities of these bots revolve around trading, and ultimately, profitability is their selling point.

In conclusion, the world of web3 bots is evolving rapidly. As decentralized technologies mature, bots will undoubtedly play a significant role in the way we interact with and leverage the capabilities of the blockchain. As a stakeholder in this space, I'm excited to be a part of this journey and look forward to the innovations that lie ahead.

  2. For improved granularity, 1 CU has been updated to 100 CU.
  3. Announcing our new "Basic" plan priced at $19.99.
  4. CUs are now denominated in CUC and are refreshed daily. Monitor your balance at
  5. With our updated plans, extra CUCs beyond those plans allow you to access extra API calls using a pay-as-you-go system every day. is committed to providing cost-effective and efficient solutions to DeFi, wallet, and analytics developers. Our customer feedback revealed a few key insights:

  1. A requirement for an intermediate tier between the Free and Pro plans.
  2. A desire for a more flexible 'pay-as-you-go' option.
  3. An opportunity for us to accommodate more requests through a more efficient infrastructure.

Based on these insights, we're excited to announce the introduction of a pay-as-you-go feature using Compute Unit Credit (CUC), and to share details about modifications to our pricing plans.

Understanding Compute Units and Compute Unit Credit

A Compute Unit (CU) serves as a standard measurement that quantifies the computational expense incurred during an API call. It's akin to how AWS charges for compute usage. The computational cost varies depending on the intensity of the queries – some are lightweight and fast (e.g., eth_blockNumber) while others can be more demanding (e.g., large eth_getLogs queries). The cost in CU for each request across different products can be found in our API marketplace.

Compute Unit Credits (CUC) are like credit card rewards on our platform to serve as royalty points. Those points are identical to compute units. Developers could spend CUC on our platform to get extra quotas for API calls.

Implementing Pay-As-You-Go with CUC

We'll set up a reward account for each customer. Customers can load this account with CUC, which will then be consumed as per their API usage.

  • For the Free tier, we ensure a minimum balance of 0.3 CUC at the start of each month.
  • For the paid tiers (Basic, Pro, Enterprise 50), we will credit the account on each subscription or renewal.

We do not allow customer to withdraw CUC for now.

The credits on will be reconciled daily and also each time a withdrawal or deposit is made. maintains the rights to the Compute Units (CU) on our platform, along with the authority to clarify the application of the API and the usage of credits.

Pricing Plan Modifications

Below are the changes to our pricing plans. The original pricing structure was as follows:

In the evolving landscape of Web3, a new approach to user interactions is emerging – the intent-centric protocol. Here, users simply express what they want, leaving the intricate process of how it's achieved to the system. This approach heralds enhanced user experience, better composability, and greater privacy.

The Three Pillars of Intent-Centricity

  1. User-Centric Interaction: The essence of intent-centricity lies in streamlining user experience. By emphasizing the "what" over the "how," it spares users the need to grapple with complex underlying mechanisms. The result? A straightforward expression of their objectives.

  2. Robust Composability: In the realm of Web3, composability denotes the ease with which various protocols or apps integrate and build upon each other. When users solely voice their intent, it provides room for systems to be tailored for maximized compatibility, fostering richer and more cohesive digital ecosystems.

  3. Privacy by Design: Expressing just the intent can obviate the need for users to disclose detailed or sensitive data about themselves. This is a major stride towards ensuring user privacy in blockchain interactions.

Let's Paint a Picture

Consider Alice – a newcomer to the DeFi (Decentralized Finance) world with minimal technical expertise. She's just dipped her toes into the realm of cryptocurrency and is curious about staking to earn interest.

Traditional ProtocolIntent-Centric Protocol
1. Alice starts by selecting a staking platform.
2. She grapples with its intricacies.
3. She's faced with choices: locked staking or flexible?
4. Next, she must comprehend the risks linked to her choice.
5. Finally, after a labyrinthine process, she stakes her cryptocurrency.
1. Alice accesses a Web3 app.
2. She straightforwardly states: "I wish to stake X crypto and earn interest."
3. The protocol, cognizant of her intent, optimizes the staking method for her – considering market dynamics, her stake, and more.
4. Behind the scenes, it liaises with the required DeFi protocols, managing the technicalities.
5. Alice gets an affirmation: her cryptocurrency is staked and interest earnings are on the way.

For Alice, the intent-centric approach is a breath of fresh air. She’s spared the technical maze and instead, expresses her intent. The protocol does the heavy lifting, ensuring her privacy and sourcing the best available options.

What Fuels the Rise of Intent-Centricity?

The rising wave of intent-centricity is spurred by a blend of the AIGC revolution, developments like EIP4337 (smart contract accounts), and the push to make Web3 accessible to all.

A testament to this trend is the project showcased at ETHGlobal Paris 2023: Bob the Solver - Pioneering infrastructure for intent-based transactions to elevate the UX of wallets and dapps.
