This article explains the importance of swap functionality and Automated Market Makers (AMMs) for financial inclusion, detailing how AMMs work, their advantages, and challenges like impermanent loss. It highlights how Soroban smart contracts on Stellar enable developers to build sophisticated AMM protocols for trustless, incentivized liquidity provision.
AssetDesk has secured an R&D grant from the Stellar Community Fund to develop the AssetDesk protocol, a new money markets protocol for Stellar's Soroban smart contracts platform. The protocol enables decentralized borrowing and lending with features like margin trading, flash loans, NFT lending, and stablecoin markets. It aims to enhance capital efficiency in Stellar's DeFi ecosystem.
RPCiege Siege 4 launches with three new Soroban Rust coding challenges (Skirmish 8-10) designed to teach smart contract development while gamifying the learning experience with a fantasy narrative.
The Stellar Newsletter highlights key developments including the launch of the open-source Stellar Disbursement Platform, Allbridge's cross-chain bridge connecting Stellar to Ethereum, Solana, Celo, and Polygon, and SDF's investment in MoneyGram International. It also promotes Meridian 2023 conference, developer tools for Soroban, and various ecosystem updates like Airtm's USDC integration and Q2 review. The content emphasizes Stellar's growth in interoperability, financial inclusion, and smart contract scalability.
Soroban has achieved feature completeness after a year of public development through 10 preview releases, with over 70 ecosystem projects now building in parallel. The platform is closing in on a stable release candidate with a renewed focus on developer experience, tooling, and documentation.
Soroban's fee structure uses granular resource metering to price compute, memory, and storage independently, enabling more efficient block utilization and lower validator costs than traditional gas-based systems like Ethereum's.
The Stellar Development Foundation outlines seven current and upcoming developer programs for Soroban, ranging from content bounties and hackathons to educational challenges and coding puzzles, with awards up to $150,000 XLM for builders creating end-to-end products.
This article outlines the essential building blocks required for a thriving smart contract ecosystem on Soroban, including financial protocols (AMMs, lending markets), data access tools (oracles, indexers), user interfaces (wallets, block explorers), and security mechanisms. It demonstrates how these interconnected components enable real-world DeFi use cases like decentralized lending.
Fonbnk is a fintech platform that enables financial inclusion in emerging markets by converting prepaid mobile airtime into USDC on the Stellar network, providing seamless on and off-ramps for cash-based economies across Sub-Saharan Africa.
MoneyGram International has launched MoneyGram Ramps, a cash-to-crypto on and off-ramp service powered by the Stellar blockchain and USDC stablecoin. The service enables unbanked and underbanked populations to convert physical cash to digital assets at MoneyGram's 480,000+ locations worldwide, addressing the critical last-mile problem in blockchain adoption.
Arf, a regulated liquidity and settlement platform, leverages the Stellar network and USDC to provide cross-border payment solutions for financial institutions. By eliminating pre-funding requirements and enabling same-day settlements, Arf has extended over $830 million in loans with $1.6 billion in on-chain transaction volume since 2022.
Vesseo is a wallet app built on Stellar by Sunship, Inc. (an SDF subsidiary) that enables Argentines to quickly and cheaply purchase and hold USDC to protect against peso devaluation. The app leverages Stellar's fast settlement, low fees, and asset issuance capabilities to provide a simple alternative to traditional dollar-holding methods.
A comprehensive guide to Rust development for smart contracts on Soroban, covering setup, language advantages over Solidity, and resources from the Stellar Development Foundation for learning and building.
RPCiege is a series of Soroban smart contract coding puzzles that teach Rust fundamentals through gamified challenges. Players complete skirmishes to earn digital collectible cards, with eight challenges released so far covering contract invocation, string types, testing, RPC queries, callbacks, RNG, and byte array operations.
This article explores the various consensus mechanisms available in Hyperledger Fabric, including PBFT, Kafka, Raft, Solo, and IBFT. It details their characteristics, use cases, and how they integrate with Fabric's architecture like ordering services and endorsement policies. A brief mention of Stellar Consensus Protocol (SCP) appears in the context of external consensus integration.
Soroban implements state expiration to address blockchain state bloat, becoming the first blockchain to deploy this solution at mainnet launch. The design includes an Expired State Store, two storage types (Temporary and Persistent), and a rent model to prioritize important data and improve network scalability.
The Stellar Development Foundation launched Hubble, a BigQuery-based analytics dataset offering complete historical records of the Stellar blockchain. Hubble enables complex data analysis without maintaining full history databases, supporting large-scale computing and historical applications previously difficult to implement.
The Stellar Newsletter highlights upcoming events like Meridian 2023 in Madrid with Idris Elba, MoneyGram's USDC case study on Stellar, and Coinbase's integration with USDC on the network. It covers improvements to the Anchor Directory, wallet on/off-ramp integrations, Soroban infrastructure projects, and a new Soroban security bug bounty. Developer updates include proposed transaction changes and SCF submission best practices.
Soroban Preview 10 introduces new State Expiration logic to address blockchain bloat issues, along with Rust SDK changes and clearer smart contract limits. July focused on refactors rather than new features, including rethinking governance token distribution. A new Stable Liquidity Pools contract for stablecoins is in development for future deployment.
