Soroswap, the first DEX on Stellar blockchain, evolved into an AMM aggregator to combat fragmented liquidity. They partnered with PaltaLabs for development and Runtime Verification for auditing via the Stellar Audit Bank program. The audit enhanced security and provided key insights like using deployer contracts.

Tansu, a Stellar dApp, introduces an on-chain 'Support' button for funding open source projects directly via Soroban Domains. This creates transparent, costless, and borderless funding using Stellar addresses and smart contracts. Future developments include DAO-based fund management through the SCF Build program.

Komet is a new tool from Runtime Verification for property testing and formal verification of Soroban smart contracts on the Stellar blockchain. It supports fuzzing and symbolic execution, integrating seamlessly with Rust for enhanced contract security. The article provides installation steps and a detailed case study testing a simple 'adder' contract.

Tansu, a Soroban-based versioning dApp, launches v1 on Stellar testnet, allowing project registration and on-chain Git history tracking. It completes SCF28 activation award deliverables, including smart contracts with Soroban Domains support and open-source tooling. The team thanks the Stellar community and eyes a Build award next.

This article explores the evolution of wallets from ancient times to modern smart contract wallets, highlighting how Stellar's infrastructure enables user-friendly, secure smart wallets with features like gasless transactions, passkey authentication, and account abstraction.

Technical comparison of three smart contract languages from someone who's shipped on all three. Solidity dominates by ecosystem size but carries well-known vulnerability classes. Soroban brings Rust's memory safety to Stellar with built-in resource metering. Plutus offers formal verification through functional programming but demands significant learning. Practical analysis of trade-offs for enterprise projects.

The Build Better on Stellar Smart Contract Challenge concluded with winners across tutorial and dApp categories, featuring projects like Entry•X (decentralized ticketing), DVILLA (sustainable e-commerce), and Soroban by Example. Winners received up to $13,000 USD and invitations to Meridian 2024, with next steps including SCF Kickstart and the Stellar Community Fund.

The Stellar Development Foundation and DEV announced the winners of the Build Better on Stellar: Smart Contract Challenge, with over $50,000 in prizes distributed across tutorial and dApp categories. Winners included projects like Soroban by Example, Entry X (decentralized ticketing), and DVILLA (sustainable e-commerce), with overall winners receiving $13,000 and all-expenses-paid trips to Meridian conference.

This article explains smart contract wallets (smart wallets) and their advantages over traditional crypto wallets, including enhanced functionality, security features, and passkey support. It highlights how Stellar's Protocol 20 and 21 enable passkey-powered smart wallets to improve user onboarding and accessibility.

This article explains token vesting and streaming protocols, highlighting their importance for crypto projects to align incentives and prevent dumps. It details closed-ended and open-ended streaming models, with examples like Sablier, Superfluid, Hedgey, and LlamaPay. TokenOps is presented as a platform integrating these for efficient vesting management.

Tansu deployed its Soroban smart contract to testnet with event handling infrastructure now live. The governance platform released a Python library on PyPI. Upcoming milestones: dApp proof-of-concept, FastAPI backend, and continuous contract deployment.

Coinspect has published the results of their security audit of the Tricorn Bridge's Soroban integration, conducted in collaboration with Boosty Labs and the Stellar Development Foundation. The audit identified 3 high-risk, 6 medium-risk, and 1 low-risk vulnerabilities in the smart contract's Rust source code and Golang backend. All findings have been addressed by the development teams, enhancing Soroban security knowledge.

Rob Durst announces Digicus, a visual block-based IDE for Soroban smart contract development that aims to lower the barrier to entry for developers. The tool allows developers to visualize, understand, and edit Soroban contracts without requiring deep Rust expertise.

Stellar introduces State Archival, a protocol solution to blockchain state bloat that archives unused ledger entries while maintaining security through Merkle proofs stored in History Archives. This approach enables Stellar to maintain low validator costs, high throughput, and scalability without requiring expensive hardware.

This article compares Stellar's State Archival solution with Solana's State Compression (Avocado), arguing that Stellar's approach is more efficient and scalable. The analysis highlights fundamental flaws in Solana's design including poor data availability guarantees, increased network congestion, and higher costs.

The Stellar Development Foundation and DEV Community are launching the Build Better on Stellar: Smart Contract Challenge, running through August 18, offering a $50,000 prize pool and free trip to Meridian Conference for developers building dApps with Soroban smart contracts.

Stellar's newly launched Soroban smart contracts platform addresses key Web3 pain points including liquidity fragmentation, high transaction costs, and accessibility. With 80,000+ USDC on-ramps globally, an established user base of 8.4 million accounts, and a $100 million SDF commitment to builders, Stellar offers a mature, scalable foundation for DeFi development.

Stellar Protocol 21 went live on June 18, 2024, introducing five Core Advancement Proposals including native secp256r1 verification for passkey support in smart contracts, alongside efficiency improvements for state archival and transaction costs.

Stellar's Protocol 21 upgrade activated on June 18, 2024, introducing five Core Advancement Proposals (CAPs) that enable passkey support for smart contracts, improve state archival, and reduce transaction costs through VM optimization and module caching.

Stellar launched Soroban, a smart contract platform integrated into Protocol 20, addressing key blockchain challenges like transaction speed, security vulnerabilities, state bloat, and high costs while leveraging Stellar's extensive payment rail network for real-world DeFi applications.

Stellar launches Soroban smart contracts platform, enabling a new DeFi ecosystem on the network. Built with Rust and WebAssembly for developer familiarity, Soroban maintains Stellar's focus on low costs, scalability, and financial inclusion while protocols like Soroswap and XycLoans already deploy on mainnet.

FxDAO shares its Q1 2024 update, highlighting the completion of a smart contract audit by Runtime Verification and adaptations to Soroban platform changes on Stellar. Despite challenges like limit downgrades requiring refactors, the team resolved issues to fit current network limits. They are preparing for mainnet launch with vaults for synthetic USD, EUR, and GBP, alongside plans for a custom oracle.

Stellar Protocol 21 activated on Mainnet on June 18, 2024, introducing five Core Advancement Proposals (CAPs) that add passkey signing support, improve state archival, and reduce smart contract transaction costs. Developers and operators must upgrade their Stellar-related software and re-upload existing Wasms to benefit from the new cost model.
