A tutorial demonstrating how to build a Soroban smart contract that automates savings by fetching real-time XLM prices from Reflector Oracles and triggering conversions when price thresholds are met.
George Kudrayvtsev demonstrates how the Composable Data Platform (CDP) and Galexie enable efficient backfilling of Stellar RPC with historical ledger data in just 12 minutes—a task that would take over an hour using traditional captive core replay. The prototype required only 80 lines of Go code and showcases CDP's flexibility for building composable ingestion pipelines.
Runtime Verification details their process for building formal verification and fuzzing tools using the K Framework to enhance smart contract security. They highlight tools like Kontrol for Ethereum and Komet specifically for Soroban smart contracts on Stellar. The post aims to bridge the gap between developers and advanced security tooling.
This article explores how passkeys—a secure, user-friendly authentication method already adopted in Web2—are being integrated into Stellar's blockchain to improve user experience and drive adoption. Stellar gained a significant advantage by implementing native secp256r1 support in Protocol 21, enabling passkey functionality directly at the protocol level rather than through third-party solutions.
Tansu is launching a DAO system that enables communities to govern their projects in a decentralized fashion. All projects created on Tansu will receive their own DAO with transparent, immutable governance through smart contracts and IPFS-stored proposals.
Stellar launches Build Better, a community-driven initiative that collects ideas from the ecosystem across three focus areas (finance, creativity, access) and translates them into hackathon tracks. The program offers a $30K prize pool and aims to bridge Web3 vision with real-world implementation using Stellar's smart contract platform.
Stellar-core 22.1 will drop SQL support for ledger state and transaction history tables. The release introduces a new high-throughput HTTP query server with the `getledgerentryraw` endpoint as the replacement for direct SQL access.
A detailed recap of Meridian 2024's Dev Underground stage in London, where 80+ Stellar Community Fund winners pitched their projects over two days in a casual, collaborative environment. The article highlights standout projects, community collaborations, and the vibrant energy of builders across the Stellar ecosystem.
The Stellar Development Foundation has achieved a 9x speedup in Horizon reingestion by leveraging the Composable Data Platform (CDP) with precomputed ledger metadata, reducing full history reingestion from approximately 66 days to 7 days.
Protocol 22 is now live on Stellar Mainnet. This guide provides developers and businesses with upgrade instructions, key dates, release links for all Stellar infrastructure and SDKs, and important changes including the Soroban RPC rebrand to Stellar RPC and upcoming Horizon transaction meta defaults changes.
SorobanDomains introduces a new Key-Value storage contract on Stellar's Soroban platform, acting as a 'localstorage' for domains. It enables storing additional values like SEP-01 TOML file locations or IPFS CIDs for dApps. The contract is live on mainnet with a $PSD 100 registration fee.
zkCross Network announces Super Accounts on Stellar, powered by their Chain Abstraction Layer, enabling seamless 1-click cross-chain DeFi transactions without bridging or gas management. This integrates zkCrossDEX with Stellar's Soroban blockchain, supported by a Stellar Community Fund grant. The phased roadmap includes AMM DEX, staking, launchpad, and perpetuals trading.
Hubble's Stellar ETL has been refactored to use the Composable Data Platform (CDP), replacing Captive Core with Galexie and a Ledger Metadata Store. This architectural change delivers 93% faster processing, 90% cost reduction, and significantly simplified maintenance.
Tansu integrates stellar.expert's contract validation mechanism to ensure its on-chain contract matches the source code repository. This uses GitHub actions and SLSA attestations for supply-chain security. The feature verifies contract provenance on the Stellar blockchain explorer.
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.
The Stellar Development Foundation has launched an all-new Stellar Lab, a modernized web-based toolkit for developers to create accounts, test transactions, explore RPC methods and Horizon endpoints, and interact with the Stellar network. The redesigned interface includes mobile optimization, XDR-to-JSON conversion support, and the ability to save and share API requests.
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.
Mercury has released Retroshades, a smart contract indexing technology designed specifically for Soroban-supporting chains. Retroshades allows developers to build custom indexers in minutes by defining data structures directly within smart contracts, eliminating the need to learn new technologies or manage complex infrastructure.
Tansu project announces submission for SCF Build award, outlining plans for a decentralized platform with DAOs for project management and reputation badges for contributors. The proposal includes on-chain release processes, fund allocation via wallets and potential Quadratic Funding, and a detailed roadmap across MVP, Testnet, and Mainnet phases. Emphasis is placed on community governance, transparency, and open-source sustainability within the Stellar ecosystem.
Runtime Verification introduces Komet, a formal verification and fuzzing tool for Soroban smart contracts on the Stellar blockchain, funded by the Stellar Community Fund. The tool aims to enhance smart contract security through mathematical guarantees against vulnerabilities. The team seeks continued community support to expand its capabilities.
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.
