Watch + listen

OpenZeppelin developer Steve Sinkens demonstrates monitors and relayers, open-source backend services for Stellar smart contracts. Monitors watch contracts and trigger notifications; relayers execute transactions on-chain based on custom rules. Both tools are essential for Meridian hackathon participants building on Soroban.

Developer explores building verifiable, unhackable games using zero-knowledge proofs on Stellar, focusing on a Pong game integrated with Blend protocol's fee vault to distribute yield to game winners.

Developer builds a decentralized chat web app using Soroban smart contracts and speech-to-text API. The 13-line contract stores messages as on-chain events, eliminating need for traditional servers or databases.

Protocol 23 launches September 3rd, enabling parallel transaction processing on Stellar mainnet. Soroban smart contracts gain faster memory access and lower execution costs, while unified events improve wallet and explorer compatibility.

Stellar launches Audit Bank, a community initiative providing developers with subsidized security audits from leading firms. Projects pay only 5% upfront, refundable if critical bugs are fixed within 20 days, with follow-up audits free after reaching $10M-$100M TVL milestones.

Tomer Weller, CPO of Stellar, discusses the implementation of smart contracts via Soroban, the network's consensus mechanism, and upcoming innovations including scalability improvements and privacy solutions to support institutional adoption.

Stellar Foundation and Veridice discuss the Stellar Security Audit Bank, a program providing free security audits to Soroban developers. The initiative aims to make security proactive rather than reactive, with audits funded through the Stellar Community Fund for qualifying DeFi protocols.

Tutorial on building a Soroban smart contract implementing a call option using XLM and USDC tokens. Covers option mechanics, contract code structure, unit testing with time simulation, and deployment to testnet.

Tutorial on writing and deploying your first Soroban smart contract in Rust, from Hello World to a practical hit counter example with web integration and three key developer tips.

Two developers live-code a fungible token and NFT contract on Soroban using the Soroban Playground, a new web-based IDE for smart contract development. They deploy working contracts to testnet and explore the contract explorer interface.

Developer builds a binary prediction market smart contract on Stellar's Soroban platform, demonstrating how to create true/false outcome betting using open-source code with token transfers, oracle integration, and individual claim functions.

OpenZeppelin released a new NFT royalties extension for Stellar's Soroban smart contracts, enabling developers to set up and earn royalties on NFT collections. The tutorial demonstrates how to deploy and configure the royalty contract on testnet.

Vivo from Ahlabs demonstrates Scaffold Stellar, a comprehensive developer framework for building on Stellar and Soroban. The tool includes CLI plugins, contract templates, local deployment, TypeScript client generation, and an integrated contract explorer frontend.

Scaffold Stellar by AHA Labs is a Rust-based development framework that provides a complete boilerplate for building Soroban smart contracts with pre-integrated frontend wallet support, enabling developers to initialize projects, deploy contracts, and iterate in real-time.

Tutorial on building a custom stablecoin on Soroban using OpenZeppelin contracts. The creator demonstrates how to create a SEP41 token called JUSD that accepts USDC deposits and mints a corresponding stablecoin in a 1:1 ratio, using a new online IDE.

Sertora presents Sunbeam, a formal verification tool for Soroban smart contracts that uses SMT solvers to mathematically prove code correctness against specifications written in Rust, enabling developers to catch bugs early in the development cycle.

Developer migrates a Solidity perpetual futures contract to Soroban using AI tools, walking through the differences between EVM and Rust/WebAssembly development, contract simplification, and debugging with unit tests.

Tutorial on using OpenZeppelin's Monitor software to track USDC transfers on the Stellar network and send real-time notifications to Telegram. Covers setup, configuration, contract interaction, and bot integration.

Tutorial on creating and deploying an NFT smart contract on Stellar's Soroban network using OpenZeppelin libraries, including contract modifications, metadata creation, and testnet deployment.

A technical walkthrough of a Soroban smart contract written in Rust, explaining imports, macros, data structures, storage patterns, and the require_auth security function for on-chain message storage.

Jane from SDF and Chad from Aha Labs discuss Scaffold Stellar, a developer onboarding tool inspired by Scaffold ETH. Aha Labs is building it to help developers quickly set up local networks, deploy contracts, and create UIs, with an early version available by end of May 2025.

Stellar developers discuss launching an idea bank to help builders discover needed projects and coordinate ecosystem development. The initiative aims to guide hackathon participants and identify gaps in the Stellar and Soroban ecosystem.

Developer tutorial demonstrating how to build a web-based wallet using the Stellar SDK and integrate it with Blend Capital smart contracts to enable users to deposit funds and earn yield on their holdings.

Esteban from Palta Labs discusses SorosWap's DeFi Index product, wallet integrations, and crypto adoption across South America, highlighting Brazil's advanced fintech infrastructure and the potential for blockchain-based financial services.
