Mule Fahreau discusses formal verification best practices for Soroban smart contracts, covering code modularity, AI-assisted refactoring, and combining AI with formal verification tools to improve security and auditability.

Marta from Stellar Core team discusses 2025 scalability achievements, including background transaction processing, parallel Soroban execution, and theoretical throughput nearly doubling to over 2400 TPS. The team is experimenting with consensus-execution pipelining to further increase throughput while maintaining latency.

NetherMind's ZK engineering team presented a privacy solution for Stellar using zero-knowledge proofs and privacy pools with regulatory compliance, addressing the blockchain's transparency-by-design limitation while enabling opt-in privacy for users.

Chad Oh from The Aha Company presents Scaffold Stellar, a rapid application development tool for building Stellar dApps with smart defaults and minimal setup. The talk covers the Stellar Scaffold CLI for project initialization and the Stellar Registry for publishing and managing WASM binaries on-chain.

Stellar Development Foundation research team discusses performance and scalability improvements including JIT execution for Soroban contracts, parallel processing strategies, network overlay optimization, and consensus protocol enhancements targeting sub-second latency.

Numix presented the Diamond Proxy Standard for Soroban, enabling upgradable smart contracts with shared storage. This allows asset managers to deploy on-chain without immutability constraints, addressing regulatory compliance needs for real-world asset tokenization on Stellar.

Protocol enhancement proposals for Stellar's Soroban smart contracts: CAP 71 introduces delegated authentication to simplify multi-signer logic, CAP 72 adds contract signers to classic accounts, and CAP 73 enables trust line creation from Soroban.

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.

Esteban Iglesias from Paltolabs presents SourceSwap and DeFindex, two major DeFi protocols on Stellar. SourceSwap is a DEX aggregator that routes trades across multiple liquidity sources via smart contracts and APIs, while DeFindex enables wallets and fintech apps to offer yield-generating savings accounts through automated DeFi strategies.

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.

Enzo and Fifro from Aha Labs discuss Moonlight, a non-custodial privacy protocol for Stellar, alongside David from LumenShade, which uses zero-knowledge proofs for privacy pools. Both projects aim to enable private payments on Stellar while maintaining compliance with regulations.

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.

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.

Freely built a payout system on Stellar that lets businesses split payments across multiple recipients in different countries. Using smart wallets, policy signers, and anchors, the team created a secure, low-cost solution for remittances and bulk disbursements, launching mainnet in approximately two months.

Tutorial demonstrating how to build a passkey-enabled smart wallet application on Stellar using PasskeyKit, enabling biometric authentication and decentralized user credential systems without centralized backends.

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.

Caio Matos, CEO of NierX, announces Hack Meridian, a global blockchain hackathon coming to Rio de Janeiro on September 15-16, 2025, hosted at Copacabana Palace with 50,000 USD in prizes and 500 developers from 30+ countries competing across DeFi, Composability, and Open Innovation tracks.

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.

Alex from Script3 provides a comprehensive overview of Blend, a liquidity protocol primitive on Stellar that enables permissionless lending markets with flexible parameters, backstop insurance modules, and multiple integration points for developers building on Soroban.

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 is a new developer tool from Aha Labs that provides a ready-to-use web3 app template for building on Stellar. It includes contract examples, wallet integration, and local network setup to eliminate boilerplate and accelerate dApp development.
