Speaker presents a boilerplate starter pack for the Easy A Stellar Hackathon (Oct 12, London), featuring a Soroban smart contract with key-value storage and a React dapp using the Stellar SDK. Also covers passkeys for passwordless authentication and the Anchor protocol for TradFi integration.

James Puccini demonstrates how to build passwordless smart wallets on Stellar using WebAuthn passkeys and Soroban contracts, enabling seamless biometric authentication without traditional wallet setup.

Developer demonstrates major smart wallet updates for Soroban including P256R1 and ED25519 signing curves, multi-signature support, and policies that restrict signer capabilities without requiring transaction pop-ups.

James Pacini, Stellar developer in residence, provides a comprehensive tutorial on building Rust-based smart contracts using the Soroban SDK, covering deployment, data types, testing, and creating a decentralized application to interact with contracts on the Stellar network.

Comet is a fuzzing and formal verification tool for Soroban smart contracts. The demo walks through testing a vaults contract using property-based testing, showing how to write test contracts that interact with target contracts and use the Comet CLI to run automated fuzzing on contract functions.

BlockScience and Stellar Development Foundation presented NeuroQuorum Governance (NQG), a sophisticated governance framework combining neural governance with quorum delegation. The system has been implemented in the Stellar Community Fund, allocating over $15 million in XLM across 300+ submissions since October 2023.

Chris Anataglio from the Stellar Development Foundation walks through building Soroban smart contracts using Rust, covering Okashi browser IDE and the Stellar CLI with live coding examples.

Tomaso de Ponti, a 19-year-old Stellar consultant and co-founder of X-Cyclo Labs, discusses Soroban development roadmap including elliptic curves for zero-knowledge proofs, passkeys for smart wallets, and Mercury indexer infrastructure.

CoinFabric, a blockchain security and auditing firm, discusses smart contract vulnerabilities, the importance of manual security audits over automated tools, and their grant-funded work with Stellar to develop static analysis tools for Soroban developers.

Garen Tyson from SDF explains Stellar's state archival protocol, which solves blockchain state bloat by charging rent for storage instead of one-time fees. Archived entries can be restored via Merkle proofs, with RPC nodes handling complexity transparently for users and developers.

Elliot from the Stellar Development Foundation demonstrates how to build passkey-authenticated smart wallets on Stellar using PasskeyKit and LaunchTube, eliminating the need for traditional wallet setup and seed phrases.

Julian Martinez from SDF walks through building full-stack dApps on Stellar using Soroban smart contracts, covering frontend integration with Freighter wallet, TypeScript bindings, and deploying a crowdfunding example dApp to production.

Stellar and Solana developers discuss state bloat solutions: Solana's compression and binary trie approach versus Stellar's rent-based system with sharded Merkle trees. Both aim to balance low fees with preventing spam while maintaining data availability.

Julian Martinez from SDF walks through Rust smart contract development on Soroban, covering basics like data types and storage, then advances to a staking contract example with cross-contract calls and testing.

Workshop session on using Mercury indexer to query Stellar blockchain data without direct RPC calls. Covers setting up subscriptions, querying ledger entries, parsing XDR data, and practical examples with voting contracts.

Paltalabs team demonstrates building a voting dApp frontend connected to Soroban smart contracts, covering wallet integration, contract invocation, and transaction signing with Soroban React library.

Spanish-language peer programming session building a voting smart contract on Soroban, Stellar's smart contract platform. Developers walk through contract development, testing in Rust, and deployment to testnet using Docker, CLI tools, and JavaScript SDK.

Tutorial on building a custom faucet for the Stellar testnet using JavaScript SDK. Demonstrates creating assets, managing accounts, and distributing tokens through a web interface.

Tutorial walkthrough for executing bridge transactions on Soroswap, covering wallet connection, asset selection, amount entry, transaction confirmation, and blockchain verification via StellarChain explorer.

Ana Rodriguez from Scale Mode teaches Topic 7 of the Stellar course organized by Errorgentina Programa and Haciendo Stellar, covering how to interact with the Stellar Laboratory. The session explains the differences between Testnet and Pubnet, then demonstrates practical use of the Laboratory for creating accounts, querying endpoints, building transactions, signing, and submitting them.

Ana Rodriguez teaches Stellar transactions and operations in Spanish, covering how to construct, validate, and submit transactions to the Stellar network with practical code examples using the JavaScript SDK.

Enrique from Crate Technologies discusses xBull Wallet, an open-source wallet for advanced Stellar users with hardware wallet support, and Soroban Domains, a protocol enabling human-readable usernames to replace public keys on Stellar.

Spanish-language tutorial introducing Stellar accounts, covering key pair generation, account creation, trust lines, sequence numbers, thresholds, signers, sponsored reserves, and account deletion via merge operations.

Educational video introducing payments on the Stellar network, covering basic payment operations, claimable balances, and practical TypeScript SDK examples for implementing cross-border transactions with asset conversion.
