Stellar Developers meeting featuring Renat's presentation on zero-knowledge group membership proofs for Soroban contracts, followed by Kaan's overview of AI orchestration tools like Paperclip for developer workflows.

Educational tutorial on developing smart contracts with Soroban, Stellar's WebAssembly-based smart contract platform. Covers the 7-step process from CLI installation to contract deployment and invocation on testnet.

Type Zero is a web3 typing game built on Stellar that uses RISC Zero's ZKVM to generate zero-knowledge proofs verifying game scores on-chain. All game logic is deterministic and verified through Soroban smart contracts, eliminating trust in frontend or backend.

Tutorial demonstrating how to write zero-knowledge circuits in Noir, compile them to R1CS, generate Groth16 proofs with Snark.js, and verify them on Stellar blockchain via smart contracts.

Stellar Protocol 25 Project X-Ray ships native ZK primitives (BN254, Poseidon) to mainnet. Boundless Networks verifier and Nethermind's Grot16 implementation enable production-ready privacy infrastructure with configurable compliance for institutions.

Stellar Protocol 25 (Project X-Ray) launches native ZK primitives including BN254 and Poseidon, enabling production-ready privacy infrastructure. Boundless verifier and NetherMind's Groth16 implementation are now live on Stellar Mainnet, allowing developers to build configurable, compliant privacy applications.

A tutorial demonstrates building a rebasing token (RUSD) on the Stellar blockchain that accepts USDC deposits and automatically accrues yield by increasing holders' balances. The token uses a share-based system where added collateral, simulating yield from protocols like Blend, proportionally boosts all users' balances without needing to stake or interact further. Users can hold RUSD in their wallets and watch balances grow in real-time.

Stellar protocol discussion covering three CAPs: CAP-78 on improved DTL extension management for contracts, CAP-79 adding host functions for muxed address conversions, and CAP-77 proposing a protocol-level mechanism to freeze corrupted ledger entries during emergencies.

A technical walkthrough of an auto-compounding USDC vault built on Stellar using Blend Protocol, OpenZeppelin vault libraries, and Comet DEX. The vault automatically claims BLND rewards, swaps them to USDC, and reinvests them for users.

Developer builds a selective disclosure KYC system using zero-knowledge proofs and BLS ring signatures on Stellar Soroban. Users can prove attributes like residency or age without revealing full identity, with credentials verified on-chain while personal data stays off-chain.

OpenZeppelin presents their managed Stellar Relayer service with a channels plugin for parallel transaction processing. The service enables gasless, high-throughput transactions on Stellar with automatic fee bumping and sequence number management.

Developer demonstrates a zero-knowledge login system built on Stellar using ring signatures and BLS12381 cryptography, enabling users to prove access rights without revealing identity.

CAP75 proposes adding two native host functions to Soroban for Poseidon and Poseidon 2 permutations, enabling efficient zero-knowledge proof operations on BLS and BN254 fields without expensive contract-side implementations.

Pam and Willem from AHA Company introduce the Stellar Registry and Registry CLI, a package manager for Soroban smart contracts that enables human-readable naming, versioning, and simplified contract deployment and upgrades on Stellar.

Tutorial on creating and distributing tokens on Stellar using Merkle trees for efficient airdrop verification. Demonstrates building a token contract with claim functionality, using Soroban smart contracts and a React frontend.

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.

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.

OpenZeppelin's Bojan discusses the Stellar Contracts Library, built in under a year with four audits completed. The library provides foundational smart contract tools including tokens, access controls, and innovative features like smart accounts with passkeys and real-world asset tokenization tailored for Soroban.

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.

Lucien from Boundless and Matteo from NetherMind demonstrate how to bring zero-knowledge proofs to Stellar via Boundless, enabling privacy, removing transaction limits, and unlocking new DeFi applications like private AMMs through verifiable off-chain computation.

Garant from Stellar Development Foundation presents Protocol 23 (WISC) performance enhancements for smart contracts, including parallel transaction execution via conflict-free parallelism, in-memory state caching, and reusable module caching that reduce instruction costs by up to 80% and improve network throughput.

Lee from the Stellar Development Foundation discusses three low-level features that power great developer tools: contract specs (embedded IDL), the Soroban runtime environment, and XDR JSON for readable transaction data.

Francesco from Almanacs discusses AI-powered security tools for blockchain, highlighting how AI-generated code increases attack surface and why traditional security tools fall short. Almanacs launches in the Stellar Audit Bank to provide subsidized security scans for Soroban projects.

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.
