David Mazuris introduces STC, the Stellar Transaction Compiler, a command-line tool that makes it easier to create, examine, and debug raw Stellar transactions without writing code. The tool translates between XDR and TxRep formats, enabling developers to test transaction behavior directly on the network.

Tyler Vanderhoeven presents Stellar Quest, a gamified technical onboarding platform launching Monday with eight challenges designed to teach developers about Stellar through hands-on tasks, XLM prizes, and collectible badges.

Devnil from SDF's Voyager team presents the first version of Stellar's data analytics system, built on BigQuery and Kubernetes to enable fast historical queries and network insights. The system powers internal business analytics and will soon support real-time data, improved observability, and public visualizations.

Morley Zai from Vibrant explains how the app handles deposits and withdrawals using Stellar anchors and the SEP-24 protocol. The soft-launched Argentina-focused app lets users convert local currency to USD tokens on Stellar through a streamlined mobile interface.

Django Polaris is an extendable Django application that enables developers to build Stellar anchor servers implementing SEP standards. The talk demonstrates installing, configuring, and deploying a complete SEP24 anchor with deposit and withdrawal flows using integrations for custom banking rails and KYC.

Stellar Development Foundation held an open protocol discussion covering CAP 23 (claimable balances for two-part payments) and CAP 33 (sponsored reserves). Teams debated predicate tree recursion depth limits, SEP 30 compatibility issues, and downstream SDK/Horizon implementation readiness for Protocol 14.

Oleg Andreev from Stellar presents Slingshot and ZKVM, a modular suite combining zero-knowledge proofs, confidential transactions, and a programmable virtual machine to enable private, auditable blockchain transactions with customizable smart contract conditions.

Stellar Development Foundation hosted the first open protocol discussion, a bi-weekly meeting to review Core Advancement Proposals (CAPs) for protocol improvements. The meeting covered CAP 23 (claimable balances), CAP 33 (sponsored reserves), protocol 13 upgrade delay, and improvements to the CAP process.

Nicholas Haraf from the Stellar Development Foundation demonstrates Kelp GUI v1, a graphical interface for managing trading bots on the Stellar Decentralized Exchange. The tool allows users to create and manage multiple bot instances with customizable trading strategies without coding.

Colton from the Stellar Development Foundation discusses best practices for building usable Stellar applications, covering Stellar Ecosystem Proposals (SEPs), interface simplification, and user education strategies.
