🔒 Solana Security Bootcamp
Rektoff, with support from Solana Foundation, has announced a 6-week Rust & Solana security bootcamp.
The program is designed to help developers and auditors learn more about secure systems programming and smart contract vulnerabilities.
The first three weeks focus on Rust internals, memory layout across static, stack, and heap memory, and ownership and lifetimes.
The second half of the program focuses on Solana’s runtime and smart contract execution model. This includes hands-on work with bytecode analysis, fuzzing, and formal security workflows.
A key feature of the bootcamp is a final capstone audit project.
Participants will select an existing Solana protocol, perform a full audit including threat modeling and PoC development, and receive personalized feedback.
The program also includes live sessions, feedback from instructors, verified NFT certificate, and access to a private Slack community of security-focused Rust engineers.
Participation is free, but space is limited to 75 participants. Applications close June 25.

👁️ Squads Passkey Support
Squads Protocol has introduced support for native passkeys and session keys on Solana, utilizing the secp256r1 precompile proposed in Solana Improvement Document SIMD-48.
Passkeys refer to device-native credentials (Face ID or fingerprint authentication) that can be used to sign transactions from secure "enclaves" found in smartphones and password managers. This eliminates the need for traditional private key management in certain use cases.
Session keys provide limited-use, time-bound signing capabilities. They are designed to facilitate secure and seamless app interactions.
An example is a DeFi app that delegates permission for stablecoin transfers to a session key, allowing for controlled automation while maintaining user control and security.
This functionality is currently live on Devnet and will be deployed to Mainnet for both the Smart Account API, advanced account abstraction features for programmable wallets, and Grid, a developer platform tailored for stablecoin-based DeFi applications.

🔎 Anchor Studio
Anchor Studio is a new visual dashboard that speeds up development and debugging for Solana programs built with Anchor.
Upload an Anchor IDL, connect your wallet, and the tool immediately reveals the program’s structure, accounts, and decoded instructions in one responsive workspace with no custom UI or local front-end required.
This matters because testing and debugging Anchor programs often means spinning up ad-hoc interfaces or wading through CLI output.
Anchor Studio replaces that pain with an integrated account explorer, instruction playground, and transaction viewer that surface arguments, logs, and errors in context.
The result is faster iteration and fewer roadblocks when you need to simulate calls, send real ones, or trace issues end-to-end.
🎓 Blueshift 2.0
Blueshift, a Solana developer education platform, has recently launched "v2" with several key updates aimed at enhancing the learning experience for developers.
The update includes splitting content into two formats
- Courses: Comprehensive guides covering everything from basic to advanced concepts.
- Challenges: Hands-on coding challenges that test your skills in real scenarios.
The new courses include and Introduction to Anchor and Introduction to Pinocchio, along with a new Pinocchio Escrow challenge,
Blueshift 2.0 also adds NFT rewards for you to show off your achievements.
✍️ Helius Builders Series
Helius has opened its Builder Series guest blog program with the goal of accelerating research and developer education and creating a space where subject-matter experts can share practical insights and advance discussion around emerging primitives and design patterns.
Authors who contribute gain three main benefits:
- Build authority by attaching their name to in-depth content
- Reach Solana builders through Helius’ website, social feeds and newsletter
- Attract users who discover their work via those channels.
Submissions must present a new, unique angle, be written by a proven expert, dive deep into the details with code-level examples or diagrams, and use jargon-free language that delivers value.
Authors can submit a brief outline. If the idea aligns with the editorial bar, the writer will be invited to develop the full article, with the Helius team handling editing, design, and promotion.
For developers and founders who have solved hard technical problems, the Builder Series offers a way to share those lessons and raise the profile of their projects while contributing knowledge back to the ecosystem.
Introducing the Builder Series Guest Blog Program
🎨 SuperteamNG Design Bootcamp
SuperteamNG is launching a four-week, AI-powered Design Bootcamp starting 30 June 2025.
The remote program covers five tracks:
- Graphic Design
- Brand Design
- Product Design (UI/UX)
- Motion Design
- 2D/3D Animation
Participants will learn using AI-first workflows with tools such as Midjourney, Firefly and GPT prompts, and tackle real-world briefs, build portfolio pieces and receive professional feedback, making the bootcamp a fast way to level-up design skills for global work.
⚠️ SIMD-0191: Relax Transaction Loading Constraints
SIMD-0191, Relax Transaction Loading Constraints, is intended to reduce the types of errors that lead to block rejection by converting errors that currently violate Solana network rules into runtime errors
Protocol violations like missing program accounts or oversize data requests caused validators to discard the transactions after heavy pre-flight checks. They are now runtime errors, which lets validators add the failed transactions to a block, collect the base fee, and let execution abort naturally.
For developers, fewer edge-case checks need to happen before execution, meaning client libraries can drop some workarounds and fee outcomes become easier to predict.
If implemented, Wallets and SDKs must add stronger client-side validation or users will pay fees for transactions that were never executable, test suites that assume “no fee on block rejection” need to be updated, and explorers will have to label these runtime failures clearly.

⚓ Anchor v2 Discussion
Anchor is being modernized in two steps to make it more efficient and optimized.
First, V1 will be a cleanup of the current 0.x versions, including bumping Borsh to 1.x, removing dead code and foot-guns, trimming CU costs, and ending the nightly-generated IDLs.
Version 2 will be a ground-up rewrite that bakes in everything developers have learned since Anchor’s 2021 launch.
The goal is first-class CU efficiency and performance without sacrificing Anchor’s ease of use. Pinocchio will serve as the new entrypoint layer, but most design choices are still open.
Anchor devs are asked to provide feedback on what a next-generation, CU-optimized Anchor framework should look like.
