Solana Soulbound Credentials: Non-transferable, Revocable Tokens
A developer post on DEV (Jul 4, 2026) demonstrates how Solana's Token-2022 extensions can create "soulbound" credentials that are non-transferable yet revocable by the issuer. By enabling the Non-Transferable and Permanent Delegate extensions (plus Metadata) on a mint via the spl-token CLI, transfer instructions are rejected at the protocol level while a designated permanent delegate can burn or move tokens from a holder's account without the holder's signature. The author tested minting, attempted transfer (rejected by Token-2022), and successful issuer-initiated burn. The pattern exists in production — Paxos reportedly uses Permanent Delegate on USDP to claw back illicit funds — raising questions about whether such revocable credentials constitute true ownership or a persistent permission.
Demonstrates native protocol-level support on Solana for non-transferable, issuer-revocable credentials — a technical pattern with implications for digital identity, revocability, and regulatory compliance, but limited immediate impact on mainstream AdTech.

Key Takeaways & Evidence Grounding
- Author Russell Oje published a DEV post on 2026-07-04 demonstrating Solana "soulbound" credentials.
- Solana Token-2022 supports extensions including Non-Transferable (locks token to an account) and Permanent Delegate (lets an authority burn/move tokens without holder signature).
- The author created a mint using spl-token flags --enable-non-transferable, --enable-permanent-delegate, and --enable-metadata.
- A transfer of a non-transferable token was rejected by the Token-2022 program; the issuer used permanent delegate authority to burn a recipient's token without their signature.
- Paxos uses the Permanent Delegate extension on its USDP stablecoin to claw back funds tied to illegal activity, per the article.

Google launches unified agentic AI for Gemini
At a Google Cloud event on Thursday, Google announced it is bringing agentic AI to its Gemini assistant, launching a unified agent that can autonomously plan and execute tasks on behalf of users. Aimed initially at businesses, the agent can connect to internal systems and external tools, use custom skills, and even choose from third-party models like Anthropic's Claude. It will have its own Workspace account with an email address, and will write its own audit trail. Early testers include On, Shopify, and PayPal. Gemini has over 1 billion monthly active users, and nearly 90% of Fortune 100 companies use Gemini Enterprise.
US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
US suspends Microsoft, Adobe from green card labor program
The Trump administration has suspended Microsoft, Adobe, and six other major tech firms—Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro—from the U.S. Permanent Labor Certification program, which facilitates green cards for skilled foreign workers. Secretary of Labor Keith Sonderling cited active federal investigations and alleged fraud, noting that no new or pending applications from these companies will be accepted. Vice President JD Vance accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft defended its practices, stating that most U.S. employees are American and that 80% of its H-1B petitions were for existing employees. The announcement was made during a White House summit on H-1B fraud, and the administration also plans to investigate nine universities, including Harvard, Yale, and Stanford, over student visa program abuse.
