Reclaim Protocol

Reclaim Protocol is a verification service built on zkTLS, a way to prove what a website showed you without sharing your password. It is the tool at reclaimprotocol.org, not the "reclaim" coins in the Blue Protocol game.

A user logs in to a site they already use, such as a payroll or university portal. Reclaim Protocol then makes a proof of one fact, like an employer name or a student status. The app that asked sees only that fact.

Most customers use it to check jobs, income and student status without document uploads. Developers can also verify the proofs inside a Solana program. The company is backed by Y Combinator (Winter 2021) and has no token.

How Reclaim Protocol zkTLS works

Reclaim Protocol sends your web session through a helper server, called an attestor. The attestor confirms the data really came from the named website. It sees only scrambled traffic, so it never learns your password or the rest of the page.

Your phone or browser then runs a zero-knowledge proof. That is maths showing a statement is true without revealing the data behind it. The proof picks out the one value the app asked for. The attestor signs the result, and the app can check it on its own servers or on a blockchain.

Each data source is called a provider. A provider is a web address plus a pointer to where the value sits on the page. The developer docs offer ready-made providers, and you can build your own.

The design is written up formally in a September 2026 IACR ePrint paper by Andrey Bozhko (University of Luxembourg) and Kirill Kutsenok (Reclaim Protocol, King's College London). The paper reports attesting a 1,200 kB response in about 7.3 seconds on a mid-range phone.

Reclaim Protocol employment, income and education verification

Reclaim Protocol's main product checks job and study claims straight from the source. The user does not upload a payslip or transcript, which AI tools can now fake. They log in to the real system, and Reclaim returns a proof of the one field you asked for.

For students, the education page claims more than 29,000 universities in over 190 countries. It asks the registrar at the time of the check, so the result is live.

For jobs and income, the homepage lists payroll systems such as Workday, ADP and Gusto. It also lists shop and airline loyalty accounts. Y Combinator's company page quotes conversion above 45%. That means nearly half of users asked to verify finish the flow.

If you run a lender, a hiring platform or a student discount scheme, this replaces document review with a check that returns in seconds.

zkFetch and the Reclaim AI agent integration

zkFetch is Reclaim Protocol's tool for proving what an API sent back to your server. No end user is involved. You call the API, and zkFetch gives you a proof of the reply that others can check. That suits prices, scores or account data you want others to trust.

The docs now lead with an AI agent route. You ask a coding agent, such as Claude Code, Codex or Cursor, to build a provider for a website. The user side works the same way. You send a link, the user connects the account, and "Reclaim's AI retrieves the information you need," per the homepage.

Co-founder Madhavan Malolan wrote on 16 October 2026 that the team is working on an "AI first flow." You define the claim and the source you trust. The AI then works out how to make the proof. This is a plan, not a finished product.

Verifying Reclaim proofs on Solana and other chains

Reclaim Protocol proofs can be checked by a Solana program, so an on-chain app can gate an action on a real-world fact. The verifier program is deployed at rEcLDWaVLaymz82eGr6cutosPxE6SEzw6q4pbtLuyqf on mainnet, testnet and devnet, per the Solana integration repo.

The Solana quickstart uses Anchor. You serialise the proof, send it to your program, and run the verification inside it. After deploying, you initialise "epoch" accounts with the SDK's scripts. The repo includes an airdrop example, where only users who prove a fact can claim.

Solana is one of many targets. The on-chain SDK list includes Solana, Solidity (for EVM chains), Aptos, Sui, Near, Starknet, Stellar, Cosmos, Polkadot, Cardano, Mina and others. Front-end SDKs cover JavaScript, React Native and Flutter.

Reclaim Protocol pricing and free tier

Reclaim Protocol sells verifications in monthly bundles, with a free tier for testing. The published plans are:

Per check, that works out to $1.00 on Solopreneur and $0.50 on Startup. Y Combinator's listing says costs fall below a dollar per verification. A Solana app that verifies only a few users a month can stay on the free plan.

Who Reclaim Protocol is for

Reclaim Protocol fits teams that need a fact about a user that sits behind a login. You must be able to wait a few seconds for the proof. Typical buyers are lenders, hiring platforms, student and loyalty discount schemes, and on-chain apps that need a real-world credential.

It suits you less if the fact is already on-chain. It also fails if your users won't log in through a verification link. Beyond 25 checks a month it is a paid service, so a busy hobby project will hit the pricing fast.

For a Solana developer, the clearest use is gating: an airdrop, a loan or a role that opens only after a user proves something off-chain, checked by your own program.

Is Reclaim Protocol safe? Audits, attestors and upgrade keys

Reclaim Protocol has been audited and holds standard compliance certificates, but its security still depends on its attestor servers behaving honestly. An attestor that colluded with a user could sign a false claim. Zellic's audit raised "node centralization risk" as a discussion point for this reason.

Audits and their scope:

• Zellic reviewed the TLS library, receipt verifier, witness SDK, app and developer SDK from 27 February to 21 March 2024. It reported 4 critical, 2 high, 5 medium and 6 low findings.
• zkSecurity audited the ChaCha20 zero-knowledge circuits in 2023.
• Neither public report covers the Solana verifier program.

The trust centre lists SOC 2 Type II, ISO 27001 and GDPR readiness. It names AWS and Google Cloud confidential computing (TEE) as subprocessors, and Anthropic for AI analysis of logs. The Solana Explorer shows the Solana program as upgradeable, controlled by one address (reaDY5gysDQhMeWPUXTUiyLQnsrQz7bWJHNv9rqFJKY). We could not confirm whether that address is a multisig, so assume whoever holds it can change the verifier.

Two practical risks remain. Websites change their layouts, which can break a provider until it is fixed. And users sign in to their real accounts through a link, so phishing is a risk, which Zellic also flagged.

Reclaim Protocol vs zkPass, Opacity and other zkTLS alternatives

Reclaim Protocol is the zkTLS option most focused on business job and study checks. Its rivals are mostly crypto projects aimed at on-chain apps.

zkPass is another zkTLS project. Its developer docs show how to check its proofs on Solana. Opacity Network also builds zkTLS on Solana. Our podcast summary with the Opacity team covers why they chose Solana.

The key trade-off is trust against speed. Reclaim Protocol uses one helper server per proof, which keeps it fast enough for phones. Other designs, such as the academic DECO system, split trust across several parties. They ask less trust of any one server but need more computing time. For a ready-made HR and student product, Reclaim Protocol is further along.

Reclaim Protocol token, founders and funding

Reclaim Protocol has no token. Searches for a "reclaim token" usually mean the Blue Protocol: Star Resonance video game. Reclaim Protocol's own site and docs mention no token or airdrop. It is also unrelated to getting back SOL locked in empty token accounts. That is a different job, and Solana Compass runs a free tool that closes empty token accounts.

The company behind it is CreatorOS Inc, based in Hyderabad, India. Y Combinator lists Madhavan Malolan as founder, leading product and research. Sriharsha Karamchati is co-founder and works on zkTLS. YC's page lists a $10 million Series A, a 2021 founding date and a team of 17.
