For legal professionals
Co-sign Web3 legal opinions. Keep your client, your diligence, and your standards.
You already write opinions for crypto clients on this corridor. LEXI makes the opinion verifiable and your record of practice portable, without changing who your client is or whose judgment controls. Here is the whole arrangement, liabilities first. V0 runs on Base Sepolia (testnet); mainnet is targeted post-audit, Q4 2026.
LEXI is not a law firm. A credential is not a licence, a registration, or an approval by any regulator. Co-signers on LEXI are licensed lawyers only.

What you sign
A legal opinion, in your name, on a question you scoped.
The LEXI engine's first pass reaches you as input material: a checklist, a document review, a risk read. It is work product, labelled that way, and it is never the opinion. No opinion exists until you sign it, and no AI signs anything.
What exactly you are signing
A co-signed legal opinion: your conclusion, after your own diligence, on the question your scope defines. You review the engine first pass, test it, and co-sign only what your own judgment supports. The engine is in development on a proprietary corpus of real regulatory work; its output is prepared for you, not for the client.
Who your client is
Your firm's client is the protocol, exactly as it would be without LEXI. Collaboration runs on an engagement: a workspace tied to one protocol, one firm and one jurisdiction. Your firm assigns the signatory, the licensed lawyer authorised to co-sign. The protocol retains your firm directly and pays the retainer outside LEXI. LEXI takes no share of your fee, and 0% of protocol revenue goes to the co-signing lawyer.
What your exposure looks like
Tighter than an opinion letter you would write today, by design. Scope is hashed: the credential binds the precise question covered and what is excluded, so nobody can quietly stretch what you opined on. Reliers are named: reliance attaches only after a named relier accepts the reliance terms, and every reliance is recorded. By default you whitelist who may rely (Selective mode); Open reliance, if you ever choose it, requires a defined liability cap in the terms before it is offered. It is dated and it expires: your opinion speaks as of its date, and its on-chain status (Live, Expired, Revoked) is public, so no one relies on a stale opinion by accident.

The stake
A bond behind the signature, and narrow rules on what can touch it.
To be eligible to co-sign, a licensed lawyer posts an eligibility stake: a USD-pegged amount of about $5,000 in $LEXI, re-pegged so the dollar cost stays stable, with a 14-day unbonding period. It is a good-faith bond in the protocol design. No $LEXI token has been issued, so no stake is posted today.
The rules are deliberately narrow. Slashing is committee-adjudicated for proven misconduct only, capped in basis points. Reliers flag disputes; they do not decide them, and they cannot slash. Nobody is slashed because a regulator disagrees with an opinion. The slashing conditions are a governance matter.
Customers never need $LEXI; only co-signers stake. Stake documentation, without price, value or return talk: how $LEXI works.
What you get
Your hours go into judgment, not collation.
Work that arrives prepared
A protocol submits once. Its documentation is already structured and the engine's first pass is already run when the matter reaches you, on a corridor you already serve. The questions left are the ones only a licensed lawyer can answer.
A portable record of practice
Every credential you co-sign is a dated, public artifact: the signatory and firm ID, the jurisdiction, the as-of date and the status are on-chain. That record follows you, not a directory listing. The opinion body itself stays off-chain, encrypted, open only to named reliers.
A voice in governance
Staked lawyers take part in governing jurisdiction expansion, fee parameters, slashing conditions and the treasury. Holders never vote on whether a protocol is compliant; that question is yours alone, in the opinion you sign.
The open items
Two questions deserve a direct conversation, not marketing copy.
For context, not endorsement: VARA's Regulations 2023 (Part IV.A.5) treat duly registered practising lawyers as professionals authorised by a competent professional body who maintain professional indemnity insurance, which is the same bar LEXI's licensure check and the open insurance item describe. LEXI is not licensed or endorsed by VARA.
The founding panel
What happens after you apply.
LEXI is onboarding a small founding panel of licensed lawyers before mainnet, VARA (Dubai) first. The EU (MiCA) and India (FIU-IND) are V1, next up, and lawyers licensed there are welcome to apply now.
Application.
Name, jurisdictions of licensure, registration reference, one line on your practice. Please do not include confidential or privileged information at this stage.What we ask for: who you are and where you are licensed.
Licensure and conflicts check.
Manual and human, in V0. We verify your registration with the issuing bar or register and check for conflicts against the engagement before any matter reaches you.What we check: that you are a practising lawyer in good standing.
Panel onboarding.
Terms in writing, an engagement walkthrough, and the credential schema before it is final. Founding lawyers set the standard the panel is held to.What you get: the arrangement in writing, marked draft where it is draft.
Your licence is checkable by anyone who relies on you.
The signatory and firm ID are public on-chain fields. A relier can check the signatory's licence with the issuing bar or register. For a Dubai-registered signatory, the Government of Dubai Legal Affairs Department publishes a public directory of advocates and legal consultants showing status, registration number and licence expiry. Registration-number lookups work; the directory covers Dubai (onshore) registrations only.

- VARA (Dubai) is the V0 jurisdiction, on Base Sepolia (testnet). What LEXI does and does not do there: VARA compliance (Dubai).
Want the arrangement in writing before applying? Ask for the signatory terms overview in your message and we will send what exists today, marked draft where it is draft. Applying commits you to nothing.
Questions licensed lawyers ask
Four short answers.
Why are LEXI's co-signers licensed lawyers only?
LEXI's co-signers are licensed lawyers because a legal opinion is a professional act that bar and registration rules reserve to lawyers, and because the one VARA rule that names a signer (Annex 2 of the Issuance Rulebook, asset-referenced virtual assets) names a duly registered practising lawyer and excludes internal counsel. Compliance officers do not stake or co-sign on LEXI. They appear as readers: the people at exchanges and VASPs who check a credential before relying on it.
Can a relier slash a co-signing lawyer's stake?
No. Reliers flag disputes; a committee adjudicates them. Slashing requires proven misconduct and is capped in basis points. Nobody is slashed because a regulator disagrees with an opinion, and $LEXI holders never vote on whether a protocol is compliant.
Can a licensed lawyer apply before mainnet?
Yes. LEXI is onboarding a small founding panel of licensed lawyers before mainnet, VARA (Dubai) first. V0 runs on Base Sepolia (testnet) and mainnet is targeted post-audit, Q4 2026. Applying commits you to nothing. No $LEXI token has been issued, so no stake is posted today.
