How to Verify a MetaMask Walletfor Lending or Compliance

MetaMask verification uses cryptographic message signing to prove wallet ownership - no custody, no private key exposure. Accredifi standardizes this for institutional workflows.

Common misconceptions

MetaMask verification is not MetaMask KYC

MetaMask is wallet software. It does not provide built-in identity verification or compliance tooling. Wallet ownership must be verified through a separate infrastructure layer.

MetaMask does not provide KYC

MetaMask is a wallet client. It does not perform institutional identity checks or compliance onboarding.

Ownership ≠ identity

A wallet signature proves key control, not legal identity. It should complement your existing AML/KYC workflow.

Signing proves control

When a user signs a structured challenge, the signature proves they control the wallet - without exposing the private key.

How it works

Message signing proves wallet control

Issue a challenge, collect a signature, verify it, and keep a reusable record. No custody required.

1. Request a signature

Present a nonce-based challenge containing context, purpose, and expiry. The user signs it in MetaMask.

2. Verify cryptographically

Validate that the signature resolves to the expected address. This proves wallet control at that moment.

3. Store and reuse

Save the signed proof as an institutional record for audits, underwriting, and repeat verification.

For institutions

Standardize wallet verification in your workflow

Embed MetaMask verification into onboarding, underwriting, or compliance review - and automate it via API.

Request verification

Trigger a MetaMask verification request during onboarding, underwriting, or compliance review.

Store records

Keep signed proofs and metadata as institutional records for audits, case management, and policy reviews.

Automate via API

Integrate endpoints and webhooks to reduce manual review and scale verification across your platform.

Security by design

No custody
No key exposure
User retains control
FAQ

Frequently asked questions

No. MetaMask is wallet software and does not provide built-in identity verification. Wallet control can be proven cryptographically, but identity checks must be handled by your institution's KYC process.

You issue a structured challenge message and the user signs it in MetaMask. The signature proves control of the wallet's private key, while the private key itself never leaves the wallet.

It proves wallet ownership or control at a point in time. It does not, by itself, prove legal identity. Institutions typically combine wallet verification with existing AML/KYC checks.

Yes. Accredifi provides API endpoints to create verification requests, receive completion events, and fetch signed records so your platform can automate verification in lending and compliance workflows.

Yes. Each verification can be stored as a timestamped institutional record with challenge details, signature validation, and wallet address context for later review, underwriting, and audit trails.

No. Accredifi is a verification infrastructure layer. Funds remain in the user's wallet, and no asset transfer is required to complete verification.
