Verify MetaMask wallet controlfor financial workflows
Accredifi lets institutions request proof that a user controlled a MetaMask Ethereum wallet at signing time, capture balance evidence, and reverify on a schedule without taking custody.
MetaMask proves control, not identity
A MetaMask signature is powerful evidence, but it is not a full compliance workflow on its own. Accredifi turns that signature into a structured record institutions can use alongside their existing onboarding, underwriting, and AML/KYC processes.
Wallet control at time T
A valid signature proves the user controlled the wallet when they signed. It does not permanently prove future control.
Balance is adjacent evidence
Balances are fetched and recorded separately. Institutions should treat ownership proof plus balance at time T as the useful attestation.
Policy stays with the institution
Accredifi supplies tamper-evident evidence. How that evidence supports lending, accreditation, AML, or compliance decisions remains your policy.
From access request to audit-ready record
A MetaMask verification is not just a signing prompt. It is a recorded workflow that starts with an institution request and can continue through scheduled reverification.
1. Create an access request
The institution creates an email or one-time link with the requested wallet data and optional verification schedule.
2. User signs in MetaMask
The user accepts the request and signs a one-time Ethereum message in the MetaMask extension or mobile wallet. Accredifi verifies the signature against the public account address.
3. Record and reverify
Wallet access is granted, evidence is stored, and scheduled reverification can require the user to sign again when due.

Why verify a MetaMask wallet?
MetaMask verification uses Ethereum message signing, not a transaction. It is built for DeFi, stablecoin, OTC, and treasury users who need fast proof of wallet control from a browser extension or mobile wallet.
No gas required
Users prove control with a signed Ethereum message rather than an on-chain transaction, so verification does not require gas.
Ethereum-native proof
Capture evidence for ETH, ERC-20 stablecoins, and Ethereum account workflows using the address and signature the user provides.
Fast verification
The browser and mobile signing flow keeps verification lightweight for onboarding, lending, compliance, and treasury review.
| Wallet | Best for | Verification method | Why it matters |
|---|---|---|---|
MetaMask | DeFi, ETH, and stablecoin users | Browser/mobile message signing | Fast Ethereum wallet proof without gas or transactions. |
| Long-term BTC and ETH holders | Hardware message signing | High-confidence evidence for large balances. | |
| Bitcoin-focused self-custody users | Hardware message signing | Bitcoin-first address-control evidence without moving coins. | |
| Privacy-conscious Bitcoin holders | Hardware message signing | Scoped proof for privacy-conscious self-custody users. |

Track lifecycle state
Use webhooks and verification schedules to handle access grants, revocations, due dates, and overdue reverification.
What never changes
Frequently asked questions
No. Signing a verification message in MetaMask is not an on-chain transaction, so it does not require gas. It proves control of the private key for the address that produced the signature.
No. Connecting exposes a selected public address to the site. Verification requires the user to sign a specific one-time message so the signature can be checked against that address.
No. MetaMask is a wallet, not an identity provider. It can help sign messages that prove wallet control, but legal identity, AML, and KYC decisions remain part of your institution's own workflow.
Accredifi creates a one-time signing request. The user signs it through MetaMask using an Ethereum message-signing prompt, Accredifi verifies the signature against the public address, and the private key never leaves the wallet.
It proves the user controlled the wallet at the time of signing. It does not prove current control forever, and balance data is supporting evidence captured separately at a point in time.
Yes. Institutions can create access requests by API or link, receive events when access is granted or verification is completed, and retrieve balances, addresses, and verification records for their systems.
Yes. Verification schedules can require the user to sign again on a recurring cadence, such as monthly. Due windows and overdue actions can be configured for ongoing assurance.
No. Accredifi verifies wallet control without taking custody. Funds remain in the user's wallet, and no asset transfer is required to complete verification.
