For lending, underwriting, and compliance

Verify self-custodyfor financial workflows

Accredifi turns wallet ownership and balances into cryptographic proof that lenders, fintechs, and compliance teams can verify without custody.

The verification layer between wallets and financial systems

Accredifi verifies wallet control at signing time, captures balance snapshots as supporting evidence, and makes the result available to institutional workflows through structured records.

Verification is not a moment. It's a lifecycle.

Proof persists, balance evidence is recorded, and reverification keeps the relationship current.

What this proves

Verification evidence your financial workflow can defend.

Accredifi separates cryptographic ownership proof from supporting balance evidence, then records both in a way institutions can review, reverify, and audit.

Control at signing

A valid signature proves the user controlled the wallet at that point in time.

Balance snapshot

Balances are captured as supporting evidence alongside the ownership proof.

Tamper-evident record

Timestamps, signatures, and verification history create defensible evidence.

Scheduled reverification

Recurring signing keeps access relationships current when workflows require it.

Self-custody needs verification infrastructure.

Clients increasingly hold assets in self-custody wallets. Lenders, fintechs, and compliance teams still need evidence they can evaluate, retrieve, and recheck without taking custody. This is the gap Accredifi closes.

Wallet control, proven at signing
Wallet owners sign a challenge. Institutions receive timestamped proof that the wallet was controlled at that moment.
Verification without custody
No key transfers, asset movement, or custody exposure. Balances are captured as supporting snapshots.
Records your systems can use
Verification status, proof history, balance evidence, and reverification schedules are available through API.

The verification lifecycle

From request to ongoing verification state

A single signing event proves wallet control. The product around it turns that event into evidence your institution can operate against.

01

Request access

Create a verification request from your workflow, by hosted link, or through the API.

02

User signs

The wallet signs a message that proves control at that point in time. No custody or key access.

03

Record issued

Accredifi stores the proof, timestamp, and balance snapshot as structured evidence.

04

State maintained

Status, history, and reverification schedules keep the record current for downstream systems.

Institutional use cases

Where wallet verification enters the workflow

Accredifi gives teams a structured way to verify self-custodied crypto before decisions, reviews, and recurring checks.

Crypto-backed lending

Verify wallet control and supporting balances before underwriting a collateral-backed loan.

Client onboarding

Replace screenshot-based proof of funds with timestamped evidence tied to the wallet owner.

Ongoing compliance

Run scheduled reverification so wallet evidence stays current after the initial review.

Mortgage deposits

Evaluate crypto proof of funds without requiring liquidation, transfers, or custody.

Legal and estate

Create timestamped wallet records for proceedings, estate planning, or regulatory review.

Investment platforms

Confirm wallet-based proof of funds for fund minimums, private deals, and platform eligibility.

One verification layer for both sides of the workflow

Users retain self-custody. Institutions receive structured evidence they can review, store, and recheck.

Self-custody stays intact

Individuals

Prove wallet control when a lender, platform, or compliance workflow needs evidence. Your keys stay with you and assets do not move.

FAQ

Frequently asked questions

No. Never. We never request transfers, approvals, or access to your private keys. We only request a cryptographic signature to prove ownership, and we capture balance snapshots via view-only access. Your assets stay in your wallet at all times.

Screenshots can be faked. Our cryptographic signatures prove you control the private key without revealing it. Institutions can verify the proof on-chain, making it tamper-proof and trustworthy.

Only the institutions you explicitly grant access to. You set expiry dates, and you can revoke access at any time. We don't share your data with anyone else, and you can see exactly who has access in your dashboard.

The institution immediately loses access to your wallet data. They're notified via webhook, and any cached data becomes invalid. You maintain full control over who sees what, and when.

Institutions receive a cryptographically signed snapshot that they can verify on-chain. The signature proves you control the wallet, and the snapshot shows balances at a specific point in time. It's tamper-proof and auditable.

We support Bitcoin (BTC) and Ethereum (ETH) via MetaMask, Trezor, and BitBox. More chains and wallets are coming soon.

Yes. Our REST API lets institutions create access requests, receive webhooks for approvals and revocations, and retrieve wallet data programmatically. Full documentation is available for registered institutions.

Quantum Won’t Break Bitcoin First. It Will Break Proof of Funds.

Quantum Won’t Break Bitcoin First. It Will Break Proof of Funds.

Quantum computing is often framed as an existential threat to Bitcoin. The earlier impact is likelier to be subtler: a loss of confidence in static cryptographic proofs, and with it, the reliability of crypto evidence in financial workflows.
