Accredifi turns wallet ownership and balances into cryptographic proof that lenders, fintechs, and compliance teams can verify without custody.
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.
Accredifi separates cryptographic ownership proof from supporting balance evidence, then records both in a way institutions can review, reverify, and audit.
A valid signature proves the user controlled the wallet at that point in time.
Balances are captured as supporting evidence alongside the ownership proof.
Timestamps, signatures, and verification history create defensible evidence.
Recurring signing keeps access relationships current when workflows require it.
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.
A single signing event proves wallet control. The product around it turns that event into evidence your institution can operate against.
Create a verification request from your workflow, by hosted link, or through the API.
The wallet signs a message that proves control at that point in time. No custody or key access.
Accredifi stores the proof, timestamp, and balance snapshot as structured evidence.
Status, history, and reverification schedules keep the record current for downstream systems.
Accredifi gives teams a structured way to verify self-custodied crypto before decisions, reviews, and recurring checks.
Verify wallet control and supporting balances before underwriting a collateral-backed loan.
Replace screenshot-based proof of funds with timestamped evidence tied to the wallet owner.
Run scheduled reverification so wallet evidence stays current after the initial review.
Evaluate crypto proof of funds without requiring liquidation, transfers, or custody.
Create timestamped wallet records for proceedings, estate planning, or regulatory review.
Confirm wallet-based proof of funds for fund minimums, private deals, and platform eligibility.
Users retain self-custody. Institutions receive structured evidence they can review, store, and recheck.
Self-custody stays intact
Prove wallet control when a lender, platform, or compliance workflow needs evidence. Your keys stay with you and assets do not move.
Verification infrastructure
Add wallet verification to lending, onboarding, and compliance flows. Create requests, retrieve records, and track verification state.
Accredifi integrates with leading crypto wallets to ensure secure, non-custodial verification.
More wallets and blockchains coming soon
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.

A crypto wallet verification API should do more than collect addresses or screenshots. Institutions need proof of wallet control, timestamped proof of funds, reusable records, reverification, and audit-ready evidence without taking custody.
Wallet Proof Links let users create secure, shareable proof-of-funds pages for self-custodied Bitcoin and Ethereum wallets, using cryptographic signatures instead of screenshots.
Regulatory scrutiny of unhosted wallets is not simply a threat to self-custody. It is a signal that financial institutions need wallet verification, proof of control, reusable attestations, and audit-ready crypto evidence.
