Turn wallet ownership into verifiable, auditable proof for lending, underwriting, and compliance.
No screenshots. No custody. Just proof.
Used in lending, onboarding, and compliance decisions.
Accredifi sits between the user's wallet and your institution. It verifies ownership cryptographically, structures the data for your systems, and maintains an audit trail you can defend.
User

Verification is not a moment. It's a lifecycle.
Proof persists, balances update, and the audit trail grows with every interaction.
More clients hold wealth in self-custody wallets. Lenders, compliance teams, and onboarding flows are being asked to verify it. But there's no standard way to do this. This is the gap Accredifi closes.
Not a one-time check. An ongoing relationship with state your systems can enforce.
Institution creates an access request for the user. Email, one-time link, or API redirect.
User connects wallet and signs a verification message. Proves control without revealing keys.
Cryptographic proof is stored with timestamp. Institution can retrieve data via API.
Verification status tracks over time. Reverification schedules keep the relationship current.
Lending, underwriting, compliance, and onboarding flows that need to verify self-custodied crypto.
Verify collateral before approving loans. API responses your underwriting system can consume.
Replace screenshot-based proof of funds. Evidence that survives compliance review.
Reverify holdings over time. Scheduled checks keep systems current.
Accept crypto as proof of funds. Verifiable proof without asset transfers.
Timestamped records for divorce, estate planning, or immigration.
Verify accredited investor status and fund minimums at scale.
Users prove ownership. Institutions get verification. No custody compromise.
Prove wallet ownership when institutions need it. Your keys stay with you. You control who sees what, and for how long.
Add wallet verification to existing flows. REST API, webhooks, hosted links. No custody required.
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.

Self-custody wallets do not become regulated institutions. But as FATF, MiCA, DAC8, and CARF raise the standard for crypto evidence, institutions increasingly need defensible proof of wallet control, attribution, crypto proof of funds, and scoped transaction evidence.
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.
Crypto-backed, conforming mortgages are moving into view. The limiting factor is no longer whether crypto belongs in mortgage finance, but whether self-custodied assets can be evidenced to underwriting, audit, and secondary-market standards.
