Introducing Wallet Proof Links: Verifiable Proof of Funds for Self-Custodied Crypto

Crypto proof of funds still depends too heavily on screenshots.

A borrower sends a wallet balance image to a lender. A client forwards a PDF export to a broker. An investor copies addresses into an email thread. A compliance team receives a bundle of files and has to decide whether the evidence is current, complete, and actually connected to the person presenting it.

These workflows are familiar, but they are weak.

Screenshots can be outdated the moment they are captured. PDFs and exchange exports may show balances, but they often fail to prove control over self-custodied wallets. A copied address can be inspected on-chain, but visibility is not ownership. And when evidence is scattered across messages, files, and manual explanations, it becomes difficult to audit later.

Today we are introducing Wallet Proof Links, a new Accredifi feature that lets users generate secure, shareable proof-of-funds pages for self-custodied crypto wallets.

Wallet Proof Links are built around a simple idea: institutions do not necessarily need custody of crypto assets. They need verifiable evidence.

The Problem With Screenshot-Based Proof of Funds

Traditional proof-of-funds workflows were built around intermediated finance.

If assets are held at a bank, broker, or exchange, a reviewer can often ask for a statement. The statement is not perfect, but it comes from an institution of record. It usually contains names, dates, account references, and balances in a format financial teams already understand.

Self-custodied crypto works differently.

A Bitcoin or Ethereum wallet may hold significant assets without any bank, broker, or exchange sitting between the user and the funds. That is one of the strengths of self-custody, but it creates a verification problem for financial workflows that still expect institution-issued evidence.

When no custodian can issue a statement, the market has often fallen back to weaker substitutes:

screenshots of wallet interfaces
manually exported transaction files
copied wallet addresses
exchange reports that do not cover self-custodied assets
informal attestations sent over email

Each of these can be useful context. None of them is a strong proof-of-funds workflow on its own.

The missing piece is not just balance visibility. It is a defensible connection between the user, the wallet, the holdings, and the point in time when the proof was created.

Why Displayed Balances Are Not Enough

A wallet balance shown on a screen is not the same thing as verified financial evidence.

For a lender, broker, underwriter, compliance analyst, or counterparty, the core questions are more precise:

Does this person control the wallet being presented?
What assets were visible in that wallet when the proof was created?
Is there a reviewable record that can be returned to later?
Was the user able to provide this evidence without moving funds or exposing keys?

Screenshots answer those questions poorly.

They show what an interface appeared to show, but they do not establish wallet control. They rarely preserve enough technical context for later review. They can be separated from the workflow that produced them. And they place too much interpretive burden on the reviewer.

That is why crypto proof of funds needs to move from visual evidence to structured evidence.

Cryptographic Wallet Verification

Wallet Proof Links use cryptographic message signing to verify wallet control.

Instead of asking a user to move funds or disclose private keys, Accredifi asks the user to sign a message from the wallet they want to prove. A valid signature demonstrates that the user controls the private key associated with that wallet address at the time the proof is created.

This is an important distinction.

The proof is tied to cryptographic wallet ownership, not merely to a balance displayed in an app. The balance matters, but it becomes more useful when it is connected to verified control of the wallet that holds it.

For users, signing a message is non-custodial. Funds do not move. Private keys are not shared. The wallet remains under the user's control.

For reviewers, the result is stronger evidence. The proof is not just "someone sent a screenshot of a wallet." It is "this wallet was controlled through a signed message, and these holdings were recorded at the time of proof creation."

What Wallet Proof Links Do

A Wallet Proof Link is a secure, shareable proof-of-funds page for a self-custodied crypto wallet.

The user creates a proof by verifying wallet control through message signing. Accredifi then records the relevant wallet holdings at that point in time and makes the proof available through a dedicated link.

That link can be shared with the teams or counterparties who need to review the evidence, including:

lenders
mortgage brokers
underwriters
compliance teams
OTC desks
investor diligence teams
auditors
other financial counterparties

The goal is to make proof of funds easier to share without reducing it to an image file or forcing users into custody transfer.

Wallet Proof Links are designed to be:

Non-custodial: users never transfer assets to Accredifi or hand over private keys
Cryptographically verifiable: wallet control is confirmed through signed messages
Shareable: proofs can be accessed through a dedicated link
Time-bound: holdings are recorded at the point the proof is created
Institution-ready: evidence is structured for onboarding, underwriting, lending, compliance, and review workflows

This makes the proof reusable in a way that screenshots are not. A link can be reviewed, shared with the appropriate party, and preserved as part of a file or workflow with clearer context around ownership and timing.

Non-Custodial by Design

Wallet Proof Links are built for self-custody.

Users stay in control of their assets throughout the process. They do not need to transfer funds to an exchange, escrow wallet, lender, or third-party custodian just to prove that assets exist. They do not need to reveal seed phrases or private keys. They do not need to compromise their custody setup for the sake of documentation.

That matters because many proof-of-assets workflows quietly create unnecessary custody pressure. A user may be asked to move assets to a platform because the platform can issue a statement, not because custody transfer is actually needed for the underlying decision.

Accredifi's view is different: when the goal is verification, custody is not always required.

In many workflows, the institution needs reliable evidence of wallet ownership and holdings. A cryptographic proof can satisfy that need without changing who controls the assets.

Built for Bitcoin and Ethereum Wallets

Wallet Proof Links support both Bitcoin and Ethereum wallets.

They can be generated from common self-custody setups, including software wallets, browser wallets, and supported hardware wallets.

That flexibility is important because self-custody is not one workflow. Some users manage assets from mobile or desktop software wallets. Others use browser wallets for Ethereum activity. Many higher-value holders use hardware wallets as part of a more controlled key management process.

Proof-of-funds infrastructure should work with those custody choices, not push users into a less appropriate setup simply because the verification process is easier for the reviewer.

Better Evidence for Institutional Crypto Workflows

Wallet Proof Links are relevant anywhere a third party needs confidence in self-custodied assets without taking control of them.

Common use cases include:

crypto-backed lending
mortgage and affordability checks
wealth verification
OTC onboarding
investor due diligence
compliance and audit workflows

Each workflow has its own review standard, but the evidence problem is similar. The reviewer needs to understand whether the assets exist, whether the user controls the wallet, and when that evidence was created.

Wallet Proof Links give those workflows a more consistent object to review: a time-scoped proof tied to wallet ownership and holdings.

That is a better fit for institutional processes than a folder of screenshots. It is also a better fit for users who want to prove assets without giving up the protections of self-custody.

From Static Files to Reusable Proof

Financial verification is moving toward more portable, structured, and reusable evidence.

In crypto, that shift is especially important. The underlying assets are already verifiable in ways that traditional financial assets are not, but the workflows around them are still too manual. Reviewers should not have to infer wallet control from screenshots. Users should not have to assemble bespoke evidence packages every time a lender, broker, or compliance team asks for proof.

Wallet Proof Links are a step toward a more practical model: cryptographic proof of wallet control, holdings captured at a point in time, and a shareable record that can be used in real financial workflows.

This is part of a broader movement toward self-custodied financial infrastructure. Users can hold assets directly. Institutions can still perform responsible verification. The connective layer is not custody by default; it is structured, auditable evidence.

A New Primitive for Proof of Funds

Proof of funds should be more than a screenshot.

For self-custodied crypto, it should establish wallet ownership, record holdings at a defined moment, preserve context for review, and allow the user to remain in control of their assets.

Wallet Proof Links are designed for that standard.

They give crypto-native users a safer way to share proof of funds, and they give financial institutions a more defensible record to review. The result is not a replacement for every diligence process, but a stronger foundation for the part of the process that asks: does this user control these assets, and what was visible at the time of proof?

That foundation matters as self-custodied assets become part of more lending, underwriting, wealth, compliance, and investment workflows.

Reusable, auditable, cryptographic proof-of-funds infrastructure is becoming a necessary layer for self-custodied finance. Wallet Proof Links are Accredifi's next step in building it.
