Prove solvency.
Reveal nothing.

Starkproof lets any Bitcoin (or other digital asset) custodian cryptographically prove their reserves exceed liabilities — without exposing wallet addresses, exact balances, or customer data.

Process

How it works

Four steps from registration to live solvency status

Connect and Register

Connect your Braavos wallet to Starknet Sepolia. Enter your exchange name — your entity identity is derived cryptographically from your name and wallet address.

Run the ZK Circuit

Add your Bitcoin (or other token) cold wallet addresses. Upload your customer liability CSV. The zero-knowledge circuit runs entirely in your browser — your balances and customer data never leave your machine.

Submit to Starknet

Sign one transaction. Your proof commitment and public inputs are stored permanently on Starknet. Anyone can verify your solvency without learning your balances.

Renew Every 28 Days

Proofs expire after 28 days. Your dashboard shows a countdown and alerts you before expiry. Renewal takes under two minutes for returning operators.

Security Model

What the protocol guarantees

The zero-knowledge circuit makes mathematical guarantees that no amount of trust or auditing can match. These properties hold regardless of whether you trust this frontend, the Starkproof team, or the exchange itself.

Independent Verification Tool

No balance exposed

Wallet addresses and exact holdings stay in your browser

No customer data on-chain

Only the Merkle root commitment is published

Mathematically unforgeable

An insolvent entity cannot produce a valid proof

Permanent record

Starknet stores every proof submission immutably

Classification

Reserve ratio bands

The circuit classifies proof results into four bands. The band is public — exact reserves are not.

Band 0

< 100%

Insolvent

Circuit fails. No proof possible.

Band 1

100 – 110%

Solvent

Minimum viable. Warning threshold.

Band 2

110 – 120%

Comfortable

Acceptable buffer.

Band 3

>= 120%

Strong

Overcollateralized. Preferred.
