Coinfloor is a custodian of client bitcoins and we believe that we must set the industry standard for transparency and regular audits. Without proper public accountability, the industry will not be able to grow and mature. This is why we are committed to releasing a Provable Solvency Report every month. Coinfloor is proud to have the longest standing track record among bitcoin exchanges in regards to auditing.

Today we are publishing our 62nd monthly Provable Solvency Report with step-by-step validation instructions for your convenience.

As of today, Coinfloor holds a total of 4,121.1897 XBT on behalf of our clients. You are invited to verify that your held bitcoins are included in this balance by following the instructions below.

What does the Provable Solvency Report include?

We started out by creating an obfuscated report of all current client balances (the Solvency Report) and then generated a SHA-256 hash of this report.

We then created a bitcoin transaction to ourselves, that includes all currently held client bitcoins, for a value of 4,170.6431 XBT. The output of the script also includes the OP_RETURN of the SHA-256 hash of the report, proving that at the time of making the solvency report, Coinfloor held all of our clients’ XBT funds. You can verify the amount and details of the transaction on the blockchain.

Your API authentication cookie:
You will find it in My Account > Dashboard in the Coinfloor signed in view, in the API section (visible only for fully verified accounts).

Instructions for Validating Solvency Report:

1. Open the Provable Solvency Report file:

https://s3-eu-west-1.amazonaws.com/provablesolvency/solvency_20190529.txt

2. Go to

https://passwordsgenerator.net/sha256-hash-generator/ or to your SHA256sum calculating application.

Copy the entire contents of the solvency report (including any leading or trailing spaces or blank lines) into the SHA-256 generator and calculate the SHA-256 hash of the report.

3. Go to

https://explorer.bitcoin.com/btc/tx/c91158b6dad7794072d2a6d06ca3e8496d81e564ad2d1c8850ae582760d1fe07

Click on the `SHOW ADVANCED` switch to view the OP_RETURN, where you will find the hash generated in the previous step matches the hash in the OP_RETURN output script of the transaction that includes all customer bitcoins.

Instructions for finding your account balance within the Solvency Report:

1. Go to

your local SHA1sum application

to calculate the SHA-1 digest of a message consisting of the timestamp shown at the top of the Solvency Report (1559120352) and your API authentication cookie.

Example (Linux):

    timestamp: 1559120352

    API authentication cookie (API Key): 9BTa7M0Z/Mrk6tFMJwEkTV3BQek=

    command: echo -n ‘15591203529BTa7M0Z/Mrk6tFMJwEkTV3BQek=’ | sha1sum

(the command may differ depending on the SHA1sum application used)

2. Find the resulting hash in the solvency report. Your balance is shown on that line in satoshi units. 1 bitcoin = 100 000 000 satoshis. For your convenience, here is a link to a bitcoin unit converter:

We believe that this approach is the best way to achieve maximum accountability whilst retaining privacy for our clients. We welcome your feedback and hope that in time, other exchanges will also help safeguard client funds by providing proof of solvency reports to their users on a regular basis.

Thank you for your trust,

Coinfloor Team

Our partnership with Enumis will ensure that this will no longer be an issue.

With our joint pedigree and market expertise in the cryptocurrency and financial services spaces, we hope that this offering designed by members of the crypto community for the community will help the community of crypto businesses overcome their financial limitations and drive the crypto economy forward.”

Who is this service for?

The service is aimed at businesses operating in the crypto space and has been created specifically to meet the demand for a trustworthy domestic fiat current account on the Faster Payments network.
