Staking Pool Questionnaire Answers

Stakefish was provided an initial questionnaire by the EDDC to provide further insights into how Stakefish works and to evaluate their safety as a Staking Pool Service. Please see below for the EDDC questions and Stakefish answers.

What country is your business based out of?


Are you confident that you are adhering to all of the necessary regulations for the jurisdiction you are in?


How much control do you have over users’ funds? – Do you hold 0, 1, or 2 keys?

We only hold the signing keys.

Do you have any insurance in case funds are lost?

No. We will refund any fees in the event that slashing (that has not been caused by client or network failure or bugs) has occurred.

What is your company’s history in the cryptocurrency space?

Our sister company, f2pool, was founded in 2013 and is the longest running mining pool. stakefish has been running validators for blockchain projects from 2018.

Who are your team members, and what are their academic and professional backgrounds?

Our key team members are:

– Wang Chun, who has been running f2pool, a key infrastructure project of the PoW space, from 2013 without any major hiccups

– Cristian Lucera, who has two decades of experience managing infrastructure and security for enterprises

– Dení Sukhonina, who has 14 years of experience building performance-critical server-side applications and services and has consistently contributed to open source projects

If you are using smart contracts, have they been audited, by whom?

Yes, our Batch Deposit Contract has been audited by Runtime Verification. The link to the audit report is available here:

Describe your staking setup. – Do you have your own servers, if no, which hosting provider are you using? Which client(s) are you using? How many nodes are you using? Do you have some sort of redundancy built-in? etc…

We will be using multiple hosting providers (AWS, Google Cloud, Azure and DigitalOcean) across multiple regions (at a minimum one in Asia, Europe and Americas). We have built our platform primarily using Prysm and Lighthouse with plans to integrate additional clients after the Beacon Chain has stabilized. We plan to have at least 10 nodes with additional ones deployed depending on how many validators we manage.

We can quickly and programmatically spin up validators in the rare event one of our existing nodes stop functioning properly. Based on our experiences running validators on other Proof of Stake networks, we prioritize double-signing protections and real-time monitoring & incident management system over redundancy measures. We have applied the same level of discipline on running infrastructure on other networks to our Beacon Chain validators.

Who is invested in your business, is there venture capital, is there a token? If there is a token, what is it used for?

Stakefish is fully self-funded by Wang Chun. We do not have any tokens and do not have any plans to issue one for the foreseeable future.

How much are you charging for your staking services?

A one-time flat fee of 0.1 ETH until withdrawals are enabled.
