About Sentinel

Sentinel runs validators on proof-of-stake networks and lets people share in what they earn. You deposit a dollar stablecoin, choose a pool for a network, and are paid a share of what that pool pays out. We hold the funds for you, which makes this a custodial service.

What we do

Pools, for individuals. 145 networks are listed, each with its own commission and unbonding period. A pool pays a daily rate that we set and review, below what its network is expected to earn, so good days build a reserve for lean ones. That rate is not a guarantee.

Validator operations, for institutions. Infrastructure, monitoring, upgrades and key management, on terms agreed per engagement. Validator services

We publish the address of every validator our pools delegate to: 10 so far, on the transparency page, so you can check them on a public block explorer. Transparency

Where we are from

Sentinel is a company registered in the United Kingdom, open to customers in many countries.

Being registered in the UK is not the same as being protected like a UK bank. Your balance with us is not a bank deposit and is not covered by the Financial Services Compensation Scheme (FSCS). Nothing we hold is insured, and our platform has not been audited by an outside firm.

How we make money

Mainly from a commission on what our validators earn. We do not charge to deposit, delegate or undelegate.

Commission
5% to 9% of the daily reward
Our main revenue. A share of each pool’s daily reward, set per pool and shown before you delegate. The daily reward we show is what you receive, after it. It is never taken from the amount you put in.
Infrastructure fund
11% to 13% of the daily reward
A second share of rewards that pays for servers, monitoring and the validators we launch on new networks. It is kept by Sentinel for that purpose, not paid to delegators.
Withdrawal fee
8% per withdrawal
Taken out of each withdrawal you make to an outside wallet. You see the fee and what will arrive before you confirm.
Validator services
Teams that want us to run validators for them pay terms agreed per engagement, not the retail pool rates.

On a day a pool earns less than it pays out, we give up our commission and the fund’s share first. Anything still short comes from the pool’s reserve, then from money the company has put aside for it. If that runs out, the day is not paid: it is never paid from another customer’s money.

Team rewards are paid out of our commission, never from the person who was invited.

The risks

  • We hold your money. Getting it back depends on Sentinel continuing to operate, stay solvent and act honestly.
  • Rewards are not guaranteed. The daily rate can change, and the reserve behind it is finite.
  • What you delegate is at risk. A network can penalise a validator for downtime or misbehaviour, and the loss is shared by everyone in that pool.
  • Your funds are locked while unbonding. Once you undelegate, the amount you delegated earns nothing and cannot be withdrawn until the network’s unbonding period ends: up to 30 days, depending on the network.
  • We are early. We do not yet have a track record to show you, and the rules for custodial crypto services may change where you live.
