Edgeware FAQs

How is Edgeware's reward rate* determined?

Edgeware’s native rate of participatory rewards is determined by the staking rate of the protocol, capping out at 20% when 80% of the protocol’s tokens are staked.

An inflation model calculator can be found here.

* Reward rates published by Coinbase Cloud are estimates based on publicly available information from third-party sources. Coinbase Cloud has not verified and does not guarantee the accuracy of this information. Reward rates on some protocols may vary based on the amount staked and/or other variables, including validator performance, so you should not rely on the accuracy of any reward rate ranges we publish, which are intended to provide an estimate. The actual rate of rewards earned may vary substantially and may change over time and Coinbase Cloud does not guarantee that you will receive any staking rewards. Staked assets may be subject to slashing penalties and risk of loss is possible, including up to the full loss of principal.


What are the risks associated with delegating?

If a validator doesn't follow protocol rules, Edgeware slashes their bonded tokens as well as slasing the EDG delegated to them. If your EDG are delegated to a validator that gets slashed, you run the risk of losing a percentage of your delegated tokens.

  • Double signing: If someone reports on chain A that a validator signed two blocks at the same height on chain A and chain B, the validator will get slashed on chain A.
  • Unavailability: A validator is considered unresponsive if it produces no blocks for an epoch (about 60 minutes) and if it also fails to send an “I’m online” message. However, no penalty is enacted for being offline if less than 10% of all validators are offline.

Why should I select all Coinbase Cloud validator addresses to nominate when staking?

When you nominate multiple validators, each era the protocol will automatically allocate your stake to the validator(s) you have nominated which have also been selected to participate in the active set — and to earn rewards in exchange for doing so.

Because of this ability within Edgeware, your performance will be optimized by nominating all of the validators in the list, as the more validators you nominate, the greater the likelihood that at least one of those validators will be selected to earn rewards each era.

You can learn more about Active and Inactive Nominations, and how this allocation works, in Polkadot’s documentation, which inform's Edgeware's system as well.

Does everyone who delegates to the validator receive rewards?

In Edgeware, only the 64 largest delegators to a validator will receive rewards. You can see the list of all delegators on Coinbase Cloud's validators in the Polkadot UI when searching for “Bison Trails.”

How does Coinbase Cloud's service fee work?

Coinbase Cloud charges a percentage service fee on all rewards earned by tokens delegated to our Edgeware validator. The service fee is paid to Coinbase Cloud automatically by the protocol. You can withdraw your rewards from the protocol directly.
