Delegator

Delegators are network participants who delegate (i.e., "stake") GRT to one or more Indexers. Delegators contribute to securing the network without running a Graph Node themselves.
By delegating to an Indexer, Delegators earn a portion of the Indexer's query fees and rewards. The amount of queries an Indexer can process depends on the Indexer's own (and delegated) stake and the price the Indexer charges for each query, so the more stake that is allocated to an Indexer, the more potential queries they can process.

Delegator Guide

This guide will explain how to be an effective Delegator in the Graph Network. Delegators share earnings of the protocol alongside all Indexers based on their delegated stake. A Delegator must use their best judgment to choose Indexers based on multiple factors. Please note this guide will not go over steps such as setting up Metamask properly, as that information is widely available on the internet. There are three sections in this guide:
  • The risks of delegating tokens in The Graph Network
  • How to calculate expected returns as a Delegator
  • A video guide showing the steps to delegate in the Graph Network UI

Delegation Risks

Listed below are the main risks of being a Delegator in the protocol.

The delegation tax

Delegators cannot be slashed for bad behavior, but there is a tax on Delegators to disincentivize poor decision-making that could harm the integrity of the network.
It is important to understand that every time you delegate, you will be charged 0.5%. This means if you are delegating 1000 GRT, you will automatically burn 5 GRT.
This means that to be safe, a Delegator should calculate what their return will be by delegating to an Indexer. For example, a Delegator might calculate how many days it will take before they have earned back the 0.5% tax on their delegation.

The delegation unbonding period

Whenever a Delegator wants to undelegate, their tokens are subject to a 28-day unbonding period. This means they cannot transfer their tokens, or earn any rewards for 28 days.
One thing to consider as well is choosing an Indexer wisely. If you choose an Indexer who was not trustworthy, or not doing a good job, you will want to undelegate, which means you will be losing a lot of opportunities to earn rewards, which can be just as bad as burning GRT.
Note the 0.5% fee in the Delegation UI, as well as the 28 day unbonding period.

Choosing a trustworthy Indexer with a fair reward payout for Delegators

This is an important part to understand. First let's discuss three very important values, which are the Delegation Parameters.
Indexing Reward Cut - The indexing reward cut is the portion of the rewards that the Indexer will keep for themselves. That means if it is set to 100%, as a Delegator you will get 0 indexing rewards. If you see 80% in the UI, that means as a Delegator, you will receive 20%. An important note - at the beginning of the network, Indexing Rewards will account for the majority of the rewards.
The top Indexer is giving Delegators 90% of the rewards. The middle one is giving Delegators 20%. The bottom one is giving Delegators ~83%.
  • Query Fee Cut - This works exactly like the Indexing Reward Cut. However, this is specifically for returns on the query fees the Indexer collects. It should be noted that at the start of the network, returns from query fees will be very small compared to the indexing reward. It is recommended to pay attention to the network to determine when the query fees in the network will start to be more significant.
As you can see, there is a lot of thought that must go into choosing the right Indexer. This is why we highly recommend you explore The Graph Discord to determine who the Indexers are with the best social reputation, and technical reputation, to reward Delegators consistently. Many of the Indexers are very active in Discord and will be happy to answer your questions. Many of them have been Indexing for months in the testnet, and are doing their best to help Delegators earn a good return, as it improves the health and success of the network.

Calculating Delegators expected return

A Delegator has to consider a lot of factors when determining the return. These include:
  • A technical Delegator can also look at the Indexer's ability to use the Delegated tokens available to them. If an Indexer is not allocating all the tokens available, they are not earning the maximum profit they could be for themselves or their Delegators.
  • Right now in the network an Indexer can choose to close an allocation and collect rewards anytime between 1 and 28 days. So it is possible that an Indexer has a lot of rewards they have not collected yet, and thus, their total rewards are low. This should be taken into consideration in the early days.

Considering the query fee cut and indexing fee cut

As described in the above sections, you should choose an Indexer that is transparent and honest about setting their Query Fee Cut and Indexing Fee Cuts. A Delegator should also look at the Parameters Cooldown time to see how much of a time buffer they have. After that is done, it is fairly simple to calculate the amount of rewards the Delegators are getting. The formula is:

Considering the Indexer's delegation pool

Another thing a Delegator has to consider is what proportion of the Delegation Pool they own. All delegation rewards are shared evenly, with a simple rebalancing of the pool determined by the amount the Delegator has deposited into the pool. This gives the Delegator a share of the pool:
Share formula
Using this formula, we can see that it is actually possible for an Indexer who is offering only 20% to Delegators, to actually be giving Delegators an even better reward than an Indexer who is giving 90% to Delegators.
A Delegator can therefore do the math to determine that the Indexer offering 20% to Delegators, is offering a better return.

Considering the delegation capacity

Another thing to consider is the delegation capacity. Currently, the Delegation Ratio is set to 16. This means that if an Indexer has staked 1,000,000 GRT, their Delegation Capacity is 16,000,000 GRT of Delegated tokens that they can use in the protocol. Any delegated tokens over this amount will dilute all the Delegator rewards.
Imagine an Indexer has 100,000,000 GRT delegated to them, and their capacity is only 16,000,000 GRT. This means effectively, 84,000,000 GRT tokens are not being used to earn tokens. And all the Delegators, and the Indexer, are earning way less rewards than they could be.
Therefore a Delegator should always consider the Delegation Capacity of an Indexer, and factor it into their decision making.

Delegator FAQs and Bugs

MetaMask "Pending Transaction" Bug

When I try to delegate my transaction in MetaMask appears as "Pending" or "Queued" for longer than expected. What should I do?
At times, attempts to delegate to indexers via MetaMask can fail and result in prolonged periods of "Pending" or "Queued" transaction attempts. For example, a user may attempt to delegate with an insufficient gas fee relative to the current prices, resulting in the transaction attempt displaying as "Pending" in their MetaMask wallet for 15+ minutes. When this occurs, subsequent transactions can be attempted by a user, but these will not be processed until the initial transaction is mined, as transactions for an address must be processed in order. In such cases, these transactions can be cancelled in MetaMask, but the transactions attempts will accrue gas fees without any guarantee that subsequent attempts will be successful. A simpler resolution to this bug is restarting the browsesr (e.g., using "abort:restart" in the address bar), which will cancel all previous attempts without gas being subtracted from the wallet. Several users that have encountered this issue and have reported successful transactions after restarting their browser and attempting to delegate.
