`info` endpoint `delegatorRewards` type does not attribute reward to a specific validator

[karen-cb]

Summary

This is a feature request for the [delegatorRewards type under the /info API endpoint](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/api/info-endpoint#query-a-users-staking-rewards).

delegatorRewards returns one entry per reward credit: {time, source, totalAmount}. source is "delegation" or "commission", but there is no validator field.

For a delegator staking to more than one validator, there is no way to determine which validator a given reward is attributed to. Since HYPE auto-compounds — reward amounts are added directly into the delegated balance, this means the exact, reward-inclusive per-validator staked balance cannot be reconstructed for any delegator that staked to multiple validator from any available field.

Reproduction

curl -s -X POST https://api.hyperliquid.xyz/info -H "Content-Type: application/json" \
  -d '{"type":"delegatorRewards","user":"0x393d0b87ed38fc779fd9611144ae649ba6082109"}'

Real response shape, from a real 14-validator delegator:

[{"time":1735560015000,"source":"delegation","totalAmount":"0.59429787"}, ...]

No validator key in the entry — confirmed against this real multi-validator address and a simpler single-validator address.

Why this matters

We have a reporting need for per-delegation staked balances for a multi-validator delegator (not just an account-wide aggregate).

Ask

• Add a validator field to each delegatorRewards entry, so the true per-validator amount is directly reported.
