title: Bid collecting adjustments

---

According to the document https://www.notion.so/MEV-monitor-updates-relate-to-bid-adjustments-6b0df90a68c24edca4ed970c5c7c5457 consider the ways how to reflect adjusted bids in [fee-monitoring](https://fees-monitoring.lido.fi/) and `MEV Monitoring DB` Grafana dashboard.

# MEV Monitoring DB

Add new fields into section "Proposals. Lido blocks" at table "Proposed blocks by Lido validators (limit of 100 slots)":
- Bid value
- Adjusted Bid value

As an alternative, new section "Proposals. Bids" might be created with a table contains the following fields:
- slot
- relay
- builder
- builder submitted value
- relay adjusted value
- proposed value

**Estimation: 2-3d**

# Fee monitoring

Add new column to table `Slots Value` on `Node Operator` page at `Delta balance` tab:
  - `relay`, when hover over the label, display a tooltip with: `builder`, `builder submitted value`, `relay adjusted value`, `proposed value`

**Estimation: 2d**

# Changes at code level
## Relay monitoring
- modify `sync-submitted-payload` job and table to collect data from endpoint https://relay.ultrasound.money/ultrasound/v1/data/adjustments?slot=8436599
- modify endpoint `/v1/relays/signed-bids/:block` to reflect adjustments in response.


## Mev monitoring
- add new columns to `slot_storage` table
- modify `PayloadService` to collect new data from relay-monitoring
