New Discord Announcement from THORChain Devs #🚨thornode-mainnet

## Mimir Vote Request: `STREAMINGLIMITSWAPMAXAGE = 5256000`

Requesting **3 node operators** to cast an operational Mimir vote.

| Field | Value |
|---|---|
| **Key** | `STREAMINGLIMITSWAPMAXAGE` |
| **New value** | `5256000` (~1 year) |
| **Current default** | `43200` (~3 days) |
| **Votes needed** | 3 (`OperationalVotesMin`) |

### What it does

Raises the max lifetime of a limit swap from ~3 days to ~1 year. Long-dated limit orders are a frequently requested feature, and a 3-day ceiling is too short to be useful for most traders.

### Why it's safe now

The previous blocker was performance: `processExpiredLimitSwaps` scanned every height from `currentHeight - maxAge` forward on each block, so a 1-year TTL meant millions of KVStore lookups per block.

That was fixed — expiry entries are stored at their exact expiry height, so the handler now does a **single lookup for the current block**. Cost per block is constant regardless of how large this value is.

### No admin key or hard fork required

`StreamingLimitSwapMaxAge` is in the operational-mimir list, so three matching node votes activate it.

### How to vote

From your node-launcher directory:

```bash
make mimir

Enter when prompted:

- Key: STREAMINGLIMITSWAPMAXAGE
- Value: 5256000
```
