New Discord Announcement from THORChain Devs #🚨thornode-mainnet

**LP & Churn Paused**

Devs have received a responsible disclosure as part of the ongoing bug bounty program. While this potential issue is verified and reproduced, nodes have proactively paused:
- Limit Orders
- LP Actions (Add / Withdraw)
- Churn

3.15 will be released to `mainnet` next week (21 Jan 2026). If a patch is necessary, the above will remain paused and a fix will be included in the 3.15 release. @everyone

**BCH Trading Paused**

Nodes have paused BCH trading after observing an issue which caused BCH outbounds to P2SH to be sent to an incorrect outbound address. The BCH chain trading was paused out of an abundance of caution to protect any users who may be swapping to a Bitcoin Cash P2SH address. This will also be addressed in the 3.15 upgrade scheduled for next week.

## XRP Config

There is an update required to the XRP config to continue syncing blocks. If you have not already done so, please `make pull` and `make install` to apply. Once the XRP daemon is in ready state, it is likely you will need to force the scanner height forward past the pruned heights by setting `BIFROST_CHAINS_XRP_BLOCK_SCANNER_START_BLOCK_HEIGHT=101672000` (or a later block depending on when you apply) in your Bifrost environment. Once 80% of the network is back to tip it should be safe to resume XRP.

## THORNODE ❗️MAINNET❗️UPDATE 3.15.0
https://gitlab.com/thorchain/thornode/-/releases/v3.15.0

NETWORK: MAINNET
TYPE: Non-coordinated
URGENCY: 20h

The upgrade proposal has passed. Please install to schedule the upgrade at the proposed height. Nodes will automatically update to the new image at the scheduled height, and the node version for active validators will be automatically set at that time. All non-active validators must run `make set-version` after the upgrade height to be eligible for the subsequent churn. Churn will be re-enabled after the upgrade.

```
make pull
make install
```

Please note that this build contains private security patches, so the tagged release on Gitlab does not contain all consensus changes and the release image must be used. This release build will not be locally reproducible, but the build hash has been verified by multiple devs and the security team.

### Solana Launch Preparation

Solana has been live on `stagenet` for 6 weeks without issue. The team plans to proceed with `mainnet` enabling on February 4 around midday US time. If there are no operational issues or fixes that take priority, the plan will be as follows:

1. Nodes should prepare a Solana RPC, whether self hosted (nothing is provided in `node-launcher` due to hardware requirements) or with a provider of choice.
2. Churning will be halted on Sunday February 1 to ensure the churn adding Solana to vaults occurs midweek.
3. Nodes will be instructed to enable Solana scanners approximately 24h before the intended churn on February 4.

Since the majority of nodes will find it cost prohibitive to run their own Solana nodes, the network will be leveraging external providers for the chain. In order to prevent a single provider from being able to eclipse attack or cause outage, nodes should distribute across a variety of providers. Please `make mimir` and set `SOL-RPC-PROVIDER` to one of the following values, indicating which provider you plan to use. If your provider already has a 20% share of nodes, please choose a different provider. If you are using a provider not in this list, please `make relay` it and we will add a corresponding voting key.

```
1 => Self Hosted
2 => Liquify (reach out to Andy or Isaac)
3 => QuickNode
4 => Alchemy
5 => Chainstack
6 => Ankr
7 => Blockdaemon
8 => Helius
```

It is a prerequisite for launch that 80% of nodes have designated an RPC provider via the mimir vote, and no single provider is above 20% dominance. If that condition is unmet by February 1, the timeline will be delayed.

New Discord Announcement from THORChain Devs #🚨thornode-mainnet

## THORNODE ❗️MAINNET❗️UPDATE 3.15.1 (Bifrost Only)
https://gitlab.com/thorchain/thornode/-/releases/v3.15.1

NETWORK: MAINNET
TYPE: Non-coordianted
URGENCY: ASAP

This is a Bifrost-only patch release containing a fix for a bug preventing observations of outbounds in the same block of a cancelled stuck transaction. Please `make pull` and `make install` to apply.

There are also a number of dropped mempool outbounds that require a quorum of the culprit vault to perform manual steps to clear the outbounds and complete churn. This has been historically infrequent, but has occurred a few times in the past months - the team is still discussing the safest path to handle this automatically in a future release.

If you are a node in the set above, please perform the following:
```
make debug
# select cosmosfullnode
# select thornode
# select bifrost
rm -rf /var/data/bifrost/observer/BTC/
# exit shell and ensure bifrost starts back up
```

New Discord Announcement from THORChain Devs #🚨thornode-mainnet

## THORNODE ❗️MAINNET❗️UPDATE 3.15.2 (Bifrost Only)
https://gitlab.com/thorchain/thornode/-/releases/v3.15.2

NETWORK: MAINNET
TYPE: Non-coordianted
URGENCY: ASAP

This is a Bifrost-only patch release containing a few fixes for races in the TRON client signing that are causing stuck outbounds. Please `make pull` and `make install` to apply. We are hopeful these fixes will clear the TRON outbound queue once adopted by a quorum of all vaults. Once all stuck outbounds have cleared, it should be safe to resume TRON trading.

## THORNODE ❗️MAINNET❗️UPDATE 3.15.3 (Bifrost Only)❗️ENABLE SOLANA
https://gitlab.com/thorchain/thornode/-/releases/v3.15.3

NETWORK: MAINNET
TYPE: Non-coordianted
URGENCY: 24h

This is a Bifrost-only patch release containing a final Solana fix and enabling the scanner by default. Please `make pull`, set the Bifrost environment variable `BIFROST_CHAINS_SOL_RPC_HOST` to your RPC provider, then `make install` to apply.

We will wait 24 hours from the time of this message. Then once a quorum of all vaults are scanning Solana at tip, we will unhalt churning and proceed to keygen Solana vaults.
