Summary

Terra Launched, Chain halt and restart, Hard Fork and CosmosSDK upgrade, Trading Halts and resumption, Pooled Nodes now activated — a lot has happened in a couple of weeks. The community of THORChain, Devs and Node Operators shone. Three important Mainnet milestones were achieved, TVL cross 1 billion USD and trading volume hit an all time high, along with several network and community updates.

Terra Launched and Soft Cap Removed

After many months of effort by many THORChads, Terra integration occurred on the 25th of March. This enables the combination of the only decentralised exchange with the only decentralised stablecoin.

See full details and how-tos in this Terra Launch Article.

The Soft Cap was permanently disabled, removing the last guardrail for Chaosnet. For wallet backward compatibility the Softcap has been set to the 500m, the max RUNE supply, and later it will be set to the total bonded RUNE, which is the hard cap. The hard cap is now the only liquidity limit on the system, and it is extremely unlikely the hardcap will ever be reached due to THORChain’s Incentive Pendulum.

Pooled THORNodes Went Live with a Warning

This important feature allows a group of up to six friends to team together to come up with enough $RUNE capital to run a node. This effectively means that more people can run nodes which will further decentralise the network while also deepening the BOND on the network, which allows the network to support more liquidity and a higher TVL. THORChain Docs have been updated with more information.

BUT! The community should take caution to avoid scams. Anyone who is running the node effectively has access to the Yggdrasil funds of that node, and therefore has an ability to rug pull you.

DO NOT send your $RUNE into the node of a person you don’t know who they are and don’t fully trust. Do not contribute to the node of a random person on Twitter, telegram, discord etc (even if that person is any member of the core devs or mods/admins, as names can be spoofed).

Please protect your RUNE with the utmost caution and paranoia!

Unscheduled Chain Halt

A consensus failure caused an unscheduled halt of the chain. The bug was not related to any recent code change, as was thought in the early investigation. The source of the bug has been there since early June at the latest, which means it was a part of all audits before/after summer exploits, THORGames, informal audits and testing. From discovery to resumption took less than 6 hours.

Trading Halts for ETH and TERRA

Trading was halted for the Terra and ETH chains. A bug was found where amounts are not rounded properly for any token with fewer than 8 decimals. The fix has been identified, and the patch has been merged in release 1.84.0. Trading has now resumed.

Hardfork and Cosmos SDK Completed

The Hardfork and Cosmos SDK upgrade on Stagenet and Chaosnet occurred. The chain ID for Chaosnet is: thorchain-mainnet-v1. Node Mimirs were overlooked in the genesis file and were dropped, which meant nodes needed to cast their re-vote.

Ensure you update any software such as desktop apps or browser extensions.

Max Reward Ratio for Validators Changed

Max Reward Ratio for Validators was changed to from 1 to 3 via node voting, which changes how much rewards Node Operators can earn. Before, each node earned the same reward (minus slash points), irrespective of the bond size. Now the rewards will be relative to bond size up to 900k rune (no additional rewards after that). E.g. they will get 3 times the normal reward if they have 3 times the minimum bond, which is sent to 300K.

100 Active Validators Reached

The required 100 active validators were reached, marking an important decentralised milestone for the network. The amount of nodes is limited to 100, however to a long standing bug, it is actually 101. Nodes are now voting to make it the limit 120 nodes.

Synths Maximum Cap Increased

Some pools have seen quick adoption of Synths up to the maximum 5% asset depth (2.5% of the pool) cap, and much higher overall trade volume were observed compared to pre-Synths. Nodes have voted to increase Synths maximum cap from 5% to 15% of asset depth of each pool. The Synths maximum cap is expected to be gradually raised until the maximum of 33% of asset depth.

THORFi Design Publicly Release

The THORFi design was publicly released on gitlab for review — https://gitlab.com/thorchain/thornode/-/issues/1255

It has taken months to design with many iterations, tweaks, and even wrong directions at times. It is complex and there are a lot of moving parts. The core team has been thinking hard on the concepts for a while, it’s easy to grow blind spots, bubble thinking. The design will undergo several more updates and tweaks as public feedback is received, before it is finalised.

Milestone Update

The below milestones are required before Mainnet. Only two points remain.

  • Launch Synths — Done
  • Hardfork and Cosmos SDK update — Done
  • Terra Launch and Kill Soft Cap in Chaosnet — Done
  • 100 Active Nodes Target — Done
  • Multiple Bond Providers —Done
  • Development of https://dev.thorchain.org/ — In Progress
  • THORName Service (TNS) Activation in Stagenet — Scheduled
  • TNS Activation in Chaosnet — Scheduled

30 Days of stable operations is required once all points are achieved. No date for Mainnet has been set but planning has started.

Wallets Not Handling Pending Deposits Properly

A quick check of most wallets reveal they don’t handle, or incorrectly handle, pending deposits. A pending deposit happens when 1 tx in a dual-sided deposit doesn’t go thru. The first asset is put in “pending” until it is matched.

Pending Asset Dump: https://pastebin.com/vNTDjRfc

Detect: {thornodeEndpoint}/pool/{pool}/liquidity_provider/{address}

https://thornode.ninerealms.com/thorchain/pool/BTC.BTC/liquidity_provider/thor13lqegruxnapq969vhtxgp7j2ct3t6aldxvt50w this shows the LP has their BTC in limbo, and should send in RUNE.

Wallet Developers and Users should be aware, users should ensure they are using the latest wallet software.

New Alpha XChainJS versions for Hard-Fork + Correction on REST Endpoint Deprecation

1. Alpha Versions of XChainJS for Hard-Fork:

📦 @xchainjs/xchain-cosmos@0.17.0-alpha.1

📦 @xchainjs/xchain-thorchain@0.24.0-alpha.1

These alpha versions should be fully compatible with post-hardfork (and pre-hardfork) THORChain. Note: these packages can be used now — they should work with current version of THORChain since the new APIs are already available. Please pull them in ASAP and report any issues here.

2. Correction on REST Endpoint Deprecation:

Counter to what the Cosmos SDK documentation reported, the endpoints listed in the below REST migration guide will NOT be deprecated in Cosmos SDK v0.45.x. They will be deprecated in Cosmos SDK 0.46. This means the following relevant endpoints will still work (for now):

- /bank/balances/{address}

-/auth/accounts/{address}

-/txs/{txhash}

-/txs/encode

-/txs/decode

Full guide:

https://docs.cosmos.network/master/migrations/rest.html

It is recommended to complete the REST Migration now to prevent issues down the line.
