Hypha’s role on the Hub
Announced at Cosmoverse this year, Hypha will be taking on the role of Cosmos Labs’ implementation partner on the Hub through the end of 2025 and into 2026. This means that we will be taking on additional incident response, integration and deprecation, and dev maintenance work on the Hub, all under the direction of the Cosmos Labs team.
Context
Since the start of 2025, Hypha has held a mandate as the Hub’s testnet and mainnet operations team, ratified by [Proposal 985]( Mintscan ) with a budget of 650k from the community pool. Our mandate is to steward the Hub’s testnet, train validators, coordinate mainnet upgrades, provide ICS support for new and existing consumer chains, and work closely with the Cosmos Labs team (formerly Interchain Labs).
This report summarizes our work throughout 2025-Q3 and plans for the coming quarter, per our commitment to transparency reporting on work performed with community-disbursed funds.
You can give us feedback on our work via our form [here]( Feedback ).
Highlights
Permissionless CosmWasm goes live on the Hub
-
Proposal 1007 passed on August 20, switching CosmWasm from governance-gated upload to permissionless upload
-
Provider testnet followed suit shortly afterwards
-
Still in-progress working on getting contract explorer support
-
A signalling proposal (1010) to integrate the tokenfactory module has also passed
Smart contract pixel game day on the testnet
-
Making use of permissionless CosmWasm on the testnet
-
Hypha wrote a contract and created a game where users could compete to change the colours on a pixel map
-
The pixel map looked like this at the end of the event.
Mainnet transaction emulation routine
-
A new tool, the chain mimicker, was built and deployed to generate baseline traffic in the testnet that mimics the messages going through the Hub. These transactions exercise the authz, staking, distribution, wasm, and IBC functionality of the testnet.
-
This tool will work with any Cosmos SDK chain and can be extended to support additional messages.
-
The repo for the chain mimicker can be found here.
Challenges
Delayed August TIP payouts
-
Due to operational delays, payouts for the August TIP period took place quite late (end of September)
-
This issue should not reoccur in monthly payouts, though there may be delays for giving newer validators time to complete KYC

Financial updates
Our cashflow report is very simple this year as we are billing a consistent amount each month and not processing any returns.
For transparency, we hadn’t linked our withdrawal tx for Jun 2025 as it hadn’t happened yet at the time we posted our last update. For Jun 2025, we billed 54,166.67 USDC withdrawn on Aug 3 (tx here).
-
Jul 2025: Billed 54,166.67 USDC, withdrawn on Aug 3 (tx here).
-
Aug 2025: Billed 54,166.67 USDC, no withdrawal yet.
-
Sep 2025: Billed 54,166.67 USDC, no withdrawal yet.
-
Remaining USDC: 160173.0436
Please note - this ‘remaining USDC’ balance is an accounting representation of what remains, not what is physically present in the wallet. Additionally, due to our ATOM-USDC conversion in the last quarter, this balance is not quite enough to add up to our budget, so there will be one smaller bill in our final quarter of work.
Plans for Next Quarter
Our plans for the coming quarter include all of our usual work funded by our proposal (release testing, scheduling and coordinating mainnet upgrades, managing the provider testnet, stewarding the Testnet Incentives Program).
While not within the scope of this proposal, we feel the community deserves a light update on our work plan in our new role as Cosmos Labs’ implementation partner on the Hub. We will be:
-
Developing incident response plans with Hypha as the first responder
-
Designing a tokenfactory implementation plan for community approval
-
Scoping the technical deprecation of Interchain Security
Feedback and Responses
So far we have received one piece of feedback!
What would you like to tell us about our testnet work, including the Testnet Incentives Program, validator education, upgrade smoke testing, and being a platform for development?
- Best organised and implemented program in Cosmos. Extremely useful for validator education and testing out new features before Mainnet. We also found the performance testing valuable and insightful.
What would you like to tell us about our mainnet coordination and support work, such as Hub upgrades and supporting new and existing consumer chains?
- Best organised upgrades in Cosmos, especially useful with the added intricacies of consumer chains.
In our final quarter of work on the Hub, we would greatly appreciate any additional feedback from the community. You can offer us feedback via our form here.
As a reminder, our mandate on the Cosmos Hub is to:
-
Steward the Hub’s testnet as a platform for validator education, final runway for Hub upgrades, and stable development platform. The provider testnet’s purpose is to serve the Hub’s direct needs.
-
Provide mainnet and Interchain Security coordination support for validators and consumer chains.
-
Provide development support for the Hub team at Cosmos Labs.
