TL;DR
Multix will stop working on January 1, 2026.
We (the PAPI team) planned to take over Multix and continue maintaining and improving it, especially to reduce its reliance on indexers and to push multisig UX forward across Polkadot ecosystems (including better support for ETH-like chains such as Moonbeam).
We discussed this plan with Nico (Velocity Labs) and Alberto (Papermoon), and we were told that the DeFi Infra Bounty would support this effort. However, following recent changes around OpenGov and the resulting constraints on bounty funding, we were informed that the bounty can no longer support Multix. We attempted to find an alternative solution with the Web3 Foundation (W3F), but we haven’t reached a workable outcome.
As a result, we cannot sustain Multix’s operational costs, and we will be shutting it down on January 1, 2026.
What we wanted to do with Multix
In our view, Multix is currently one of the best tools for managing multisig calls on Polkadot.
But we’ve also believed for a long time that it could be significantly better, especially if it didn’t depend so heavily on indexers. Ever since @voliva published the stateless multisig tooling experiment, we’ve been thinking about what it would take to build multisig tooling that:
- doesn’t rely on indexers as a hard dependency,
- can be integrated directly into wallets and extensions, and
- helps make multisig signing flows feel like first-class citizens across the ecosystem.
When we were approached about taking over Multix, we were excited because it felt like the right opportunity to evolve Multix in that direction, incrementally and responsibly, while collaborating with wallets and extensions to standardize better multisig signing experiences.
We also wanted to fully support ETH-like chains (e.g., Moonbeam) across Multix and the associated libraries.
To be clear: our intention was never to “just keep the lights on.” The plan required growing our team and working towards those ambitious goals, and we were only interested because we believed there was alignment (and budged) to make that possible.
That’s also why we invested significant time reviewing the codebase and preparing a concrete plan for how we would take Multix forward.
Why Multix is shutting down
In the final stretch (after the repository, domain, indexer, and infrastructure were transferred to us) we were informed that the DeFi Infra Bounty would not be able to fund the initiative.
We reached out to both Parity and W3F to explore alternatives and explain the situation clearly:
- Multix has non-trivial running costs.
- We had already invested substantial time preparing the transition and roadmap.
- We were open to other funding paths or solutions.
So far, we haven’t found a workable path forward.
Given the current situation, and the fact that Thibaut’s original plan was to shut Multix down at the end of the year, we can’t responsibly commit to ongoing infrastructure and maintenance without funding.
Therefore, we will be shutting down Multix on January 1, 2026.
We genuinely wish this had gone differently.
Timeline of events
- Oct 28, 2025: Thibaut announces Multix will shut down at the end of the year.
- Oct 30, 2025: Alberto (Papermoon) reaches out to ask whether we’d take over Multix. From the start, we make it clear we would only do so if there was budget to support not just maintenance, but meaningful improvements. Alberto supports the direction and says the DeFi Infra Bounty could help fund it.
- Nov 10, 2025: First meeting with Thibaut to discuss plans. He’s supportive and happy that a team would continue Multix.
- Nov 13, 2025: We publicly announce that the PAPI team will take over Multix.
- Nov 16, 2025: In-person meeting during Sub0 with Nico and Alberto to discuss budget and roadmap. We’re asked to fill out a form; discussions are supportive.
- Dec 1, 2025: Seeing that W3F is closing bounties, we reach out to ask whether Multix is safe given our plan to rely on DeFi Infra Bounty support. We’re told they do not intend to close bounties that are working well.
It would be counter productive to close bounties like DeFi bounty which are working
- Dec 9, 2025: Thibaut transfers infrastructure (domain, indexer, etc.) to us.
- Dec 18, 2025 (EOD): Alberto informs us that due to the new OpenGov situation, the DeFi Infra Bounty won’t be able to support Multix.
- Dec 19, 2025: We reach out to W3F to find an alternative solution. We explain the operational costs and the work already invested. We say we’re open to alternatives, but we can’t keep Multix running without funding. We’re told they will discuss internally and get back to us.
- Dec 22, 2025: We reach out again suggesting we should inform the community that Multix will go offline on Jan 1. We’re thanked for the update, told the message has been relayed, and informed they are on vacation.
