Set Asset rate for DOT/KSM to enable treasury spends of DOT through Kusama OpenGov
Thanks to the Polkadot ecosystem's Interoperability and cross-consensus messaging through the Polkadot <> Kusama trustless bridge, DOT can be accessed directly on Kusama. When creating this post, there are around 4900+ DOT on Kusama. You can query the chain state to get the accurate number.
It is possible to send DOT to Kusama Treasury and access it through Kusama OpenGov. For the treasury tracks on Kusama to work as expected, a proper spend limits in terms of DOT need to be set. For this purpose, the asset rate parameter is used. For instance, DOT/USDC/USDT conversion rates were set on Polkadot through referendum 645, which allowed for Polkadot OpenGov to spend USDT/USDC directly through its treasury tracks.
It is worth noting that the current asset rate for DOT/USDC and DOT/USDT on Polkadot is 1 DOT = 10 USDC/T. This should not be confused as the actual exchange rate of the assets. Instead, the asset rate just applies this factor to adhere to spend limits. This rate can be adjusted through governance if the actual rate diverges too much.
In that light, the asset rate of 1 KSM = 4 DOT is reasonable to set, which translates to an asset rate of 25. We understand it is a bit counter intuitive. Please check the explanation below which converts assets into the smallest units (plancks) represnted on-chain:
- 1 KSM = 1000,000,000,000 (hence KSM token has 12 decimals)
- 1 DOT = 10,000,000,000 (hence DOT token has 10 decimals)
- 4 DOT = 40,000,000,000 when multiplied by 25 results in 1000,000,000,000 units which are interpreted as 1 KSM by Kusama OpenGov treasury tracks
This referendums sets asset rate for both XCM V3 and V4 locations for DOT through a batch call

Dear DrW3RK, Thank you for submitting your proposal. Trustless Core has voted AYE. To fully leverage interoperability within the Polkadot ecosystem and cross-consensus messaging through the Polkadot \<> Kusama trustless bridge, appropriate spend limits in terms of DOT must be established. A similar process has been successfully implemented in the past (DOT/USDT/USDC), setting a positive precedent. Best regards, Trustless Core.
PolkaWorld votes AYE! ✅
This is a historic moment — the Kusama Treasury is about to officially support DOT 🪙
Once passed, this proposal will not only address the technical points raised, but also unlock several key milestones with significant impact for both Kusama and the broader Polkadot ecosystem:
✅ Kusama Treasury can officially receive and use DOT
This marks a major step forward — the Treasury will no longer be limited to KSM, but will now be able to manage and distribute cross-chain assets.
Future grants can be issued directly in DOT, potentially attracting DOT-holding teams to participate in Kusama’s governance and ecosystem.
✅ Lays the groundwork for multi-asset treasury management
This isn’t just about enabling DOT — it opens the door to future support for assets like USDT, USDC, or BTC.
Kusama is becoming a more flexible treasury platform, able to onboard diverse funding sources for ecosystem growth.
✅ A real-world application of the Polkadot <> Kusama trustless bridge
The proposal showcases the real value of the Polkadot ↔ Kusama trustless bridge + XCM: not just asset transfers, but shared treasury governance.
Kusama and Polkadot are no longer separate silos — they are interoperable, cooperative systems.
✅ Brings DOT holders into Kusama’s ecosystem
In the future, DOT holders — users, developers, and teams — may be able to participate in Kusama governance without needing to convert to KSM.
