Polkadot's on-chain governance has approved treasury funding for the next six months of Chainflip's Asset Hub integration work. The proposal, known as Referendum 1913, passed with 94.9% support from DOT holders and the Polkadot Treasury participating in the vote.
The vote was decided by the Polkadot community & DAO through Polkadot's own on-chain governance. What it tells us is that the DOT community want this collaboration to continue. That is a good result for Chainflip and the DOT community to allow for more dedicated work on Asset Hub.
Chainflip's Polkadot AssetHub Integration: Live in SubWallet, Talisman, and Beyond
The Chainflip integration for Polkadot Asset Hub has been in production since July 30, 2025, and is accessible directly through SubWallet, Talisman and a variety of other different integrations.
Supported assets include:
Native DOT on Asset Hub
USDC and USDT on Polkadot Asset Hub (hubUSDC, hubUSDT)
Routing between these Polkadot assets and native BTC, ETH, USDC, USDT, SOL, ARB, TRX, and other Chainflip-supported assets
Every swap settles in the native asset on the destination chain. No wrapped tokens, no bridging step, and no centralised exchange account. That part of the integration is unchanged by Referendum 1913; the new funding is about keeping it maintained and adding new capabilities.
What Referendum 1913 Funds: Three Milestones on the Chainflip Asset Hub Integration
The funding is split across three deliverables over six months, plus ongoing maintenance of the existing integration.
Milestone 1 (August 2026): Making Chainflip's Polkadot Asset Hub Integration More Resilient
An upgrade to how Chainflip's validators observe activity on Asset Hub. The new design spreads that observation work across a rotating group of validators instead of relying on a fixed subset. The practical effect is a more resilient integration that is easier to keep updated as Polkadot's software evolves.
Milestone 2 (October 2026): Chainflip Testing Moves to Polkadot's Paseo Testnet
Move Chainflip's Asset Hub testing onto Paseo, Polkadot's community testnet. This retires a custom test environment Chainflip has been running separately and brings the integration in line with how the rest of the Polkadot ecosystem tests changes. Fewer moving parts on the Chainflip side, closer alignment with Polkadot release cycles.
Milestone 3 (December 2026): Bitcoin-to-Polkadot Smart Contract Calls in One Transaction
Extend Chainflip's cross-chain messaging to Polkadot Asset Hub. Today, a swap recipient can trigger a smart-contract call on Ethereum or Solana in the same transaction as the swap itself. Milestone 3 adds Polkadot to that list.
In practice, this means a Bitcoin holder will be able to swap to a Polkadot Asset Hub asset and interact with a Polkadot DeFi contract in one signature, without a separate follow-up transaction. It is the most user-visible piece of the roadmap, and it lands in December 2026.
Why Referendum 1913 Is a Positive Result for Chainflip and DOT Holders
Three points, in plain terms:
The Polkadot integration keeps improving without pulling on Chainflip's general resources. Polkadot-specific work is now funded by Polkadot-specific revenue. That frees the Chainflip team to focus on other chains and other integrations, while the Asset Hub work continues in parallel.
The funding is transparent, and the code is open. Every deliverable will be released under Apache 2.0. Status reporting is part of the maintenance scope, and progress is publicly visible on Subsquare and Chainflip's GitHub.
Milestone 3 adds a real new capability. Cross-chain smart-contract calls into Polkadot open up composability with Polkadot Hub DeFi that did not exist before through Chainflip. That is worth watching in December.
When Each Chainflip Asset Hub Milestone Lands
The milestones deliver in sequence:
M1 completes August 2026
M2 completes October 2026
M3 completes December 2026
Progress updates and code drops will be public. The Chainflip / Asset Hub route remains live now via swap.chainflip.io, SubWallet, Talisman and other integrations.

What is Polkadot Referendum 1913?
A treasury proposal on Polkadot's on-chain governance system that approved $375,777 USDC in funding to Chainflip Labs for continued maintenance and feature development of the Polkadot Asset Hub integration inside the Chainflip protocol. It passed with 94.9% support from DOT holders participating in the vote.
What does the funding cover?
Three deliverables over six months plus ongoing baseline maintenance: an upgrade to how Chainflip's validators observe Asset Hub activity ($116,667), a move to Polkadot's Paseo community testnet ($103,101), and cross-chain smart-contract call support for Polkadot Asset Hub ($156,009). The baseline covers validator operations, software upgrades, security monitoring, and status reporting.
When did Chainflip's Asset Hub integration go live?
The public launch was July 30, 2025, integrated in SubWallet, Talisman and a broad range of integrators. Supported assets include hubUSDC, hubUSDT, DOT, plus native BTC, ETH, and USDC on other chains, with settlement in the native asset on both ends of every swap.
Is Chainflip's Polkadot code open source?
Yes. All Chainflip repositories, including the Polkadot Asset Hub integration, are released under Apache 2.0.
What changes for users?
Nothing changes right now: the existing Asset Hub integration keeps working through swap.chainflip.io and SubWallet. The main user-visible change lands in December 2026, when a swap recipient will be able to interact with a Polkadot Asset Hub smart contract in the same transaction as the swap.
Where can I follow progress on the milestones?
Status reporting is part of the referendum's maintenance scope and will be posted publicly. Code drops will land in the open-source Chainflip repositories under Apache 2.0. Live Asset Hub swap activity is visible on Chainflip Scan.
