Snowbridge, a trustless Polkadot-Ethereum bridge, has been now been live for over a year, running successfully with **no onchain issues and zero onchain downtime**. With our launch, we shifted to doing extensive marketing and business development work — the main milestone in our 2024 proposal was to successfully integrate with 6 parachains and we’ve radically surpassed that milestone:

* Snowbridge now has integrations with \~**24 parachains, wallets, apps, and other services** across the Polkadot ecosystem.
* Snowbridge has also grown to over $75M TVL, the **second highest across all protocols** on the Polkadot network.
* Snowbridge has seen an additional \~$15M in growth over the last month since our last failed proposal and we expect growth to continue further through the year.
* Snowbridge has become a **key piece of infrastructure** for most of the top products in the Polkadot ecosystem including Hydration, Asset Hub and Mythical:

This proposal is for a roadmap for the next year that covers:

* Deploying V2, an overhaul of our protocol with many new improvements
* Adding support for major Ethereum L2 chains
* Support for single-click, multi-hop swap and bridge transactions
* Simplifying the SDK developer experience and documentation
* Optimizing our light client for faster, cheaper bridging
* Giving OpenGov new superpowers that it can use to poach liquidity from Ethereum products
* Ramping up support for stablecoins and improve the UX of stablecoin-based payment flows
* Improving our consumer-targeted marketing efforts
* Improve the decentralisation of our off-chain components
* Continuing to operate, secure and keep the bridge up to date

The cost for this roadmap is **\~$1.87M.** The proposal also includes an additional **$300k** payment for a past failed transaction and a **$937.5k** retroactive payment for completed past milestones This brings the total cost of this proposal to **\~$3.1M.**

The roadmap payment is split into an advance payment and a completion payment in 1 year based on successful, on time delivery.

In contrast to our last failed proposal, this one completely removes our incentive funding and replaces it with runway funding, reducing the cost by $1.7M. It’s also a much simpler, more transparent payment structure with a stronger roadmap focus on unlocking growth.

The full breakdown of these roadmap items, as well as details on the cost and payment structure is in our full proposal here: [https://www.notion.so/snowfork/Snowbridge-2025-2026-Proposal-Redux-21f296aaabef803193e3f65b28fef1c5](https://www.notion.so/snowfork/Snowbridge-2025-2026-Proposal-Redux-21f296aaabef803193e3f65b28fef1c5)

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

## Complexity
- O(C) where C is the number of calls to be batched.
