#20·Snowbridge Launch and Treasury Proposal

Launch

Snowbridge is live! We've been up for ~ 2 weeks, running smoothly since launch, with no issues and usage is starting to grow.

If you're not familiar with it, it's a bridge between Polkadot and Ethereum that is designed and implemented to be fully trustless, with no multi-sig or third party involved. It’s a major innovation for interoperability in the Polkadot ecosystem.

Snowbridge is one of the longest running and most complex public goods project in the Polkadot ecosystem outside of Parity itself, and many teams have eagerly awaited the launch.

We've also already finished off 3 - 4 integrations with other teams, and are expecting to ramp up integrations across all parachains over the next month before a wider growth and adoption program.

If you missed the launch, see more details in our blog announcement here and try it out yourself using the app here.

Treasury Proposal

With the launch done, we’ve completed all our milestones from our original proposal in 2022 and are set up for the long term success of the bridge. In that proposal, our team and the Polkadot community agreed upon our expected milestone payments and incentives which totalled to ~$10 mil worth of DOT.

This proposal finalizes the payments for our 2024 completed engineering milestones, operating costs and team incentives. It also adds additional controls on those team incentives to ensure strong alignment between the team and the Polkadot community, and gives medium-term insurance guarantees to bridge users.

The proposal is long as it documents a lot of the work we've been doing over the last 2 years as well as future plans, but we're looking for any early support, feedback and discussion here before going live with the proposal.

The executive summary of the propsal is copied below, and the full proposal is here:

See the Completed Work and Future sections in the full document for a summary of our completed milestones, last year of work and future plans.

Our last successful proposal was in 2022, where our team and the Polkadot community agreed upon our expected milestone payments and incentives. The agreed total milestone payments and incentives totalled ~$10mil worth of DOT.

This proposal finalizes the payments for our 2024 completed engineering milestones, operating costs and team incentives. It also adds additional incentive alignment controls and medium-term insurance guarantees for the bridge. Further details on the payment and incentive structure, see the full document.

A summary diagram of payment flows:

The execution is a batch transaction, with spends that are delayed over the next year to cover all 4 payment buckets mentioned. There is a table that specifies the amount, validFrom and days delayed of each spend in a much simpler, easier to read form at the end section of the full proposal, linked above.
