Multichain Track

Multichain track by Wormhole

Dive into the Multichain track and unlock the potential of blockchain interoperability with Wormhole. This track invites you to leverage Wormhole products and tooling alongside Solana’s capabilities to develop groundbreaking applications that operate across multiple blockchains. The track is split into two bounties, each with three prizes: (1) Wormhole Settlement, and (2) Native Token Transfers.

Track 1: Build Multichain Apps Using Wormhole Settlement 

Build your next multichain app using Wormhole Settlement - a suite of intents protocols enabling fast, multichain transfers. Wormhole Settlement enables efficient and scalable liquidity access across chains through unified Solana-based liquidity and permissionless onchain auctions.

Submission Requirements 

Submissions must integrate with one of the protocols included in Wormhole Settlement: Wormhole Liquidity Layer, Mayan Swift or Mayan MCTP. Projects must demonstrate functional integration on testnet (or mainnet) with supported Wormhole networks. 

Required Deliverables

• Open-source code with a well-documented repository

• Comprehensive README

• Verified transaction hash from Wormholescan on testnet

• Open Github repository

• Project demo link

• Concise project details

• Pitch deck (maximum 10 slides)

Resources and Documentation

• Settlement overview: https://wormhole.com/docs/learn/transfers/settlement/

• Build with Settlement: https://wormhole.com/docs/build/transfers/settlement/

• Mayan Swift: https://docs.mayan.finance/architecture/swift

• Mayan MCTP: https://docs.mayan.finance/architecture/mctp

• Mayan Swift demo: https://github.com/wormhole-foundation/demo-mayanswift

Prizes

• 1st: $2.5k

• 2nd: $1.5k

• 3rd: $1k

We reserve the right to adjust prize distribution based on the quantity and quality of submissions: (1) If no project meets our minimum standards, no prizes will be awarded; (2) If we receive submissions but they do not meet the quality we expect, we may reduce prize amounts or award fewer prizes than originally listed.

Judging Criteria

Technical Implementation (50%)

• Code quality and integration with Wormhole 

• Novel or creative approaches to solving technical challenges

• Feasibility and complexity of the design

• UI/UX quality and clarity

Impact & Viability (50%)

• Real-world usefulness and market potential

• Innovation and uniqueness of the concept

• Overall usability and user impact

• Team strength and execution toward delivering a meaningful solution

Bounty 2: Build Multichain Apps Using Wormhole Native Token Transfers (NTT)

Build your next multichain app using Wormhole’s Native Token Transfers (NTT). This open-source and composable framework lets you transfer native tokens across blockchains while maintaining their properties and preventing liquidity fragmentation.

Submission Requirements 

Submissions must integrate with Wormhole's Native Token Transfers (NTT) framework for cross-chain token transfers. Projects must demonstrate functional integration on testnet (or mainnet) with supported Wormhole networks. We recommend using the NTT CLI, but it is not mandatory. Integration with Wormhole Connect is encouraged but not mandatory (React widget).

Required Deliverables

• Open-source code with a well-documented repository

• Comprehensive README

• Verified transaction hash from Wormholescan on testnet

• Open Github repository

• Project demo link

• Concise project details

• Pitch deck (maximum 10 slides)

Resources and Documentation

Notes for hackers

When submitting please take note of the following:

Provide a TX hash from WormholeScan showing a successful crosschain transfer
Make the Wormhole implementation easily findable in your Github repo. Name a Wormhole or Multichain folder for instance so we can easily spot it 🙂

Only apply to the bounty if you attempted to integrate a Wormhole product. Only successful implementation will be eligible for bounties.

If you did not implement Wormhole but you would like to in your next iteration, please state this very clearly in your project description. Only successful implementation will be considered for bounties but we are happy to help you in your future implementation if you need guidance.
