Topic 1: Build anything on top of Bifrost XCM

The only restriction for this topic is to call xcm_send on Bifrost-Polkadot. You're free to build any use case on top of it. This can involve a series of calls or a simple call between parachains. However, calling between Bifrost and Ethereum via Snowbridge is recommended. Key points:

Call xcm_send on Bifrost, do any cases as you want.

Topic 2: Liquid Staking Router (500 BNC)

Build a liquid staking router that allows users to cross DOT from a source chain and stake with Bifrost vDOT in just one click. For instance, this could involve batching DOT cross-chain transfers from the Relay-chain to Bifrost, minting DOT to vDOT, depositing vDOT into LoopStake with 2x leverage, or cross-chain depositing vDOT into Hydration Omnipool. Build at least 2 use cases in Bifrost-Polkadot and 1 case in cross-chain scenario.

Demonstrate the process in a production environment (wss://hk.p.bifrost-rpc.liebi.com/ws).

Topic 3: Leverage off SLPx (800 BNC)

You can build novel applications under this topic by integrating SLPx. SLPx is a set of SDKs deployed on multiple chains, allowing various use cases to integrate with Bifrost liquid staking.

Key points:

Develop in an environment supported by SLPx,
