Acala

Acala is building the liquidity layer for web3 finance that is captive and sustainable. It aims to provide infrastructures for HyFi (DeFi+CeFi) solutions with crypto and real-world assets. Acala offers a Universal Asset Hub that hosts multichain liquid staking token (LST) protocols (such as liquid DOT - LDOT), an AMM decentralized exchange, and an app platform that is EVM-compatible and highly customizable (based on Substrate). Acala is secured by Polkadot, and is the liquidity gateway of Polkadot parachains and L1/L2 blockchains.

Bifrost & Moonbeam

Bifrost is a modular programmable dedicated liquid staking middle layer serving the omnichain ecosystem. Built on Substrate, powered by Polkadot. Bifrost has created a cross-chain interaction Pallet for vToken based on XCM called the SLPx. The SLPx is an extension pallet to Bifrost SLP that will allow users to invoke SLP's functionality on a remote chain without crossing assets into the Bifrost chain, allowing users to mint, redeem, swap vTokens remotely on the target chain. For users, the minting, redemption, and swapping of vTokens have been simplified, as they can now be directly performed on EVM chains such as Ethereum and parachains such as Moonbeam, Moonriver and Astar without cumbersome cross-chain operations all through one single interface, the recently launched Omni LS DApp powered by SLPx. More information on SLPx technical integration

Moonbeam serves as the EVM smart contract hub on Polkadot providing flexible and powerful smart contract solutions to the Polkadot ecosystem with XCM capabilities.

Bounty Ideation

Combining the features of Moonbeam and Bifrost, participants can develop LST (vToken) related applications based on Moonbeams’ EVM-compatible environment. For reference, specific bounty entries can be made from the following perspectives:

1.DeFi applications built around Bifrost LST vTokens, including but not limited to lending/borrowing, trading, leverage yield strategies, etc. We aim to build innovative vToken DeFi applications to achieve open, transparent decentralised financial solutions across Polkadot EVM and Substrate ecosystems.

2.Provide a vToken App, dashboard or analytics in the Moonbeam ecosystem with customizable UI to guide users to using vTokens and interacting with other native DeFi protocols in the Moonbeam ecosystem.

Bounty Challenges - Description

Key points: LST、Omni-chain, Moonbeam EVM、Bifrost SLPx, Omni LS, Polkadot XCM

  • Create a dedicated vToken Dashboard on Omni LS DApp (powered by SLPx).

An interactive tool that compares existing yield and LP opportunities for Bifrost vTokens across native Moonbeam protocols and Substrate chains. This tool can show current yields vs. other providers, historical yield, and other metrics which are worth considering.

  • Build a vToken yield trading protocol

Build a permissionless yield-trading protocol where users can execute various yield management strategies for their vTokens- splitting yield bearing assets into a fixed yield (i.e. earn fixed yield on vDOT) and long yield (i.e. bet on vDOT yield going up by purchasing more yield) component. Examples of existing protocols in this space are Pendle Finance, Spectra, Flashstake.

  • Create an automated yield strategy aggregator for vTokens Implement automated liquid staking yield strategies in yield farming protocols on native Moonbeam DeFi protocols (Beamswap, Stellaswap, Moonwell, Prime Protocol).

An interactive tool that compares existing yield and LP opportunities for Bifrost vTokens across native Moonbeam protocols and Substrate chains. This tool can show current yields vs. other providers, historical yield, and other metrics which are worth considering.
