💸 This project won a $10K bounty at xHack hosted by Jump Crypto!

⚠️ The webapp and the contracts were created at a hackathon and might not be fully functional at the time of use. The project is not being actively maintained and is opensourced as an educational resource.

There are numerous defi strategies in the world of interoperable blockchains, but implementing on-chain executions in solidity is difficult. As defi grows, non-technical traders should have the tools to deploy custom strategies without writing code.

So we built xHolas, a plug-and-play defi strategy builder, to provide a no-code tool for executing cross-chain defi strategies with the following properties:

• batch execution: any number of txs should be executed with one signature
• cross chain: swaps/lending/borrowing/etc. should be executed across multiple chains within a single batch execution
• checkout the xHolas-contract repo for detailed smart contract architecture and deployments.

We learned a lot about wormhole's infrastructure, and for anyone hoping to add cross chain functionalities to their dapp using wormhole, we compiled the following resources:

• wormhole developer docs: https://book.wormhole.com
• wormhole deployed contracts: https://book.wormhole.com/reference/contracts.html
• wormhole sample projects: https://github.com/wormhole-foundation/xdapp-book/tree/main/projects
• Setting up wormhole dev environment
  1. running local testnets and guardians:

  2. running Redis (a queue for storing VAAS) and then the SpyListener/RESTRelayer/WalletMonitor:
