Building Croslend was an fun but we had some challenges along the way. One of the initial hurdles we encountered was the integration of Wormhole - since it was our first time using it. While the template provided on Wormhole's website laid the groundwork, adapting it to function seamlessly across any blockchain took a bit - we did get stuck for an embarrassingly long time on goerli & sepolia on Arbitrum + getting the gas. But we figured it out in the end.

The development of our smart contract, particularly the logic underpinning the cross-chain rebalancing, posed another significant challenge. The complexity of ensuring liquidity could not just be shared but dynamically balanced across chains required iterative testing and debugging.

Access to sufficient gas from testnet faucets also proved limiting. We couldn't mock as many transactions as we would have liked, and have to assume that the software will continue to work as more chains and users are added.

Amidst these technical challenges, we faced an unexpected hardware issue: one of our team member's laptop RAM failed. We lost a lot of progress on the website, but managed to performed some laptop surgery and got it working again!
