Calling smart contracts through a Snap

[Tranquil-Flow]

Hi there, I first heard of Metamask Snap last year at EthCC and loved the concept - finally getting around to playing with it now and just wondering if there are any examples out there of how one could call a smart contract function with a Metamask Snap. I'm looking to build a test snap to try perform a swap on the Uniswap router contract every time I do a transaction with Metamask. Suggestions/resources you can point to would be greatly appreciated!

From what I'm reading in the docs, the Snap could potentially interact with a dApp, which could then interact with Uniswap? Or perhaps directly from the Snap to Uniswap with the Uniswap SDK?

Hey @Tranquil-Flow you can use the wallet global object as a web3 provider, and so can use Ethers.js normally.

I've actually written a snap-arbitrage bot in the past. The code is now broken but the main ideas stand.

We're going to have a breaking change released in the next Flask which will require an additional permission to use wallet as a web3 provider, keep an eye out on Announcements.

Thanks @ritave ! I'll check out that repo and make sure to look out for those breaking changes.
