Since you sold the crypto, it's considered a capital gain/loss. You'll need to report each transaction individually using the records from Wealthsimple. Make sure to calculate the gains/losses for each transaction and report them accurately.
As for your work, if it wasn't formal employment, you don't need to report it under the self-employment section. The capital gains reporting already covers the earnings from your side hustle.
If you need further assistance, consider consulting a tax expert to ensure everything's in order. By the way, have you checked a white label crypto exchange? It might be useful for your future crypto endeavors.
