Back when Canadians used to travel to the US, it was common for a situation like this to arise: "Hey, I'll send you money. Do you have Venmo?" And then, as a Canadian, you'd say, "sorry, we don't have Venmo in Canada. We use our own proprietary system called Interac e-Transfer. Do you have PayPal? I think I still have an account. Let's try." Once this exchange was over, both parties would then sit there and wonder why the hell it's still so expensive and awkward to move money around.

As another example, take global remittances. These are payments sent by a person back to their country of origin, usually to a family member. And in 2024, it was estimated that some $905 billion was sent around the world for this reason, with about $685 billion of it being sent to low and middle-income countries. But it was also estimated that the average cost of doing this was around 6.62%, which is double the UN's target of 3%.

For anyone who has used crypto before, this feels painfully archaic. Sending a wire transfer can cost over $50 and it can take time to clear, assuming that you got in before the bank's cut-off time. Sending things via a blockchain is cheap (it's pennies now) and it happens instantly and securely — 24 hours a day, 365 days a year. This was always one of the promises of crypto, but now we're seeing it play out very clearly with stablecoins. Here's an example.

Stablecoins are a type of cryptocurrency that have their value pegged to another asset, such as gold or a fiat currency. And at the time of writing this post, something like 99% of stablecoins are pegged to the US dollar. The benefits of this are twofold. Firstly, it creates price stability. You're effectively holding US dollars. But now you have a US dollar on a blockchain (or a tokenized US dollar), meaning you can do crypto things with it, like send it around the world instantly and for free.
