Top 25 Seigniorage Cryptocurrencies for May 2026

Seigniorage cryptocurrencies are a class of digital currencies that use algorithms to control their supply, aiming to achieve price stability by expanding or contracting the number of tokens in circulation based on demand. They are designed to mimic the seigniorage process traditionally used by governments and central banks, which refers to the profit made from issuing currency, particularly when the face value of the currency exceeds its production cost. These cryptocurrencies often involve mechanisms such as rebasing, where the supply is algorithmically adjusted at regular intervals. Examples include Ampleforth (AMPL), which adjusts its supply daily in response to market conditions, and Basis Cash (BAC), which was inspired by the original Basis project (formerly known as Basecoin) that had similar goals but ultimately shut down due to regulatory concerns. Both aim for a stable value relative to some external reference, like the US dollar, through supply adjustments rather than being pegged directly to an asset or fiat currency.
