Hard Cap

A Hard Cap is the maximum limit on the total number of tokens that will ever be issued by a specific blockchain protocol. Once this limit is reached, no more tokens can be minted, effectively making the asset supply-constrained or deflationary if tokens are burned.

This feature is often used to create digital scarcity, similar to the supply limit of Bitcoin. The hard cap provides a predictable monetary policy that investors can rely on when assessing long-term value.

It eliminates the risk of arbitrary inflation by central authorities or protocol governance. In the context of tokenomics, a hard cap is a strong signal of value accrual potential for holders.

However, it also requires the network to find alternative ways to incentivize participants once the minting rewards end. It is a foundational element of many store-of-value digital assets.
