Total Supply and Issuance

Why XRP's supply was fixed at 100 billion at genesis, and why no new XRP can ever be created.

A fixed supply, set at genesis

All 100,000,000,000 (100 billion) XRP that will ever exist were created in a single genesis event when the XRP Ledger launched in 2012. There is no mining, staking issuance, or any other protocol-level mechanism to create additional XRP after that point — the maximum supply is a hard ceiling baked into the ledger's rules from the start, not a target or a schedule.

This is a meaningfully different model from Bitcoin, where new BTC is issued gradually over roughly 130 years through mining rewards, or from many proof-of-stake networks, where new tokens are issued continuously as staking rewards. XRP has no equivalent of either.

Supply only moves in one direction: down

Because every transaction fee is permanently burned rather than paid to a miner or validator, the total supply of XRP is strictly non-increasing — it can only stay the same or decrease, transaction by transaction, forever. In practice, the amount burned per transaction is extremely small, so this reduction happens gradually rather than dramatically, but the direction is structurally guaranteed by the protocol.

Total supply vs. circulating supply

"100 billion XRP" describes the total supply — the absolute maximum that could theoretically be in someone's hands. It is not the same as the circulating supply — the amount actually available and moving in the open market at a given time — because a substantial portion of the total supply is held in Ripple's own escrow program and has not yet been released. See Circulating vs. Total Supply for how to think about that distinction.

Where the initial supply went

At genesis, the XRP Ledger's creators allocated a large share of the newly-created supply to the company that would become Ripple (originally OpenCoin), to fund its development and operations, while distributing other portions to the founders individually and, over time, through various giveaway and ecosystem-development programs. See Distribution and Early History and Ripple's XRP Holdings for more detail on how that initial allocation has been managed since.
