XRP’s total supply is fixed at 100 billion with 55 billion locked into Ripple’s escrow accounts, limiting monthly market expansions to a maximum of 1 billion XRP. Ripple’s protocol allows unused escrowed XRP to be re-locked, meaning net new supply entering the market is often less than the upper limit, affecting liquidity and price movements. Investors should monitor net escrow flows, fee-induced XRP burns, and custody concentration to better understand XRP’s circulating supply and potential market impact.
