Each reading measures a different part of the ecosystem. Stablecoin supply is a balance, trading volume is turnover, and fees are a cost. Adding them together would mix those units and could count the same assets more than once.
Ripple’s Oct. 1 transparency figures put total $RLUSD circulation at $2,509.8 million, backed by $2,633.8 million in reserve funds. These issuer-wide figures cover $RLUSD across its supported blockchains. The backing consists of dollars and cash equivalents.
How XRPL activity uses $XRP
XRPL’s standard minimum transaction cost is 10 drops, equivalent to 0.00001 $XRP, before load scaling. Fees are destroyed. Congestion and special transactions can require more, while an eligible key-reset transaction can be free.
The fee follows the transaction’s processing cost. Moving a larger asset value does not, by itself, increase the $XRP fee in proportion.
Reserve requirements create a different obligation: currently 1 $XRP per account and generally 0.2 $XRP per qualifying owned ledger object. The first two trust lines are exempt when an account is funded with just the 1 $XRP base reserve; additional funding triggers normal charges.
These balances scale with accounts and objects. They represent $XRP held to satisfy reserve rules; transaction fees consume $XRP through burning.
Tokenized funds illustrate the distinction. Ondo’s tokenized Treasury product OUSG went live on XRPL in June 2025 with subscriptions and redemptions using $RLUSD. In its Aug. 3, 2026 ZILO and Licuido announcement, Ripple likewise described $RLUSD as the cash leg for delivery-versus-payment transactions and tokenized funds as collateral.
Brazil’s securities project makes the record-keeping role explicit. Ripple announced on Sept. 29, 2026 that the securities infrastructure operator CSD BR would initially mirror BTG Pactual fund-share records on XRPL. CSD BR’s own systems remain official for registration, deposit and settlement. Native issuance and trading among authorized participants are envisioned later, after the mirroring phase is validated.
Ripple Payments has a broader scope than activity on XRPL. Its March 3, 2026 platform expansion included fiat and stablecoin collections and payouts, with Corpay using $RLUSD for funding and settlement.
For lending, the documented Single Asset Vault design permits $XRP, trust-line tokens or Multi-Purpose Tokens. The Lending Protocol describes fixed-term, uncollateralized loans. $XRP-funded vaults would commit $XRP as loan principal.
Inventory is the larger test
$XRP‘s bridge role offers a route to larger liquidity demand. Auto-bridging can connect issued-token markets through $XRP when that route is cheaper, while direct routes or combinations of both remain possible. Cross-currency payments can also use $XRP conversion paths.
A bridge can buy $XRP on one leg and sell it on another, creating a temporary need for the token during the transfer. The continuing inventory question is how much $XRP intermediaries keep available between trades. Gross turnover leaves that balance unmeasured. A direct $XRP payment also moves existing balances; the transfer alone establishes neither a fresh market purchase nor net accumulation.
$XRP-containing AMM pools hold actual $XRP inventory while it remains deposited. Liquidity providers can redeem their shares. Pools containing two issued assets keep their trading principal in those assets.
These ecosystem totals leave incremental $XRP demand per dollar of activity unquantified. The decisive measurements are the share of activity routed through $XRP, the $XRP balances committed to liquidity, and how long those balances stay in place.
