Stellar vs Quant
New to ISO 20022, the bank-messaging standard? Start with the plain-English guide. SWIFT postponed its November 2026 wave with no new date; see the deadline tracker.
XLM is a Layer 1 for remittances and stablecoins whose SEP standards are not ISO 20022 message formats (and which is often described as an RMG member but is not listed); QNT is an interoperability layer that Quant describes as ISO 20022-native, rather than a chain that settles on its own
How Stellar and Quant differ
Stellar settles payments on its own ledger, while Quant links other ledgers together. Stellar's ledger updates every 5 to 7 seconds, its network minimum is 0.00001 XLM per operation, and the 5,000 TPS figure is a 2025 goal. Quant's Overledger has no chain, TPS or finality of its own, and QNT is an ERC-20 token whose supply figures differ by source: a widely cited 14,612,493 against a contract reading of 45,467,000 on September 29, 2026. Stellar's reach in its profile is cash-to-crypto ramps in 100+ countries and territories per the SDF, and Quant's is engagement with UK banks, The Clearing House and the Bank of England.
ISO 20022 standing: XLM vs QNT
Neither is on ISO's Registration Management Group member list: Stellar is often described as a member but no Stellar-named entity appears on the list archived in March 2026, and Quant is openly not a member. Stellar's SEP-31 and SEP-9 are not ISO 20022 message formats, and SEP-9 only borrows ISO encodings for language, country and date. Quant takes a different route: it pitches Overledger as connecting any chain to systems that speak ISO 20022, a design claim rather than a certification. The site scores ISO integration 4 for XLM and 6 for QNT.
What to watch on each side
Stellar's items are Soroban's early ecosystem and PYUSD volume, plus whether more fintechs choose it for stablecoin issuance. On September 22, 2026, BVNK, which Mastercard completed acquiring on August 3, 2026 according to BVNK, announced a Stellar integration live for enterprise customers in 130+ countries, a payments integration rather than any ISO 20022 certification. Quant's items are the US On-Chain Money Initiative, expected available in the first half of 2027, and Fusion adoption.

| Transaction fee | 0.00001 XLM minimum (100 stroops) | Depends on connected chain | Fee tier: XLM Negligible, QNT Variable |

Questions about XLM vs QNT
Which project's token is needed to use the platform?
Quant's profile says, citing Genfinity, that organizations pay for Overledger licenses in QNT, but it could not confirm that against Quant's own documentation, and it notes that bank adoption does not automatically translate into QNT demand. XLM's role in the Stellar profile is smaller: the network minimum fee is 0.00001 XLM per operation.
Which one is linked to Mastercard?
Stellar, in two ways. The SDF announced in October 2024 that Stellar was joining the Mastercard Crypto Credential ecosystem, and BVNK, which Mastercard completed acquiring on August 3, 2026 according to BVNK, announced a Stellar integration on September 22, 2026. The Quant profile mentions Mastercard only in the biography of its founder, Gilbert Verdian, who held a private-sector role there.
Who founded each project?
Stellar was introduced in 2014 by Jed McCaleb, who had earlier created the technology behind the XRP Ledger at Ripple, and Joyce Kim, the two cofounders of the Stellar Development Foundation, a nonprofit. Quant was founded in 2018 by Gilbert Verdian and is UK-based.
Can I convert or swap XLM to QNT?
Yes, through an exchange or a crypto-to-crypto swap service that lists both coins. Before you swap, compare the fees and the exchange rate, send each coin on the right network to the right address, and check the platform works in your region. Same steps for QNT to XLM.
