Introduction
In 2025, the intersection of decentralized finance (DeFi) and central bank digital currencies (CBDCs) is reshaping global finance, with blockchain interoperability as a key enabler. Quant Network’s QNT token, priced at $114.39 with a $1.38 billion market cap as of August 2025, powers the Overledger operating system—the world’s first blockchain OS—facilitating seamless connections across diverse networks. As DeFi protocols expand and CBDCs gain traction, QNT’s utility in bridging siloed blockchains has driven a 13% price surge post-Overledger Fusion launch in June 2025. With partnerships like Oracle and the Bank of England, QNT is positioned as a key player in regulated and decentralized ecosystems. This blog outlines the top 5 use cases for QNT in DeFi and CBDCs, highlighting its role in interoperability, tokenomics, and enterprise adoption. From CBDC settlements to DeFi protocol enhancements, QNT’s applications demonstrate its potential to unlock trillions in value.

1. CBDC Settlement and Cross-Border Payments
Quant’s Overledger technology is instrumental in CBDC development, enabling secure, interoperable settlements across global financial systems.
- Overview: QNT facilitates CBDC interoperability by connecting public and private ledgers, allowing central banks to issue and transfer digital currencies seamlessly. In 2025, Quant contributes to projects like the Bank of England’s Digital Pound and EU CBDC trials, using Overledger for multi-ledger rollups.
- QNT’s Role: As a utility token, QNT is used for transaction validation and licensing on Overledger, with enterprises paying fiat converted to QNT for access. This creates demand through locked licenses and staking.
- Impact in 2025: With CBDCs projected to handle 15% of global payments, QNT’s involvement in Project Rosalind (a BIS-led initiative) positions it for widespread adoption, potentially boosting token value by 20% via increased network activity.
- Example: A central bank uses QNT-powered Overledger to settle cross-border CBDC transactions between the Digital Pound and Euro CBDC, ensuring compliance and instant finality.
This use case underscores QNT’s enterprise focus, distinguishing it from DeFi-centric tokens.
2. Enhancing DeFi Protocols with Multi-Chain Smart Contracts
QNT enables DeFi protocols to operate across multiple blockchains, reducing fragmentation and improving efficiency.
- Overview: Overledger allows developers to deploy smart contracts that interact with Ethereum for DeFi lending and Hyperledger for private settlements, enhancing protocols like Aave or Uniswap equivalents. In 2025, DeFi TVL reaches $500 billion, with interoperability driving 40% of growth.
- QNT’s Role: Developers use QNT for MApp (multi-chain app) licensing and transaction fees, enabling cross-chain executions without bridging risks. The token’s fixed supply (14.6 million) ensures stability amid rising demand.
- Impact in 2025: QNT’s integration boosts DeFi liquidity by unifying assets, with Overledger Fusion supporting stablecoin swaps in DeFi pools. This could increase QNT’s utility demand by 25%, per market analyses.
- Example: A DeFi platform uses QNT to execute yield farming across Ethereum and Solana, automating cross-chain collateral transfers via Overledger.
QNT’s interoperability reduces DeFi’s silo effect, making it essential for scalable protocols.
3. Stablecoin Interoperability and Tokenized Assets
Overledger Fusion, launched in 2025, revolutionizes stablecoin use in DeFi and CBDCs by enabling seamless cross-chain transfers.
- Overview: Fusion acts as a Layer 2.5 solution for unified stablecoin representations, supporting USDC, Tether, and CBDCs in DeFi lending or tokenized bond markets. Stablecoins dominate 70% of DeFi volume in 2025.
- QNT’s Role: QNT powers Fusion’s Trusted Node Program for staking and validation, locking tokens to secure the network and reduce circulating supply. Enterprises convert fiat to QNT for access, driving demand.
- Impact in 2025: Fusion targets tokenized assets like bonds, with partnerships enabling CBDC-stablecoin hybrids, potentially adding $50 billion in liquidity to DeFi.
- Example: A DeFi user swaps USDC on Ethereum for a CBDC on a private ledger via Fusion, paying QNT fees for instant, compliant transfers.
This use case bridges DeFi and traditional finance, amplifying QNT’s value.
4. Programmable Finance and Compliance Automation
Quant Flow, integrated with Overledger, uses QNT for automating compliant workflows in DeFi and CBDCs.
- Overview: Quant Flow’s PayScript® automates financial processes like remittances and compliance across chains, supporting DeFi lending and CBDC distributions. In 2025, programmable finance grows 50% amid regulatory demands.
- QNT’s Role: QNT is staked for Flow’s operations and used for transaction fees, with locked licenses reducing supply. This creates scarcity amid adoption.
- Impact in 2025: Flow enables DeFi protocols to comply with KYC/AML for CBDC integrations, unlocking institutional capital inflows.
- Example: A DeFi platform automates CBDC-backed loans using Flow, validating transactions with staked QNT for secure, compliant execution.
QNT’s utility in automation makes it vital for regulated DeFi.
5. Healthcare and Supply Chain Integration with CBDCs
QNT extends to non-financial sectors like healthcare, using DeFi and CBDCs for secure data sharing and payments.
- Overview: Overledger connects blockchain for tokenized health records and CBDC payments in supply chains, enhancing DeFi’s real-world applications. Healthcare blockchain grows 30% in 2025.
- QNT’s Role: Developers use QNT for licensing to build MApps that integrate CBDCs for payments and DeFi for funding.
- Impact in 2025: Enables compliant CBDC use in supply chains, with DeFi protocols funding tokenized assets.
- Example: A healthcare provider uses QNT-powered Overledger to settle CBDC payments for DeFi-funded medical supplies, ensuring interoperability.
This expands QNT’s scope beyond finance.
Challenges and Considerations
- Competition: Polkadot and Chainlink challenge QNT in interoperability.
- Volatility: QNT’s price fluctuates with market sentiment.
- Regulation: EU AI Act impacts CBDC integrations.
