Chainlink Deepens Its Aptos Integration With Decibel as the Flagship Partner

Chainlink integrates with Aptos, bringing Data Streams and DataLink to the network with Decibel as the flagship partner for accurate and efficient DeFi trading.

Chainlink has integrated with the Aptos blockchain, introducing its Data Streams and DataLink services to developers across the network. Aptos confirmed that Decibel, a decentralized derivatives platform, will serve as the flagship launch partner for this rollout.

This integration gives Aptos developers access to low-latency market data and institutional-grade information, improving accuracy and reliability across decentralized finance (DeFi) applications.

What Chainlink Brings to Aptos

The integration includes two core services now available on Aptos:

• Chainlink Data Streams: Provides developers with real-time, low-latency market data designed for high-frequency trading and derivatives applications.
• Chainlink DataLink: Delivers verified, institutional-grade data for onchain applications that demand precision and transparency.

With these tools, Aptos developers can now build advanced DeFi platforms that require accurate pricing, liquidity tracking, and funding rate calculations without relying on centralized data sources.

Aptos developers noted that these integrations enable next-generation DeFi use cases — particularly those that demand precision in derivatives pricing, lending markets, and automated asset management systems.

Decibel as the Flagship Partner

Decibel becomes the first protocol to fully utilize Chainlink’s new infrastructure on Aptos. The platform leverages Data Streams and DataLink to calculate mark prices and funding rates with greater precision.

These functions are essential for derivatives markets, where a fraction of a second in data delay can affect trading outcomes and liquidity management. By integrating Chainlink’s verified data, Decibel aims to enhance transparency and efficiency within Aptos-based trading environments.

Decibel’s testnet launch is planned for November, setting the stage for its role as a core component of Aptos’ DeFi ecosystem.

What This Means for Aptos and DeFi Developers

With Data Streams and DataLink now active on Aptos, developers can access real-time data suitable for:

• Decentralized derivatives
• Automated trading strategies
• Risk management systems
• Cross-chain asset pricing
• Institutional-grade DeFi products

The integration also aligns with Aptos’ design philosophy, emphasizing scalability, low latency, and developer accessibility through the Move programming language.

Together, Chainlink’s oracles and Aptos’ high-performance infrastructure provide a foundation for data-driven financial applications, bridging onchain execution with offchain information accuracy.

Technical Benefits in Focus

The technical aspects of this integration are practical and measurable:

• Reduced latency: Real-time data updates ensure price feeds remain accurate during high volatility.
• Improved reliability: DataLink’s aggregation process minimizes manipulation risk.
• Interoperability: CCIP support allows Aptos-based assets to move across 60+ chains.
• Security: Chainlink’s decentralized oracle network reduces single points of failure.

For developers, this means fewer dependencies on centralized APIs and a stronger base for scaling complex DeFi protocols.

Chainlink’s Growing Footprint on Aptos

This latest collaboration builds on a deeper relationship between Chainlink and the Aptos Foundation.

In September, the two organizations launched the Chainlink Cross-Chain Interoperability Protocol (CCIP) on the Aptos mainnet. That release marked the first time CCIP had been deployed on a Move-based blockchain, making Aptos interoperable with more than 60 other EVM and non-EVM networks.

The launch unlocked several cross-chain capabilities:

• Aave’s GHO stablecoin is now available as a Cross-Chain Token (CCT) on Aptos.
• Bedrock’s uniBTC and brBTC assets also went live, allowing users to transfer them through the CCIP-powered Interport app.

Through these developments, DeFi platforms such as Aave and asset issuers like Bedrock can expand into the Aptos network with minimal friction.

Built on Chainlink’s infrastructure, CCIP enables developers to deploy cross-chain applications in minutes while maintaining security and upgradeability.

Institutional Adoption and the SBI Digital Markets Connection

Chainlink’s integration momentum extends beyond Aptos. Recently, SBI Digital Markets (SBIDM) — the digital asset division of Japan’s ¥10+ trillion SBI Group — selected Chainlink CCIP as its exclusive interoperability layer for cross-chain transfers of tokenized assets.

The partnership enables:

• Private Transactions, keeping settlement data confidential.
• Automated Compliance Engine (ACE) integration for real-time policy enforcement.
• Tokenized securities and cash settlement across public and private blockchains.

SBIDM’s approach turns its digital asset platform into a full-service tokenized finance hub, linking custodians, asset managers, and regulated institutions through secure blockchain infrastructure.

This collaboration follows earlier work under Singapore’s Project Guardian, led by the Monetary Authority of Singapore, where Chainlink helped automate fund management alongside UBS Asset Management.

Conclusion

Chainlink’s integration with Aptos — anchored by Decibel as the flagship partner — establishes a data foundation for accurate pricing, efficient trading, and cross-chain liquidity.

From Data Streams to CCIP, Chainlink’s infrastructure is extending its reach across both retail and institutional layers of blockchain finance. Aptos, designed for scalability and speed, now benefits from a trusted data layer that powers the next wave of decentralized applications.

This partnership is about capabilities — specifically, the ability to deliver verified, low-latency, and interoperable data to developers and traders operating within one of the fastest-growing Layer 1 ecosystems.
