Highly secure and flexible infrastructure

Reliable, tamper-proof network

Use decentralization, trusted nodes, premium data, and cryptographic proofs to connect highly accurate and available data/APIs to any smart contract.

Seamless connection to any API

Build on a flexible framework that can retrieve data from any API, connect with existing systems, and integrate with any current or future blockchain.

Proven, ready-made solutions

Integrate pre-built, time-tested oracle solutions that already secure tens of billions in smart contract value for market-leading decentralized applications.

Secure off-chain computation

Use a decentralized network of Chainlink Keeper nodes to automate contracts, mitigating risk of manual interventions and centralized servers.

What is Cryptobold?

The industry standard Oracle Network

Chainlink greatly expands the capabilities of smart contracts by enabling access to real-world data and off-chain computation while maintaining the security and reliability guarantees inherent to blockchain technology.
