Relayers serve as essential intermediaries in blockchain networks, facilitating cross-chain communication and data transfer. They act as bridges between different blockchain networks, enabling them to interact and share information securely.

At their core, relayers perform three key functions:

• Message verification from source chains
• Data transmission across networks
• Transaction execution on destination chains

These specialized nodes monitor events on one blockchain and relay relevant information to another, maintaining the integrity and security of cross-chain transactions. This process allows users to:

• Transfer assets between different blockchain networks
• Execute smart contracts across chains
• Access services on multiple networks seamlessly

Relayers achieve this through standardized protocols and consensus mechanisms, ensuring that information transmitted between chains remains authentic and tamper-proof. They typically operate using:

• Cryptographic proofs
• Smart contract verification
• Secure messaging protocols

The presence of relayers enables blockchain interoperability, a crucial feature for the widespread adoption of decentralized technologies. This infrastructure supports various use cases, including:

• Cross-chain token swaps
• Multi-chain DeFi applications
• Inter-blockchain communication protocols

For users, this means access to a broader range of services and improved flexibility in managing digital assets across different blockchain ecosystems.
