# A secure interoperability protocol

#### Defense-in-depth security

Powered by Chainlink’s industry-standard oracle networks. GRE also features additional layers of protection via the Risk Management Network and transfer rate limits.

#### Simplified token transfers

Seamlessly scale your userbase and benefit from enhanced token composability by securely transferring tokens across chains in a fraction of the time it would take to build a custom solution.

#### Reliable transaction execution

A transaction price is quoted on the source chain via a gas-locked fee payment mechanism that confirms execution regardless of destination chain gas spikes and network congestion.

#### Seamless integration

A single, easy-to-integrate interface for a unified cross-chain developer experience. Simply integrate GRE onchain and start building secure cross-chain applications.

#### Scalable architecture

Eliminates the need for developers to write custom code for chain-specific integrations, while users can interact with any blockchain via a single interface.

#### Extendable and future-proof

GRE will continue to be updated over time to support new blockchains, enhanced functionalities, and additional defense-in-depth approaches.
