Definition
A bridge aggregator is a coordination concept in blockchain interoperability that queries and combines multiple independent cross-chain bridges to determine a preferred route for transferring value or data between networks. It abstracts individual bridge characteristics behind a unified interface, enabling selection among heterogeneous bridging options based on predefined criteria such as supported chains, assets, and security assumptions, without being tied to a single underlying bridging mechanism.
In Simple Terms
A bridge aggregator is a concept for organizing and choosing between many different blockchain bridges through one combined view. Instead of focusing on a single bridge, it treats many bridges as options in a larger set and selects one according to preset rules, while hiding most of the technical differences between those bridges.
Context and Usage
The term bridge aggregator appears in discussions about cross-chain design, interoperability architectures, and multi-chain liquidity coordination. It is referenced when describing systems that sit conceptually above individual bridges, treating them as interchangeable components in a broader connectivity layer. Bridge aggregators are often mentioned in relation to on-chain routing logic, external oracle inputs, and security models that depend on the properties of the underlying bridges.
