Interoperability

Quick Answer

Interoperability is the ability of different blockchains to communicate and transfer assets between each other, enabling customers to pay from any chain with transparent cross-chain routing.

Full Definition

Interoperability is the ability of different blockchain networks to communicate, exchange data, and transfer assets between each other. Interoperability is achieved through bridges, cross-chain messaging protocols (LayerZero, Axelar, Wormhole), and standardised interfaces. For crypto payments, interoperability means a customer can pay from any supported chain and the merchant receives settlement on their preferred chain — the infrastructure handles the cross-chain routing transparently.
