> **NOTE: About chain selectors**
>
> A **chain selector** is Chainlink's unique numeric identifier for each blockchain network. Unlike chain IDs, chain
> selectors are globally unique across all supported networks. CRE Connect uses chain selectors — not chain IDs — to
> identify the chain a [Watcher](/crec/concepts/watchers), [Smart Account](/crec/concepts/smart-accounts), or
> [Operation](/crec/concepts/operations) is bound to.
