# Chains

Chains represent the supported blockchain networks that Pareto interacts with. These include the networks where vaults are deployed, where user interactions occur, and where transactions are tracked.

## Structure

Each chain object includes:

* `_id` *(string)* — Unique identifier for the chain
* `name` *(string)* — Human-readable name of the blockchain (e.g., "Ethereum")
* `chainId` *(string)* — Network ID used internally by Pareto
* `nativeToken` *(string)* — Symbol of the native currency (e.g., ETH, MATIC)
* `explorerUrl` *(string)* — Block explorer base URL for linking transactions or accounts
* `icon` *(string)* — Optional icon URL
* `createdAt`, `updatedAt` *(string)* — ISO timestamps (UTC Unix time)
