Keystore API

Because the node operator has access to your plain-text password, you should only create a keystore user on a node that you operate. If that node is breached, you could lose all your tokens. Keystore APIs are not recommended for use on Mainnet.

Every node has a built-in keystore. Clients create users on the keystore, which act as identities to be used when interacting with blockchains. A keystore exists at the node level, so if you create a user on a node it exists only on that node. However, users may be imported and exported using this API.

For validation and cross-chain transfer on the Mainnet, you should issue transactions through AvalancheJS. That way control keys for your funds won't be stored on the node, which significantly lowers the risk should a computer running a node be compromised. See following docs for details:

Transfer AVAX Tokens Between Chains:
- C-Chain: export and import
- P-Chain: export and import
- X-Chain: export and import
Add a Node to the Validator Set

Note

This API set is for a specific node, it is unavailable on the public server.

Format

This API uses the json 2.0 API format. For more information on making JSON RPC calls, see here.

Endpoint

Methods

`keystore.createUser`

Create a new user with the specified username and password.
