Smart account providers - Rhinestone

The account provider determines the contract implementation, deployment address, and provider-specific configuration. It does not replace your signer choice.

Recommended default

Use Nexus unless you need compatibility with another account ecosystem. @rhinestone/sdk 2.16.1 selects Nexus when you omit account.type.

Supported choices

Provider	Choose it when
Nexus	You are creating a new account and do not need another provider’s compatibility. It is the SDK default and the supported EIP-7702 implementation.
Safe	You need the Safe account ecosystem or must reproduce a Safe-based account configuration.
Kernel	You need compatibility with a Kernel account configuration.
Startale	You need compatibility with a Startale account configuration.
HCA	You need Rhinestone’s specialized HCA account with ENS ownership. HCA does not support recovery, session keys, or additional modules.

Choose bring your own account if the account already exists and you need to preserve its address and deployment data. Choose a plain EOA when you do not need a smart account.

Changing the provider, version, salt, nonce, or owner configuration can change a counterfactual account address. Preserve the complete configuration you use in production.
