getContractSalt

suspend fun getContractSalt(credentialId: ByteArray): ByteArray

Computes the contract salt from a WebAuthn credential ID.

The salt is used as part of the contract address derivation process to ensure each credential ID results in a unique contract address. This is computed as the SHA-256 hash of the credential ID.

Return

SHA-256 hash of the credential ID (32 bytes)

Example:

val credentialId = ... // from WebAuthn registration
val salt = SmartAccountUtils.getContractSalt(credentialId)

Parameters

credentialId

WebAuthn credential ID
