Both positions must be from the same vault account (i.e. same withdrawal credentials). On chain, this translates into a consolidation transaction, where the source validator is consolidated into the destination validator. Supported chains: Ethereum (ETH) only. Endpoint Permission: Owner, Admin, Non-Signing Admin, Signer, Approver, Editor. **Note:** This endpoint is currently in beta and might be subject to changes. ## OpenAPI ````yaml https://docs.fireblocks.com/api/v1/swagger.yaml post /staking/chains/{chainDescriptor}/consolidate openapi: 3.0.0 info: title: Fireblocks API description: > Fireblocks provides a suite of applications to manage digital asset operations and a complete development platform to build your business on the blockchain. - Visit our website for more information: [Fireblocks Website](https://fireblocks.com) - Visit our developer docs: [Fireblocks DevPortal](https://developers.fireblocks.com) version: 1.6.2 contact: email: developers@fireblocks.com servers: - url: https://api.fireblocks.io/v1 description: Fireblocks Production Environment Base URL - url: https://sandbox-api.fireblocks.io/v1 description: Fireblocks Sandbox Environment Base URL security: [] paths: /staking/chains/{chainDescriptor}/consolidate: post: tags: - Staking summary: Consolidate staking positions (ETH validator consolidation) description: >- Consolidates the source staking position into the destination, merging the balance into the destination and closing the source position once complete.
