Legacy Staking API (Flows)

ETH Aggregated Staking and Unstaking

We're deprecating our ETH Aggregated Staking and ETH Aggregated Unstaking flows. All features are available through our other Ethereum RESTful endpoints:

SOL Staking Flows

SOL flows are being replaces by the following RESTful endpoints:

  • Besides Rewards, POST requests will create the appropriate unsigned transaction. After signing, call Broadcast
  • After broadcasting, Tx Status returns the status of your transaction
  • Stakes will return statuses and balances of each of your stake accounts
  • Flows:
    • Staking: create_stake_account and delegate transactions are now combined into a single endpoint, Stake
    • MergeStakeAccount: Replaced by Merge
    • SplitStakeAccount: Replaced by Split
    • Unstaking: create_deactivate_tx maps to Undelegate, and create_withdraw_tx maps to Withdraw

Staking Flows (Create)

  • The endpoint URL has changed:
    • V1 URL: https://{network}-slate.datahub.figment.io/api/v1/flows
    • V2 URL: https://api.figment.io/flows

Staking Flows (Next)

  • The endpoint URL has changed:
    • V1 URL: https://{network}-slate.datahub.figment.io/api/v1/flows/[:flow_id]/next
    • V2 URL: https://api.figment.io/flows/[:flow_id]/next

Polkadot Proxy

DOT Add Nomination Proxy

  • The endpoint URL has changed:
    • V1 URL: https://hubble.figment.io/api/v1/prime/polkadot/nomination_proxy
    • V2 URL: https://api.figment.io/polkadot/nomination_proxy

DOT Revoke Nomination Proxy

  • The endpoint URL has changed:
    • V1 URL: https://hubble.figment.io/api/v1/prime/polkadot/nomination_proxy/revoke_proxy
    • V2 URL: https://api.figment.io/polkadot/nomination_proxy/revoke_proxy

ETH Validators API

Provision Validators

  • V1 Endpoint -> V2 Endpoint
  • The URL has changed:
    • V1 URL: https://hubble.figment.io/api/v1/prime/eth2_staking/provision
    • V2 URL: https://api.figment.io/ethereum/validators
  • Before: /provision allowed you to create validator public keys in an asynchronous way: it didn’t return the validators data in the response and you needed to poll Get Validators and then call Build Funding Transaction to get a staking transaction for validators.
  • Now: Creating validators and generating a staking transaction to fund them are now merged into one synchronous endpoint: Create Validators.
  • The parameter eth2_network_name is renamed to network

Build Funding Transaction

  • V1 Endpoint
  • This endpoint is not present in the API V2.
  • Before: This endpoint allowed you to get a staking transaction to fund N validators that had previously been provisionedusing the Provision Validators endpoint. This was a two step process
  • Now: Creating validators and generating a staking transaction to fund them are now merged into one synchronous endpoint: Create Validators.

ETH Get Validators

  • The URL has changed:
    • V1 URL: https://hubble.figment.io/api/v1/prime/eth2_staking/validators
    • V2 URL: https://api.figment.io/ethereum/validators
  • The parameter eth2_network_name is now network
  • The response field presigned_exit_transaction is now an object called exit_message
  • Request additional metadata (status history, deposit data, exit message, etc) is now handled with the include_fields parameter.
  • Validator metadata in the repsonse is now nested directly in the parent data object instead of data.attributes
  • Response field meta object in V2 gives you pagination info
