Delegate

Staking ATOM is a simple process. We will collect:

  • The delegator_address from which ATOM is being delegated, which will sign the transaction.
  • The validator_address to which ATOM is delegated.
  • The amount of ATOM to be delegated.
  • An optional memo to identify the transaction.
  • An optional gas_limit and gas_price in ATOM.

In the following guide we will illustrate how to stake ATOM.

Create New Staking Flow

To initiate the staking process, create a new flow with a POST request to /api/v1/flows.

URL

https://cosmos-slate.datahub.figment.io/api/v1/flows

Request

  • flow : object
    • network_code* : string Network this flow operates on (ex. cosmos).
    • chain_code* : string Chain this flow operates on (ex. testnet).
    • operation* : string The operation to perform (ex. staking).
{
  "flow": {
    "network_code": "cosmos",
    "chain_code": "testnet",
    "operation": "staking"
  }
}

Response

  • id : string ID of the flow.
  • operation : string The Staking API operation being performed by this flow.
  • state : string The current state of the flow.
  • actions : array It includes the name & inputs of all next possible actions.
    • create_delegate_tx : Use this action to generate a delegation transaction to stake your ATOM.
      • delegator_address : The address from which ATOM will be delegated.
      • validator_address : The validator address to which ATOM will be delegated.
      • amount : The amount of ATOM to be delegated.
      • memo : an optional message to record on-chain with your transaction.
      • gas_limit : the total amount of gas you're willing to let this transaction consume.
        • If you do not include this, we'll use a Cosmos library to select a good default for you.
      • gas_price : how many ATOM you're willing to pay per unit of gas consumed by this transaction.
        • If you do not include this, we'll use a Cosmos library to select a good default for you.
      • pubkey : Pubkey value will be retrieved from the chain but if you're using a fresh account (that does not have any outgoing activity) then this information is not available and it requires the user to pass it.
  • data : object Flow & transaction data.

Submit Signed Delegate Transaction for Broadcast

Before broadcasting the transaction, you must sign the transaction_payload you received in the previous step. After signing the transaction, send a PUT request to /api/v1/flows/[:flow_id]/next and the Staking API will broadcast the transaction to the network.

URL

Request

  • name* : sign_delegate_tx
  • inputs* : object
    • transaction_payload* : Signed transaction payload from the previous step's response.
    • signatures : array of object The signatures array can be used instead of sending a transaction payload when the signing keys are kept in a custodial solution, such as Fireblocks. Refer to the guide Signing Transactions with the Fireblocks API for details.
