Staking NEAR is a simple process. We will collect:

  • The delegating address
  • The signing public key
  • The validator address
  • The amount of NEAR to be staked
  • Optionally, a max gas amount (upper limit of the transaction fee to be paid)

Once the delegating transaction is confirmed on-chain, the delegation will immediately be active and earning staking rewards.

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

Create New Staking Flow

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

URL

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

Request

  • flow : object
    • network_code* : string Network this flow operates on (ex. near).
    • chain_code* : string Chain this flow operates on (ex. mainnet).
    • operation* : string The operation to perform (ex. staking).
{
  "flow": {
    "network_code": "near",
    "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 NEAR.
      • validator_address : Figment validator address.
      • delegator_address : The delegating address.
      • delegator_pubkey : The public key of the signing account. Must start with ed25519:.
      • amount : The amount of NEAR to be delegated.
      • max_gas : Adjust if you wish to limit the possible transaction fee.
  • 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 with the signed payload. The Staking API will broadcast the transaction to the Ethereum network.

Request

  • name* : string Name of the action to execute.
  • 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.
