To unstake ATOM tokens, you will need:

The delegator_address from which ATOM was delegated, which will sign the transaction.
The validator_address from which ATOM is being undelegated.
The amount of ATOM to be undelegated.
An optional memo to identify the transaction.
An optional gas_limit and gas_price in ATOM.
The pubkey (public key) of the delegator_address.

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

Create New Unstaking Flow

To initiate the unstaking process with Staking API, create a new flow with POST /flows.

URL

https://api.figment.io/flows

Request

protocol* : string Protocol this flow operates on (ex. cosmos).
network* : string Network this flow operates on (ex. testnet).
operation* : string The operation to perform (ex. unstaking).

{
  "protocol": "cosmos",
  "network": "testnet",
  "operation": "unstaking"
}

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_undelegate_tx : Use this action to generate an undelegation transaction to unstake your ATOM.
  - delegator_address : The address from which ATOM was delegated.
  - validator_address : The validator address from which ATOM will be undelegated.
  - amount : The amount of ATOM to be undelegated.
  - 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 Undelegate Data

After creating the new undelegation flow, we need to submit the undelegate data.

After collecting the required inputs as mentioned below, send a PUT request to /flows/[:flow_id]/next to proceed to the next step.

URL

- delegator_address* : string The address from which ATOM was delegated.
- validator_address* : string The validator address from which ATOM will be undelegated.
- amount* : number The amount of ATOM to be undelegated.
- memo : string A message to record on-chain with your transfer.
- gas_limit : number The total amount of gas you're willing to let this transaction consume.

Submit Signed Undelegate 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 /flows/[:flow_id]/next and the Staking API will broadcast the transaction to the network.

URL

https://api.figment.io/flows/[:flow_id]/next

Request

name* : sign_undelegate_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.
