Cosmos / Transfer

Transferring ATOM is a simple process. We will collect:

• The account from which ATOM to be transferred, which will sign the transaction.
• The address to which ATOM is transferred.
• Amount of ATOM to be transferred.
• An optional memo.
• An optional gas_limit and gas_price, denominated in ATOM.

Follow the steps in this section for the details on this process.

Flow Diagram

Below is a complete diagram for the Cosmos Transfer flow:

Actions

• Create New Transfer Flow
• Submit Transfer Data
• Submit Signed Transfer Transaction for Broadcast
• Get Transfer Flow Status

---

Create New Transfer Flow

To initiate the transfer 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. transfer).

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_transfer_tx — Use this action to transfer ATOM.
    • from_account_address : The address from which ATOM will be transferred.
    • to_account_address : The address to which ATOM will be transferred.
    • amount : The amount of ATOM to be transferred.
    • memo : an optional message to record on-chain with your transfer.
    • 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 Transfer Data

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

URL

https://cosmos-slate.datahub.figment.io/api/v1/flows/[:flow_id]/next

After collecting the required inputs as mentioned below, send a PUT request to /api/v1/flows/[:flow_id]/next to proceed to the next step.

Request

• name* : create_transfer_tx.
• inputs* : object
  • from_account_address* : string The address from which ATOM will be transferred.
  • to_account_address* : string The address to which ATOM will be transferred.
  • amount* : number The amount of ATOM to be transferred.
  • 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.
  • gas_price : number How many ATOM you're willing to pay per unit of gas consumed by this transaction.
  • pubkey : string Required only if you're using a fresh account (that does not have any outgoing activity) else optional.

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.
  • refresh_transfer_tx : If you need to get a fresh version of the transaction payload (i.e., the nonce has increased).
  • sign_transfer_tx : Submit a signed transaction payload or an array of signatures to continue the flow. Refer to the guides Signing Transactions with Figment's npm Package and Signing Transactions with the Fireblocks API for details.
  • confirm_transfer_tx_by_hash : Submit a previously completed transaction hash to continue the flow. Refer to the guide Advance Flows Using a Transaction Hash.
• data : object Flow & transaction data.

Submit Signed Transfer 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

https://cosmos-slate.datahub.figment.io/api/v1/flows/[:flow_id]/next

Request

• name* : sign_transfer_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.

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.
  • transfer_tx_broadcasting : Transaction has been broadcast and is waiting for confirmation.
  • completed : Transaction has been confirmed and the transfer is complete.
• actions : array It includes the name & inputs of all next possible actions.
• data : object Flow & transaction data.
