The Staking API's staking proxy flow for Polkadot will walk your application through the process of adding proxy rights to another account.
Proxy On-Chain deposit
Proxies require deposits in the native currency (i.e. DOT) to be created. The deposit is required because adding a proxy requires some storage space on-chain, which must be replicated across every peer in the network.
Once the proxy is removed, both the storage space and the deposited amount are returned.
The required deposit amount for n proxies is equal to:
ProxyDepositBase + ProxyDepositFactor
Where the ProxyDepositBase is the required amount to be reserved for an account to have a proxy list (creates one new item in storage). For every proxy the account has, an additional amount defined by the ProxyDepositFactor is reserved as well.
The ProxyDepositBase is 20.008 DOT and the ProxyDepositFactor is 0.033 DOT.
In the following guide we will illustrate how to add a proxy account.
Create New Add Staking Proxy Flow
To add a staking proxy, create a new flow with a POST
request to /api/v1/flows
.

Submit Signed Add Proxy Transaction for Broadcast
Before broadcasting the transaction, you must sign the transaction_payload
you received in the previous step. After signing the transaction, you will PUT /api/v1/flows/[:flow_id]/next
(as always!) and the Staking API will broadcast the transaction to the Polkadot network.
