Staking MATIC tokens happens on the Ethereum network (not the Polygon network), and requires two steps:

Allowance Transaction: This approves sending a specific amount of MATIC tokens to a staking contract on Ethereum.
Delegation Transaction: This delegates MATIC to a specific validator via its associated smart contract. Figment's validator contract address is 0xb929B89153fC2eEd442e81E5A1add4e2fa39028f.

NOTE

📘
Before using this flow, please ensure that your MATIC tokens are on Ethereum mainnet or testnet. This may require you to withdraw your MATIC tokens from Polygon to Ethereum via the Polygon bridge.
There is a step-by-step guide for the withdrawal process available on the Polygon docs: https://wiki.polygon.technology/docs/develop/wallets/polygon-web-wallet/web-wallet-v3-guide/#step-by-step-guide-2.
For mainnet the contract address of the MATIC token is 0x7D1AfA7B718fb893dB30A3aBc0Cfc608AaCfeBB0 — Etherscan - Mainnet MATIC Token
For testnet the contract address of the MATIC token is 0x499d11E0b6eAC7c0593d8Fb292DCBbF815Fb29Ae — Etherscan - Testnet MATIC Token

In the following guide we will illustrate how to stake MATIC tokens.

Create New Staking Flow

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

Request

flow : object
- network_code* : string Network on which this flow operates (ex. polygon).
- chain_code* : string Chain on which this flow operates (ex. mainnet , testnet).
- operation* : string The operation to perform (ex. staking).

{
  "flow": {
    "network_code": "polygon",
    "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.
- assign_staking_data : Provide the funding address, validator contract address, and amount of tokens to be staked. The Staking API will check on-chain to determine if an allowance transaction is needed.
  - delegator_address : The main wallet from which MATIC will originate.
  - validator_address : The validator smart contract address for delegation.
  - amount : The number of MATIC tokens to be delegated.
  - minimum_shares_to_mint : The minimum number of shares of the delegation pool to be minted. If the exchange rate results in fewer shares being minted, the transaction will fail.
  - max_slippage_percentage : The maximum slippage you are willing to accept.
data : object Flow & transaction data.

Submit Signed Allowance 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 Polygon network.

Request

name* : sign_allowance_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.
