Unified API + Babylon Integration Workflow

In the following guide, the integration process for the babylon-btc chain is covered. The Babylon integration aligns with the general Unified API process but with network-specific parameters.

Get an authentication token to start using the Unified API.

Request examples are provided using cURL.

To check the integration guides for other chains, refer to the Networks section.

Key Babylon-specific details

  • chain — always set to babylon-btc for Babylon-related requests.
  • network — environment in which the transaction is processed (mainnet or testnet).
  • stakerAddress — account address initiating staking, unstaking or withdrawal transactions.
  • amount — amount of tokens in SATOSHI.

Staking Flow

1. Create Staking Request

Send a POST request to /api/v1/unified/staking/stake.

Example request (for testnet network):

curl --request POST \
     --url https://api-test.p2p.org/api/v1/unified/staking/stake \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <token>' \
     --data '{
    "chain": "babylon-btc",
    "network": "testnet",
    "stakerAddress": "tb1paty3ht42hj74lfq7608v6uhmlry6yn4hpxefa32ucqyzldzaqrks3juxrs",
    "amount": "1",
    "extra": {
      "stakerPublicKey": "0384b203765094496a32cf8817fba045d0bc8a4dab3256551c41f05a8536141c98"
    }
}'
  • chain — blockchain network, always set to babylon-btc for Babylon-related requests.
  • network — environment in which the transaction is processed (mainnet or testnet).
