To facilitate clients in quickly and conveniently integrating the system, ChainUp has outlined the core processes based on past client integration experiences, focusing on the integration solutions for [Get Receiving(Deposit) Address] , [User Receiving(Deposit)] and [User Transfer (Withdrawal)]. The details are as follows:

​
Get Receiving Address

  • Create a wallet /api/mpc/sub_wallet/create
  • Create a coin address for the wallet /api/mpc/sub_wallet/create/address
  • ChainUp callbacks Co-Signer for signing, and Co-Signer collaborates with ChainUp node to complete the signing
  • Successfully signed, return the address created for the coin
Addresses support two types: system addresses and user addresses. The system address is used for auto sweep or is used as change address, cannot be assigned to users.

​
User Receiving (Deposit)

  • Users complete registration within the client system.
  • When users view the coin receiving address in the frontend, the client system assigns a coin address to the user.
  • Users deposits assets to the assigned address.
  • ChainUp monitors the blockchain address for incoming transactions. After detecting a deposit, ChainUp notifies the client’s business system of the receiving notification (the client’s system actively retrieves /api/mpc/billing/sync_deposit_list).
  • The client obtains the current block height of the corresponding blockchain for the coin (/api/mpc/chain_height).
  • The client system credits the user’s account after confirming the required number of secure confirmations.
  • User receives the coin (deposits successful).

​
User Transfer (Withdrawal)

  • Users initiate a transfer in the client system.
  • After the client system approves the Transfer, it initiates a Transfer request to the ChainUp system via API /api/mpc/billing/withdraw.
  • Co-Signer periodically retrieves withdrawal transactions. If Co-Signer has configured a callback program, it confirms with the client’s business system. If Co-Signer has configured signature verification, it verifies the signature and collaborates with the ChainUp node to sign.
  • Once signed, ChainUp broadcasts the transaction to the blockchain and monitors its status.
Supported blockchains for acceleration can be obtained through the API /api/mpc/wallet/open_coin.
  • After blockchain confirmation, ChainUp notifies the client’s business system of the transfer notification (the client’s system actively retrieves /api/mpc/billing/sync_withdraw_list).
  • The client system updates the order status.
  • User transfer out successful.
