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.
