How To Delegate Cpu Resource


Delegate CPU bandwidth for an account or application.

Before you begin

Make sure you meet the following requirements:

  • Familiarize with the cleos system delegatebw command and its parameters.
  • Install the currently supported version of cleos.

cleos is bundled with the EOSIO software. Installing EOSIO will also install cleos.

  • Ensure the reference system contracts from eosio.contracts repository is deployed and used to manage system resources.
  • Understand what an account is and its role in the blockchain.
  • Understand CPU bandwidth in an EOSIO blockchain.
  • Understand NET bandwidth in an EOSIO blockchain.


Perform the step below:

Delegate CPU bandwidth from a source account to a receiver account:

cleos system delegatebw <from> <receiver> <stake_net_quantity> <stake_cpu_quantity>

Where from is the account to delegate bandwidth from, receiver is the account to receive the delegated bandwidth, and stake_net_quantity and/or stake_cpu_quantity is the amount of tokens to stake for network (NET) bandwidth and/or CPU bandwidth, respectively.

Some examples are provided below:

  • Delegate 0.01 SYS CPU bandwidth from bob to alice:

Example Output

cleos system delegatebw bob alice "0 SYS" "0.01 SYS"
