​
Parameters

  • owner_address — address of the witness account updating the brokerage. Use base58 with visible: true, or hex with visible: false.
  • brokerage — new brokerage percentage (0–100); lower values share more rewards with voters.
  • visible — optional boolean. When true, addresses are base58; when false, hex. Default is true.

​
Response

  • visible — boolean indicating whether addresses are in visible format
  • txID — unique transaction ID for the brokerage update transaction
  • raw_data — raw transaction data containing:
    • contract — array with brokerage update contract details
    • ref_block_bytes — reference block bytes for transaction validation
    • ref_block_hash — hash of the reference block
    • expiration — transaction expiration timestamp
    • timestamp — transaction creation timestamp
  • raw_data_hex — complete transaction data encoded in hexadecimal format

​
Use case

The wallet/updatebrokerage method is used for:
  • Adjusting witness reward sharing policies to attract more voters.
  • Setting competitive brokerage rates compared to other witnesses.
  • Implementing dynamic reward sharing strategies based on market conditions.
  • Managing witness economics to balance profitability and voter incentives.
Only registered witnesses can update their brokerage rate. The brokerage rate determines what percentage of block rewards the witness keeps (0-100%). A rate of 20% means the witness keeps 20% and shares 80% with voters. Changes may take effect after the next maintenance period.

curl --request POST \
  --url 'https://tron-mainnet.core.chainstack.com/95e61622bf6a8af293978377718e3b77/wallet/updateBrokerage' \

  --data '{
  "owner_address": "THPvaUhoh2Qn2y9THCZML3H815hhFhn5YC",
  "brokerage": 15,
  "visible": true
}'
common validation errors:
  • No permission — the owner_address is not a registered witness.
  • Account […] does not exist — ensure the address is activated and the format matches visible.
  • Rate bounds — brokerage must be between 0 and 100.
  • Not existed witness — register the witness first via wallet/createwitness and wait until it is recognized on-chain.
