TRON API method that updates the consume user resource percentage setting for a smart contract. This setting determines what percentage of the contract caller’s resources (bandwidth and energy) should be consumed when executing the contract.

​
Parameters

  • owner_address — address of the contract owner who can update settings
  • contract_address — address of the smart contract to update settings for
  • consume_user_resource_percent — percentage (0–100) of caller’s resources to consume
  • visible — boolean indicating whether to use visible (Base58) address format instead of hex

​
Response

  • visible — boolean indicating whether addresses are in visible format
  • txID — unique transaction ID for the setting update transaction
  • raw_data — raw transaction data containing:
    • contract — array with contract update 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/updatesetting method is used for:
  • Adjusting resource consumption patterns for smart contract execution.
  • Optimizing contract costs by controlling user vs contract owner resource usage.
  • Managing energy and bandwidth allocation between contract and users.
  • Implementing different pricing models for contract interactions.
  • Fine-tuning contract economics and user experience trade-offs.
  • Setting up contracts to be more or less resource-friendly to callers.
Only the contract owner can update the consume user resource percentage. Setting this to 100 means all resources come from the caller, while 0 means all resources come from the contract owner. The default is typically 100.

1

verify owner account exists

Shell
curl --request POST \
  --url 'https://tron-mainnet.core.chainstack.com/95e61622bf6a8af293978377718e3b77/wallet/getaccount' \
  --header 'Content-Type: application/json' \
  --data '{ "address": "THPvaUhoh2Qn2y9THCZML3H815hhFhn5YC", "visible": true }'
2

confirm contract owner

Use wallet/getcontract with a hex address to retrieve origin_address and ensure it matches owner_address (converted to hex if needed).
Shell
curl --request POST \
  --url 'https://tron-mainnet.core.chainstack.com/95e61622bf6a8af293978377718e3b77/wallet/getcontract' \
  --header 'Content-Type: application/json' \
  --data '{ "value": "41a614f803b6fd780986a42c78ec9c7f77e6ded13c" }'
common validation errors:
  • Account [41…] does not exist — the payer address is not activated or visible does not match the provided address format.
  • No permission — the owner_address is not the contract owner (origin_address).
  • Contract not found — verify the contract address and format.
