Resource Delegation

hashtag
Overview

Resource delegation allows one TRON account to provide Bandwidth or Energy to another account without transferring TRX. This is a core feature of Stake 2.0 and the mechanism that powers services like TronZap.

How Delegation Works

  • A staker locks TRX via Stake 2.0 to obtain resources

  • Instead of using those resources themselves, the staker can delegate them to any other TRON address

  • The recipient account can then use the delegated resources for transactions

  • The staker retains ownership of the staked TRX — only the resource usage rights are transferred

  • Delegation is performed via the delegateresource system contract

  • To reclaim delegated resources, the staker calls undelegateresource

hashtag
Delegation Parameters

  • Resource type: BANDWIDTH or ENERGY

  • Receiver address: the TRON address that will receive the resources

  • Amount: specified in TRX (the system converts this to the corresponding resource amount)

  • Lock period (optional): if set, the delegation cannot be revoked for the specified duration

  • When the lock period expires, the staker can undelegate at any time

hashtag
Use Cases

  • Energy rental services (like TronZap): stake large pools of TRX, delegate Energy to paying users for a set duration, then reclaim it

  • Subsidizing user transactions: DApps can delegate resources to their users so they don't need to hold TRX

  • Team/organization resource sharing: a treasury account stakes TRX and delegates resources to operational wallets

How TronZap Uses Delegation

  • TronZap maintains a pool of staked TRX generating Energy

  • When a user pays for energy rental, TronZap automatically delegates the requested amount of Energy to the user's address

  • The delegation typically lasts for 1 hour (for direct recharge) or as specified by the subscription

  • After the period expires, the Energy is reclaimed and returned to the pool

  • This model is more cost-effective for users than staking TRX themselves, because: (a) no capital lock-up, (b) no 14-day unstaking wait, (c) pay only for what you need
