The newly created TRON wallet accounts do not exist on the chain and require activation before they can be used.
There are two ways to activate accounts:
Send any amount of TRX or TRC-10 tokens from an existing account to the new account.
To activate a new account, an account creation fee of 1 TRX is charged. Additionally, if the sender of the above two transactions has enough Bandwidth obtained by staking TRX, the account creation will only consume bandwidth. Otherwise, 0.1 TRX will be burned to cover the bandwidth cost.
Transferring TRX or TRC-10 tokens to an inactive account address in a smart contract can also complete the account activation process.
In addition to the bandwidth and energy consumed by normal contract calls, this method will only require an additional 25,000 energy and will not incur the 1 TRX account creation fee or the 0.1 TRX bandwidth fee.
The above are the two activation methods provided by Tron official. We recommend using the first method as it is convenient and straightforward.
Please note that transferring TRC-20 tokens (e.g., USDT, USDC) does not activate the account.
When transferring on Bitcoin and Ethereum, BTC and ETH are used to pay transaction fees. However, when transferring on Tron, bandwidth and energy are consumed as transaction fees. When the available bandwidth or energy of the account is insufficient, TRX needs to be burned to pay for the corresponding bandwidth or energy.
Bandwidth
All types of transactions need to consume Bandwidth Points. The system provides each activated account with 600 bandwidth for free every day. Typically, an average TRX transaction requires about 300 bandwidth, while a TRC-20 token transaction requires more. 100 bandwidth equates to approximately 0.1 TRX.
Energy
The execution of each instruction of smart contract consume a certain amount of energy while running. Energy can be obtained by staking TRX, but there are no free energy distributed to every account. Generally, a single TRC-20 transfer requires approximately 345 bandwidth (about 0.345 TRX) and 64,285 (about 13.61 TRX) energy.
It is important to note that if an account does not have enough energy or bandwidth to pay the network fee, TRX will be automatically burned to offset the fee.
On the Tron blockchain, you can obtain energy and bandwidth through the following methods.
Staking TRX
You can choose to stake your TRX to obtain energy or bandwidth. Staking 2,000 TRX on Tronscan generates less than 30,000 energy.
Purchasing Energy
You can easily purchase energy for the TRON network on MPCVault. With just 6 TRX, you can buy 65,000 units of energy. Follow these steps to proceed:
Please ensure that your TRON wallet has sufficient TRX balance to complete the purchase transaction.
For a single TRC-20 transaction(e.g., send USDT on TRON Chain), the average network fee typically requires around 300+ bandwidth and 64,285 energy.
Note: If the recipient's wallet does not contain USDT, the energy required for the transaction will double.
Only perform the above actions on platforms that you trust.
We’re excited to announce our integration with the Story blockchain, now fully supported on MPCVault. Users can securely manage assets on Story through both our platform UI and API, with DeFi and transaction indexing support as well.
Story is a purpose-built Layer 1 blockchain designed to tokenize intellectual property into programmable digital assets. By embedding transparent licensing, automated attribution, and fair monetization, Story creates a secure foundation for AI-driven innovation and collaboration.

MPCVault App now supports managing vault members and viewing transaction policies. Authorized users can edit member privileges and review transaction policies directly from their mobile device — faster team coordination and improved transparency on the go.
MPCVault now allows you to modify asset approval amounts for EVM ERC-20 token transactions. During a pending signing request, you can easily adjust the authorized amount before signing, adding an extra layer of security control.
This setting is available on both the mobile app and web console.
The mnemonic phrase is one of the methods that can be used to recreate your personal key certificate. You can now import or export your mnemonic phrase in the app, with one-tap copy/paste to simplify the process.
For other ways to back up your personal key certificate, refer to this https://docs.mpcvault.com/product/how-to-back-up-your-personal-key-certificate/.
You can now top up your card using USDC on Solana, in addition to Ethereum and Polygon — choose from 3 networks that suit your needs. Once the funds are deposited, spend USDC directly at any merchant that accepts Visa worldwide.
For more information on how to top up, refer to https://docs.mpcvault.com/product/how-to-use-an-mpcvault-card/#depositing-funds.
We have added REST API support alongside our existing gRPC interface.
Both interfaces provide access to the same core functionality of MPCVault. Choose what works best for your use case. For API documentation on both interfaces, visit https://docs.mpcvault.com/api/api-reference/.
We’re excited to announce that MPCVault now supports Sonic SVM, the first Solana Virtual Machine (SVM) network extension built on Solana, focused on games and applications – built with Sonic HyperGrid, a framework for orchestrating optimistic Solana rollups.
This integration brings fast, scalable Solana-based gaming and app ecosystems to our secure, multi-sig, multi-chain wallet – empowering teams with easy dApp connections and advanced features like treasury management and customizable quorums.
Explore the future of Solana-native apps, now on MPCVault.

Try out the new Re-simulate button for signing requests, now available on both app and web.
This option appears only when a request is in a pending state, allowing users to rerun the transaction simulation before signing. This enables you to better review and verify transaction details, ensuring accuracy and preventing errors before finalizing any action.
