How TON Wallets Work

On TON, every wallet is a smart contract. Your first transaction deploys this contract, requiring a small TON payment. MPCVault displays addresses in “UQ” format.

Transaction Fees

TON fees consist of multiple components:
Fee TypeDescription
StorageCost for storing your wallet contract on-chain
ForwardFees for sending messages between contracts
ActionFee for executing the transaction
ComputationCost for running contract code
TON fees cannot be customized. MPCVault does not charge additional fees.

Usage Tips

  • First transaction costs extra to deploy the wallet contract (one-time)
  • Every transaction incurs storage fees
  • When sending to exchanges, always include the required Comment (memo/tag)

Comment vs Transaction Notes

Transaction NotesPrivate (MPCVault only)Internal tracking for your team
When depositing to an exchange, enter the memo/tag in the Comment field, not Transaction Notes. If you forget, contact the exchange support—your funds are safe as long as the address is correct.
