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 Type | Description |
|---|
| Storage | Cost for storing your wallet contract on-chain |
| Forward | Fees for sending messages between contracts |
| Action | Fee for executing the transaction |
| Computation | Cost 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)
| Field | Visibility | Purpose |
|---|
| Comment | Public (on-chain) | Required by exchanges to identify deposits |
| Transaction Notes | Private (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.
