Purpose
The W5 (Wallet v5) standard is the next-generation smart contract architecture for the TON blockchain, co-developed by Tonkeeper and the TON Core team. Its primary purpose is to eliminate the technical friction of the previous V4 standard by introducing native gasless transactions and flexible extensibility. In 2026, W5 allows your wallet to behave more like a programmable account than a simple address. It enables you to pay network fees using the tokens you are actually sending (like USDT or NOT) and supports advanced parallel processing, allowing the wallet to handle hundreds of requests in a single signature.
Step-by-Step
1. Check Your Current Version
Open Tonkeeper and tap on your wallet name at the top of the screen. If you see "V4R2" next to your address, you are on the older standard. W5 is a distinct contract with its own unique address, even though it uses the same recovery phrase.
2. Enable W5 in Settings
Go to Settings and look for the "W5 Wallet" or "Wallet Version" section. Tap on "Add W5". Tonkeeper will generate your new W5 address instantly. You can now toggle between your V4 and W5 accounts within the same app interface.
3. Transfer Assets to the New Address
Because W5 has a different public address than V4, you must manually move your funds. Copy your new W5 address, switch back to your V4 account, and send your Toncoin and tokens to the W5 address. Note: You will need a small amount of TON in your V4 wallet to pay for this one-time migration.
4. Set Up Gasless Permissions
Once your tokens are in the W5 wallet, try sending USDT. On the final confirmation screen, you will now see an option to "Pay fee in USDT." Select this to experience the core benefit of the W5 standard.
5. Reconnect dApps
Since W5 is a new address, you must reconnect to any dApps (like STON.fi or DeDust) using the W5 account to ensure the smart contracts recognize your new identity and its gasless capabilities.
Use Case
- The Massive NFT Airdrop:
- A creator wants to send 200 NFTs to different winners. Under the old V4 standard, this would require 200 separate transactions and signatures. With W5, the creator can use the Multi-Send feature to bundle all 200 transfers into a single signed message, saving time and reducing cumulative gas costs by roughly 25%.
- The "Pure" Stablecoin User:
- A user receives their salary in USDT and only wants to use the blockchain for payments. They don't want to buy Toncoin or deal with price volatility. By using a W5 Wallet, they can live entirely in USDT—sending payments and paying all network fees using their USDT balance through the W5 relay service.
Best Results
For the best results in 2026, use W5 for all stablecoin management and high-frequency trading. W5 is approximately 25% more gas-efficient than V4 for standard operations. If you are a developer or power user, leverage the W5 Extension interface; this allows you to add features like 2-Factor Authentication (2FA) or "subscription" logic directly to your wallet contract. However, keep a small V4 balance active if you interact with legacy dApps that have not yet updated their front-ends to support the Wallet v5 address format.
FAQ
- Does W5 change my recovery phrase?
- No. Your 24-word phrase remains the same. The W5 standard simply derives a new address from that same phrase using a different derivation path or contract logic.
- Why is my W5 address different from my V4 address?
- In TON, your address is the hash of your wallet's smart contract code and data. Because W5 uses a completely new and more powerful smart contract, the resulting address is different.
- Are gasless fees more expensive?
- Slightly. When you pay fees in tokens like USDT, the relay service adds a small convenience premium to cover the conversion and the risk of price volatility. Paying in native Toncoin is always the cheapest option.
Disclaimer
The W5 standard is a powerful tool, but migrating to it requires manual asset transfers. Ensure you are sending funds to your own verified W5 address. While W5 supports gasless features, the availability of specific tokens for fee payment depends on third-party relayers and market liquidity.
