Transactions, Gas, and VTHO
Every action on the blockchain is a transaction. Transactions cost a small fee called gas, which is paid in VTHO on the VeChain network.
Wallet addresses
A wallet address is a unique identifier for your wallet, like a bank account number. On VeChain, addresses start with 0x followed by 40 characters. For example:
0x7a61c3a3B5F1E8C10d4C07eB20689b09a87539e2
Your address is safe to share, and it's how others send you tokens. Anyone can view your public balance and transaction history, but only you can move your funds using your private key (kept secure by your wallet).
If someone asks for your private key or backup phrase, that is a scam. Never share those.
Transactions
A transaction is any recorded action on the blockchain. Common types include:
- Receiving B3TR rewards after completing a challenge
- Sending tokens to another wallet address
- Voting in a VeBetterDAO allocation round
- Staking your B3TR tokens
- Swapping one token for another
Each transaction is permanent and public, and receives a unique transaction ID (or "tx hash") starting with 0x. Think of this as a receipt number you can use to look up or verify any transaction.
Gas and VTHO
Gas is the fee that covers the computing work needed to process a transaction. Think of it like a postage stamp: writing a letter is free, but delivering it costs a stamp.
On VeChain, gas fees are paid in VTHO (VeThor), a token separate from VET (VeChain's main token). This two-token design helps keep transaction costs stable regardless of VET's market price.
If you need VTHO for transactions, you can:
- Swap for it on decentralized exchanges within the VeChain ecosystem
- Receive it from another VeChain wallet, just like any other token
A typical VeChain transaction costs only a fraction of a cent in VTHO. You don't need much to stay active on the network.
Be cautious of anyone offering "free VTHO" through unofficial channels. Always use trusted platforms and the official VeWorld wallet.
Fee delegation on the Green Ambassador Challenge
The Green Ambassador Challenge uses a VeChain feature called fee delegation (VIP-191), which lets the platform pay gas fees on your behalf for most operations.
| Activity | Who pays the gas? |
|---|---|
| Completing challenges and earning rewards | Platform pays (fee delegation) |
| Receiving B3TR in your wallet | Platform pays (fee delegation) |
| Swapping tokens on VeBetterDAO | You pay (small VTHO fee) |
| Voting in allocation rounds | You pay (small VTHO fee) |
| Sending tokens to another wallet | You pay (small VTHO fee) |
Block explorers
A block explorer lets you search and inspect blockchain data. For VeChain, you can use VeChainStats or Insight. Paste any wallet address or transaction ID to verify rewards, check transaction status, or view token balances.
