PulseChain gas fees in plain words
Every PulseChain transaction pays a small fee in PLS, the chain's own coin. PlsLens shows what common actions cost right now, and why.
The live page shows Slow, Normal and Fast costs for each action, in dollars and PLS, updated every 30 seconds.
What is gas on PulseChain?
- Gas is how much work a transaction takes. A plain transfer takes little. A swap takes more.
- Fee = gas used × gas price.
- The fee is paid in PLS. It is paid even if the transaction fails, because the work was still done.
What is a beat?
PlsLens calls the unit of the gas price a beat. 1 beat is one billionth of a PLS. Wallets and Ethereum call the same unit gwei.
How much gas does a transfer, a swap or a HEX stake use?
These are the amounts PlsLens uses to price each action. Real amounts vary a little by app.
| Action | Gas, about |
|---|---|
| Send PLS | 21,000 |
| Approve a token | 46,000 |
| Start a HEX stake | 70,000–95,000 |
| Bridge to Ethereum (PulseChain side) | 120,000 |
| Swap on PulseX | 150,000 |
| Add liquidity on PulseX | 200,000 |
To turn gas into PLS: gas × price in beats ÷ 1,000,000,000.
An example with a made-up round price of 1,000,000 beats: sending PLS costs 21,000 × 1,000,000 ÷ 1,000,000,000 = 21 PLS. A HEX stake at 95,000 gas costs 95 PLS. Today's price is on the gas page.
What do Slow, Normal and Fast mean?
- The gas price has two parts: base fee + tip.
- The network sets the base fee for each block. It is burned.
- The tip goes to the validator that makes the block.
- Slow, Normal and Fast are the cheapest 10%, the middle and the top 10% of prices paid in the last 20 blocks.
- A new block comes about every 10 seconds.
Wallet apps set the fee by themselves. Most people never need to change it.
When are PulseChain fees lower?
The gas page gives the data to judge it:
- The base fee over the last 24 hours, with its low and high.
- A grid of the base fee by hour for the last 7 days (UTC).
- Which contracts use the most gas in recent blocks.
- In Easy mode, one line: fees are lower than usual, normal, or higher than usual today.
Questions people ask
Why did a failed transaction still cost a fee?
The network did the work before the transaction failed. The fee pays for that work, so it is not returned.
Is a beat the same as gwei?
Yes. It is the same unit, one billionth of a PLS. PlsLens calls it a beat.
Why does a HEX stake cost more than sending PLS?
Starting a stake runs code in the HEX contract and stores the stake, so it uses about 70,000 to 95,000 gas. A plain transfer uses 21,000.
Where does the fee go?
The base fee is burned. The tip goes to the validator that made the block.
Do I need to change the gas setting in my wallet?
Usually not. Wallets pick a price by themselves. The gas page shows what Slow, Normal and Fast cost if a wallet asks.
