How to Use CryptoFeeWatch

Three simple steps to check real-time gas fees and pick the right speed tier — so you never overpay for a blockchain transaction again.

3-Step Guide

1

Select a Blockchain

Choose the network you want to transact on — Bitcoin, Ethereum, Solana, Polygon, or any other supported chain. Each blockchain has its own fee market and denomination (sat/vB for BTC, Gwei for ETH, lamports for SOL).

2

Read the Current Fee Levels

You will see three tiers: Slow, Standard, and Fast. Each shows the current fee rate and an estimated confirmation time. Rates update in near real-time from mempool data and block explorers.

3

Choose Your Speed Tier

Not in a hurry? Pick Slow to pay the minimum. Need the transaction confirmed quickly — e.g., during a trade or NFT mint? Choose Fast. Copy the suggested fee into your wallet or let your wallet auto-detect via EIP-1559.

Frequently Asked Questions

What is a gas fee?+
A gas fee is the cost you pay to have your transaction processed on a blockchain. On Ethereum, "gas" measures the computational effort required. You pay gas in ETH (denominated in Gwei). On Bitcoin the fee is in satoshis per virtual byte (sat/vB).
Why do Ethereum fees vary so much?+
Ethereum has a limited block size. When demand for block space is high — during token launches, NFT mints, or market volatility — users bid higher fees to get their transactions included first. This auction mechanism causes fees to spike and fall rapidly.
What is Gwei?+
Gwei (gigawei) is a denomination of ETH: 1 ETH = 1,000,000,000 Gwei. Gas prices are quoted in Gwei because the numbers are more readable — "20 Gwei" is easier to work with than "0.00000002 ETH". Your total fee = gas used × gas price in Gwei.
When are crypto fees lowest?+
Generally, fees are lowest during weekends (UTC) and late-night/early-morning hours when Western markets are inactive. For Ethereum, Sunday 02:00–08:00 UTC is historically cheap. Bitcoin fees spike around halving events, ETF inflows, and ordinal inscription waves.
What is a mempool?+
The mempool (memory pool) is a waiting area for transactions that have been broadcast to the network but not yet confirmed in a block. Miners and validators pick transactions from the mempool, usually prioritising those with the highest fees. A congested mempool means higher fees.
How do I set custom gas in MetaMask?+
On the transaction confirmation screen, click "Edit" next to the estimated fee. Switch to "Advanced" mode and enter the Max Base Fee and Priority Fee (tip) in Gwei. Use the values from CryptoFeeWatch's Standard or Fast tier. Make sure your Max Fee is above the current base fee or the transaction may get stuck.
What's the difference between slow, standard, and fast?+
Slow: lowest fee, confirmation may take 30+ minutes (or longer if fees rise). Standard: mid-range fee, typically confirmed within 1–3 blocks (~15–45 s on Ethereum, ~10–30 min on Bitcoin). Fast: premium fee, aims for inclusion in the very next block.
Are Solana fees cheaper than Ethereum?+
Yes — by a large margin. A typical Solana transaction costs less than $0.001. Ethereum base fees during peak periods can reach $10–$80+ per transaction. However, Solana achieves this through a different architecture (high throughput, centralised validators) with different security trade-offs.
What causes Bitcoin fees to spike?+
Bitcoin fee spikes are driven by: (1) high on-chain activity such as exchange withdrawals or large batched payments, (2) Ordinals / BRC-20 inscription waves that fill blocks with data, (3) post-halving periods when block rewards drop and miners rely more on fees, and (4) general bull market transaction volume.
