Field survey · four chains · live
See what it costs to launch and trade a coin, right now.
We ask each network for its live fee and turn it into dollars, so you can pick the cheapest place before you spend anything.

How it works in 3 steps
- 01Pick a jobSend money, swap a coin, or launch your own.
- 02We ask four networksEach one tells us its live fee; we price it in dollars.
- 03The needle pointsYou see the cheapest chain and every cost behind it.
Reading fees is free. Nothing is signed, moved or charged on this site.
Tool 1 · Fee board
Today's cost of doing things, side by side
What this does: shows the live network cost of a transfer, a swap and a coin launch on four chains, in dollars.
| Chain | Gas token | Send | Swap | Launch a coin |
|---|---|---|---|---|
How each number is worked out
- Solana: 5,000 lamports per signature, plus a priority fee = price × compute units. The price is read live from recent slots (the lowest fee that still landed). Launches add refundable rent deposits.
- Ethereum: gas units × (next block's base fee + tip). Tips come from the last 10 blocks (25th, 50th, 75th percentile).
- Base: same as Ethereum, plus a data fee for posting the transaction to Ethereum, read from the network's own fee oracle (upper bound).
- Robinhood Chain: gas units × the live gas price. The network's own estimate already includes its posting cost to Ethereum; we scale that by transaction size.
- Gas units and compute units for each job are typical sizes, labelled estimate. A launchpad's own platform fee is not included.
How a fee is made
Four layers stack into one price
- The stamp. Every transaction pays a small fixed fee for its signature or its base gas.
- The work. Bigger jobs, like a swap, use more computing, measured in units and priced live.
- The posting. Base and Robinhood Chain also pay Ethereum to store a copy of the transaction.
- The deposit. On Solana, new accounts need a deposit that you can later get back.
Tool 2 · Exact Solana quote
Ask Solana itself what a transaction will cost
What this does: builds a real, unsigned transaction and asks the network to price it. It is never signed or sent.
The network's answer appears here, with our own formula next to it so you can see they agree.
Tool 3 · Real blocks
What people actually paid in the latest blocks
What this does: reads the most recent finished block (Solana) or the last 20 blocks (other chains) and charts real fees.
Pick a chain and press Sample now. Solana reads one whole block (about 1 MB), so we only do it when you ask.
Tool 4 · Budget
Plan a launch day: how much will the fees add up to?
What this does: adds up the live cost of a list of jobs on one chain, and checks it against a wallet's real SOL balance.
Your total appears here, split into network fees and refundable deposits.
Tool 5 · Deposits
The Solana deposits you can get back
What this does: prices the storage deposit for any account size, and counts how much SOL a wallet has parked in coin accounts.
The deposit and the wallet's parked SOL appear here.

Measured job sizes
Replace the typical gas sizes with sizes measured from real recent swaps and launches on each chain.

Add a chain only when a free public node answers from a browser.
Tokenomics planned
The Feecompass coin
The coin is not launched yet. This is the planned structure. The tools above work without it.
- 0% sold on the public launch curve, to anyone, at the same rules
- 0% placed in liquidity when the curve completes, then locked or burned
- 0% team allocation; the team only holds what it buys on the curve
- 0% presale; mint and freeze powers switched off
- Supply

No returns are promised. A coin can lose all its value. The fee tools stay free with or without it.
Glossary
Fee words, in plain English
- Gas
- The unit chains like Ethereum and Base use to measure work. You pay gas × gas price.
- Gwei
- A billionth of an ETH. Gas prices are quoted in it.
- Lamport
- The smallest piece of SOL: one billionth of a SOL.
- Compute units
- Solana's measure of work. A simple send uses a few hundred; a swap uses many thousands.
- Priority fee
- An optional tip on Solana, priced per compute unit, to get in first when it is busy.
- Rent deposit
- SOL locked to keep an account's data stored. You get it back when the account is closed.
- Mint
- The address that defines a coin on Solana: its supply and decimals.
- Layer 2
- A chain, like Base or Robinhood Chain, that posts its data to Ethereum and pays a small fee for it.
FAQ
Field notes
What is this, in one sentence?
A live price list for blockchain fees: it shows what sending, swapping or launching a coin costs on four chains this minute, in dollars.
Is it safe? Does it touch my money?
It only reads. Connecting a wallet shares your public address so the budget and deposit tools can read your balance. The exact-quote tool builds a transaction to get a price, but never asks you to sign it, so nothing can move.
Are these numbers exact?
The fee prices are live from each network. The size of each job (how much gas a swap uses, for example) is a typical figure and is marked "estimate". Real swaps vary with the route and the app you use.
Why is Solana's priority fee often zero?
Solana reports the lowest tip that still got into each recent slot. Often that is zero. Busy moments show up in the "In a hurry" level, which uses the top of the recent range.
Does a launch cost include the launchpad's fee?
No. We show what the network charges. Launchpads may add their own fee on top, and on Solana part of the launch cost is a refundable deposit.
Where do the prices come from?
Public network nodes for fees, and a public price feed for SOL and ETH. No keys, no accounts, and nothing about you is stored on a server.
