## What is Opensee?

Opensee shows what a blockchain transfer actually costs right now – before you send it.

Check current network fees for Ethereum, Bitcoin, Solana, Base and Arbitrum in one place, see how those fees have moved over the past hours and weeks, and get a plain estimate of what a transfer, a swap or a contract call would cost in your own currency.

WHAT YOU GET
• Live network fees, each chain in its own unit – Gwei for Ethereum, Base and Arbitrum, sat/vB for Bitcoin, SOL for Solana. Every reading shows where it came from and when it was taken.
• Load at a glance. Each network is marked Low, Normal or High, so you can tell a calm moment from a busy one without reading the numbers.
• Fee history as candlestick charts over 24 hours, 7 days and 30 days. Ethereum and Bitcoin load their recent history the first time you open the app, so the charts are useful straight away.
• Cost estimates for the things you actually do – a basic transfer, a swap, a contract interaction – converted to US dollars, euros or pounds.
• Network comparison, with all five networks side by side and what a basic transfer costs on each.
• Check reminders. Pick a network and a time, and Opensee reminds you to look at its fees again.

SET IT UP THE WAY YOU WORK
Choose how often Opensee refreshes, or turn auto-refresh off and load fees only when you ask. Pick the currency values appear in, and the network and chart range that greet you when the app opens. Clear the stored fee history whenever you like.

PLEASE NOTE
Opensee is an informational tool. Fee estimates approximate network conditions that change quickly – always confirm the final fee in your wallet or service before approving anything. Opensee does not provide investment advice, does not recommend assets, and never takes custody of funds.
