Live crypto prices, mempools and network fees

Reading the exchanges

What is a coin
worth right now?

Thirty-two assets, priced in this browser: over a live exchange socket when one will open, and by polling CoinGecko, through a small relay on this site that reads it once for every reader (or CoinPaprika, then Binance.US, when CoinGecko refuses), when none will. Which source is answering is named at the top of the list, because the honest version of "live" is knowing who is speaking.

By market cap

The top
thousand.

Every coin CoinGecko ranks in its first thousand, a page of 250 at a time, with the price, the day's move and the market cap as CoinGecko has them now — or, when CoinGecko refuses, CoinPaprika's own first thousand, and the note under these buttons says which. One of the thousand is named for super intelligence, the Artificial Superintelligence Alliance (FET), and it is ranked and priced like the rest. Press a row for that coin's card — chart, supply, all-time high — at the top of the page.

The list is read from CoinGecko when you reach it.

The meme desk

Twenty meme
coins.

Dogecoin, Shiba Inu, Pepe, dogwifhat, Bonk, FLOKI and fourteen more, priced by CoinGecko (by CoinPaprika when CoinGecko refuses, and named) and re-read every two minutes while you are here. Press one for its card. The tiles, with a chart on each, are on the meme desk.

On-chain

What the chains
are doing.

A price is what an exchange says. This is what the network itself says: how many transactions are waiting, what they are paying to get in, how fast the chain is going. Six chains can be read from a browser without a key — those six are here, and the rest of the deck is honest about not being readable rather than filled in with something plausible.

is reading.

The crypto desks and the business wire, merged and sorted by the clock. Nothing is rewritten or summarised here — the headline is the publisher's and the link goes straight to them.

Overview

Live crypto prices, read from the exchange and the chain.

MEM prices thirty-two crypto assets in your browser. It first tries to open a live exchange socket on Binance, Binance.US or Coinbase, starting with the one that last answered this browser (on a first visit from a US time zone, Binance.US), and whichever one answers is named on the page. If none will, the prices come from CoinGecko instead, polled every thirty seconds (less often while CoinGecko asks the page to slow down), and the page says so. Either way, CoinGecko supplies what a ticker stream does not carry: market cap, market-wide volume and rank, asked first through a small relay on this site that reads CoinGecko once for every reader and says when its copy is not fresh (CoinPaprika when CoinGecko refuses).

Beside the price is what the network itself says. Six chains can be read from a browser for free, without an API key, and those six are re-read every sixty seconds: Bitcoin's mempool and recommended fees from mempool.space; Ethereum's pending count from Blockchair and its base and priority fees over public JSON-RPC; Dogecoin and Litecoin from Blockchair; Solana's transactions per second and slot height from a public RPC; and Tron's latest block from TronGrid. The other twenty-six assets have no such endpoint, and MEM does not invent a reading for them.

Around them sit Alternative.me's Fear & Greed index; total market cap from CoinGecko, CoinPaprika or CoinLore, whichever answers first; an altcoin-season score, the share of the top fifty (Bitcoin and stablecoins excluded) that has beaten Bitcoin over thirty days; and headlines from Cointelegraph, Decrypt, CryptoSlate and CoinDesk, merged with the site's own business and tech wire and linked straight to the publisher. On the console, each asset also has a price chart over nine time windows, drawn from Binance candles, or from CoinGecko closing prices where Binance has none. MEM reads public market data only: it does not trade, hold funds or give financial advice. Share prices are in Stocks; the other market desks are in Markets.

Any coin can be looked up by name, ticker or nickname in the field at the top of the page: Bitcoin (btc, xbt), Ethereum (eth, ether), XRP (ripple), Dogecoin (doge), Solana (sol), Cardano (ada), BNB, TRON (trx), Litecoin (ltc), Shiba Inu (shib), Pepe, Toncoin (ton), Avalanche (avax), Chainlink (link), Polkadot (dot), Polygon (matic, pol) and the rest of CoinGecko's top thousand, with anything beyond that asked of CoinGecko's own search. A coin's card shows its price, 24-hour move, market cap, volume, rank, supply and all-time high from CoinGecko, with a chart; for the thirty-two assets priced here, the price comes from the live feed. Each card has its own address, such as labs.llc/mem/?coin=bitcoin.

The other edition

The live console.

The same readings as tiles on a dark ground: a chart on every tile that pans and zooms with open, high, low and close in its tooltip, the mempool deck behind each asset, and the sortable top thousand as one table. Same address, the other skin — your favourites and any coin you looked up come with you.
