Quickstart

Get a wallet onto X Layer, buy your first coin, or put one of your own on the board. Five minutes, no code.

Everything on size.fun happens on X Layer, chain 196. If your wallet has never been there, adding it takes one prompt — the site offers it the first time you connect.

Get a wallet onto X Layer#

Any EVM wallet works. OKX Wallet and MetaMask are the two most people use here.

  1. Open size.fun and hit Connect.
  2. Pick your wallet from the list. Wallets announce themselves, so what you see is what is actually installed rather than a guess.
  3. Approve the network prompt. If you decline it you stay connected, you just cannot trade until you switch.
Network nameX Layer
Chain ID196
CurrencyOKB
RPChttps://xlayerrpc.okx.com
Explorerhttps://www.oklink.com/xlayer

Opens your wallet's own prompt. Nothing is sent anywhere.

The button adds the network to a wallet already installed in this browser. If nothing happens, your wallet is on your phone or is not exposing itself to this page — add the network by hand from the values above, or just connect at size.fun, which offers the same prompt.

Fund it with OKB#

OKB is the gas token and the asset every coin trades against. Two ways to get some onto X Layer:

  • Withdraw from OKX and pick X Layer as the network. Usually the cheapest route.
  • Bridge from Ethereum through the official X Layer bridge.

Blocks are one second and fees are a fraction of a cent, so you do not need to hold much for gas. What you bring is what you trade with.

Buy a coin#

  1. Open a coin from the board. The page shows its price, its market cap and how far along its curve it is.
  2. Enter an amount of OKB and hit Buy. You are trading against the curve, not against another person — there is no order book and no counterparty to wait for.
  3. Confirm in your wallet. It lands in the next block.

Selling is the same in reverse: enter an amount of the coin, approve it once, then sell. The curve always quotes a price, so a sell never fails for lack of a buyer.

The first 15 seconds

A buy landing in the opening seconds of a launch pays an extra tax that starts at 99% and decays to nothing within 15 seconds. It exists to make sniping a launch pointless. If you are not a bot, you will never notice it — just do not rush a brand-new coin.

Launch a coin#

  1. Hit Launch in the sidebar.
  2. Give it a name, a ticker, an image and a description. Socials are optional and go on the coin's page.
  3. Set a creator tax if you want one — 0 to 10% of every trade, paid to you on top of your share of the base fee. Most launches leave it at 0.
  4. Pay the 0.01 OKB launch fee. Trading opens in the same transaction.

You get no free tokens. If you want a position in your own coin, buy it from the curve — and buy it in the same transaction as the launch, which the site does for you when you enter a dev buy. That closes the window a sniper would otherwise use. See Launch a token for the same thing in code.

Collect what you earn#

Fees from your coin accumulate on its curve as you trade. Getting them into your wallet is two steps, both on the creator dashboard:

  1. Sweep the curve. This splits the pending fees and moves your share into the escrow.
  2. Claim from the escrow. One claim collects everything you are owed across every coin you have launched, before and after graduation.

The escrow pays whoever calls it, so there is no address to type and nothing to send to the wrong place. Claiming covers it in detail.
