# DexTrending Documentation > Reference for buying and running Dexscreener trending campaigns on Solana and six EVM chains. A package buys a fixed block of unbroken hours on the trending list; position within the list is set by market activity and is not sold.

You buy 12 or 24 hours, paste a contract address, and press Launch yourself. - [How a campaign works](https://docs.dextrending.net/how-a-campaign-works.md): What runs behind your pair during a window, which signals the Dexscreener board reads, and why volume on its own does not move it. - [What you are buying](https://docs.dextrending.net/what-you-are-buying.md): A package is a block of unbroken hours on the trending list. This page states exactly what is committed, what is not, and why. - [Connecting a wallet](https://docs.dextrending.net/connecting-a-wallet.md): Your wallet is your account. Connecting takes one signature, costs nothing, and never grants spending permission. ## Packages and payment - [Packages and pricing](https://docs.dextrending.net/packages-and-pricing.md): Four packages across two chain groups. One flat figure each, paid once in USDC, with nothing added afterwards. - [Paying with USDC](https://docs.dextrending.net/paying-with-usdc.md): Every package is paid once in USDC, on whichever supported network suits you. Credit lands automatically when the transfer confirms. - [Payment troubleshooting](https://docs.dextrending.net/payment-troubleshooting.md): What to do when a payment does not credit: expired windows, wrong networks, missing transfers and stuck confirmations. ## Running a campaign - [Adding a project](https://docs.dextrending.net/adding-a-project.md): Save any token to your shelf by pasting its contract address. Free, unlimited, and it runs nothing until you launch. - [Launching a campaign](https://docs.dextrending.net/launching-a-campaign.md): Spend a package against a saved pair. The campaign starts the moment you press the button, with no approval step in between. - [Tracking progress](https://docs.dextrending.net/tracking-progress.md): Campaign states, the progress bar, and how to read what is happening while a window runs. - [When the window ends](https://docs.dextrending.net/when-the-window-ends.md): What the end of a paid window actually changes, what stays, and how to decide whether to run another one. ## Networks - [Supported networks](https://docs.dextrending.net/supported-networks.md): Solana and six EVM chains, with the exchanges covered on each and what differs between the two pricing groups. - [Entry times by network](https://docs.dextrending.net/entry-times.md): How long it takes for a pair to appear on the trending list after a window opens, per network, and how to plan around it. - [Solana campaigns](https://docs.dextrending.net/solana-campaigns.md): What is specific to running a window on Solana: the pools covered, pump.fun graduates, and why the busiest board costs more. - [EVM campaigns](https://docs.dextrending.net/evm-campaigns.md): Running a window on Ethereum, BNB Chain, Base, Arbitrum, Polygon or Avalanche, and how the six differ from one another. ## API for developers - [Introduction](https://docs.dextrending.net/api-introduction.md): A small REST API for buying-side automation: list your packages, launch campaigns against a pair, and track them from your own code. - [Authentication](https://docs.dextrending.net/api-authentication.md): Generate a key in the panel and send it on every request. Keys carry full account access, so treat them as secrets. - [Packages endpoint](https://docs.dextrending.net/api-packages.md): GET /packages returns every package on the account with its state. Available ones can be launched. - [Campaigns endpoint](https://docs.dextrending.net/api-campaigns.md): List campaigns with live status and progress, or launch a package against a pair. Launching is irreversible. - [Token endpoint](https://docs.dextrending.net/api-token.md): GET /token reads a pair the same way the panel does. Use it to validate an address before spending a package on it. - [Errors and rate limits](https://docs.dextrending.net/api-errors.md): Every status code the API returns, what causes it, and the rate limit you are working within. ## Affiliate - [How the programme works](https://docs.dextrending.net/affiliate-programme.md): Earn {{affiliate}}% on every package bought through your link. Your wallet is the account, so there is nothing to sign up for. ## Help - [Frequently asked questions](https://docs.dextrending.net/faq.md): The questions that come up most: what a package covers, what it does not, pricing, timing, payment and safety. - [Contact support](https://docs.dextrending.net/contact-support.md): How to reach support, what to include so it can be answered in one reply, and what nobody from DexTrending will ever ask you for. ## Elsewhere - [Main site](https://www.dextrending.net/): packages, pricing and how the ranking works - [Buy a package](https://www.dextrending.net/trending/buy): the panel where campaigns are bought and launched - [Guides](https://www.dextrending.net/blog): longer research articles on trending costs and timing
