# SentX > SentX is an NFT marketplace, launchpad and AI creation suite on the Hedera Hashgraph > network. Marketplace listings and offers use Hedera allowances that the owner grants and > can revoke; trades transfer assets directly between the participating wallets. The > marketplace shows live listings, sales, floor prices, offers and auctions for Hedera NFT > collections. Creators launch collections and mint NFTs, generate AI images, video, music > and 3D models through DreamForge, and traders earn the $SENTX reward token. ## Platform - [Marketplace](https://sentx.io/nft-marketplace/collections): buy-now listings, offers on any NFT, collection offers, bulk list/buy and time-bound auctions, across supported Hedera NFT collections. Also see [activity](https://sentx.io/nft-marketplace/activity) and [new listings](https://sentx.io/nft-marketplace/newlistings). - [Launchpad](https://sentx.io/launchpad): NFT mints, free claims and NFT swaps, with whitelists, token gating and per-wallet limits. - [Forever Mint](https://sentx.io/about/forever-mint): a mint that randomly selects the NFT you receive from a pool, using on-chain PRNG. A trademark of Dead Pixels Ghost Club; SentX supplies the launchpad tooling and interface. - [DreamForge](https://sentx.io/dreamforge): AI image, video, music and 3D model generation, NFT/token minting, IPFS pinning and metadata tools, paid from DreamForge credits topped up with HBAR. - [Music](https://sentx.io/music): albums released as Hedera tokens; each copy is a numbered serial, and owning one plays and downloads the album. [How a release works](https://sentx.io/music/about). - [$SENTX token and rewards](https://sentx.io/rewards/sentx-token): earned by trading and launchpad activity, spent on Magic Items and discounted NFTs. - [Hall of Fame](https://sentx.io/hall-of-fame): leaderboard of the most-favorited NFTs and collections, by time window. - [NFT tools](https://sentx.io/nft-tools/bulk-send): utilities including bulk NFT transfers, wallet-holder snapshots and Pick-a-Winner random draws from market activity. Bulk transfers above the free quota per job are charged. - [Creators](https://sentx.io/launchpad/launch-with-us): a self-serve Creator Panel (public beta) to launch a collection and mint event, or a hands-on launch with the SentX team. ## Key facts - SentX runs on Hedera mainnet. Hedera network fees apply separately from marketplace fees and any creator royalty. - Non-custodial trading: SentX does not hold listed NFTs or HBAR. Listings and offers use Hedera allowances that the owner grants and can revoke at any time. - Marketplace fee is 2% on a standard sale and 2.5% on an auction sale. A royalty is set by the collection's own token and enforced by the network, not by SentX. - Supported wallets: HashPack, Kabila, Dropp, Magic, and wallets that support WalletConnect v2 on Hedera. - $SENTX (token 0.0.2672057) is earned through platform activity such as trading and launchpad mints; it was not sold in an ICO. Supply is capped at 10M, and 50% of every redemption is permanently burned. - The launchpad supports three mint types: a priced Mint, a Free Claim, and an NFT Swap. - [Hedera case study on SentX](https://hedera.com/case-study/sentx). ## URL shapes - Collection: `https://sentx.io/nft-marketplace/` - NFT: `https://sentx.io/nft-marketplace//`.

Generation and minting are priced separately. ## Notes - NFT names, descriptions and metadata are user-generated content.
