# NFTX

## Docs

- [Welcome](https://docs.nftx.io/readme.md): NFTX v4 — a neutral fungibility layer for NFTs, rebuilt on Uniswap V4. Turn a collection into a liquid, tradable market.
- [Introduction](https://docs.nftx.io/getting-started/introduction.md): What NFTX v4 is, in one page — a neutral fungibility layer that turns NFT collections into liquid, tradable markets on Uniswap V4.
- [Quickstart](https://docs.nftx.io/getting-started/quickstart.md): A short, hands-on path through the most common NFTX v4 actions.
- [Floor Tokens](https://docs.nftx.io/how-it-works/floor-tokens.md): How a collection becomes a fungible ERC-20 backed 1:1 by its pool — and why that makes NFTs instantly tradable.
- [Liquid Listings](https://docs.nftx.io/how-it-works/liquid-listings.md): Sell a non-floor item at a price you choose and get paid at floor value immediately — the self-assessed listing system at the heart of NFTX v4.
- [Swaps & Trade-Ups](https://docs.nftx.io/how-it-works/swaps-and-trade-ups.md): Instant ETH ⇄ token swaps, floor-to-floor NFT swaps, trading up into rarer items, and permissionless re-pricing.
- [Creator Royalties](https://docs.nftx.io/how-it-works/creator-royalties.md): How NFTX honours creator royalties: optional for most collections, enforced for ERC721-C collections whose creators opt in through the Royalty Gate.
- [Flex Pools](https://docs.nftx.io/how-it-works/flex-pools.md): Pair a collection's floor token with any token you like — USDC, another project's token, ETH — in extra Uniswap V4 pools beside the canonical flETH pool.
- [Collection Lifecycle](https://docs.nftx.io/how-it-works/collection-lifecycle.md): How a collection is launched onto NFTX and how a community-driven shutdown gives final holders a fair exit.
- [Migrating from NFTX v2/v3](https://docs.nftx.io/how-it-works/migrating-from-legacy.md): How to move NFTX v1–v3 vault tokens into v4 — whole NFTs migrate in one transaction, and sub-unit "dust" balances get a 1:1 swap path.
- [Vaults](https://docs.nftx.io/core-concepts/vaults.md): The container at the heart of every NFTX collection — one collection's NFTs, one fungible token, backed 1:1.
- [Minting & Redeeming](https://docs.nftx.io/core-concepts/minting-and-redeeming.md): The two feeless doors in and out of a collection's fungible state — deposit an NFT to mint a token, burn a token to redeem an NFT.
- [Fees](https://docs.nftx.io/core-concepts/fees.md): Feeless entry and exit, listing tax and swap fees where value is priced, and real yield routed back to liquidity providers.
- [Overview](https://docs.nftx.io/contracts/contracts.md): The NFTX v4 on-chain contracts — what each one does, how they fit together, and where they're deployed.
- [Deployment Addresses](https://docs.nftx.io/contracts/addresses.md): Deployed NFTX v4 contract addresses on Ethereum Mainnet, Base Mainnet, Arbitrum One, Ink, Arc, ApeChain, Robinhood Chain, Ethereum Sepolia, Robinhood Chain Testnet, and the earlier Base deployments.
- [Creator Token Approvals](https://docs.nftx.io/contracts/creator-token-approvals.md): How ERC721-C collections work with NFTX: allow NFTX's operators for feeless trading, or enforce creator royalties through the Royalty Gate.
- [Royalty Gate](https://docs.nftx.io/contracts/royalty-gate.md): The royalty-charging entrance to the Locker for ERC721-C collections that enforce creator royalties on NFTX.
- [Locker](https://docs.nftx.io/contracts/locker.md): The vault at the center of NFTX v4 — custodies NFTs, mints collection tokens, and exposes deposit, redeem, and swap.
- [Collection Token](https://docs.nftx.io/contracts/collection-token.md): The per-collection ERC-20 that represents a collection's floor.
- [Listings](https://docs.nftx.io/contracts/listings.md): The self-assessed listing system — liquid and Dutch listings priced in floor multiples, with tax prepaid on creation.
- [Tax Calculator](https://docs.nftx.io/contracts/tax-calculator.md): Prices the listing tax from floor multiple and duration, with a softening kink above 2.00x floor.
- [NFTX V4 Hook](https://docs.nftx.io/contracts/nftx-v4-hook.md): The Uniswap V4 hook — the single integration point for NFTX v4 pool fees and swaps.
- [NFTX Flex Hook](https://docs.nftx.io/contracts/nftx-flex-hook.md): The second Uniswap V4 hook — permissionless pools pairing a collection token with any whitelisted pair token, sharing the canonical hook's fee logic.
- [Zap](https://docs.nftx.io/contracts/zap.md): Atomic ETH ↔ NFT and ETH ↔ collection-token flows in a single call.
- [Migrator Zap](https://docs.nftx.io/contracts/migrator-zap.md): Atomic NFTX v2/v3 → v4 migration — redeem whole NFTs from a legacy vault and mint v4 floor tokens in one call — plus an owner-settled dust escrow for sub-unit legacy balances.
- [Collection Shutdown](https://docs.nftx.io/contracts/collection-shutdown.md): A community-driven wind-down path for illiquid collections, liquidating NFTs via a Sudoswap auction.
- [Supporting Contracts](https://docs.nftx.io/contracts/supporting.md): The Locker Manager, collection launch gates, the liquidation bonding curve, and token escrow.
- [Audits](https://docs.nftx.io/security/audits.md): Who has reviewed the NFTX v4 contracts — manual audits by Sherlock and Hooks.wtf, plus regular AI-assisted review rounds built on Trail of Bits and Uniswap security skills.
- [Overview](https://docs.nftx.io/art-blocks/art-blocks.md): Why Art Blocks projects need a wrapper before they can become an NFTX collection, and how wrapping works end to end.
- [Wrapper Factory](https://docs.nftx.io/art-blocks/wrapper-factory.md): ArtBlocksWrapperFactory — the curated core registry, permissionless wrapper deployment, and predicting a wrapper's address before it exists.
- [Project Wrapper](https://docs.nftx.io/art-blocks/project-wrapper.md): ArtBlocksProjectWrapper — wrapping and unwrapping Art Blocks tokens, the ID mapping, live metadata proxying, and the recovery path.

- [Swaps](https://docs.nftx.io/api-reference/swaps.md): Swap quotes, approval checks, and executable calldata. The API prices and builds the transaction; your wallet signs and submits it.
