Zora is an onchain social app for tradable ERC-20 posts

Zora is an onchain social app, meaning its posts and markets use a public blockchain, where each post becomes a tradable digital coin. Publishing deploys an ERC-20 coin on Base, opens a Uniswap v4 market and gives the creator a fixed allocation. Other users buy or sell that coin with Base assets such as ETH, USDC or ZORA. The model joins media, audience participation and market activity in one public transaction history.

Deciding whether Zora fits the post

Next to that, Zora post coins are media-linked ERC-20 tokens for work that benefits from public ownership records, immediate trading and a creator-linked market.

The format works best when the market is part of the piece: an edition, meme, short video or visual whose audience may want a transferable position. A coin also gives the creator an onchain record of issuance and a fee stream linked to market activity. The fit weakens when the goal is private sharing, fixed-price access or a conventional newsletter. Public balances, variable prices and irreversible contract deployment change the publishing relationship, so the creator should decide what the coin represents before choosing a ticker or pairing asset.

Use this five-point decision checklist before publishing.

• Rights: You control the media and any linked material.
• Market intent: You want audience trading to form part of the release.
• Chain: You accept a persistent ERC-20 contract on Base.
• Identity: The coin name and ticker are final before confirmation.
• Liquidity: You accept variable execution as the pool receives orders.

Choose this structure when public trading forms part of the intended audience experience.

Fees and the cost of a trade

Zora trading costs combine a protocol pool fee, an interface transaction fee and Base execution costs.

The 1% pool fee

Creator Coins and Content Coins charge a 1% pool fee on their initial Uniswap market. The split assigns 0.5% to the creator, 0.2% to permanent market liquidity, 0.2% to the platform referrer, 0.04% to the trade referrer, 0.05% to the protocol and 0.01% to Doppler. Those components total exactly 1%. The platform referrer is fixed when the coin launches, while a trade referrer is set for each swap. Another trading route preserves this schedule only when it uses the same protocol pool and hook.

Interface and Base costs

Trades placed through Zora follow a separate interface fee schedule. An order below $50 pays $0.50, while an order of $50 or more pays 1%. The preview then incorporates Base execution, any relayer charge and price impact. A small order therefore faces a larger effective percentage from the fixed $0.50 component.

The all-in cost changes with order size, pool depth and Base data fees.

Publishing a first post on Base

A first Zora post is a media upload that deploys its coin and opens its Base market.

Prepare the media

The upload flow accepts up to 20 files in JPG, PNG, GIF or MP4 format, with a stated 6 GB maximum. Those four formats cover static images, animation and video. Confirm that captions, external links and depicted material are ready for public distribution because the coin contract gives the post a durable market identity.

Set the coin identity

Enter the coin name, ticker and optional description, then select the asset that will pair with the post. The ticker cannot be edited after publication. The web editor still permits later changes to the title, caption and artwork file, so ongoing maintenance affects presentation without replacing the original coin. An initial buy is optional and adds a trade to the publishing transaction.

Confirm the Base transaction

Base mainnet uses chain ID 8453 and ETH as its native currency. Coinbase Wallet, MetaMask and Rainbow support Base when the correct network is selected. Zora also accepts ETH, USDC and ZORA as trade payment assets. Before confirmation, review the blockchain fee, pairing choice and any initial purchase. After settlement, verify the transaction receipt, coin balance and contract address. A linked external wallet changes who pays network costs, while the deployed coin and market remain on Base.

What do buyers actually own on Zora?

A Zora buyer owns fungible ERC-20 units issued by a post's coin contract, not exclusive ownership of the media. Each unit is interchangeable with another unit from the same contract and appears in the holder's public Base balance. Buying does not transfer copyright, editorial control or a claim on the creator's business. It also does not make the post scarce like a one-of-one NFT. The coin records a market position tied to content, while any additional license or access right must be stated separately.

Creator Coins and Content Coins in one profile

Seen from the other side, Zora profiles combine a profile-level Creator Coin with Content Coins attached to individual posts.

Profile-level Creator Coins

One Creator Coin represents one account, and the username becomes its ticker. Its fixed 1 billion supply splits evenly: 500 million enter the open market and 500 million vest to the creator over 5 years. The 50% creator allocation unlocks linearly rather than arriving at once. Activation has no setup fee, but it is permanent, and each profile receives only one Creator Coin.

Post-level Content Coins

Every Content Coin has a fixed supply of 1 billion units: 10 million go to the creator immediately and 990 million enter the market. That division equals a 1% creator allocation and a 99% market allocation. The post coin and Creator Coin remain separate contracts, so their prices and holder lists can diverge even though the profile connects them.

The ZORA token is another Base ERC-20 with a fixed supply of 10 billion. It acts as a backing, payment and reward asset rather than representing one post. The relevant asset changes with the action: buying a profile selects its Creator Coin, while buying a post selects its Content Coin.

The Uniswap v4 machinery behind each coin

That said, Zora Coins Protocol is a factory-and-hook system that deploys ERC-20 contracts beside dedicated Uniswap v4 pools. The factory fixes supply and connects each coin to its market.

At deployment, the factory records the creator, name, symbol, metadata URI and payout recipient, then returns both a coin address and transaction receipt. Metadata can reference IPFS and follows the EIP-7572 pattern used by Zora tooling. Each swap reaches a custom Uniswap v4 hook. Its launch fee begins at 99% and decays over 10 seconds toward the coin's normal rate. For Creator Coins and Content Coins, 20% of trading fees becomes permanent pool depth. Doppler handles the initial liquidity position, while multi-hop conversion routes rewards to designated recipients.

ERC-20 compatibility lets Base applications read balances, request approvals and transfer units through standard contract calls. A different interface can therefore expose the same coin and Uniswap pool. Presentation metadata can change, but the contract address and recorded swaps remain part of Base history. That composability matters when the Zora app is one of several interfaces to the same contract.

Trade-offs and alternatives for onchain publishing

One level down, Zora's principal trade-off is that social publishing creates a live market whose price can move independently of creative quality.

Pool reserves and order flow set the market price. Limited depth increases price impact, while public Base records expose balances and transaction history to anyone reading the chain. Tickers persist after deployment, and activating a Creator Coin permanently adds it to the profile. Media edits change how a post appears without erasing earlier swaps. These properties reward deliberate preparation because the publication, asset and market begin together.

Farcaster emphasizes open social identity, conversation and portable connections without making every post an ERC-20 market. Lens also provides an onchain social graph for applications that need reusable profiles and social actions. Paragraph centers long-form publishing and email distribution, which suits writing where readership matters more than continuous coin trading (compare Using Zora ).

Manifold gives creators control over ERC-721 and ERC-1155 contracts for collectible editions. Foundation centers digital-art listings and auctions. Those formats fit work sold as distinct tokens or limited editions, while Zora Content Coins divide one post into a large fungible supply with an always-available pool.

On a practical level, Zora fits when a continuous market is part of the creative object and its audience experience.
