Onchain Video

Open your wallet, pick a video, and publish it where links can’t break. Onchain Video turns a normal upload into a verifiable record on the Blast network. Start by connecting a compatible EVM wallet, confirming the network, and creating a profile handle. Prepare your file (H.264 MP4 or WebM works well), add a title, description, tags, and a cover image, then upload. Before you hit publish, choose visibility (public or unlisted) and review the onchain summary: content hash, storage pointer, and metadata. Confirm the transaction to finalize the publish; your wallet signs and covers a small network fee. You’ll receive a content ID and a shareable link that resolves to the player and the onchain entry.

Watching is equally direct. Paste a link, browse by address, or search tags to find videos. Each item displays its source address and an immutable checksum so you can verify authenticity. Use playlists to group episodes, save bookmarks to your wallet, and share deep links that open the exact timestamp. If a creator posts an update, a new record points back to the original, preserving history. Since the reference is onchain, mirrors or gateways can change over time without breaking your link.

For teams and power users, batch workflows speed things up. Pre-encode your catalog to web-friendly bitrates, auto-generate thumbnails and captions, and use the contract’s public methods to script uploads from a CI job. Store content IDs in your CMS, and drive site pages from onchain events so your catalog stays in sync. Schedule releases by preparing drafts and publishing when you’re ready. If you migrate from a Web2 host, publish the same file onchain and map legacy URLs to the new content IDs; your audience can verify the move by checking your address.

Operating tips: keep files small enough for smooth playback; long-form pieces stream best when segmented HLS or efficient MP4 is used. Test on a Blast test network before main publishing. Budget for network fees when releasing large batches. Maintain a backup of your storage pointers and content IDs. Safeguard your wallet keys—ownership is bound to your address, and recovery isn’t centralized. If you need to correct metadata, publish an updated entry and mark it as the canonical version. Developers can embed the player with a simple content ID and query contract events for lists, favorites, and channel updates, enabling apps that surface exactly the videos users care about.
