Blockchain OG Image

When to use

• You're launching a blockchain project, protocol, wallet, or dApp and every shared link shows a blank preview
• Your current OG image is a busy network diagram with a logo nobody can read at thumbnail size
• You need preview art for a token launch, docs site, testnet announcement, or hackathon page
• Your project's links get shared in chat apps and timelines where the preview is the first impression
• You're rebranding a chain or tool and the old preview still shows the old name

Workflow

1. Lock the message (input: project name + one-line promise → output: headline + subhead)
   An OG image gets about one second at thumbnail size. Pick a headline of 2–6 words — the project name plus what it does ("Aurora Chain — fast, cheap settlement") — and one subhead under 10 words. Crypto previews fail most often by saying too much: skip the tokenomics, the roadmap, and the partner logos. One promise. If the promise needs a paragraph, the message isn't ready; the image can't fix it.
2. Choose the visual metaphor (input: headline → output: one visual idea)
   Pick ONE visual idea and commit: a block-chain motif (connected blocks receding into depth), a network constellation (nodes and edges on a dark field), a single oversized token/coin mark, or an abstract wave of the brand's colors. One idea, large and simple — the preview is 240px wide in most timelines, and a second idea becomes noise. Avoid cliché overload: no rockets, no moons, no laser eyes, no "to the moon" energy. The goal is credible infrastructure, not meme coin.
3. Compose for the crop (input: visual idea → output: layout)
   Build at 1200×630 with all critical text inside the center 90% — platforms crop the edges. Two layouts work best: left-aligned text with the visual motif on the right, or centered text over a dark field with the motif behind at low opacity. The project name or wordmark goes large (90–110px, bold); the subhead sits below at 40px+. If you use a token symbol or logo, place it once, large, not tiled. Leave real breathing room around the text — a cramped preview reads as untrustworthy.
4. Style for legibility (input: layout → output: styled image)
   High contrast is non-negotiable: light text on a deep dark background, or dark text on a light one — never mid-tone on mid-tone. Use at most two typefaces and two accent colors plus neutrals. The motif stays subtle behind the text (dimmed, blurred, or low-opacity) so the words win. Test the export at 240px wide: if the project name isn't readable, the image failed regardless of how good it looks at full size.
5. Export and verify everywhere (input: styled image → output: verified og:image)
   Export as JPEG or PNG at exactly 1200×630, under 1MB. Set og:image, og:image:width, og:image:height, and twitter:card (summary_large_image) with an absolute URL. Check it in at least two validators — X's card validator and a chat-app paste — plus a link preview in a messaging app. Use a versioned filename (og-v2.jpg) when updating, so stale caches don't keep serving the old image for days.
