> Creator-owned onchain memberships and public tools for building custom membership artwork.

## Onchain renderer skill

- [Create onchain membership art](https://backedbyfans.xyz/skill): Give an agent an art brief and learn the creator workflow.
- [Complete renderer skill](https://backedbyfans.xyz/skill/SKILL.md): Agent instructions for dependencies, implementation, local testing, preview, and deployment.
- [Renderer interface](https://backedbyfans.xyz/skill/references/interface.md): Contract inputs, outputs, media behavior, and fixed compatibility surface.
- [Local renderer testing](https://backedbyfans.xyz/skill/references/local-testing.md): Foundry tests and representative local gallery workflow.
- [Browser deployment](https://backedbyfans.xyz/skill/references/deployment.md): Browser preview and creator-wallet deployment.
- [Download the toolkit](https://backedbyfans.xyz/skill/onchain-render-skill.tar.gz): Self-contained skill, scripts, Foundry template, references, and tests.
- [Preview a renderer](https://backedbyfans.xyz/render): Public browser tool for representative previews and deployment preparation.

## Product boundaries

- Robinhood testnet, chain ID 46630, is the supported public chain for custom renderers.
- Browser deployments are recorded in the creator's onchain renderer list for later rediscovery. The list is not an approval gate; compatible renderers can still be shared and used directly by contract address.
- There is no cross-chain lookup. Mechanical checks establish interface behavior for tested inputs, and the creator decides whether to use the design.
- Renderer deployment uses the creator's browser wallet. Agents never need a private key export.
