Base Ecosystem skill
Tools for building on Coinbase's Base L2: human-readable names and Mini Apps.
Basenames (name.base.eth)
ENS-style naming on Base. Resolution verified live against Base mainnet.
| Tool | Purpose |
|---|
chaingpt_base_resolve_name | Forward (name → address) or reverse (address → primary name). Auto-detects from input. Read-only. |
chaingpt_base_name_availability | Is a label available + the price for N years. Read-only. |
chaingpt_base_register_name_tx | Build the UNSIGNED registration tx (payable; sets the addr record + optional reverse record). Mainnet needs acknowledgeMainnet:true. |
chaingpt_base_resolve_name query=jesse.base.eth → address. query=0x… → name.
Base App / Farcaster Mini Apps
A Mini App is a web app that runs inside the Base App and Farcaster from a
feed post (Farcaster Mini Apps spec; MiniKit wraps OnchainKit on the Base side).
These tools are pure generation/validation — no network, no keys.
| Tool | Purpose |
|---|
chaingpt_miniapp_manifest | Generate /.well-known/farcaster.json (the miniapp object + frame alias). |
chaingpt_miniapp_embed | Generate the fc:miniapp (+ legacy fc:frame) HTML meta tag for shareable embeds. |
chaingpt_miniapp_validate | Validate a manifest against the spec (required fields, lengths, https, category). |
The manifest's accountAssociation (domain-ownership proof) must be signed
with your Farcaster custody key — generate it with npx create-onchain --manifest.
The tool emits a placeholder and explains the step.
Reliability
EVM reads use a public-RPC fallback chain. For heavy use set BASE_RPC_URL to a
dedicated endpoint. 0 ChainGPT credits.
