Welcome to Edith¶
Edith is the backend for onboarding new users to HyperEVM — gasless relaying, one-signature smart accounts, and swaps, so a first-time user is on-chain without ever touching gas. The same three APIs work on any EVM chain and Solana, and reach Hyperliquid's Core layer (trading, Core-native yield) when you need it. Get an API key and build.
New to Hyperliquid on Edith? Start with the Hyperliquid on Edith hub. Otherwise, here are the three APIs:
| API | What it does | Start here |
|---|---|---|
| Photon | Gas-sponsored transaction relaying. Submit a transaction; Photon signs, pays the gas, manages nonces and retries, and reports status over polling, WebSocket, or webhooks. On Hyperliquid: relay to HyperEVM and issue gasless smart accounts (HyperCore actions available too). | Photon quickstart |
| Vector | Swap routing and gasless swaps. Ranked route quotes, executable calldata, and Permit2-based gasless execution relayed through Photon. Also quotes HyperCore Core-spot swaps. | Vector quickstart |
| Meadow | Auction-driven yield. Solvers bid APY for your deposit; one signature moves funds into the winning venue, non-custodially, with shares in your own address. Also routes into Hyperliquid Core venues (HLP vault, staking). | Meadow quickstart |
Where to start¶
- Building on Hyperliquid? Start with Hyperliquid on Edith — the map of every HyperEVM and HyperCore capability across the three services.
- New to Edith? Start with the Photon quickstart — your first sponsored transaction takes a few minutes.
- Building a swap flow? The Vector quickstart goes from quote to executed swap.
- Routing deposits to yield? The Meadow quickstart walks the auction → sign → deposit loop.

How these docs are organized¶
Each product section follows the same shape:
| Section | What it's for |
|---|---|
| Quickstart | A hands-on first run, end to end. |
| Core concepts / Why | How the product works and when to use it. |
| How-to guides & use cases | Task-oriented recipes for specific goals. |
| API reference | Every endpoint, parameter, and error, precisely. |
All three APIs require an API key — see Get API access.
