Welcome to Edith¶
Edith is the backend for onboarding new users to HyperEVM — gasless relaying, HyperCore actions, and one-signature smart accounts, so a first-time user is on-chain without ever touching gas. Once they're on, the same three APIs handle Core-spot swaps and Core-native yield — and they work on any EVM chain and Solana too. Get an API key and build.
New to Hyperliquid on Edith? Start with the Hyperliquid on Edith hub. Otherwise, here are the three APIs:
| 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, forward HyperCore actions, and issue gasless smart accounts. | photon/quickstart.md |
| Vector | Swap routing and gasless swaps. Ranked route quotes, executable calldata, and Permit2-based gasless execution relayed through Photon. On Hyperliquid: quote and execute Core-spot swaps. | vector/quickstart.md |
| 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. On Hyperliquid: Core-native yield, including the flagship CoreWriter venue. | meadow/quickstart.md |
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.
- Working with an AI agent? Point it at Resources for AI agents.
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.
