+
+New package to run your own faucet service. We'll use this soon for our testnet in place of `@latticexyz/services`.
+
+To run the faucet server:
+
+- Add the package with `pnpm add @latticexyz/faucet`
+- Add a `.env` file that has a `RPC_HTTP_URL` and `FAUCET_PRIVATE_KEY` (or pass the environment variables into the next command)
+- Run `pnpm faucet-server` to start the server
+
+You can also adjust the server's `HOST` (defaults to `0.0.0.0`) and `PORT` (defaults to `3002`). The tRPC routes are accessible under `/trpc`.
+
+To connect a tRPC client, add the package with `pnpm add @latticexyz/faucet` and then use `createClient`:
+
+```ts
+import { createClient } from "@latticexyz/faucet";
+
+const faucet = createClient({ url: "http://localhost:3002/trpc" });
+
+await faucet.mutate.drip({ address: burnerAccount.address });
+```
