+# Tangle dApp monorepo (Nx + Yarn)
+
+## Quick commands
+- Install: `yarn install` (Node `>=18.18.x`, Yarn `4.x`)
+- Run dApp: `yarn nx serve tangle-dapp` (default `http://localhost:4200`)
+- Lint/test/build: `yarn lint`, `yarn test`, `yarn build`
+
+## Env
+- Start from `.env.example` (Vite vars are `VITE_*`)
+- Set `VITE_GRAPHQL_ENDPOINT` to your Envio/Hasura GraphQL (local indexer or mainnet)
+- Optional: `VITE_WALLETCONNECT_PROJECT_ID` for WalletConnect
+
+## Local protocol repo
+- `../tnt-core/` (sibling repo): protocol + claims migration contracts, gas relayer, indexer, etc.
+- When running locally, ensure:
+  - the chain you connect the UI to matches your `tnt-core` deployments
+  - `VITE_GRAPHQL_ENDPOINT` points at the indexer for that chain
+
+## Key code locations
+- App: `apps/tangle-dapp/` (Vite + React Router)
+- Restaking (EVM v2):
+  - GraphQL hooks: `libs/tangle-shared-ui/src/data/graphql/`
+  - Tx hooks: `libs/tangle-shared-ui/src/data/tx/`
+  - Write executor: `libs/tangle-shared-ui/src/hooks/useContractWrite.ts`
+- Seed scripts (Substrate dev):
+  - `yarn script:setupServices` (create blueprints)
+  - `yarn script:setupRestaking` (LST/vault/operator fixtures)
