- `ponder/`: New indexer replacing The Graph. `ponder.config.ts` selects network/contracts, `src/` holds TypeScript event handlers, `ponder.schema.ts` defines tables, `README.md` documents usage. Generated artifacts in `generated/` are auto-created by Ponder.
- `subgraph/base_sepolia/`: Legacy AssemblyScript implementation kept for reference during migration. Do not modify unless syncing schema changes between stacks.
- `landing/`: Vue 3 app (Vite + TypeScript) for the public launch site and forthcoming staking UI. See `src/views/` for pages, `env.d.ts` for injected globals.
- `services/txnBot/`: Node service that consumes the GraphQL API (`.graphclient`) to trigger `recenter()` and `payTax()` on-chain when profitable.
- `services/txnBot/`: Node service that consumes the Ponder GraphQL API to trigger `recenter()` and `payTax()` on-chain when profitable.
- `kraiken-lib/`: Shared TypeScript helpers (e.g., `bytesToUint256`) consumed by the landing app + bots.
## Environment Profiles
- `BASE_SEPOLIA_LOCAL_FORK`: Anvil fork bootstrapped by `scripts/local_env.sh`
- `BASE_SEPOLIA`: Public Base Sepolia testnet
- `BASE`: Base mainnet
## Execution Workflow
1. **Contracts**
- Build/test via `forge build` and `forge test` inside `onchain/`.
@ -16,23 +21,25 @@
2. **Indexer (Ponder)**
- Install deps (`npm install`).
- Configure environment via `PONDER_NETWORK` (`local`, `baseSepolia`, or `base`). Update `ponder.config.ts` addresses if deployments change.
- Configure environment via `PONDER_NETWORK` (`BASE_SEPOLIA_LOCAL_FORK`, `BASE_SEPOLIA`, or `BASE`). Update `ponder.config.ts` addresses if deployments change.
- Run dev mode with `npm run dev`; GraphQL served at `http://localhost:42069/graphql`.
- Handlers in `src/kraiken.ts` and `src/stake.ts` maintain rolling supply stats, ring-buffered hourly metrics, and position state.
3. **Frontend**
- `npm install` then `npm run dev` in `landing/`. Currently static marketing copy with placeholders for wallet/staking flows.
- Configure GraphQL endpoints via `VITE_PONDER_BASE_SEPOLIA`, `VITE_PONDER_BASE`, and optionally override `VITE_PONDER_BASE_SEPOLIA_LOCAL_FORK` (defaults to `http://127.0.0.1:42069/graphql`).
4. **Automation Bot**
- Requires `.env` with RPC + key. Queries indexer (Graph or Ponder) to decide when to pay tax or recenter liquidity.
- Requires `.env` with RPC + key. Queries the Ponder GraphQL endpoint to decide when to pay tax or recenter liquidity.
- `scripts/local_env.sh start` provisions and launches the bot automatically when running against the local fork.
## Migration Notes (Subgraph → Ponder)
- Schema parity: ensure any entity changes land in both `ponder.schema.ts` and legacy Graph `schema.graphql` until cutover.
- Event coverage: `Stake` events (`PositionCreated/Removed/Shrunk/TaxPaid/RateHiked`) mirrored from AssemblyScript handlers. Kraiken `Transfer` powers mint/burn/tax/UBI tracking.
- Ring buffer logic in `kraiken.ts` depends on block timestamps being monotonic; gaps >168 hours zero out the buffer. Verify `startBlock` in `ponder.config.ts` to avoid reprocessing genesis noise.
- Local deployment requires updating `ponder.config.ts` local contract addresses after each run or injecting via env overrides.
- Local deployment requires updating `ponder.config.ts` local contract addresses after each run or injecting via env overrides. The `BASE_SEPOLIA_LOCAL_FORK` profile assumes addresses generated by `DeployLocal.sol`.
- Ponder v0.13 exposes helpers via `context.client` / `context.contracts`; use these to seed stats from on-chain `totalSupply` and refresh `outstandingStake` straight from the `Stake` contract. All hourly projections now run off a JSON ring buffer on the `stats` row.
- Subgraph naming differs from the new schema (`stats_collection`, decimal shares). Until the web-app switches to Ponder’s GraphQL endpoint, keep the legacy entity shape in mind. Plan to provide either a compatibility layer or update `web-app/src/composables/useStatCollection.ts` to hit the new schema.
- Subgraph naming differs from the new schema (`stats_collection`, decimal shares). The web-app and txn bot now target the Ponder schema directly; keep legacy Graph compatibility only until the AssemblyScript stack is fully retired.
- Tax accounting must listen to `PositionTaxPaid` instead of guessing via hard-coded addresses. The old subgraph missed this; Ponder now increments the ring buffer segment on each tax payment.
- Liquidity bootstrap still depends on the Uniswap pool stepping through `recenter()`. On current Base-Sepolia forks the LM reverts with `LOK`. Investigate before relying on `scripts/local_env.sh start` for an unattended setup.

## Gotchas & Tips
@ -50,16 +57,24 @@
- VWAP/ethScarcity logic expects squared price format; do not convert to sqrt unintentionally.
- LiquidityManager `recenter()` reverts unless funded with WETH (Base WETH address `0x4200...006`). Use `cast send` with sufficient ETH when testing locally.
- Ponder’s SQLite store lives in `.ponder/` (gitignored). Delete between runs if schema changes.
- Legacy subgraph still powers `services/txnBot` until cutover—coordinate endpoint switch when Ponder is production-ready.
- `web-app/` currently points at The Graph Studio URLs (see `src/config.ts`). When Ponder replaces the subgraph, update those envs and mirror the expected GraphQL shape (the app queries `stats_collection` with camelCase fields). Consider adding an adapter layer or bumping the frontend to the new schema before deleting `subgraph/`.
- Legacy subgraph is maintained for reference only; all active services now read from Ponder.
- `web-app/` reads from Ponder by default (see `src/config.ts`). Update the environment specific GraphQL URLs when deployments move.

## Refactor Backlog
- Replace the temporary `any` shims in `ponder/src/kraiken.ts` and `ponder/src/stake.ts` by importing the official 0.13 handler types instead of stubbing `ponder-env.d.ts`.
- Drop the custom `ponder:api` / `ponder:registry` module declarations once the generator emits them; if it cannot, declare precise interfaces rather than `any` to keep autocomplete and future upgrades safe.
- Convert the JSON ABI imports in `ponder/ponder.config.ts` to typed loaders (e.g., `satisfies Abi`) so config drift is caught at compile time instead of via `as Abi` casts.
- Move the snatch-selection logic out of `web-app/src/components/StakeHolder.vue` into a dedicated composable that both the stake form and charts can reuse, and memoise the `assetsToShares` conversions there.
- Split `kraiken-lib/src/helpers.ts` into focused modules (ids, tax rates, snatch selection) so consumers can tree-shake and each helper stays small and testable.
## Contacts & Artifacts
