The token's launch status must still be `PRE_LAUNCH`. Every transaction in the bundle must be co-signed by `wallet` before submission; see the bundle item `type` for submission order (`LUT_SETUP` and `CREATE_TOKEN` first, then `LAUNCH`, then optionally `LUT_DEACTIVATE`/`LUT_CLOSE`). ## Submission order The response bundle can contain up to five transactions. Submit them in this order: 1. **`LUT_SETUP`** and **`CREATE_TOKEN`** — independent; submit both (in parallel is fine) and wait for both to confirm. `LUT_SETUP` creates the address lookup table `LAUNCH` depends on; a lookup table is only usable starting the slot *after* it is extended, so confirming this before submitting `LAUNCH` is required. `CREATE_TOKEN` is omitted from the bundle on rebuilds where the mint already landed on-chain. 2. **`LAUNCH`** — atomic: initializes the pool, deposits both locked positions, and executes the optional initial buy. Trading is live the moment this lands. If the first submission races the lookup-table warmup, retry once the table has warmed up. 3. **`LUT_DEACTIVATE`** — deactivates the lookup table. Submit only after `LAUNCH` confirms. Carries no server signature — replace `recentBlockhash` with a fresh one right before signing. 4. **`LUT_CLOSE`** (optional) — reclaims the lookup table rent. Only valid for a window starting shortly after `LUT_DEACTIVATE`. Carries no server signature — replace `recentBlockhash` with a fresh one right before signing. Every transaction must be co-signed by `wallet`. If the bundle's blockhash expires before `LAUNCH` lands, request a new bundle rather than resubmitting — nothing partial is left on-chain. ## OpenAPI ````yaml POST /token-launch/damm-v2/create-transaction openapi: 3.1.0 info: title: Bags Public API v2 description: API endpoints for Bags platform version: 2.0.0 contact: name: Bags Support url: https://support.bags.fm servers: - url: https://public-api-v2.bags.fm/api/v1 description: Production server security: - ApiKeyAuth: [] tags: - name: Token Launch description: Endpoints for creating and managing token launches - name: Fee Share description: Endpoints for managing fee sharing configs - name: Fee Share Admin description: >- Endpoints for fee share admin operations including listing, transferring admin authority, and updating configs - name: Analytics description: Endpoints for retrieving token analytics and metadata - name: Fee Claiming description: Endpoints for claiming fees from various sources - name: State description: Endpoints for retrieving on-chain state and derived state - name: Trade description: Endpoints for getting trade quotes and executing token swaps - name: Partner description: Endpoints for managing partner configurations and claiming partner fees - name: Solana description: Endpoints for direct Solana blockchain interactions - name: EVM description: Endpoints for reading Bags EVM token data - name: Robinhood Chain description: Read endpoints for Bags V2 tokens on Robinhood Chain (chain id 4663) - name: Dexscreener description: >- Endpoints for managing Dexscreener token info orders, payments, and image uploads - name: Auth description: Endpoints for retrieving authenticated user information - name: Agent description: Endpoints for AI agent wallet-signature authentication (V2) paths: /token-launch/damm-v2/create-transaction: post: tags: - Token Launch summary: Create DAMM v2 direct launch transaction description: >- Builds the partially-signed transaction bundle that launches a token previously registered via `POST /token-launch/create-token-info` straight into a single-sided DAMM v2 customizable pool (no DBC bonding curve, no migration).
