\n\n----------\n\n### Reproduction Steps\n\n1. **Clone the required repositories:**\n \n```bash\ngit clone https://github.com/decenzio/polkadot-sdk.git --branch dev --recurse-submodules\ngit clone https://github.com/decenzio/stick.git\ngit clone https://github.com/decenzio/nft-gallery.git --branch feat/nftaa-support\n```\n \n2. **Install [`just`](https://github.com/casey/just)** for task management.\n \n3. **Start the local Substrate node:**\n \n```bash\ncd polkadot-sdk\njust full\n```\n \n4. **Start backend services:**\n \n```bash\ncd stick\ndocker-compose up\n```\n \n5. **Start the frontend:**\n \n```bash\ncd nft-gallery\npnpm install\npnpm dev\n```\n \n6. **Connect to the chain in Polkadot.js Apps:**\n \n - Go to [https://polkadot.js.org/apps/#/accounts](https://polkadot.js.org/apps/#/accounts)\n \n - In the left menu:\n \n - `Development` > `Custom` > `ws://127.0.0.1:9920`\n \n - Click **Switch**\n \n7. **Fund the test account:**\n \n - Send **1000 UNIT** from `Alice` to your dev wallet.\n \n8. **Create colection and mint NFTAA**\n\n - The collection is created in the standard way as we know in Kodadot and it is similar with the minting of NFTAA into a collection, but when minting the token it is necessary to check the field that it is NFTAA \n----------\n\n### Expected Behavior\n\n- ✅ NFT collections are created correctly.\n \n- ✅ Account system supports UNIT balances.\n \n- ✅ `nftaa.mint` is called properly based on NFT type.\n \n- ✅ Transaction should succeed — as it does via Polkadot.js Apps.\n \n\n----------\n\n### Actual Behavior\n\n- Kodadot's execution of the `batchAll` transaction fails with:\n \n```javascript\n1002: Verification Error: Runtime Error: wasm trap: unreachable\n```\n \n- No NFT is minted.\n\n### Request for Assistance\n\nWe would appreciate any help in identifying what might be going wrong with Kodadot’s handling of the `nftaa.mint` call. Given that the same transaction succeeds in Polkadot.js Apps, we believe the issue lies in Kodadot’s transaction batching or encoding logic.\n\nIf there are known caveats when using `batchAll` or calling custom pallets, or if additional debugging details are needed (e.g. transaction hex, logs, type definitions), we’re happy to provide them.\n\nThanks so much for your help!",[3265,3268],{"name":3266,"color":3267},"external","cfd3d7",{"name":3196,"color":3197},11599,"(Help request) Minting Fails via Kodadot on Local Substrate Chain","2025-08-11T01:37:38Z","https://github.com/kodadot/nft-gallery/issues/11599",0.7665167,["Reactive",3275],{},["Set"],["ShallowReactive",3278],{"$fTRc1wZytZ_XrK4EfJfei_Sz-An4H4Yy6syhVxH_PVJc":-1,"$f3SgE4Cc8ki5VLipLL-XPIF35Jn-0tWLMQJkTVJusqV0":-1},"/kodadot/nft-gallery/3099"]
