\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!",[3236,3239],{"name":3237,"color":3238},"external","cfd3d7",{"name":3240,"color":3190},"$$",11599,"(Help request) Minting Fails via Kodadot on Local Substrate Chain","2025-08-11T01:37:38Z","https://github.com/kodadot/nft-gallery/issues/11599",0.7608384,{"description":3247,"labels":3248,"number":3252,"owner":3146,"repository":3160,"state":3161,"title":3253,"updated_at":3254,"url":3255,"score":3256},"Till user stares at finishing their buy into Blockchain, would be nice to maintain contact with them in reasonable way, like fun facts about NFTs is probably cheapest hack\n\nSimilar like Disocrd tricks you while they loading app in the background.\n\nIt should be extended preloader component and fetch quotes from translations in random fashion.\n\nLet me take first round.
