\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!",[],11599,"kodadot","nft-gallery","open","(Help request) Minting Fails via Kodadot on Local Substrate Chain","2025-07-23T23:32:21Z","https://github.com/kodadot/nft-gallery/issues/11599",0.7665167,{"description":3028,"labels":3029,"number":3044,"owner":3020,"repository":3021,"state":3045,"title":3046,"updated_at":3047,"url":3048,"score":3049},"\r\n\r\n\r\nWe would like softly introduce EVM compatibility to KodaDot and I guess this is a fair opportunity to extend KodaDot on MoonRiver. \r\nChain selector could stay for \"MoonSama\" in this case as thinking of broad support of rest of EVM would require a fair amount of time than we have for this submission, till 10/7 (reserve 1 day).\r\n\r\nWe have approximately 25 more days to submit. \r\nRight now we aim to deliver RO version first and then we can extend for RW, like adding support for EVM wallets and EVM actions\r\n\r\n### What would need to be done?\r\n#### Read-only\r\nAll of the following would be made into smaller issues\r\n- spin up EVM SubSquid \r\n - #3176\r\n - #3177\r\n - kodadot/click#17\r\n- The whole explorer adjusts to see NFTs from a particular contract\r\n - #3178 \t\r\n- See current and historical floor price (adjust chart engine)\r\n - https://github.com/kodadot/nft-gallery/issues/3179 \r\n- Adjust the holder's chart to feed data there\r\n - #3180 \r\n- Sort by rarity in explorer\r\n - #3181\r\n- In the user's profile adjust the showing holdings per user (holdings) table\r\n - #3182\r\n- history chart for collection adjust feeding data there\r\n - #3183 \r\n- flippers in collection\r\n- collection images\r\n- https://github.com/kodadot/nft-gallery/issues/3388 \r\n\r\n#### Write ops \r\n- EVM actions over NFT item\r\n- support EVM wallet\r\n- what else?\r\n\r\n\r\nWho will \r\n### Ref\r\n- https://github.com/subsquid/bounties/issues/3\r\n- https://devpost.com/software/kodadot-moonsama\r\n- https://docs.subsquid.io/reference/evm-processor\r\n- https://docs.subsquid.io/reference/squid-evm-typegen\r\n- https://docs.subsquid.io/tutorial/create-an-evm-processing-squid\r\n- https://docs.subsquid.io/tutorial/create-an-evm-processing-squid#define-and-bind-event-handler-s\r\n- https://marketplace.moonsama.com/collections",[3030,3033,3036,3039,3042],{"name":3031,"color":3032},"p2","D4C5F9",{"name":3034,"color":3035},"A-subsquid","FBCA04",{"name":3037,"color":3038},"chief","67EA1F",{"name":3040,"color":3041},"moonsama","49A4B2",{"name":3043,"color":3035},"A-moonriver",3161,"closed","Moonsama integration v0 ","2022-09-01T12:32:46Z","https://github.com/kodadot/nft-gallery/issues/3161",0.72053397,{"description":3051,"labels":3052,"number":3057,"owner":3020,"repository":3021,"state":3045,"title":3058,"updated_at":3059,"url":3060,"score":3061},"I guess once will be RMRK 2.0 reader is merged, we can kick off implementing RMRK 2.0 \r\n\r\nRight now probably, we will need to prepare components there to be ready :)\r\n\r\nAs many collections migrated from RMRKv1 to RMRKv2 for their own needs/reasons or pushed by Singular authors for their needs to extend with equipable, we would like to keep up showing content in KodaDot for better comfort of one place showing many NFT standards.\r\n\r\n### Ref\r\n- https://github.com/kodadot/packages/pull/43",[3053,3054,3055],{"name":3031,"color":3032},{"name":3037,"color":3038},{"name":3056,"color":3035},"A-rmrk",4013,"RMRKv2 implementation","2023-01-18T12:23:16Z","https://github.com/kodadot/nft-gallery/issues/4013",0.7437743,{"description":3063,"labels":3064,"number":3070,"owner":3020,"repository":3021,"state":3045,"title":3071,"updated_at":3072,"url":3073,"score":3074},"Add to faq\r\n\r\n\"We've been long working with https://bsx.fi team to have working **royalties, make an offer and accept an offer** for creators.

Simple as that. Even we are running on a low carbon blockchain Kusama.network and plan to roll out our own NFT-focused infrastructure parachain Metaprime.network, we feel that we should step up in the game and be more carbon neutral and later contribute to be carbon negative in a way to drive global forestation. To help artists mitigate the negative effects of expanding society on the planet. At least, we might contribute to do the small job here. The audience will decide.\r\n\r\n### Carbon Neutral Mission of Kodadot\r\nThe mission of Kodadot gallery is to flow collectors' resources to environmentally conscious digital art creation in a way to address the Earth's mounting climate crisis. We have intent to bring [carbon calculator](https://github.com/kodadot/nft-gallery/issues?q=is%3Aissue+label%3Acarbonless) and help to make forestations and offsetting as new normal and easy access. To kick-start this effort, we've partnered with Offsetra which allows users to support \"high-quality pro-climate projects via the purchase of carbon offsets credits\". \r\nCarbon offset credits come from a variety of sustainability-oriented projects. Offsetra only sources offsets from validated and verified projects under strict internationally recognized standards. You can find more information on offsetra's process is available [on their website](https://offsetra.com/)\r\n\r\n### Humble actions\r\nWe are aware that just by purchasing Carbon Offsets we won't solve the issue, but we can be small butterfly effect, and later jumpstart impactful actions to start a movement, where it would be native for NFT galleries to bring with every mint, buying offsets in a way to put a small amount of % towards buying carbon offsets and forestation.\r\n\r\nWe will try to put at least some amount of artists' profits based on their decision to drive towards buying credit offsets. Not just feel good about, but with a real impactful way to do it. \r\n\r\n### Building impactful environmental relief\r\nOur first start is to add a toggle to our minting interface where every artist could choose if they want to support carbon credits or not. We will be adding the **carbonless** tag to NFT and later it could be tracked through the search interface and reviewed on-chain. Thus collectors might find it innovative to collect carbonless NFTs. \r\n\r\nOnce Offsetra (or other carbon credit partners) figure out a way to make fiat off-ramp payments from Kusama for carbon-offsets to happen, we will make a full end-to-end native crypto integration with them, so every NFT will consist hash relying on Carbon Credit. \r\n\r\nTo drive the vision to home, we are genuinely looking forward to starting with [Terraformation of Planet Earth](https://yangwao.medium.com/planet-terraformation-forest-as-a-service-94a2633ad011) where one could participate in fashion to own part of the forest, probably introduce the concept of **Forest as a Service**. Imagination is the limit.\r\n\r\n### We are not only one and that's great\r\nWe are really aware that movement is just about to begin when news outlets started heating discussion and [clean #cleanNFT movement ](https://twitter.com/search?q=%23CleanNFT&src=typeahead_click) has begun. One option for the creator is to [choose from a variety of NFT platforms running on low carbon blockchains](https://docs.google.com/spreadsheets/d/1A-7Ama31sYWhXDl6NoJaXnbAV9pFbjxLIgl7jb3CHOs/edit#gid=0) which is really great start. Another option is to actively drive movement to be [carbon-negative gallery](https://offsets.gallery/). So we (Kodadot) are feeling inspired to join this movement in our fashioned way **to add carbonless minting for creators** and start showing which NFTs are carbonless by showing 🌱 next. Link na carbonless NFT. To top-up our buffer carbon credits, we've already bought Carbon Credits and plan to buy more in favour of KodaDot NFTs. \r\n\r\n\r\n### Reading list\r\nThere are current other partners to help us in this way \r\nThere are current other partners to help us in this way \r\n- https://www.cloverly.com/\r\n- https://offsetra.com/\r\n- https://www.wired.com/story/nfts-hot-effect-earth-climate/\r\n- https://earther.gizmodo.com/how-to-fix-crypto-art-nfts-carbon-pollution-problem-1846440312\r\n- https://www.artnome.com/greennfts\r\n- https://docs.google.com/spreadsheets/d/1WJE9kr5PWpIhHygrRBetmokBVpc78RzAddeLSAV878M/edit#gid=0\r\n- https://docs.google.com/spreadsheets/d/1A-7Ama31sYWhXDl6NoJaXnbAV9pFbjxLIgl7jb3CHOs/edit#gid=0\r\n- https://gitcoin.co/hackathon/green-nft/onboard\r\n- https://gitcoin.co/hackathon/green-nft/projects/\r\n- https://near.org/blog/near-climate-neutral-product/\r\n- https://medium.com/tqtezos/proof-of-work-vs-proof-of-stake-the-ecological-footprint-c58029faee44\r\n- https://sterlingcrispin.blogspot.com/2021/02/crypto-art-sky-is-not-falling.html\r\n- Kodadot: Carbonless Minting Telegram - https://t.me/joinchat/aE-i3mgMAo9lMTU0\r\n\r\n### page\r\nprobably change it from > Low carbon NFT platform running on Kusama.network - NPoS \r\nCarbonless NFT platform running on Kusama.network & Metaprime.network.\r\n\r\n#### Misc\r\n- solution bounty https://github.com/artnome/GreenNFTs/issues/2\r\n- awareness bounty https://github.com/artnome/GreenNFTs/issues/4\r\n- Tezos carbon-negative NFT marketplace https://github.com/artnome/GreenNFTs/issues/3\r\n\r\n##### Carbon Credits\r\nQuantity of retired VCU: 10\r\nSerial numbers: 9956-166792555-166792564-VCS-VCU-352-VER-BZ-14-812-01012009-31122009-0\r\nDate of retirement: 5/3/2021 2:55:52 PM\r\nBeneficial Owner: KodaDot\r\nRetirement reason details: Retirement for Person or Organization; Offsetra Offset\r\nPublic URL: https://registry.verra.org/myModule/rpt/myrpt.asp?r=206&h=131130\r\n\r\nBull Run Overseas Forest Carbon Project\r\nProject type: Agriculture Forestry and Other Land Use\r\nProject country: BZ\r\n\r\n\r\n",[3115],{"name":3116,"color":3117},"carbonless","45D52D",346,"[Solutions Bounty] Mint carbonless NFTs on Kusama network","2021-05-07T13:34:44Z","https://github.com/kodadot/nft-gallery/issues/346",0.76466185,{"description":3124,"labels":3125,"number":3127,"owner":3020,"repository":3021,"state":3045,"title":3128,"updated_at":3129,"url":3130,"score":3131},"We will slowly start iterate to add carbonless NFTs to the KodaDot\r\n\r\nWe've created an address from whom we will be buying carbon offsets in favour of NFT creators\r\nJ9PSLHKjtJ9eEAX4xmCe8xNipRxNiYJTbnyfKXXRkhMmuq8 till we figure out how can artists can buy them in their fashioned way.\r\n\r\nThus you will see toggle while minting NFT\r\nWhat will happen, we will add the attribute that NFT was covered by carbon credits, probably marking you NFTs as carbonless\r\nWe are still estimating hard numbers so we set something which for sure should cover your carbon credits\r\n\r\nRight now we decided to go with at least with $1 as we are running on low carbon chain, Kusama network, later we can estimate against past mints what leverage they bought in carbon credits.",[3126],{"name":3116,"color":3117},350,"Add toggle to mint green carbonless NFTs ","2021-05-07T13:30:29Z","https://github.com/kodadot/nft-gallery/issues/350",0.7647353,{"description":3133,"labels":3134,"number":3140,"owner":3020,"repository":3021,"state":3045,"title":3141,"updated_at":3142,"url":3143,"score":3144},"We would need to build a developer audience around kodadot and show them how easy is to write your own resolver to the Rubick\r\n\r\n- write an easy SubSquid query \r\n- Leverage the usefulness of Viki's tutorial, in a simple format, hence video is 1 hour long \r\n- I guess we can publish it to dev.to as there is better developer audience \r\n\r\n### Ref\r\n- https://github.com/kodadot/rubick/\r\n- \r\n",[3135,3136,3137,3138],{"name":3079,"color":3080},{"name":3082,"color":3032},{"name":3034,"color":3035},{"name":3139,"color":3035},"A-writing-✍️",3042,"how to make NFT resolver to Rubick and use it in KodaDot ","2023-12-22T10:58:53Z","https://github.com/kodadot/nft-gallery/issues/3042",0.7658407,["Reactive",3146],{},["Set"],["ShallowReactive",3149],{"$fTRc1wZytZ_XrK4EfJfei_Sz-An4H4Yy6syhVxH_PVJc":-1,"$f3SgE4Cc8ki5VLipLL-XPIF35Jn-0tWLMQJkTVJusqV0":-1},"/kodadot/nft-gallery/3099"]
