CIPs are standards, not implementations\n\nA CIP defines a specification or convention. It does not provide a library or runtime. SDKs\nand tools choose to implement CIPs. When explaining a CIP, distinguish between what the\nstandard defines and how specific tools implement it.\n\n### 2. Always check CIP status\n\nCIPs go through lifecycle stages: Draft, Proposed, Active, Inactive. A Draft CIP may change\nsignificantly. An Active CIP is stable and widely adopted. Always note the status when\nexplaining a CIP, because developers should not build on unstable drafts without\nunderstanding the risk.\n\n### 3. Focus on developer impact\n\nDevelopers care about: What does this CIP let me do? What do I need to implement? Which\nSDKs support it? What are the constraints? Lead with practical impact, not governance\nprocess.\n\n### 4. CIPs build on each other\n\nMany CIPs reference or extend others. CIP-68 builds on CIP-25 concepts. CIP-95 extends\nCIP-30. When explaining a CIP, note its dependencies and related CIPs so the developer\nunderstands the full picture.\n\n## Workflow\n\n### Step 1: Identify the CIP\n\nDetermine the CIP number from the developer's question. If they describe a feature without\nnaming a CIP, map it:\n- \"NFT metadata\" -> CIP-25, CIP-68\n- \"Wallet connection\" -> CIP-30\n- \"Governance wallet\" -> CIP-95\n- \"Token metadata on-chain\" -> CIP-68\n- \"Validator blueprint\" -> CIP-57\n- \"Programmable tokens\" -> CIP-113\n- \"On-chain governance\" -> CIP-1694\n\n### Step 2: Search Bundled Documentation\n\nSearch the bundled documentation for relevant content:\n- `..\u002F..\u002Fdocs\u002Fsources\u002Fcips\u002F` - CIP specifications and proposals\n\nSearch the local files for relevant content. CIP material may appear in reference docs,\nregistry entries, or skill files.\n\n### Step 3: Explain the CIP\n\nStructure your explanation with these components:\n\n**Summary:** One-paragraph description of what the CIP standardizes.\n\n**Motivation:** Why was this CIP created? What problem does it solve? What existed before?\n\n**Developer impact:** What does this mean for a developer building on Cardano?\n- What can they build with it?\n- What do they need to implement?\n- What constraints does it impose?\n\n**Implementation status:** Is this CIP Active, Draft, or Proposed? Which SDKs support it?\nAre there known limitations or upcoming changes?\n\n**SDK support:** Which Cardano SDKs and tools implement this CIP, and how?\n\n### Step 4: Provide practical guidance\n\nGive the developer actionable next steps:\n- Point to the relevant skill if they need to implement something\n- Note which SDK methods or tools to use\n- Highlight common pitfalls or misunderstandings\n\n## Key CIPs for Developers\n\n### CIP-25: Media Token Metadata Standard\n\n**Status:** Active\n\n**Summary:** Defines a standard for attaching metadata to media tokens\u002FNFTs using\ntransaction metadata (label 721). Metadata is included in the minting transaction and\nindexed by off-chain services. (For fungible-token metadata — ticker, decimals, logo —\nthe standard path is CIP-26, the off-chain token registry, not CIP-25.)\n\n**Developer impact:**\n- Metadata is stored in the transaction, not on the UTxO itself\n- Metadata lives in minting transactions. It is fixed once the minting policy closes;\n  while the policy is open, a later mint carrying label 721 replaces it\n- Off-chain indexers (Blockfrost, Koios, etc.) parse and serve CIP-25 metadata\n- Simple to implement: add a metadata entry to the minting transaction\n\n**Limitations:**\n- Updatable only by minting again under an open policy, so no updates once the policy closes\n- Stored off-chain relative to the UTxO (only in the transaction)\n- Led to the creation of CIP-68 to address mutability and on-chain storage\n\n**Structure:**\n```json\n{\n  \"721\": {\n    \"\u003Cpolicy_id>\": {\n      \"\u003Casset_name>\": {\n        \"name\": \"Token Name\",\n        \"image\": \"ipfs:\u002F\u002F\u003Chash>\",\n        \"description\": \"Token description\",\n        \"mediaType\": \"image\u002Fpng\",\n        \"\u003Cadditional_properties>\": \"...\"\n      }\n    }\n  }\n}\n```\n\n### CIP-30: Cardano dApp-Wallet Web Bridge\n\n**Status:** Active\n\n**Summary:** Defines a JavaScript API that wallets inject into web pages, enabling dApps to\nrequest wallet information, build transactions, and request signing. This is the primary\nstandard for dApp-wallet interaction in browsers.\n\n**Developer impact:**\n- `window.cardano.\u003CwalletName>` exposes the wallet API\n- `enable()` returns an API object with methods for address, UTxO, and signing operations\n- All data is CBOR-encoded — SDKs handle serialization\n- Wallets: Begin, Eternl, GeroWallet, Lace, NuFi, RayWallet, Yoroi all implement CIP-30\n\n**Key API methods:**\n- `getNetworkId()` — returns 0 (testnet) or 1 (mainnet)\n- `getUtxos()` — returns available UTxOs for transaction building\n- `getBalance()` — returns wallet balance\n- `getUsedAddresses()` \u002F `getUnusedAddresses()` — address management\n- `signTx(tx, partialSign)` — request transaction signing\n- `signData(addr, payload)` — sign arbitrary data (CIP-8)\n- `submitTx(tx)` — submit a signed transaction\n\n**Common pitfalls:**\n- Always check `window.cardano` exists before accessing wallet properties\n- Handle the case where the user rejects the `enable()` prompt\n- CBOR encoding\u002Fdecoding — use an SDK (Mesh, Evolution SDK) rather than raw CIP-30\n\n### CIP-57: Plutus Contract Blueprint (CIP-0057)\n\n**Status:** Active\n\n**Summary:** Defines a JSON schema (blueprint) for Plutus validators, describing their\nparameters, datum, and redeemer types. Aiken generates CIP-57 blueprints automatically.\nSDKs use blueprints to create type-safe interfaces for validator interaction.\n\n**Developer impact:**\n- Aiken produces `plutus.json` after compilation — this is the CIP-57 blueprint\n- SDKs (Mesh, Evolution SDK) can read the blueprint to generate typed transaction\n  builders\n- Blueprints enable code generation and type safety across the on-chain\u002Foff-chain boundary\n- Includes validator hashes, parameter schemas, and datum\u002Fredeemer definitions\n\n**Structure highlights:**\n- `validators[]` — list of validators with their hashes and compiled code\n- `definitions` — shared type definitions (datum, redeemer schemas)\n- Each validator entry includes `datum.schema`, `redeemer.schema`, and `compiledCode`\n\n### CIP-68: Datum Metadata Standard\n\n**Status:** Active\n\n**Summary:** Defines a pattern for storing token metadata as a datum on a reference UTxO,\nmaking metadata on-chain, updatable, and queryable via reference inputs. Replaces CIP-25\nfor use cases requiring mutable or on-chain metadata.\n\n**Developer impact:**\n- Each token has a paired reference NFT holding metadata in its datum\n- Token labels: `(222)` for NFTs, `(333)` for FTs, `(444)` for RFTs\n- The reference NFT sits at a script address; the user token is in the user's wallet\n- Metadata can be updated by consuming and recreating the reference UTxO\n- Requires a more complex minting policy than CIP-25\n\n**Architecture:**\n- **User token:** `\u003Cpolicy_id>.\u003Clabel>\u003Cname>` — held by the owner, represents ownership\n- **Reference token:** `\u003Cpolicy_id>.(100)\u003Cname>` — held at a script address, carries\n  metadata in its datum (label 100, hex prefix `000643b0`)\n- The minting policy enforces that both tokens are minted together\n\n**When to use CIP-68 vs CIP-25:**\n| Requirement | CIP-25 | CIP-68 |\n|---|---|---|\n| Simple, immutable NFT | Good fit | Overkill |\n| Updatable metadata | Not possible | Designed for this |\n| On-chain metadata access | Not available | Via reference input |\n| Implementation complexity | Low | Medium |\n| Transaction cost | Lower (metadata only) | Higher (reference UTxO + datum) |\n\n### CIP-95: Governance Wallet Extensions\n\n**Status:** Active (Conway era)\n\n**Summary:** Extends CIP-30 with governance-specific wallet methods for the Conway\ngovernance era (Voltaire). Enables dApps to interact with DRep registration, voting, and\ngovernance actions.\n\n**Developer impact:**\n- Adds `cip95` methods accessible after `enable({ extensions: [{ cip: 95 }] })`\n- `getPubDRepKey()` — get the wallet's DRep public key\n- `getRegisteredPubStakeKeys()` — get registered stake keys\n- `getUnregisteredPubStakeKeys()` — get unregistered stake keys\n- Required for governance dApps (GovTool, DRep platforms)\n\n**Prerequisite:** CIP-30 wallet connection must be established first.\n\n### CIP-113: Programmable Tokens\n\n**Status:** Proposed, merged into the CIPs repository through\n[cardano-foundation\u002FCIPs#444](https:\u002F\u002Fgithub.com\u002Fcardano-foundation\u002FCIPs\u002Fpull\u002F444).\nThe specification is at `..\u002F..\u002Fdocs\u002Fsources\u002Fcips\u002FCIP-0113\u002FREADME.md`; the reference\nimplementation is bundled under `..\u002F..\u002Fdocs\u002Fsources\u002Fcip-113-programmable-tokens\u002F`.\n\n**Summary:** Defines a standard for tokens with programmable validation logic — rules\nenforced on every transfer, mint, and burn. Tokens are held at a shared script address\nwith ownership tracked by stake credential; an on-chain registry links each token to its\ntransfer\u002Fissuance logic, and modules (freeze-and-seize, KYC) plug into the shared\nframework.\n\n**Developer impact:**\n- Enables \"smart tokens\" with enforced transfer rules (regulated assets, stablecoins)\n- Shared-custody model: wallets\u002FDEXes need stake-credential-aware integration\n- Relevant for compliance-bound assets; plain minting policies remain right for most tokens\n\n**Note:** The Cardano Foundation's core on-chain framework has been professionally\naudited, with each finding resolved or acknowledged as a residual design limitation; an\naudit does not by itself make a deployment safe. The modules and the off-chain platform\nhave not been audited, and have been tested only on the Preview testnet. The READMEs of\n`..\u002F..\u002Fdocs\u002Fsources\u002Fcip-113-programmable-tokens\u002F` and\n`..\u002F..\u002Fdocs\u002Fsources\u002Fcip-113-programmable-tokens-platform\u002F` for each repository's audit status.\n\n### CIP-1694: Conway Era Governance (Voltaire)\n\n**Status:** Active\n\n**Summary:** Defines Cardano's on-chain governance system introduced in the Conway era.\nEstablishes the governance framework with DReps (Delegated Representatives), a\nConstitutional Committee, and SPO governance roles. All holders can participate in governance\nthrough delegation or direct voting.\n\n**Developer impact:**\n- Governance actions are on-chain transactions (parameter changes, treasury withdrawals,\n  hard forks, constitutional committee updates, motions of no confidence)\n- DRep registration and voting use specific transaction certificate types\n- SDKs need Conway-era transaction support for governance features\n- dApps can integrate governance features using CIP-95 wallet extensions\n\n**Key concepts:**\n- **DRep:** A delegated representative who votes on governance actions\n- **Constitutional Committee:** A group that checks governance actions against the constitution\n- **Governance action:** A proposal submitted on-chain with a deposit\n- **Ratification:** The process by which DReps, SPOs, and the Constitutional Committee\n  approve or reject actions\n\n## Mapping Topics to CIPs\n\nWhen a developer describes a feature, map it to the relevant CIP:\n\n| Developer asks about... | Relevant CIP(s) |\n|---|---|\n| NFT metadata | CIP-25 (updatable only by re-minting), CIP-68 (updatable) |\n| Wallet connection | CIP-30 |\n| Wallet governance | CIP-95 (extends CIP-30) |\n| Message signing | CIP-8 (via CIP-30's `signData`) |\n| Token metadata on-chain | CIP-68 |\n| Validator interface \u002F types | CIP-57 (blueprint) |\n| Programmable tokens | CIP-113 |\n| Governance \u002F voting | CIP-1694 |\n| Reference inputs | CIP-31 |\n| Inline datums | CIP-32 |\n| Reference scripts | CIP-33 |\n| Collateral outputs | CIP-40 |\n| Multi-asset structure | CIP-14 (asset fingerprint) |\n\n## References\n\n- CIP repository: `github.com\u002Fcardano-foundation\u002FCIPs`\n- Shared principles: `..\u002F..\u002Fdocs\u002FSKILL_PRINCIPLES.md`\n","> Resolve `..\u002F..\u002Fdocs\u002Fsources\u002F` relative to this `SKILL.md`, never from the user’s working directory.

All holders can participate in governance\nthrough delegation or direct voting.\n\n**Developer impact:**\n- Governance actions are on-chain transactions (parameter changes, treasury withdrawals,\n  hard forks, constitutional committee updates, motions of no confidence)\n- DRep registration and voting use specific transaction certificate types\n- SDKs need Conway-era transaction support for governance features\n- dApps can integrate governance features using CIP-95 wallet extensions\n\n**Key concepts:**\n- **DRep:** A delegated representative who votes on governance actions\n- **Constitutional Committee:** A group that checks governance actions against the constitution\n- **Governance action:** A proposal submitted on-chain with a deposit\n- **Ratification:** The process by which DReps, SPOs, and the Constitutional Committee\n  approve or reject actions\n\n## Mapping Topics to CIPs\n\nWhen a developer describes a feature, map it to the relevant CIP:\n\n| Developer asks about... | Relevant CIP(s) |\n|---|---|\n| NFT metadata | CIP-25 (updatable only by re-minting), CIP-68 (updatable) |\n| Wallet connection | CIP-30 |\n| Wallet governance | CIP-95 (extends CIP-30) |\n| Message signing | CIP-8 (via CIP-30's `signData`) |\n| Token metadata on-chain | CIP-68 |\n| Validator interface \u002F types | CIP-57 (blueprint) |\n| Programmable tokens | CIP-113 |\n| Governance \u002F voting | CIP-1694 |\n| Reference inputs | CIP-31 |\n| Inline datums | CIP-32 |\n| Reference scripts | CIP-33 |\n| Collateral outputs | CIP-40 |\n| Multi-asset structure | CIP-14 (asset fingerprint) |\n\n## References\n\n- CIP repository: `github.com\u002Fcardano-foundation\u002FCIPs`\n- Shared principles: `..\u002F..\u002Fdocs\u002FSKILL_PRINCIPLES.md`\n",{"name":5,"description":7,"allowed-tools":46,"disallowed-tools":47},"Read Grep Glob","Bash Edit Write WebFetch WebSearch","main","3df1d0d67b30ff15236561f8c0f9f06d33f42dfd","skills\u002Fchains\u002Fcardano-foundation-explain-cip",17,"https:\u002F\u002Fgithub.com\u002Fjiayaoqijia\u002Fcryptoskill","https:\u002F\u002Fgithub.com\u002Fjiayaoqijia","https:\u002F\u002Feth2030.com","Hardcore infra.
