Cardano URI Parser

A modular, type-safe Cardano URI parser supporting:

✅ CIP-13 (payment + stake URIs) ✅ CIP-99 (claim URIs) ✅ CIP-107 (transaction + block URIs) ✅ CIP-134 (address URIs) ✅ CIP-PR843 (pay URIs) ✅ CIP-PR1058 (browse URIs)

📊 Build & Status

🚀 Supported CIPs

The cardano-uri-parser library currently supports:

| CIP/Authority | Description | |---------------------------|------------------------------------------------------------------------------------------------| | CIP-13 (payment) | Basic Cardano payment URIs (address + amount) | | CIP-13 (stake) | Stake pool delegation URIs | | CIP-99 (claim) | Token claim URIs with faucet references | | CIP-107 (block) | Block URIs by hash or height | | CIP-107 (transaction) | Transaction URIs by hash, with optional output index or metadata references | | CIP-134 (address) | Shelley, Byron (Daedalus, Icarus), mainnet/testnet address URIs with optional stake references | | CIP-PR843 (pay) | Enhanced payment URIs with lovelace, payment ID, note, and native token support | | CIP-PR1058 (browse) | Deep-linking to external dApps (with full URL reconstruction) |

📦 Installation

npm install cardano-uri-parser

✨ Features

• Modular handlers per authority (claim, stake, browse, block, transaction, address, pay)
• Type-safe TypeScript definitions
• Network + era inference: Byron (DdzFF, Ae2), Shelley (addr1, stake1), Testnet (addr_test1)
• Clean parse() (throws on error) and safeParse() (returns null) APIs
• Apache 2.0 licensed

💡 Use Cases

✅ Deep link mobile users directly into:

• dApp pages inside their Cardano wallet
• faucet claims for test tokens or airdrops
• staking delegation flows
• transaction explorers (block, tx, metadata lookup)
• address viewers (including Byron + Shelley, mainnet + testnet)

✅ Generate QR codes for:

• events and conferences
• point-of-sale terminals
• airdrop or promotion campaigns

✅ Validate incoming URIs inside wallet apps

🚀 Quick Example

import {parse, safeParse} from "cardano-uri-parser";

// CIP Pull Request #1058 App Browse URI example
try {
    const result = parse("web+cardano://browse/https/fi.sundae.app/exchange?param=val");
    console.log("Parsed:", result);
} catch (err) {
    console.error("Invalid URI:", err);
}

// CIP-99 Claim URI Example using safeParse
const safeResult = safeParse("web+cardano://claim/v1?faucet_url=https%3A%2F%2Ffaucet.io&code=abc123");

if (safeResult) {
    console.log("Parsed safely:", safeResult);
} else {
    console.log("Invalid or unsupported URI");
}

// CIP-107 Transaction URI Example
try {
    const txResult = parse("web+cardano://transaction/7704a68404facf7126fa356f1b09f0e4c552aeef454cd0daba4208f3a64372e9#1");
    console.log("Parsed transaction:", txResult);
} catch (err) {
    console.error("Invalid URI:", err);
}

// CIP-107 Block URI Example with safeParse (results or returns null)
const safeBlockResult = safeParse('web+cardano://block?height=12345678');

if (safeBlockResult) {
    consol.log("Parsed safely:", safeResult);
} else {
    console.log("Invalid or unsupported URI");
}
