CIP-30 Wallet

Yaci DevKit includes a local CIP-30 wallet for dApp development and SDK testing.

It lets you test browser dApps against a local devnet without installing or configuring a separate browser wallet for every test account.

URLs

When Yaci CLI is running, the wallet tools are served from the CLI/admin port:

The wallet SDK injects this CIP-30 provider:

window.cardano.yacidevkit

Wallet Page

Open the wallet page to inspect local devnet accounts, switch the active account used by dApps, import accounts, and send test transactions.

http://localhost:10000/wallet

The default DevKit mnemonic is used for the pre-funded local accounts:

test test test test test test test test test test test test test test test test test test test test test test test sauce

Use From a dApp

Include the SDK in your local dApp page:

<script src="http://localhost:10000/wallet-sdk.js"></script>

Then use it like any other CIP-30 wallet:

const wallet = await window.cardano.yacidevkit.enable();
 
const networkId = await wallet.getNetworkId();
const balance = await wallet.getBalance();
const changeAddress = await wallet.getChangeAddress();

Supported CIP-30 Methods

The wallet SDK supports the common CIP-30 flow used by local dApps:

• isEnabled()
• enable()
• getNetworkId()
• getBalance()
• getUtxos()
• getUsedAddresses()
• getUnusedAddresses()
• getChangeAddress()
• getRewardAddresses()
• getCollateral()
• signTx()
• signData()
• submitTx()

Transaction Flow

For transfer and dApp signing flows:

• wallet data is exposed through CIP-30-compatible CBOR values
• transaction signing happens through the CLI wallet backend
• UTxO and balance queries use Yaci Store when required
• signed transaction submission is proxied through the local DevKit services

Examples

The packaged examples/ folder includes browser examples that use CIP-30:

• examples/wallet-demo: wallet discovery, CIP-30 methods, signing, and transfer flow
• examples/meshjs-mint-nft: NFT minting with MeshJS and CIP-30 signing

Both Docker and native CLI zip distributions include these examples.

Run info in Yaci CLI to see the active wallet page and SDK URLs for your devnet.
