Yaci Provider
Custom Cardano devnet to tailor your devnet needs with a builtin indexer and custom viewer for devnet
Yaci DevKit is a development tool designed for rapid and efficient Cardano blockchain development. It allows developers to create and destroy custom Cardano devnets in seconds, providing fast feedback loops and simplifying the iteration process.
Get started:
Get data from URL
You can fetch any data from the blockchain by providing the URL path.
Fetch data from the blockchain
Fetch Account Info
Obtain information about a specific stake account.
Fetch account info using stake address
Fetch Address Assets
Fetch assets from an address.
Fetch UTxOs from address
Fetch assets given an address
Fetch Address UTxOs
Fetch UTxOs controlled by an address.
Optionally, you can filter UTXOs containing a particular asset by providing asset, where it is the concatenation of policy ID and asset.
Fetch UTxOs from address
Fetch UTxOs from address with asset
Fetch Asset Addresses
Fetch a list of a addresses containing a specific asset where it is the concatenation of policy ID and asset.
Fetch list of addresses containing a specific asset
Fetch Asset Metadata
Fetch the asset metadata by providing asset's unit, which is the concatenation of policy ID and asset name in hex.
Fetch metadata from asset ID
Fetch Block Info
Fetch block infomation. You can get the hash from fetchTxInfo().
Fetch information about a block
Fetch Collection Assets
Fetch a list of assets belonging to a collection by providing its Policy ID.
The API will return a list of assets and a cursor next. If the cursor is not null, you can use it to fetch the next page of results. Here is an example of the response.
The fetchCollectionAssets function also accepts an optional cursor parameter to fetch the next page of results. The default value is 1.
Fetch list of assets belonging to a collection and its quantity
Fetch Handle Address
ADA Handle allows users to use a human-readable "Handle" to associate an address.
Each Handle is a unique NFT, minted and issued on the Cardano blockchain. These NFTs act as unique identifiers for the UTXO that they reside in.
We can resolve the handle's address with fetchHandleAddress.
Fetch address by handle
Fetch Handle
ADA Handle allows users to use a human-readable "Handle" to associate an address.
Each Handle is a unique NFT, minted and issued on the Cardano blockchain. These NFTs act as unique identifiers for the UTXO that they reside in.
ADA Handle also released a CIP68 handle and this function will fetch the metadata of the handle.
Fetch handle metadata
Fetch Protocol Parameters
Fetch the latest protocol parameters.
Optionally, you can provide an epoch number to fetch the protocol parameters of that epoch.
Fetch protocol parameters of the blockchain by epoch
Fetch Transaction Info
Fetch transaction infomation. Only confirmed transaction can be retrieved.
Fetch information about a transaction
Fetch UTxOs
Get UTxOs for a given hash.
Optionally, you can specify the index of the index output.
Fetch UTxOs given hash
Fetch Proposal Info
Get information for a given governance proposal, identified by the txHash and proposal index
Fetch Proposals for a given TxHash and certIndex
Evaluate Transaction
evaluateTx() accepts an unsigned transaction (unsignedTx) and it evaluates the resources required to execute the transaction. Note that, this is only valid for transaction interacting with redeemer (smart contract). By knowing the budget required, you can use this to adjust the redeemer's budget so you don't spend more than you need to execute transactions for this smart contract.
Example responses from unlocking assets from the always succeed smart contract.
With the mem and steps, you can refine the budget for the redeemer. For example:
Evaluate the resources required to execute a transaction
Submit Transaction
Submit a serialized transaction to the network.
On Transaction Confirmed
Allow you to listen to a transaction confirmation. Upon confirmation, the callback will be called.
Admin Get Devnet Info
Get information about the devnet.
Example response:
Admin function to get devnet info
Admin Get Genesis Info By Era
You can topup ADA for any address. To topup ADA in your wallet, run the following command from devnet:
Example response:
Admin function to get genesis info by era
Admin Address Topup
You can topup ADA for any address. To topup ADA in your wallet, run the following command from devnet:
Admin function to topup address with ADA
