Haskell library and API server for composing balanced Cardano transactions.
You can test Kuber on Cardano testnet via this playground interface : Kuber-Playground. No installation required.
To pay Ada to one or more addresses, you can use compose the following transaction in the playground and execute them using Wallet extension like Nami and Eternl. The UTXOs will be selected using your browser wallet.
{
"outputs": [
{
"address": "addr_test1qrmntnd29t3kpnn8uf7d9asr3fzvw7lnah55h52yvaxnfe4g2v2ge520usmkn0zcl46gy38877hej5cnqe6s602xpkyqtpcsrj",
"value": "10A"
},
{
"address": "addr_test1qpg8r3qvm7qm75p5zjq0c6hj5n2qfw3jp4ppluf7caygyfxv3a6l0p0x9q2e6hjeu62z0g5slxzr4hzjr9x3emnxd5qq65n7xz",
"value": "20A"
}
]
}If you're using Kuber as an API, you'll need to add selections field to indicate the UTXOs to use while composing the transactions. See relevant examples here.

The system packages and dependencies required for building Kuber is the same as that of cardano-node. The steps are described in detail in the documentation of building-cardano-node-from-sources.
In summary, to prepare your system for building kuber from sources, you have to: - install system dependencies for ghc and cardano-node - install ghc compiler and tools with ghcup - install iokhk patch of libsodium on the system
Once everything is installed and ready, kuber will also be ready to run
cabal update
CARDANO_NODE_SOCKET_PATH=/home/user/.cardano/testnet/node.socket cabal run exe:kuber
This will start kuber on port 8081.
