Getting Started

After including the file saseul.min.js in your project, please follow:

<script src="saseul.min.js"></script>
<script type="text/javascript">
    SASEUL.Rpc.send(
        SASEUL.Rpc.request(
            {
                type: "GetBalance",
                address: "f8df34871e7d7d4b4bcb948fd41e0d4a362a6398043e",
            }
        ), "https://main.saseul.net"
    ).then(function (r) { console.dir(r); });
</script>

You can see the following results on the console.

{"code":200,"data":{"balance":"0"}}

Making address

SASEUL use ed25519, ripemd160, sha256 algorithm to make private key, public key, address. Ed25519 is used to generate key pairs. You can hash the public key generated by the ed25519 algorithm as follows to generate an address.

address = ID_HASH(public_key)

ID_HASH = SHORT_HASH + CHECKSUM

CHECKSHUM = SHA256(SHA256(SHORT_HASH)).SUBSTRING(0,4)

SHORT_HASH = RIPEMD160(SHA256(public_key))

Making transaction, request

“transaction” changes the status of the network. All transactions are computed by a predefined smart contract code.

“request” queries the status of the network. All requests are also computed by a predefined smart contract code.

SASEUL.Rpc.transaction

Example

var obj = SASEUL.Rpc.transaction(
    {
        type: "Send",
        to: "f8df34871e7d7d4b4bcb948fd41e0d4a362a6398043e",
        amount: "1"
    }, // Transaction object
    'bbbdd1f301b5ab75deba2a6968e1e565eb9022102565e7cfa1169660dc0e2780' // private key
);

Search for Peers

SASEUL Public Network will probably contain the following three addresses:

• main.saseul.net
• aroma.saseul.net
• blanc.saseul.net

Test Network (Americano) will probably contain the following address:

• test.saseul.net

If you want to know the address of the custom network, the default address of the custom network will be provided by the creator of the custom network.

SASEUL.Rpc.searchPeers

Example

var obj = SASEUL.Rpc.request(
    {

        address: "f8df34871e7d7d4b4bcb948fd41e0d4a362a6398043e",
    }
);

SASEUL.Rpc.searchPeers(
    [
        "https://main.saseul.net",
