​
Private Key Parsing

​
Usage

var jsonConfig = "";
var ji = JsonIterator.parse(jsonConfig);
var signer = PrivateKeyEncoding.fromJsonPrivateKey(ji);

​
JSON Configuration

If the base58 encoded public key is configured via pubKey it will be used to further validate the public key derived from the private key.

​
Solana CLI Key Pair JSON Array

By default, if only an array is configured, the assumption is that it is a key pair generated by the Solana CLI.

[1,2,3, ... ,42]

​
JSON Array

{
  "pubKey": "<BASE58_ENCODED_PUBLIC_KEY>",
  "encoding": "jsonKeyPairArray",
  "secret": []
}

​
Key Pair

Encoded 64 byte private/public key pair. Derived public key will be validated.

  • base64KeyPair
  • base58KeyPair
{
  "pubKey": "<BASE58_ENCODED_PUBLIC_KEY>",
  "encoding": "base64KeyPair",
  "secret": "asdf=="
}

​
Private Key Only

Encoded 32 byte private key.

  • base64PrivateKey
  • base58PrivateKey
{
  "pubKey": "<BASE58_ENCODED_PUBLIC_KEY>",
  "encoding": "base64PrivateKey",
  "secret": "asdf=="
}

​
Transaction Deserialization

The TransactionSkeleton interface provides a lightweight view over transaction data. Allowing for partial introspection or complete reconstruction of a Transaction.

​
Legacy

byte[] legacyTransactionData = ...;
var skeleton = TransactionSkeleton.deserializeSkeleton(legacyTransactionData);
AccountMeta[] accounts = skeleton.parseAccounts();
Instruction[] instructions = skeleton.parseLegacyInstructions();
Transaction transaction = skeleton.createTransaction()

​
Versioned

byte[] v0TransactionData = ...;
var skeleton = TransactionSkeleton.deserializeSkeleton(v0TransactionData);
var instructionsWithoutTableAccounts = skeleton.parseInstructionsWithoutTableAccounts();

PublicKey[] tableAccounts =  skeleton.lookupTableAccounts();
// ... Fetch table accounts (See RPC) ...
AddressLookupTable lookupTable = ...;
AccountMeta[] accounts = skeleton.parseAccounts(lookupTable);
Instruction[] instructions = skeleton.parseInstructions(accounts);
Transaction transaction = skeleton.createTransaction(instructions, lookupTable);

Creating Transactions
