getTokenAccountsByOwner

[wiyarmir]

TL;DR

Added support for retrieving SPL Token accounts by owner with optional mint or program ID filtering.

What changed?

• Created a new PublicKeyBase58Serializer for handling Base58 serialization of public keys
• Implemented getTokenAccountsByOwner methods with support for filtering by mint or program ID
• Added data classes to represent token account information including account details, token amounts, and ownership data

How to test?

// Test retrieving token accounts by owner and mint
val tokenAccounts = client.getTokenAccountsByOwnerAndMint(
    account = ownerPublicKey,
    mint = mintPublicKey
)

// Test retrieving token accounts by owner and program ID
val programTokenAccounts = client.getTokenAccountsByOwnerAndProgramId(
    account = ownerPublicKey,
    programId = programPublicKey
)

Why make this change?

This addition enables querying and filtering SPL Token accounts, which is essential for applications that need to track token holdings, manage token accounts, or analyze token-related activities for specific accounts on the Solana blockchain.

Bug: Non-nullable uiAmount will fail on null API responses

The uiAmount field in TokenAmount is declared as non-nullable Double, but the Solana RPC API can return null for this deprecated field. The existing TokenAmountInfo class in getTokenAccountBalance.kt correctly uses Double? for this same field. When the API returns null for uiAmount, deserialization will fail with a runtime exception.
