Solana Connection

Learn how to create and manage Solana connections with the Dynamic Swift SDK.

Overview

The Solana connection allows you to interact with the Solana blockchain, query data, and prepare transactions.

Prerequisites

• Dynamic SDK initialized (see Quickstart)
• User authenticated (see Authentication)
• Solana wallets enabled in your Dynamic developer console

Create Connection

import DynamicSDKSwift

let sdk = DynamicSDK.instance()

func createConnection() throws {
    let connection = try sdk.solana.createConnection()
    print("Solana connection created")
}

Get Latest Blockhash

Required for building transactions:

import DynamicSDKSwift

let sdk = DynamicSDK.instance()

func getBlockhash() async throws -> String {
    let connection = try sdk.solana.createConnection()
    let result = try await connection.getLatestBlockhash()
    print("Latest blockhash: \(result.blockhash)")
    return result.blockhash
}

Query Account Balance

import DynamicSDKSwift
import SolanaWeb3

let sdk = DynamicSDK.instance()

func getBalance(address: String) async throws -> UInt64 {
    let connection = try sdk.solana.createConnection()

    guard let pubkey = try? PublicKey(string: address) else {
        throw SolanaError.invalidAddress
    }

    let balance = try await connection.getBalance(publicKey: pubkey)
    return balance
}

enum SolanaError: LocalizedError {
    case invalidAddress

    var errorDescription: String? {
        "Invalid Solana address"
    }
}

Get Solana Wallets

import DynamicSDKSwift

let sdk = DynamicSDK.instance()

let solanaWallets = sdk.wallets.userWallets.filter {
    $0.chain.uppercased() == "SOL"
}

for wallet in solanaWallets {
    print("Address: \(wallet.address)")
}

Solana Networks

Access configured Solana networks:

let sdk = DynamicSDK.instance()

let solanaNetworks = sdk.networks.solana

for network in solanaNetworks {
    print("Network: \(network.name)")
}

Connection Methods

Method	Description
createConnection()	Create a Solana connection instance
getLatestBlockhash()	Get the latest blockhash for transactions
getBalance(publicKey:)	Get account balance in lamports
getAccountInfo(publicKey:)	Get detailed account information

Dependencies

To build Solana transactions, add the SolanaWeb3 package:

// Package.swift
dependencies: [
    .package(url: "https://github.com/solana-mobile/SolanaSwift", from: "1.0.0")
]

• Sign Solana Messages - Sign messages
• Token Balances - Get SOL balance
