#5	## Solana Transactions
#6
#7	### Dependencies
#8
#9	```bash
#10	npm install @solana/web3.js
#11	# OR for newer @solana/kit
#12	npm install @solana/kit
#13	```
#14
#15	### SOL Transfer with @solana/web3.js
#16
#17	```ts
#18	import {
#19	Connection,
#20	PublicKey,
#21	SystemProgram,
#22	VersionedTransaction,
#23	TransactionMessage,
#24	} from "@solana/web3.js";
#25
#26	async function transferSol(solana, recipient: string, lamports: number) {
#27	const connection = new Connection("https://api.mainnet-beta.solana.com");
#28	const { blockhash } = await connection.getLatestBlockhash();
#29
#30	const fromAddress = await solana.getPublicKey();
#31
#32	const message = new TransactionMessage({
#33	payerKey: new PublicKey(fromAddress),
#34	recentBlockhash: blockhash,
#35	instructions: [
#36	SystemProgram.transfer({
#37	fromPubkey: new PublicKey(fromAddress),
#38	toPubkey: new PublicKey(recipient),
#39	lamports,
#40	}),
#41	],
#42	}).compileToV0Message();
#43
#44	const transaction = new VersionedTransaction(message);
#45	const result = await solana.signAndSendTransaction(transaction);
#46
#47	return result.hash;
#48	}
#49
#50	// Usage: 0.001 SOL = 1,000,000 lamports
#51	const txHash = await transferSol(solana, "recipient-address", 1000000);
#52	```
#53
#54	### SOL Transfer with @solana/kit
#55
#56	```ts
#57	import {
#58	createSolanaRpc,
#59	pipe,
#60	createTransactionMessage,
#61	setTransactionMessageFeePayer,
#62	setTransactionMessageLifetimeUsingBlockhash,
#63	address,
#64	compileTransaction,
#65	} from "@solana/kit";
#66
#67	async function transferSolKit(solana, recipient: string) {
#68	const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");
#69	const { value: latestBlockhash } = await rpc.getLatestBlockhash().send();
#70
#71	const userPublicKey = await solana.getPublicKey();
#72
#73	const transactionMessage = pipe(
#74	createTransactionMessage({ version: 0 }),
#75	(tx) => setTransactionMessageFeePayer(address(userPublicKey), tx),
#76	(tx) => setTransactionMessageLifetimeUsingBlockhash(latestBlockhash, tx)
#77	);
#78
#79	const transaction = compileTransaction(transactionMessage);
#80	const result = await solana.signAndSendTransaction(transaction);
#81
#82	return result.hash;
#83	}
#84	```
#85
#86	### SPL Token Transfer
#87
#88	```ts
#89	import {
#90	Connection,
#91	PublicKey,
#92	VersionedTransaction,
#93	TransactionMessage,
#94	} from "@solana/web3.js";
#95	import {
#96	getAssociatedTokenAddress,
#97	createTransferInstruction,
#98	} from "@solana/spl-token";
#99
#100	async function transferToken(
#101	solana,
#102	mint: string,
#103	recipient: string,
#104	amount: number,
#105	decimals: number
#106	) {
#107	const connection = new Connection("https://api.mainnet-beta.solana.com");
#108	const { blockhash } = await connection.getLatestBlockhash();
#109
#110	const fromAddress = await solana.getPublicKey();
#111	const fromPubkey = new PublicKey(fromAddress);
#112	const mintPubkey = new PublicKey(mint);
#113	const toPubkey = new PublicKey(recipient);
#114
#115	const fromAta = await getAssociatedTokenAddress(mintPubkey, fromPubkey);
#116	const toAta = await getAssociatedTokenAddress(mintPubkey, toPubkey);
#117
#118	const transferAmount = amount * Math.pow(10, decimals);
#119
#120	const message = new TransactionMessage({
#121	payerKey: fromPubkey,
#122	recentBlockhash: blockhash,
#123	instructions: [
#124	createTransferInstruction(fromAta, toAta, fromPubkey, transferAmount),
#125	],
#126	}).compileToV0Message();
#127
#128	const transaction = new VersionedTransaction(message);
#129	return await solana.signAndSendTransaction(transaction);
#130	}
#131	```
#132
#133	### Sign Without Sending
#134
#135	```ts
#136	// Sign only (for offline signing, multi-sig, etc.)
#137	const signedTx = await solana.signTransaction(transaction);
#138
#139	// Then send later
#140	const connection = new Connection("https://api.mainnet-beta.solana.com");
#141	const signature = await connection.sendRawTransaction(signedTx.serialize());
#142	```
#143
#144	### Network Switching
#145
#146	```ts
#147	// Switch networks before transactions
#148	await solana.switchNetwork("devnet");
#149	// Options: "mainnet-beta", "devnet", "testnet"
#150	```
#151
#152	## Message Signing
#153
#154	```ts
#155	// Sign a message
#156	const message = "Hello World";
#157	const { signature } = await solana.signMessage(message);
#158	console.log("Signature:", signature);
#159	```
#160
#161	## Error Handling
#162
#163	```ts
#164	try {
#165	const result = await solana.signAndSendTransaction(transaction);
#166	console.log("Success:", result.hash);
#167	} catch (error) {
#168	if (error.message.includes("User rejected")) {
#169	console.log("User cancelled the transaction");
#170	} else if (error.message.includes("insufficient funds")) {
#171	console.log("Not enough balance");
#172	} else {
#173	console.error("Transaction failed:", error);
#174	}
#175	}
#176	```
#177
#178	## Transaction Status Checking
#179
#180	```ts
#181	import { Connection } from "@solana/web3.js";
#182
#183	const connection = new Connection("https://api.mainnet-beta.solana.com");
#184
#185	// Wait for confirmation
#186	const confirmation = await connection.confirmTransaction(signature, "confirmed");
#187
#188	// Get transaction details
#189	const txDetails = await connection.getTransaction(signature);
#190	```
#191
#192	## Fee Estimation
#193
#194	```ts
#195	import { Connection } from "@solana/web3.js";
#196
#197	const connection = new Connection("https://api.mainnet-beta.solana.com");
#198
#199	// Get recent prioritization fees
#200	const fees = await connection.getRecentPrioritizationFees();
#201
#202	// Get minimum balance for rent exemption
#203	const minBalance = await connection.getMinimumBalanceForRentExemption(dataSize);
#204	```
