+# Mx.NET.SDK.SmartSend
+⚡ MultiversX SmartSend TypeScript SDK: Library for interacting with Smart Send contracts on MultiversX blockchain
+
+## How to install?
+The content is delivered via npm package:
+##### [@remarkabletools/mx-smartsend](https://www.npmjs.com/package/@remarkabletools/mx-smartsend)
+
+## Main Features
+- Create EGLD/Token/MetaESDT/NFT/SFT transactions for Smart Send contracts
+
+## Quick start guide
+### Basic example
+```javascript
+const provider = new ProxyNetworkProvider('https://devnet-gateway.multiversx.com')
+const networkConfig = await provider.getNetworkConfig()
+
+const myaddress = Address.fromBech32('MY_ADDRESS')
+const accountOnNetwork = await provider.getAccount(myaddress)
+const account = new Account(myaddress)
+account.update(accountOnNetwork)
+
+const smartSend = new SmartSend(account, networkConfig, 'MY_CONTRACT_BECH32_ADDRESS')
+
+const inputTransactions = []
+for (let i = 1; i < 10; i++) {
+  inputTransactions.push(new TokenAmount('RECEIVER_ADDRESS', TokenTransfer.egldFromAmount('0.0' + i))) // TokenTransfer can also be fungibleFromAmount / metaEsdtFromAmount / nonFungible / semiFungible
+}
+
+try {
+  const txs = smartSend.createEGLDTransactions(inputTransactions) // or createTokenTransactions / createMetaESDTTransactions / createNFTTransactions / createSFTTransactions
+  // sign and send egldTxs
+} catch (error) {
+  console.log(error)
+}
+```
+
+### Advanced example
+*The following example is using a wallet __signer__ that should not be used in production, only in private!*
+```javascript
+const provider = new ProxyNetworkProvider('https://devnet-gateway.multiversx.com')
+const networkConfig = await provider.getNetworkConfig()
+
+const myaddress = Address.fromBech32('MY_ADDRESS')
+const accountOnNetwork = await provider.getAccount(myaddress)
+const account = new Account(myaddress)
+account.update(accountOnNetwork)
+
+const pemText = await promises.readFile('/path/wallet.pem', { encoding: 'utf8' })
+const signer = UserSigner.fromPem(pemText)
+
+const smartSend = new SmartSend(account, networkConfig, 'MY_CONTRACT_BECH32_ADDRESS')
+
+const inputTransactions = []
+for (let i = 1; i < 10; i++) {
+  inputTransactions.push(new TokenAmount('RECEIVER_ADDRESS', TokenTransfer.fungibleFromAmount('TOKEN-123456', i, 18))) // TokenTransfer can also be fungibleFromAmount / metaEsdtFromAmount / nonFungible / semiFungible
+}
+
+try {
+  const tokenTxs = smartSend.createTokenTransactions(inputTransactions)
+  for (const tx of tokenTxs) {
+    const serializedTransaction = tx.serializeForSigning()
+    const transactionSignature = await signer.sign(serializedTransaction)
+    tx.applySignature(transactionSignature)
+  }
+
+  const response = await provider.sendTransactions(tokenTxs)
+  console.log(response)
+} catch (error) {
+  console.log(error)
+}
+```
