# Stellar Blockchain
### Stellar Blockchain Integration
K3 Labs now fully supports the **Stellar blockchain**, including **Soroban smart contracts**, across both **mainnet and testnet**, enabling users to build advanced no-code automations using real-time events, smart contracts, and wallet interactions.
***
### Supported Functions
K3 supports Stellar across four major function types: **Triggers**, **Read**, **Write**, and **Wallet Integration**.
***
## โก Triggers
### **1. Smart Contract Events**
Monitor **on-chain events** emitted by Soroban smart contracts.
* Blockchain: Stellar Mainnet or Testnet
* Contract to try:\
`CAS3FL6TLZKDGGISSDBWGGPTX3NRR4DYTZD7Y0D3HMY06LTJUVGVREAM`
* Example event types supported:\
`mint`, `transfer`, `burn`, `approve`, `set_admin`
* Steps:
1. Select "Trigger: Smart Contract"
2. Choose Stellar Mainnet
3. Paste the contract address above
4. Choose the event type you wish to monitor
**Example Use Case:**\
Monitor a token for `mint` events and send an alert whenever new tokens are issued.
***
### **2. Wallet Events**
Track **all on-chain activity** related to a Stellar wallet.
* Blockchain: Stellar Mainnet or Testnet
* Example Wallet:\
`GBKUE3CEBSN5TJWQIJIJDUSRYEJGICSTE62KQIB24KLIU42GWGB32VNT`
* Steps:
1. Select "Trigger: Wallet Events"
2. Choose Stellar Mainnet
3. Enter the wallet address above
4. Choose either:
* All activity
* Sent
* Received
You can retrieve:
* `from` / `to` wallet address
* `token` transferred
* `amount`
* `transaction hash`
**Example Use Case:**\
Detect incoming airdrops or payments, and trigger Telegram/email notifications.
***
## ๐ Read Functions
### **3. Read Smart Contract**
Fetch method outputs directly from Soroban contracts.
* Blockchain: Stellar Mainnet
* Contract to try:\
`CAS3FL6TLZKDGGISSDBWGGPTX3NRR4DYTZD7Y0D3HMY06LTJUVGVREAM`
* Supported methods: `balance`, `allowance`
* Steps:
1. Select "Read: Smart Contract"
2. Choose Stellar
3. Add the contract address above
4. Select method and input required params
**Use Case:**\
Pull on-chain balances from a lending or token contract.
***
### **4. Read Wallet Balance**
Check a walletโs portfolio and value.
* Wallet:\
`GBKUE3CEBSN5TJWQIJIJDUSRYEJGICSTE62KQIB24KLIU42GWGB32VNT`
* Steps:
1. Select "Read: Wallet Balance"
2. Choose Stellar Mainnet
3. Paste wallet address
Returns:
* Total USD value of wallet
* List of token holdings and balances
**Use Case:**\
Track real-time portfolio distribution and trigger alerts if rebalancing is needed.
***
## ๐ Write Functions
### **5. Write to Smart Contract**
Interact with Stellar smart contracts (Soroban) via workflow.
* Blockchain: Stellar Mainnet
* Contract: **Fixed XLM-USDC**\
`CDVQVKOY2YSXS2IC7KN6MNASSHPAO7UN2UR2ON4OI2SKMFJNVAMDX6DP`
* Supported methods:
* `set_reserve`
* `get_positions`
* `submit`
* `claim`
* `new_liquidation_auction`
* `new_interest_auction`
* and more
Steps:
1. Choose โWrite to Smart Contractโ
2. Select Stellar Mainnet
3. Add contract address
4. Pick method (e.g. `submit` or `claim`)
5. Add parameters if required
**Use Case:**\
Automate interactions with Blend Capital contracts to submit, claim, or participate in auctions.
***
### **6. Stellar Wallet via Cubist**
Use **Cubist** to create secure wallets for Stellar. These wallets are used to **sign and pay for gas** for any on-chain interactions (writes).
* Create wallet in the **Cubist integration panel**
* Once created, itโs available for use in Write to Smart Contract
Cubist benefits:
* Hardware-backed key security
* Seamless gas management
* No external signing or extensions needed
***
### 7. Token Transfers
Users can dend tokens from a Stellar wallet to another address as part of your workflow.
* **Blockchain:** Stellar Mainnet
* **Wallet:** Use a Stellar wallet created via the **Cubist** integration
* **Function:** Token Transfer
**Steps:**
1. Add the **Token Transfer** function to your workflow
2. Choose Stellar as the blockchain
3. Select your Stellar wallet (Cubist-based)
4. Input:
* Recipient wallet address
* Token address or ticker (e.g. `XLM`)
* Amount to transfer
**Use Cases:**
* Recurring payments (e.g. team salary disbursements)
* Conditional transfers based on workflow logic (e.g. only if balance > X)
* Treasury management or payment batching
You can easily combine this with:
* **Time-based triggers** (e.g. monthly)
* **Smart contract reads** (e.g. check positions before payout)
* **Conditional logic** (e.g. ensure wallet has minimum balance)
***
### Stellar Sample Workflows
#### ๐ Airdrop Detection
Trigger on wallet โ If token is `XYZ` โ Notify user via Telegram.
#### ๐ Portfolio Check
Run every hour โ Read wallet โ Transform into % shares โ Alert on deviation.
#### ๐ง Lending Protocol Automation
Trigger on Blend contract โ Write: `claim` or `submit` โ Notify if complete.
***
### Why Use Stellar on K3?
* Real-time automations using Soroban smart contracts
* Support for event-based or time-based triggers
* Simplified UI for complex contract reads/writes
* No need to manage your own keys โ Cubist handles it
* Monitor wallets, trigger actions, and publish data โ all no-code
* Secure wallet management with Cubist
