Integrating with the SynX Network: Developer Deployment Guide

📅 Last updated: February 24, 2026 🎧 Listen: ~4 min

Ready to deploy your quantum-resistant application to the SynX network? This guide covers everything from testnet connection to mainnet deployment. The SynX quantum-resistant wallet serves as the reference implementation for network integration patterns.

Network Overview

SynX operates multiple networks for different purposes:

🧪 Testnet (Development)

Free test tokens, unstable block times, may reset periodically.

testnet.synxcrypto.com:8545

Chain ID: 7777 | Block Time: ~5s | Faucet: faucet.synxcrypto.com

🔒 Mainnet (Production)

Real value transactions, stable operation, high availability.

mainnet.synxcrypto.com:8545

Chain ID: 777 | Block Time: ~60s | TX Finality: Sub-second | Explorer: explorer.synxcrypto.com

🏠 Local Development

Run your own node for complete control and privacy.

localhost:8545

Configurable | Instant Mining Mode Available

Python SDK Setup

# Install SynX SDK
pip install synx-sdk

# Or from source
git clone https://github.com/synxcrypto/synx-sdk-python
cd synx-sdk-python
pip install -e .
            

Basic Connection

from synx import SynXClient, Network

# Connect to testnet
client = SynXClient(network=Network.TESTNET)

# Or mainnet
client = SynXClient(network=Network.MAINNET)

# Or custom node
client = SynXClient(
    rpc_url="http://localhost:8545",
    chain_id=7777
)

# Check connection
info = client.get_network_info()
print(f"Connected to: {info['network_name']}")
print(f"Block height: {info['block_height']}")
print(f"Peers: {info['peer_count']}")
            

RPC API Reference

SynX uses JSON-RPC 2.0 for all API calls. The API is compatible with standard patterns while supporting quantum-safe cryptography.

    def __init__(self, ws_url: str = "wss://mainnet.synxcrypto.com/ws"):

        address: str,
        callback
    ):
        """

        Notified on incoming/outgoing transactions.

        await self.ws.subscribe(
            method="address",
            params={"address": address},
            callback=callback
        )
    
    async def subscribe_to_blocks(self, callback):
        """Subscribe to new block events"""
        await self.ws.subscribe(
            method="newBlock",
            params={},
            callback=callback
        )
    
    async def subscribe_to_pending_txs(self, callback):
        """Subscribe to pending transaction pool"""

            method="pendingTransactions",
            params={},
            callback=callback
        )

# Example: Monitor wallet for incoming payments
async def main():
    monitor = RealtimeMonitor()
    
    async def on_activity(event):
        if event['type'] == 'incoming':
            print(f"Received {event['amount']} from {event['from']}")
        elif event['type'] == 'outgoing':
            print(f"Sent {event['amount']} to {event['to']}")
    
    await monitor.subscribe_to_address(

Running Your Own Node

For production applications, running your own node provides reliability and privacy:

# Install SynX node
git clone https://github.com/synxcrypto/synx-node
cd synx-node

# Build
cargo build --release

# Initialize for mainnet
./target/release/synx-node init --network mainnet

# Or testnet
./target/release/synx-node init --network testnet

# Start node
./target/release/synx-node run
            

Node Configuration

# config.toml
[network]
chain_id = 777
listen_addr = "0.0.0.0:30303"
max_peers = 50
bootstrap_nodes = [
    "/dns4/boot1.synxcrypto.com/tcp/30303/p2p/QmXyz...",
    "/dns4/boot2.synxcrypto.com/tcp/30303/p2p/QmAbc..."
]

[rpc]
enabled = true
listen_addr = "127.0.0.1:8545"
max_connections = 100
rate_limit = 1000  # requests per minute

[websocket]
enabled = true
listen_addr = "127.0.0.1:8546"

[storage]
data_dir = "/var/synx/data"
cache_size_mb = 2048

[mining]
enabled = false  # Set to true for validator nodes
coinbase = "synx1youraddress..."

[logging]
level = "info"
file = "/var/log/synx/node.log"
            

Mainnet Deployment Checklist

Test on Testnet
Fully test all functionality with test tokens. The SynX quantum-resistant wallet reference implementation includes a testnet mode for development.
Security Audit
Complete the security audit checklist. Verify all cryptographic operations use SPHINCS+ signatures correctly.
Load Testing
Simulate production load. Test signature generation performance under concurrent requests.
Error Handling
Implement retry logic for network failures. Handle all RPC error codes appropriately.
Monitoring Setup
Configure alerting for node health, transaction failures, and signature issues.
Backup Procedures
Ensure key backup and recovery procedures are tested. Never lose access to signing keys.
Gradual Rollout
Start with small transaction amounts. Increase limits as confidence builds.

Error Handling

Error Code	Description	Action
-32000	Insufficient balance	Check balance before sending
-32001	Invalid nonce	Fetch fresh nonce from node
-32002	Invalid signature	Verify signing key matches sender
-32003	Transaction expired	Rebuild with current timestamp
-32004	Duplicate transaction	Already processed, safe to ignore
-32005	Fee too low	Increase fee and resubmit

Frequently Asked Questions

What are the SynX network endpoints?

SynX provides testnet (testnet.synxcrypto.com:8545), mainnet (mainnet.synxcrypto.com:8545), and public RPC nodes. For production applications, running your own node is recommended for reliability and privacy. The SynX quantum-resistant wallet connects to dedicated infrastructure nodes.

How do I submit transactions to the SynX network?

Create a transaction with quantum-safe signatures (SPHINCS+), serialize it according to the SynX transaction format, and submit via the synx_sendTransaction RPC method. The network validates both the signature and transaction structure before inclusion in a block.

Before Mainnet

Always test thoroughly on testnet first. Mainnet transactions involve real value and cannot be reversed.
