Event-Driven Architecture
React to contract events, new blocks, and pending transactions with simple Python decorators.
Silverback
Silverback is a way to create Python bots to act and react to on-chain events.
What is Silverback?
Silverback is a framework for building event-driven Python bots that listen and react to blockchain activity. Built on top of the Ape ecosystem, it gives you the full power of Python to automate on-chain workflows.
Core Capabilities
Everything you need to build intelligent on-chain bots.
Built on Ape
Leverage the full Ape plugin ecosystem for multi-chain support, account management, and contract interaction.
Production Ready
Deploy bots that run reliably with built-in error handling, retries, and monitoring hooks.
Multi-Chain Support
Run bots against any network supported by Ape, from local forks to production Ethereum environments.
Python-Native
Write bots in clean, idiomatic Python. Use any library from the Python ecosystem alongside your bot logic.
Operational Workflows
Package repeatable on-chain operations into bots that can be tested locally and deployed with confidence.
How It Works
Define handlers, subscribe to events, deploy your bot.
1. Define Your Bot
bot.py
from silverback import SilverbackBot
bot = SilverbackBot()2. Handle Events
bot.py
@bot.on_(contract.Transfer)
def handle_transfer(log):
print(f"Transfer: {log.amount}")3. Run It
Terminal
silverback run --network ethereum:mainnetUse Cases
Silverback powers a wide range of on-chain automation.
DeFi Monitoring
Track liquidity changes, large swaps, and protocol health metrics in real-time.
Alerting & Notifications
Send alerts to Slack, webhooks, or email when specific on-chain conditions are met.
Data Pipelines
Stream decoded on-chain data into databases, dashboards, or analytics platforms.
Keeper Bots
Automate recurring protocol maintenance, liquidations, rebalances, and other time-sensitive actions.
Automated Actions
Execute transactions automatically in response to on-chain events and conditions.
Protocol Operations
Coordinate admin workflows, treasury movements, and safety checks with auditable Python logic.
