Building DeFi products is more than just deploying smart contracts. Developers need fast and reliable data to track protocol events, monitor asset flows, and trigger time-sensitive actions. Whether you’re building a lending protocol, a staking app, or a derivatives platform, access to real-time on-chain data is critical to user safety, contract logic, and UX quality.

​
What DeFi Builders Need

Real-time monitoring

Monitoring wallet and pool activity in real time

Low-latency tracking

Tracking token inflows/outflows at millisecond latency

Asset visibility

Getting up-to-date views of user assets, staked positions, and rewards

Event detection

Detecting on-chain triggers like liquidations, vault breaches, or oracle updates

​
How ChainStream Helps

ChainStream delivers the low-latency data layer DeFi protocols need to operate with confidence—even under network stress or market spikes.

Real-time event push

No more polling for state changes. Use event streams to react to deposits, swaps, claims, and oracle updates as they happen.

Account-level asset snapshots

Know exactly what a wallet holds—across chains, tokens, pools, and protocols—in a single API call.

Kafka-powered performance

Handle large event volumes with consistent throughput and low lag, even during volatile periods.

GraphQL for smart queries

Ask complex questions about pool status, address history, or token composition without chaining requests.

Core APIs for DeFi

​
Typical Scenarios

Lending & Borrowing Protocols

Monitor vault health, trigger liquidations, and update interest rates based on live market and user behavior data.

Staking & Yield Apps

Show real-time APY calculations, track staked token flows, and notify users of claimable rewards or pool changes.

Derivatives Platforms

React to market movement and user margin changes instantly. Use real-time balance and oracle data to protect traders from slippage or under-collateralization.

Risk Engines

Flag suspicious activity, detect abnormal TVL shifts, and throttle interactions when asset volatility spikes.

Reward Automation

Automatically distribute rewards, trigger incentive resets, or rebalance pools based on real-time user actions and protocol metrics.

​
Results Developers Can Expect

Millisecond-level response

Improve user safety and trust by eliminating lag in contract reactions.

Fewer systems to maintain

Skip writing indexers or syncing full nodes just to track events or balances.

Cross-chain DeFi logic

Get full asset and event coverage across Ethereum, Solana, Arbitrum, BNB Chain, and more—out of the box.

Confident contract triggers

Respond to actual on-chain data, not delayed snapshots or incomplete indexes.
