How this service works
ChainRay /contract-events
Output
A list of on-chain events emitted by or associated with the specified contract or wallet address on the given blockchain, including event names, transaction hashes, block numbers, timestamps, and decoded event parameters.
Example use cases
DeFi protocol activity monitoring
“Check what events the Uniswap V3 router contract has been emitting on Ethereum over the last week so I can track swap volumes and liquidity changes.”
Suspicious wallet transaction investigation
“Pull all the contract events associated with wallet 0x1234567890abcdef on Polygon to see what smart contracts it's been interacting with and what activities it triggered.”
Cross-chain token transfer audit
“Show me the complete event history for our staking contract across Ethereum, Arbitrum, and Optimism so we can reconcile all the stake and unstake events that occurred.”
Technical details
Endpoint
GEThttps://chainray.online/contract-events/:var1When to prefer
Use this endpoint when you need to retrieve the event log history for a specific smart contract or wallet address on a particular blockchain network. It is ideal for DeFi monitoring, auditing contract interactions, tracking token transfers or approvals, and understanding historical on-chain activity for a given address. Prefer this over generic block explorers when you need structured, agent-consumable event data across 46+ chains via a single API.
Side effects
- Invalid or malformed address returns a 400 error
- Unsupported or unrecognized chain identifier returns an error
- Address with no contract events returns an empty result set
- Payment failure or insufficient USDC balance returns a 402 error
- Rate limiting or quota exceeded returns a 429 error
- Network congestion on the target chain may cause stale or delayed data
