How this service works
Recent event logs of a Base network contract (up to 1,000 blocks back, 200 events), with token Transfer and Approval events decoded (from, to, amount).
Output
Returns a JSON object containing a list of decoded events (each with event type, from address, to address, raw amount, transaction hash, and block number), plus the contract address and the block range scanned (from_block and to_block). Up to 200 events across up to 1,000 recent blocks.
Example use cases
Monitor recent token transfers
“Show me all Transfer events from the last 300 blocks for the Base ERC-20 contract at 0x4200000000000000000000000000000000000006 — I want to see the from address, to address, and amount for each one.”
Audit approval activity for a DeFi contract
“Get me the recent Approval events for the Base contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 going back 1000 blocks so I can see which wallets approved large spending allowances.”
Investigate on-chain token activity
“Can you fetch the latest on-chain events for Base contract 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb and decode any Transfer or Approval events so I can see what happened in the past few hundred blocks?”
Technical details
Endpoint
GEThttps://manylives.me/paid/chain/events?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need decoded ERC-20 Transfer and Approval event logs for a specific Base network contract without running your own node or indexer. It's ideal for lightweight on-chain monitoring, DeFi auditing, and token flow analysis on Base — especially when you want human-readable decoded fields (from, to, amount) rather than raw log data. Prefer this over general blockchain explorers when you need programmatic JSON output suitable for agent pipelines and can tolerate the 200-event and 1,000-block window limits.
Side effects
- Missing or invalid contract address returns an error (address is required)
- Requesting more than 1,000 blocks is capped at the maximum silently or returns an error
- No events found in the requested range returns an empty events array
- Invalid event type filter (not 'transfer', 'approval', or a valid 0x topic hash) may return no results or an error
- Contract with no Transfer/Approval events returns empty decoded results even if raw logs exist
- Network latency or Base RPC issues may cause timeouts
