How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
Returns a paginated array of Optimism deposit records, each containing the L1 block number, L1 timestamp, L1 transaction hash, corresponding L2 transaction hash, the origin address of the L1 transaction, and the L2 gas limit. Also includes next_page_params for cursor-based pagination through additional results.
Example use cases
Trace a specific L1 deposit to L2
“I sent a deposit from Ethereum mainnet and want to confirm it landed on Optimism — can you look up the L1 transaction hash 0xabc123... in the Optimism deposits list on Blockscout for chain ID 10?”
Audit recent bridge deposit activity
“Pull me the last 50 Optimism deposit transactions from L1 block 19600000 onward on chain ID 10 so I can audit what was bridged recently.”
Monitor L2 gas limits on incoming deposits
“I need to review the L2 transaction gas limits for Optimism deposits coming in around L1 block 19450000 — can you fetch those records from Blockscout for chain ID 10?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/optimism/depositsWhen to prefer
Use this endpoint when you need structured, paginated data about Optimism L1-to-L2 bridge deposit transactions — especially when you want to correlate L1 transaction hashes with their L2 counterparts, audit bridge activity at a specific L1 block, or trace deposit origins. Prefer this over generic block explorers when you need machine-readable JSON output for Optimism deposits specifically.
