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
An HTTP JSON response confirming the address submission was received by Blockscout's metadata extractors. The response body structure is minimal (schema example is empty {}), likely returning a success status or submission ID indicating the addresses have been queued for enrichment and indexing.
Example use cases
Index new contract after deployment
“I just deployed a new smart contract at 0x1234567890abcdef1234567890abcdef12345678 — can you submit it to Blockscout's metadata extractors so it shows up properly in their multichain explorer?”
Tag a DeFi protocol wallet
“Register our DeFi protocol's treasury wallet 0xdeadbeef... with Blockscout so it gets labeled and enriched with metadata across all the chains they support.”
Bulk onboard team addresses to explorer
“We have a list of multisig addresses used by our DAO — can you submit each one to Blockscout's address metadata system so they appear correctly tagged in the block explorer?”
Technical details
Endpoint
POSThttps://api.blockscout.com/services/metadata/api/v1/addresses:submit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to register, label, or enrich blockchain addresses in Blockscout's multichain index — particularly after deploying a new contract or onboarding addresses to make them discoverable in Blockscout's explorer. Prefer this over read/search endpoints when your goal is to write address metadata rather than query it.
