Example use cases
DeFi dashboard token enrichment
“Can you look up the token metadata for the zkSync contract at 0x3355df6D4c9C3035724Fd0e3914dE96A5a83aaf6? I need the name, symbol, and decimals to display it properly in my dashboard.”
Verify unknown token contract
“I see an unfamiliar token contract on zkSync — address 0x000000000000000000000000000000000000800A — can you tell me what token this actually is?”
Portfolio tracker token resolution
“I'm building a portfolio tracker and need to resolve token details for a few zkSync contracts. Start with 0x5AEa5775959fBC2557Cc8789bC1bf90A239D9a91 — what's the name and symbol?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/zksync/token/metadataWhen to prefer
Choose this endpoint when you specifically need token metadata from the zkSync (zkSync Era / ZK Stack) Layer 2 network, rather than Ethereum mainnet or other L2s. Ideal for DeFi apps, portfolio trackers, block explorers, and wallet UIs that need to display human-readable token information for zkSync-native or bridged tokens.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (e.g. a generic smart contract) may return empty or error
- Non-existent address on zkSync returns not-found error
- Network or RPC unavailability causes timeout
- Rate limiting or payment failure blocks the request
