How this service works
Native ETH and ERC-20 token balances for a Base address in one call, read live from chain at a stated block height.
Output
Returns a structured response containing the native ETH balance and a list of ERC-20 token balances held by the specified Base address, read live from the blockchain at a stated block height. Each entry typically includes token symbol, contract address, and balance with decimals applied.
Example use cases
DeFi portfolio snapshot for user
“Can you check all the token balances — ETH and any ERC-20s — for my Base wallet 0xAbCd1234... and show me what I'm currently holding on chain?”
Pre-payment balance verification
“Before I send that USDC transfer, check whether the sender address 0x9f8e7d6c... actually has enough ETH and USDC on Base right now to cover it.”
Monitoring a whale wallet
“Look up the full on-chain portfolio of Base address 0xDeFi5678... — I want to see all their native ETH and ERC-20 token holdings as of the latest block.”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/data/portfolio/:addrWhen to prefer
Choose this endpoint when you need a combined snapshot of both native ETH and ERC-20 balances for a Base address in a single API call, avoiding the need to make separate requests per token. Ideal for portfolio views, pre-transfer checks, and agent workflows that need to reason about a wallet's full holdings on Base at a specific block.
Side effects
- Invalid or malformed Base address returns an error or empty result
- Address with no token holdings returns zero balances
- Network or RPC unavailability may cause timeout or 503
- Querying at a very old block height may not be supported
- Rate limiting if called excessively beyond the per-call pricing model
