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 the native ETH balance plus all ERC-20 token balances held by the specified Base address, read live from the blockchain at a stated block height. Includes token symbols, amounts with decimals applied, and the block at which the snapshot was taken.
Example use cases
Pre-payment wallet verification
“Before I send USDC to 0xAbCd...1234, can you pull their live Base portfolio so I can see what tokens they hold and confirm the address looks active?”
DeFi portfolio snapshot for reporting
“Give me a full snapshot of all ETH and ERC-20 balances on Base for 0xDeFi...5678 right now — I need the complete holdings for my portfolio report.”
Agent treasury monitoring
“Check the current on-chain ETH and token balances for our treasury wallet 0xTrea...9999 on Base so I know what funds are available to deploy.”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/data/portfolio/%3Aaddr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-call, live on-chain portfolio view combining both native ETH and all ERC-20 token balances for a Base address. Prefer it over separate per-token balance calls when you want a comprehensive holdings snapshot without multiple round trips. Ideal for pre-payment checks, treasury monitoring, or DeFi portfolio analysis on the Base network.
Side effects
- Invalid or malformed Base address returns a 4xx error
- Address with no holdings may return zero balances for all assets
- Unpaid request returns HTTP 402 with x402 payment requirements
- Network congestion or RPC issues may cause timeouts or stale reads
- Very new addresses not yet indexed may return empty results
