How this service works
Portfolio of a wallet on Base: native ETH plus a curated set of major ERC-20s (USDC, WETH, cbETH, cbBTC, DAI, USDbC), each valued in USD on-chain via Uniswap v3. Returns per-token amounts, USD values and the total.
Output
Returns a structured breakdown of the wallet's holdings on Base: native ETH plus up to six major ERC-20 tokens (USDC, WETH, cbETH, cbBTC, DAI, USDbC), each with its token amount and current USD value priced on-chain via Uniswap v3. Also includes a single total portfolio USD value aggregating all positions.
Example use cases
DeFi wallet net worth check
“Can you tell me the total USD value of everything held in 0x4f8a3b...c910 on Base, broken down by token including ETH, USDC, and any other major holdings?”
Pre-trade liquidity assessment
“Before I make a large trade, check what tokens and USD balances are sitting in 0xDeF7...2201 on Base so I know what's available to work with.”
Monitoring a watched wallet
“What's the current portfolio breakdown for wallet 0x9aB1...F443 on Base? I want to see each token, how much of it there is, and what it's worth in dollars right now.”

Endpoint
POSThttps://auditor-x402.onrender.com/api/wallet-portfolio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, multi-token USD-denominated snapshot of a Base wallet's holdings across ETH and the most liquid DeFi assets (USDC, WETH, cbETH, cbBTC, DAI, USDbC) with on-chain pricing from Uniswap v3. Prefer this over block explorer APIs when you want live USD values rather than raw balances, and over full portfolio aggregators when you only care about Base mainnet and major tokens without off-chain price feeds.
Side effects
- Invalid or malformed wallet address returns an error
- Wallet with zero balances returns all zeros without error
- Uniswap v3 on-chain pricing unavailable for a token may result in missing USD value
- Network congestion on Base may cause slow or failed RPC responses
- Cold start latency on Render.com free tier may cause initial timeout
- Only a fixed curated set of tokens is supported; non-listed ERC-20s are not included
