Overview

The Universal Wallets API brings multi-chain wallet data into a single, consistent request shape. Instead of querying one chain at a time and stitching responses together client-side, you ask for the chains you care about in one call and receive a unified response. The first endpoint in this group is Cross-Chain Token Balances - a multi-chain version of one of our most-used Deep Index endpoints.

​
What Is the Universal Wallets API?

The Universal Wallets API lets you query:
  • Cross-Chain Token Balances - Token balances for a wallet across multiple chains in one call
Wallet profitability also went multi-chain: see Wallet PnL and Wallet PnL Summary in the PnL API. More multi-chain wallet endpoints are on the way as we consolidate cross-chain functionality into the Universal API.

​
Key Features

  • Multi-chain in one call - Query a wallet across many chains in a single request
  • Same trusted filters - Spam exclusion, unverified contracts, liquidity thresholds, USD pricing - all carry over from the legacy Deep Index endpoints
  • Unified response shape - One schema across chains, no client-side stitching
  • Direct migration path - Existing implementations port cleanly with minimal changes

​
Common Use Cases

  • Wallets - Show full multi-chain holdings on a single screen
  • Exchanges - Surface a user’s deposit balances across networks
  • Portfolio Trackers - Aggregate token holdings across EVM and Bitcoin in one query, with Solana available today through its dedicated Wallet API
  • Tax Tools - Pull a complete asset list per wallet for cost-basis and reporting flows
  • AI Agents - Hand the model a single response containing the wallet’s full token footprint

​
Roadmap

Cross-Chain Token Balances currently covers EVM chains and Bitcoin (address or xpub) in the same multi-chain request. Solana already has full standalone coverage through its dedicated API: Next on this endpoint: bringing Solana into the same multi-chain request shape, so one call returns balances across EVM, Bitcoin, and Solana wallets.
