The short answer

Wallet tracking looks like one feature and is really four:

Current balances — what this address holds now, across chains.
Valuation — what it is worth, which requires prices for every token including the illiquid ones.
History — every transaction, transfer and swap, ideally categorised.
Real-time updates — pushing changes rather than polling.

Providers optimise for different subsets. Covalent and Moralis make one and three quick. Zerion is portfolio-native. Bitquery covers all four across more chains with streaming and point-in-time history, but you assemble the product yourself.

What to look for in a wallet tracking API

Chain coverage that matches your users. EVM-only breaks the moment someone connects a Solana or Bitcoin address.
Valuation of long-tail tokens. A portfolio full of "unknown token" is a broken product. Prices must come from DEX liquidity for tokens no CEX lists.
Historical point-in-time balances. "What did this wallet hold on 1 January" is a different query from "what does it hold now", and much harder for providers that only snapshot the present.
Spam filtering. Airdropped scam tokens dominate raw balance lists. Someone must filter them — the provider or you.
Push updates. Polling every wallet on every block does not scale.

The best wallet tracking APIs

1. Bitquery — best for multi-chain depth and real-time updates

Bitquery serves balances, transfers, DEX trades and token holdings across 40+ chains in one decoded schema — EVM chains alongside Solana, Bitcoin, Tron, XRP and Cardano. Because it indexes DEX liquidity, it can value long-tail tokens that never reach a centralized exchange, and because it keeps history, it answers point-in-time balance questions rather than only current state.

Updates can be streamed over WebSocket, Kafka with offset replay, or Solana gRPC, so a wallet screen updates on activity instead of on a timer.

Best for: multi-chain portfolio products, tax and accounting tools, wallet analytics, anything needing historical balances or non-EVM coverage.

Limitations: no RPC and no transaction submission. There is no single "get portfolio" endpoint — you compose the view from balances, prices and history; the wallet portfolio recipe in the docs shows the composition.

2. Covalent (GoldRush) — best for breadth with minimal integration

Covalent normalises balances, transactions and NFT holdings across a very large number of chains behind one REST shape.

Best for: shipping a multi-chain wallet view quickly.

Limitations: limited DEX depth, no streaming, and long-tail valuation is weaker.

3. Moralis — best REST endpoints and SDKs

Moralis offers purpose-built wallet, token and NFT endpoints with typed SDKs and a gentle learning curve.

Best for: standard wallet lookups where time to first call matters most.

Limitations: fixed endpoints; custom aggregations mean waiting for an endpoint or assembling client-side.

4. Zerion API — best portfolio-native model

Zerion built a wallet product first and exposes that model — positions, DeFi protocol holdings and portfolio structure rather than raw balances.

Best for: DeFi position awareness and portfolio semantics out of the box.

Limitations: its model is its opinion; if yours differs you will be working against it.

5. Alchemy — best when you already use it for RPC

Alchemy's token and NFT APIs sit alongside its RPC, convenient if it is already in your stack.

Best for: teams consolidating vendors.

Limitations: EVM-centred, and DEX-derived valuation is not the focus.

6. Birdeye — best for Solana-first portfolios

Birdeye covers wallet portfolios with strong Solana depth and token security signals.

Best for: Solana-first wallet products.

Limitations: ten chains.

FAQ

What is the best API for multi-chain wallet balances?

Covalent and Moralis are quickest to integrate for EVM breadth. Bitquery covers more non-EVM chains — Bitcoin, Tron, XRP, Cardano — in the same schema, with historical balances and streaming, at the cost of assembling the portfolio view yourself.

How do I value tokens with no exchange listing?

Price them from DEX liquidity. Bitquery computes prices from indexed on-chain trades across 300+ DEXs, which covers tokens that never list on a centralized exchange — usually the bulk of a retail wallet's long tail.

Can I get a wallet's balance at a past date?

Yes, with a provider that retains history. Bitquery answers point-in-time balance queries, which is what tax, accounting and performance reporting require. Providers that snapshot only current state cannot answer this at all.

How do I filter spam and scam tokens from a portfolio?

Combine holder distribution, trade history and liquidity checks — a token with no real trading and thousands of airdropped recipients is spam. Some providers filter for you; with raw data you set your own threshold, which matters because the line is a product decision.

Can I get real-time wallet updates?

Yes. Subscribe to transfers and trades filtered to your addresses over WebSocket or Kafka rather than polling. Polling every tracked wallet every block stops scaling quickly.
