Multi-Chain Crypto Wallet API

Probably best crypto wallet API for 120+ blockchains: Cardano, Tron, Litecoin, Cosmos, and Layer 2 networks. One integration for all chains.

Probably best crypto wallet API for 120+ blockchains: Cardano, Tron, Litecoin, Cosmos, and Layer 2 networks. One integration for all chains.

Beyond Solana, Ethereum, and Bitcoin, CoinStats API supports dozens of additional blockchain networks. The same endpoint format works across all of them: pass a wallet address and a connection ID, and get balances, token holdings, and transaction history regardless of the underlying chain. No chain-specific integrations, no separate SDKs, no different response formats.

Building multi-chain wallet support from scratch means integrating a different data source for each blockchain: a Cardano node for ADA balances, a Tron API for TRC-20 tokens, a Cosmos LCD endpoint for staking data, and so on. Each chain has its own address format, transaction structure, and token standard. CoinStats API normalizes all of this into a single response format, which is why it fits most multi-chain use cases out of the box.

This page covers the non-EVM, non-Solana, non-Bitcoin chains. For chain-specific documentation, see Solana Wallet API, Ethereum & EVM Chains page, or Bitcoin Wallet Integration page. All wallet data is also accessible through CoinStats MCP Server for AI agents.

Why One API for All Chains

The typical approach to multi-chain wallet tracking looks like this: integrate the Cardano Blockfrost API for ADA, the TronGrid API for TRX, the Cosmos LCD for ATOM, and so on. Each integration has its own authentication, rate limits, response format, and error handling. Maintaining five chain integrations is manageable. Maintaining twenty is a full-time job.

CoinStats API replaces all of these with a single integration. The endpoint format is identical for every chain: /wallet/balance?address={address}&connectionId={chain}. The response is always an array of token objects with the same fields: coinId, amount, name, symbol, price, 24h change, rank, volume, and chain. Your application code handles Cardano the same way it handles Tron, Litecoin, or any other chain.

This is the same data infrastructure that powers the CoinStats app, used by over 1M people every month. The multi-chain wallet data has been battle-tested at scale.

We continuously add support for new chains. The blockchains endpoint always returns the current list, so you can dynamically build chain selectors in your UI.

Universal Wallet Tracking

Every supported chain uses the same endpoint format. Pass the wallet address and the chain’s connection ID:

Cardano

curl -H "X-API-KEY: your-api-key" \
  "https://openapiv1.coinstats.app/wallet/balance?address=addr1qxy2lpan99fcnf2du5et5gw9qz8w8ky8f8m4lnhfg2r6e9a4zhk3ey7m8f4n8k7e8d5u8m8h3g2f9b8z2y3r6v9x8s&connectionId=cardano"

The response format is identical across all chains: an array of token objects with amount, price, 24h change, market cap rank, and volume. This means your application code can handle any chain without chain-specific parsing logic. One function queries any wallet on any chain.

Chain-Specific Features

While the API provides a unified interface, some chains have unique capabilities worth noting:

Cardano (ADA)

Cardano wallets can include staking delegation, native token holdings (not just ADA), and pool rewards. The API captures all of these, so portfolio trackers can show staked ADA alongside freely available balances. Staking rewards are particularly important for tax tools, since they’re considered taxable income in many jurisdictions.

Balance

curl -H "X-API-KEY: your-api-key" \
  "https://openapiv1.coinstats.app/wallet/balance?address=addr1qxy2lpan99fcnf2du5et5gw9qz8w8ky8f8m4lnhfg2r6e9a4zhk3ey7m8f4n8k7e8d5u8m8h3g2f9b8z2y3r6v9x8s&connectionId=cardano"

Tron (TRX)

Tron wallets involve TRC-20 tokens (similar to ERC-20 on Ethereum), energy/bandwidth resource management, and DeFi protocol interactions (JustSwap, SUN.io). The API tracks all TRC-20 holdings and DeFi positions. Tron’s USDT volume makes it one of the most actively used chains for stablecoin transfers, so wallet tracking tools that support Tron cover a significant portion of global crypto activity.

curl -H "X-API-KEY: your-api-key" \
  "https://openapiv1.coinstats.app/wallet/balance?address=TLyqzVGLV1srkB7dToTAEqgDSfPtXRJZYH&connectionId=tron"

Litecoin (LTC)

Litecoin tracking works similarly to Bitcoin, supporting both single addresses and transaction history with mining reward detection. Litecoin is commonly held as a long-term asset, so portfolio trackers that include LTC alongside BTC and ETH cover the major “legacy” crypto holdings.

curl -H "X-API-KEY: your-api-key" \
  "https://openapiv1.coinstats.app/wallet/transactions?address=LQTpS7F9y5xPMxbNGqPjRzPz8k7hGa9Xqm&connectionId=litecoin"

Cosmos (ATOM)

Cosmos wallets involve IBC transfers between chains, staking with validators, and governance participation. The Cosmos ecosystem includes dozens of IBC-connected chains (Osmosis, Juno, Akash, etc.), and users frequently move tokens between them. The CoinStats API tracks balances and transactions on the Cosmos Hub, with the connection ID cosmos.

Credit Costs

Endpoint	Credits	Description
Wallet balance	40	All tokens for one address on one chain
Transaction history	30	Paginated transaction list
Transaction sync	50	Index latest transactions

The same credit costs apply across all chains. There’s no premium pricing for less common networks.

What You Can Build With Multi-Chain Wallet Data

Unified Portfolio Dashboards

Most crypto users hold assets across multiple chains. A single user might have ADA staked on Cardano, TRX on Tron, LTC as a long-term hold, DOGE from 2021, and tokens spread across several EVM chains. Building a portfolio dashboard that covers all of this normally requires integrating 5-10 different blockchain APIs, each with its own authentication, response format, and rate limits.

CoinStats API lets you query all of these through the same endpoint format, aggregate the results into a single portfolio value, and render per-chain breakdowns without writing chain-specific code. The response format is identical across all chains, so one component in your UI handles every network.

Cross-Chain Tax Reporting

Tax tools need transaction histories from every chain a user has touched. Since CoinStats API uses the same endpoint and response format for all chains, you can loop through a user’s wallet addresses and pull transaction data without maintaining separate integrations. Each transaction includes timestamps, amounts, and token identifiers for cost-basis calculations.

For chains like Cardano where staking rewards are common, the transaction history captures reward distributions as distinct transactions. This is important because staking rewards are typically taxed as income at the time of receipt, separate from any capital gains when the tokens are later sold.

Institutional Custody Monitoring

Organizations holding crypto across multiple blockchains need a single data source that covers all their chains. The CoinStats API provides this without requiring separate node infrastructure or chain-specific indexers for each network. One API key, one integration, every chain. This is particularly relevant for funds and custody providers that hold diversified crypto portfolios across Layer 1 chains.

Wallet Comparison and Analytics Tools

If you’re building analytics tools that compare wallet activity across chains, the uniform response format makes it straightforward. Query a Cardano address and a Tron address, and you get back the same data structure. This lets you build chain-agnostic analytics: total holdings by chain, per-chain allocation percentages, and cross-chain activity timelines.

AI-Powered Multi-Chain Assistants

Through CoinStats MCP Server, AI agents can query any supported blockchain using the same tool set. An AI assistant can check a Cardano wallet balance, look up Tron transactions, and aggregate holdings across chains, all through natural language queries. This works with Claude, Cursor, Claude Code, and other MCP-compatible tools.

The MCP Server is particularly useful for multi-chain queries because the AI agent can query several chains in sequence and aggregate the results, just like a developer would with the REST API. No per-chain configuration needed on the AI side.
