Query stablecoin holdings for individual wallets across 10+ blockchain networks with a single API call. Get comprehensive balance data for USDT, USDC, DAI, and more across multiple chains including Ethereum, Solana, Polygon, BSC, and Tron.

Unified Multi-Chain Access

Retrieve stablecoin holdings for individual wallets across Ethereum, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, Base, Tron, and more with one JSON-RPC 2.0 call. Eliminates the need to manage multiple RPC endpoints and chain-specific implementations for balance queries.

Comprehensive Stablecoin Coverage

Access balance data for USDT, USDC, USDC.e, DAI, BUSD, TUSD, FRAX, and other major stablecoins. Automatically handles ERC-20, SPL, TRC-20, and BEP-20 token standards across 9+ supported chains.

Aggregated Total Balance

Get instant total stablecoin holdings across all chains and tokens in a single denominated value. Automatically aggregates balances from all supported networks and stablecoins, providing real-time portfolio valuation without manual calculation or separate price feed integrations.

Flexible Filtering and Categorization

Filter results by chain, token symbol, contract address, or stablecoin category (fiat-backed, crypto-collateralized, algorithmic). Tailor responses to specific application needs without additional processing.

Built for Performance and Flexibility

Execute parallel queries across chains with intelligent timeout handling and automatic address detection. Filter results by chain, token symbol, contract address, or stablecoin category (fiat-backed, crypto-collateralized, algorithmic)

Getting Started

You can make JSON-RPC calls to any endpoint with the add-on installed to get stablecoin balances. The endpoint's chain does not matter, the call will return stablecoin balances across chains

getSupportedStablecoins
Returns all supported chains and stablecoins with their contract addresses and metadata.

Multi-Chain Balance Queries
Query stablecoin balances across 9+ blockchain networks with a single API callGet comprehensive balance data for any wallet address across Ethereum, Polygon, BSC, Arbitrum, Optimism, Avalanche, Base, Solana, and Tron. The API automatically detects address type (EVM, Solana, or Tron) and returns results fast.
Advanced Filtering & Categorization
Refine queries using multiple filter dimensions: specific chains (e.g., only Ethereum and Polygon), token symbols (e.g., USDT, USDC), contract addresses, or stablecoin categories including peg type (USD, EUR, JPY), backing type (fiat-backed, crypto-backed, algorithmic), issuer type (centralized, decentralized), and VM type (EVM, SVM, TVM). Ideal for compliance monitoring, risk assessment, and targeted portfolio tracking.
Comprehensive Stablecoin Coverage
Query balances for USDT, USDC, USDC.e, DAI, USDS, FRAX, PYUSD, and 20+ additional stablecoins across multiple chains. Coverage includes fiat-backed tokens (Circle, Tether, Paxos), crypto-collateralized stablecoins (MakerDAO, Aave, Liquity), and algorithmic variants. Automatically handles chain-specific token standards (ERC-20, SPL, TRC-20, BEP-20) and decimal conversions.
