Balance Auditor

Enter seed phrases and API keys to derive EVM addresses and fetch real balances across multiple supported chains and cryptocurrencies. Or, use the automatic generator.

Critical Security Warning & Usage Notice

NEVER enter REAL seed phrases from wallets with significant funds into ANY online tool you do not fully trust and haven't audited.This application is for demonstration and educational purposes.

It uses ethers.js for LOCAL address derivation (primarily EVM-compatible). Your seed phrases are NOT sent to any server for derivation.
It WILL attempt to use provided API keys/credentials to fetch REAL balances:
- Etherscan: For Ethereum (ETH) mainnet.
- BlockCypher: For ETH, BTC, LTC, DOGE, DASH (using the derived EVM address for all queries).
- Alchemy: For various EVM-compatible chains like Ethereum, Polygon, Arbitrum, Optimism, Base.
- Blockstream & Mempool.space: For Bitcoin (BTC) mainnet.
- Solana: For Solana (SOL) mainnet via public RPC.
- CryptoAPIs.io: For BTC, ETH, LTC, DOGE, DASH and other chains supported by their API.
- Mobula.io: For portfolio tracking across various chains. (Placeholder implementation for API call)
- Moralis: For EVM native, token balances, and Tron (TRX/TRC20) balances.
- TronGrid: For Tron (TRX) and TRC20 token balances.
Addresses derived are EVM-compatible. Querying non-EVM chains (e.g., BTC, Solana or Tron) with an EVM address may not yield expected results for those specific non-EVM assets but is attempted. For accurate non-EVM balances from a seed phrase, a chain-specific derivation path is required, which is beyond this tool's current scope.
If API keys/credentials are missing, invalid, rate-limited, or calls fail, results may show 0 balance or "N/A" datasource. Manual checks without keys are ineffective for real balances.
The automatic generator REQUIRES at least one set of API credentials to function and find real balances.
Exposing real seed phrases can lead to PERMANENT LOSS OF FUNDS. Pre-filled API keys/credentials are for demonstration and may be rate-limited or revoked. Use your own for reliable use.

Input Seed Phrases & API Credentials

Provide seed phrases (one per line, up to 1000) and your API credentials. At least one set of API credentials is needed for the automatic generator to find real balances.

Etherscan API

For Ethereum (ETH) mainnet balances.

BlockCypher API

Checks ETH, BTC, LTC, DOGE, DASH.

Alchemy API

ETH, Polygon, Arbitrum, Optimism, Base etc.

BTC & Solana

Mempool/Blockstream for BTC, Public RPC for Solana. No keys needed.

Other APIs & Database

Provide credentials for other balance providers. Found wallets are automatically saved to the database configured in your .env file.

CryptoAPIs.io API

For various chains like BTC, ETH, LTC etc.

Moralis API

For EVM, Tron (TRC20), and token balances.

Mobula.io API

For multi-chain portfolio balances.

TronGrid API

Alternative for Tron (TRX) balances.

Check Single Address Balance

Enter any cryptocurrency address to check its balance across all configured APIs.

AI Auto-Completion

Enter the first two words of a seed phrase, and the AI will continuously generate and check valid phrases starting with those words until you stop it.Requires at least one set of API credentials.

SESSION TOTAL CHECKED

STATUS

Stopped

Automatic Seed Phrase Inspector

Continuously generates and checks random seed phrases. The batch size below (default 20, max 100) controls the number of phrases requested from the AI in each step.Requires at least one set of API credentials.Generator state (count, status, batch size) is persisted across refreshes unless explicitly stopped.
