FOR EDUCATIONAL PURPOSES ONLY – NOT FOR REAL USE

This tool demonstrates how Trust Wallet and other HD wallets generate seed phrases and derive private keys. NEVER use generated keys for real cryptocurrency. Always use official, trusted wallets for real funds.

BIP-39 Seed Phrase Generator

Generate a 12-word BIP-39 seed phrase using the same algorithm as Trust Wallet.

No Seed Phrase Generated

Click “Generate Seed Phrase” to create a BIP-39 seed phrase using Trust Wallet’s algorithm

Private Key Derivation

Derived private keys from the seed phrase using BIP-32/BIP-44 standards (m/44’/60’/0’/0/0 for Ethereum).

Derived Private Keys

These private keys are derived from the seed phrase using hierarchical deterministic (HD) wallet standards.

1

Seed Phrase โ†’ Seed

Seed phrase is converted to a 512-bit seed using PBKDF2-HMAC-SHA512 with “mnemonic” as salt.

2

Seed โ†’ Master Key

Seed is used to generate master private key and chain code via HMAC-SHA512 with “Bitcoin seed” key.

3

Master โ†’ Derived Keys

Master key derives child keys using BIP-32 standard for different cryptocurrencies.

Trust Wallet Algorithm Explained

BIP-39: Mnemonic Seed Generation

Trust Wallet follows BIP-39 standard for seed phrase generation:

Step 1: Generate Random Entropy
128 bits of random data (for 12 words)
Step 2: Calculate SHA256 Checksum
First 4 bits of SHA256(entropy) are checksum
Step 3: Combine Entropy + Checksum
132 bits total = 128 bits entropy + 4 bits checksum
Step 4: Split into 11-bit chunks
12 chunks of 11 bits each (11 ร— 12 = 132 bits)
Step 5: Map to Wordlist
Each 11-bit number (0-2047) maps to a BIP-39 word

BIP-32: Hierarchical Deterministic Wallets

From seed phrase to private keys:

Step 1: Mnemonic to Seed
PBKDF2-HMAC-SHA512(mnemonic, “mnemonic”, 2048 iterations, 512 bits)
Step 2: Master Key Generation
HMAC-SHA512(key=”Bitcoin seed”, data=seed)
Left 32 bytes = Master Private Key
Right 32 bytes = Chain Code
Step 3: Child Key Derivation
For path: m/44’/60’/0’/0/0
m = master, 44′ = purpose (BIP-44), 60′ = coin type (Ethereum)
0′ = account, 0 = change (external), 0 = address index

Security Considerations for Real Wallets

Real cryptocurrency wallets implement additional security measures:

  • Hardware security modules (HSM) for key storage
  • Secure element chips for key generation
  • Air-gapped environments for sensitive operations
  • Multi-signature setups for large amounts
  • Regular security audits and penetration testing
