Overview

When Dokrypt starts a local chain, it automatically creates and funds a set of test accounts. You can manage these accounts and create new ones at any time.

​
Default Accounts

By default, Dokrypt creates 10 accounts funded with 10,000 ETH each. Configure this in dokrypt.yaml: 
settings:
  accounts: 10              # Number of accounts
  account_balance: "10000"  # ETH per account
Or per chain: 
chains:
  ethereum:
    engine: anvil
    chain_id: 31337
    accounts: 20
    balance: "50000"

​
Listing Accounts

dokrypt accounts list

#   Address                                    Balance (ETH)
1   0x70997970C51812dc3A010C7d01b50e0d17dc79C8  10000.00
2   0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC  10000.00
3   0x90F79bf6EB2c4f870365E785982E1f101E93b906  10000.00
4   0x15d34AAf54267DB7D7c367839AAf71A00a2C6A65  10000.00
5   0x9965507D1a55bcC2695C58ba16FB37d819B0A4dc  10000.00

​
Funding Accounts

Set any account’s balance: 
dokrypt accounts fund 0x1234...abcd 1000
The amount is in ETH. This replaces the current balance (it doesn’t add to it).

​
Impersonating Accounts

Allow transactions from any address without the private key: 
dokrypt accounts impersonate 0xdead...beef
Useful for:
  • Interacting with contracts as their owner
  • Simulating transactions from whale addresses
  • Testing governance as specific voters

​
Generating Accounts

Create additional funded accounts: 
dokrypt accounts generate 5
Generates 5 deterministic addresses, each funded with 10,000 ETH.

​
Multi-Chain

All account commands support --chain for multi-chain setups: 
dokrypt accounts list --chain polygon
dokrypt accounts fund 0x1234... 500 --chain arbitrum
dokrypt accounts generate 10 --chain ethereum

​
Account Generation

Dokrypt generates accounts deterministically from a seed. This means:
  • The same accounts are generated every time
  • Accounts are reproducible across machines
  • Private keys are derived using ECDSA/secp256k1
  • Addresses use EIP-55 checksumming
