Trust Developer
WalletConsole utility
The Wallet Core library comes with an interactive command-line utility, for accessing key- and address management functionality of the library.

$ ./build/walletconsole/walletconsole
Wallet-Core Console (c) TrustWallet
Type 'help' for list of commands.
> help
. . .
newKey Create new pseudo-random 32-byte key (secret!)
. . .
> coin btc
Set active coin to: bitcoin
> addrDefault
Result: bc1q2kecrqfvzj7l6phet956whxkvathsvsgn7twav

The utility builds together with the library and can be started from: build/walletconsole/walletconsole . See build instructions.
Walletconsole can be also executed 'off the shelf' using the Docker image:
docker run -i -t trustwallet/wallet-core /wallet-core/build/walletconsole/walletconsole

Here is a snapshot of the commands:
exit Exit
quit Exit
help This help
Inputs, buffer:
# Take last result
#<n> Take nth previous result
buffer Take buffer values
coins List known coins
coin <coin> Set active coin, selected by its ID or symbol or name
newKey Create new pseudo-random 32-byte key (secret!)
pubPri <priKey> Derive public key from a secret private key (type is coin-dependent)
priPub <pubKey> Derive private key from public key :)
setMnemonic <word1> ... Set current mnemonic, several words (secret!)
newMnemonic <strength> Create and store a new mnemonic, of strength (128 -- 256) (secret!)
dumpSeed Dump the seed of the current mnemonic (secret!)
dumpMnemonic Dump the current mnemonic (secret!)
dumpDP Dump the default derivation path of the current coin (ex.: m/84'/0'/0'/0/0)
priDP [<derivPath>] Derive a new private key for the coin, from the current mnemonic and given derivation path.
If derivation path is missing, the default one is used (see dumpDP).
addrPub <pubKey> Create <coin> address from public key
addrPri <priKey> Create <coin> address from private key
addr <addr> Check string <coin> address
addrDefault Derive default address, for current coin, fom current mnemonic; see dumpDP
addrDP <derivPath> Derive a new address with the given derivation path (using current coin and mnemonic)
Coin-specific methods:
tonInitMsg <priKey> Build TON account initialization message.
hex <inp> Encode given string to hex
base64Encode <inp> Encode given hex data to Base64
base64Decode <inp> Decode given Base64 string to hex data
File methods:
fileW <fileName> <data> Write data to a (new) binary file.
fileR <fileName> Read data from a binary file.

Here are various sample usages.
Create a new private key, derive a BTC address from it, write it to a file:
> coin bitcoin
Set active coin to: bitcoin Use 'coin' to change. (name: 'bitcoin' symbol: btc numericalid: 0)
> newKey

Check an ALGO address for validity:
> coin algo
Set active coin to: algorand Use 'coin' to change. (name: 'algorand' symbol: algo numericalid: 283)
Derive private keys using different BIP39 derivation paths, and create address from it:
> coin btc
Set active coin to: bitcoin Use 'coin' to change. (name: 'bitcoin' symbol: btc numericalid: 0)
> dumpDP
Result: m/84'/0'/0'/0/0
> priDP
