The mnemonic/wallet generation was using a constant zero-byte array for entropy ([0u8; 32]), making all wallets deterministic based
solely on the password. This commit introduces proper random entropy using OsRng and enables users to back up their recovery phrase.
Changes:
- SeedHolder::new_mnemonic() now uses OsRng for 256-bit random entropy and returns the generated mnemonic
- Added SeedHolder::from_mnemonic() to recover a wallet from an existing mnemonic phrase
- WalletChainStore::new_storage() returns the mnemonic for user backup
- Added WalletChainStore::restore_storage() for recovery from a mnemonic
- WalletCore::new_init_storage() now returns the mnemonic
- Renamed reset_storage to restore_storage, which accepts a mnemonic for recovery
- CLI displays the recovery phrase when a new wallet is created
- RestoreKeys command now prompts for the mnemonic phrase via read_mnemonic_from_stdin()
Note: The password parameter is retained for future storage encryption but is no longer used in seed derivation (empty passphrase is used
instead). This means the mnemonic alone is sufficient to recover accounts.
Usage:
On first wallet initialization, users will see:
IMPORTANT: Write down your recovery phrase and store it securely.
This is the only way to recover your wallet if you lose access.
Recovery phrase:
word1 word2 word3 ... word24
To restore keys:
wallet restore-keys --depth 5
Input recovery phrase: <24 words>
Input password: <password>
Introduce the ATA program, which derives deterministic per-token holding
accounts from (owner, token_definition) via SHA256, eliminating the need
to manually create and track holding account IDs.
Program (programs/associated_token_account/):
- Create, Transfer, and Burn instructions with PDA-based authorization
- Deterministic address derivation: SHA256(owner || definition) → seed → AccountId
- Idempotent Create (no-op if ATA already exists)
Wallet CLI (`wallet ata`):
- `address` — derive ATA address locally (no network call)
- `create` — initialize an ATA on-chain
- `send` — transfer tokens from owner's ATA to a recipient
- `burn` — burn tokens from owner's ATA
- `list` — query ATAs across multiple token definitions
Usage:
wallet deploy-program artifacts/program_methods/associated_token_account.bin
wallet ata address --owner <ID> --token-definition <DEF_ID>
wallet ata create --owner Public/<ID> --token-definition <DEF_ID>
wallet ata send --from Public/<ID> --token-definition <DEF_ID> --to <RECIPIENT> --amount 100
wallet ata burn --holder Public/<ID> --token-definition <DEF_ID> --amount 50
wallet ata list --owner <ID> --token-definition <DEF1> <DEF2>

- can add a label to own account via `wallet` CLI
- labels are displayed with `wallet account get` command
- labels are displayed with `wallet account list` command
- labels are persisted.
