tusdt-cli 0.1.3

CLI for interacting with the TUSDT ink! smart contract system on subtensor(bittensor)

tusdt-cli

Command-line interface for the TUSDT stablecoin system — a set of ink! smart contracts deployed on the Bittensor (subtensor) network. TUSDT lets users lock native TAO tokens as collateral in vaults to mint a USD-pegged stablecoin. This CLI gives you full control over:

• Vaults — create, deposit collateral, borrow TUSDT, repay, and release collateral
• Token — check balances, transfer TUSDT, and manage spending approvals
• Auctions — browse and bid on liquidation auctions for under-collateralised vaults
• Oracle — inspect the on-chain price feed that determines collateral ratios

No web UI required — everything runs from your terminal.

Installation

pip install tusdt-cli

Local Development Installation

git clone https://github.com/TensorUSD/tusdt-cli
cd tusdt-cli
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
pip install -e .

Or using uv:

git clone https://github.com/TensorUSD/tusdt-cli
cd tusdt-cli
uv sync

Quickstart

The CLI comes pre-configured with the Finney RPC endpoint, contract addresses, and bundled ABI metadata. No upfront configuration is required — pass --wallet-name on any command that needs signing.

# Check CLI version
tusdt --version

# Get help for any command
tusdt --help
tusdt vault --help
tusdt vault create --help

1. List wallets

tusdt wallet list

2. Vault operations

Anywhere an address is expected you can pass a wallet name via --wallet-name and the CLI resolves the SS58 address from coldkeypub.txt automatically or use --owner and supply ss58 address

# Create a vault with 10 TAO as collateral (prompts for coldkey password)
tusdt vault create --amount 10 --wallet-name MyWallet

# View vault #0 (no password needed – reads coldkeypub.txt)
#                ↓vault ID
tusdt vault info 0 --wallet-name MyWallet
tusdt vault info 0 --owner 5GrwvaEF...

# List all vaults for a wallet
tusdt vault list --wallet-name MyWallet
tusdt vault list --owner 5GrwvaEF...

# Add 5 TAO collateral to vault #0
#                          ↓vault ID
tusdt vault add-collateral 0 --amount 5 --wallet-name MyWallet

# Borrow 100 TUSDT from vault #0
#                  ↓vaultID ↓TUSDT amount
tusdt vault borrow 0        100 --wallet-name MyWallet

# Repay 50 TUSDT to vault #0
#                 ↓vault ID ↓TUSDT amount
tusdt vault repay 0         50 --wallet-name MyWallet

# Release 2 TAO collateral from vault #0
#                              ↓vaultID ↓TAO amount
tusdt vault release-collateral 0        2 --wallet-name MyWallet

# Check max borrow capacity for vault #0
#                      ↓vault ID
tusdt vault max-borrow 0 --wallet-name MyWallet

# Check collateral value for vault #0
#                            ↓vault ID
tusdt vault collateral-value 0 --wallet-name MyWallet

3. Token operations

# Check balance (wallet name or SS58 address)
tusdt token balance --wallet-name MyWallet
tusdt token balance --owner 5GrwvaEF...

# Transfer 100 TUSDT to another wallet
#                    ↓recipient (wallet name or SS58)  ↓TUSDT amount
tusdt token transfer RecipientWallet                  100 --wallet-name MyWallet

# Approve a spender to use up to 1000 of your TUSDT
#                   ↓spender(wallet name or SS58) ↓TUSDT amount
tusdt token approve SpenderWallet                 1000 --wallet-name MyWallet

# Check allowance (spender wallet name or SS58 address)
#                     ↓spender
tusdt token allowance SpenderWallet --wallet-name MyWallet
tusdt token allowance SpenderWallet --owner 5GrwvaEF...

4. Auction operations

# List active liquidation auctions
tusdt auction list-active

# View auction details
#                ↓ auction ID
tusdt auction info 0

# Place a 500 TUSDT bid on auction #0
#                 ↓auctionID ↓TUSDT bid amount
tusdt auction bid 0          500 --wallet-name MyWallet --wallet-hotkey default

# Finalize a completed auction
#                      ↓ auction ID
tusdt auction finalize 0 --wallet-name MyWallet

# Withdraw refund for a non-winning bid
#                             ↓auctionID ↓bid ID
tusdt auction withdraw-refund 0          1 --wallet-name MyWallet

# Check your bid on auction #0 (no password, reads coldkeypub.txt)
#                    ↓ auction ID
tusdt auction my-bid 0 --wallet-name MyWallet

5. Oracle operations

# View latest price
tusdt oracle price

# View current round
tusdt oracle round

Network selection

Two networks are available: finney (mainnet, default) and testnet.

# Per-command override (not saved)
tusdt vault list --wallet-name MyWallet --network testnet
tusdt oracle price --network testnet

# Save as default
tusdt config set --network testnet

# Switch back
tusdt config set --network finney

Configuration

Configuration is stored in ~/.tusdt-cli/config.json. Most users won't need to edit it — --wallet-name and --network on each command cover the common cases.

# View current config
tusdt config show

# Pre-configure a wallet (avoids passing --wallet-name every time)
tusdt config set --wallet-name MyWallet

# Use a mnemonic seed phrase instead
tusdt config set --signer "word1 word2 word3 ... word12"

# Override contract addresses or RPC
tusdt config set --rpc wss://custom-endpoint:443
tusdt config set --vault 5Hh...

Transaction output

All write operations (create vault, borrow, transfer, bid, etc.) display a progress spinner and, on success, print the extrinsic hash with a Taostats explorer link:

Finalized
┌─ Transaction ──────────────────────────────────────────────────┐
│  Extrinsic: 0xabc123…                                          │
│  Block: 0xdef456…                                              │
│  Explorer: https://taostats.io/hash/0xabc…?network=finney      │
└────────────────────────────────────────────────────────────────┘

The network parameter in the URL matches the --network flag (or the configured default).
