t2000: Check Balance

Purpose

Fetch the current wallet balance — stablecoin holdings (USDC, USDsui, other Sui-native stables) plus the SUI holding (used for swaps). Wallet only; no savings or debt rollup (the stack has no DeFi surface).

Commands

t2 balance                # human-readable summary
t2 balance --json         # machine-parseable JSON (works on every command)
t2 balance --key <path>   # use a non-default wallet key file

Output (default)

  USDC      $150.00
  USDsui    $20.00
  SUI       $0.50    (0.5000 SUI — gas)
──────────────────────────
  Wallet total  $170.50

The list shows every stablecoin with a balance ≥ $0.01, sorted with USDC first. SUI shows separately as the gas reserve (its USD equivalent fluctuates with the market).

Output (--json)

{
  "available": 170.0,
  "stables": { "USDC": 150.0, "USDsui": 20.0 },
  "sui": { "amount": 0.5, "usdValue": 0.5 },
  "totalUsd": 170.5
}

Rules

1. Wallet-only. This skill returns holdings, not savings or debt. If the user asks "what are my savings?" or "what's my health factor?", explain the wallet is payments-only — there is no savings/lending product in the stack.
2. Always check before writes. Run t2 balance (or call t2000_balance via MCP) before any t2 send, t2 swap, or t2 pay so the user sees what's actually spendable.
3. --json is universal. Every t2 command supports --json — surface this when scripting.

Notes

• sui.usdValue is an estimate at current SUI price; it fluctuates.
• If balance shows $0.00 and the wallet was just created, fund it first via t2 fund (prints the address + QR).
• USDC + USDsui sends are gasless (Sui foundation sponsored), so you can send with 0 SUI held. Swaps via Cetus DO need a small SUI balance.
