t2000: Rebalance (Yield Optimizer)
Purpose
Automatically find and execute the best yield across NAVI and Suilend. Internally optimizes across all 4 stablecoins (USDC, suiUSDT, suiUSDe, USDsui) — the user doesn't need to think about which stablecoin to hold. One command moves savings from a lower-yielding position to the highest available rate, handling withdrawals, swaps, and deposits in sequence.
Command
t2000 rebalance --dry-run # preview the plan without executing
t2000 rebalance # execute (prompts for confirmation)
t2000 rebalance --yes # skip confirmation prompt (for agents)
# With custom thresholds:
t2000 rebalance --min-diff 1.0 # only act on 1%+ APY difference
t2000 rebalance --max-break-even 14 # skip if break-even > 14 days
t2000 rebalance --dry-run --json # machine-readable planWorkflow
- Always run
--dry-runfirst to see the plan - Review the economics (APY gain, swap cost, break-even days)
- Run without
--dry-runto execute (or add--yesfor agents)
Output (dry-run)
Rebalance Plan
──────────────────────────────────────
From: USDC on NAVI Protocol (4.21% APY)
To: suiUSDT on Suilend (5.40% APY)
Amount: $1,000.00
Economics
──────────────────────────────────────

Annual Gain: $11.90/year
Swap Cost: ~$0.30
Break-even: 9 days
Steps
──────────────────────────────────────
1. Withdraw $1,000.00 USDC from navi
2. Swap USDC → suiUSDT (~$999.70)
3. Deposit $999.70 suiUSDT into suilend

| Flag | Description | Default |
|---|---|---|
--dry-run | Preview without executing | false |
--min-diff <pct> | Minimum APY difference to trigger | 0.5% |
--max-break-even <days> | Max break-even days for cross-asset moves | 30 |
--yes | Skip confirmation prompt | false |
--json | Machine-readable output | false |
Safety
- Health factor check: refuses to rebalance if HF < 1.5 (active borrows)
- Break-even filter: skips cross-asset moves with break-even > 30 days
- Minimum yield difference: ignores gains below 0.5% by default
- Confirmation prompt before execution (use
--yesto skip for agents) - If any step fails, stops and reports state
When to use
- Periodically (weekly/monthly) to optimize yield
- After rate changes on protocols
- When new stablecoins offer higher yields
- After
t2000 saveto potentially upgrade to a better rate
Notes
- Same-asset rebalance (e.g., USDC from NAVI → Suilend): no swap needed, zero cost
- Cross-asset rebalance (e.g., USDC → suiUSDT): swap cost factored into break-even
- Multi-stablecoin optimization is handled internally — users save/withdraw in USDC only
- Withdraw always returns USDC (auto-swaps non-USDC positions back)
