TapTapSend-style remittance untuk PMI/TKI Indonesia, tapi rail-nya DeFi stablecoin (USDT/USDC) + Xendit/Midtrans untuk payout IDR. PMI di Hong Kong, Singapura, Taiwan, Saudi, UAE, Malaysia kirim USDT, keluarga di Indonesia terima IDR langsung ke BCA/Mandiri/BRI/BNI/GoPay/OVO/DANA/QRIS dalam hitungan menit. Lebih cepat dari Western Union, lebih murah dari Wise, fee lebih tipis dari semua exchange Indonesia karena kita skip exchange.

Krisnala treasury
├─ USDT accumulate di Safe multisig (3-of-5)
├─ Idle balance → Aave V3 (Arbitrum) supply for ~4-6% APY
├─ Threshold $50K → trigger OTC sell ke counterparty
├─ OTC pays IDR ke bank operasional → top-up Xendit/Midtrans float
└─ Hedge IDR/USD exposure jika float > X (perp DEX optional, phase 2)
