Demo custodian wallets and the operator flow for judging are documented in Judge Demo Access. Custodian private keys are not published publicly; the trading flow remains self-serve with any Arbitrum Sepolia wallet.

Overview

A Note on Development: This project was built with strict architectural oversight. While AI tools were leveraged to accelerate development, every line of code was explicitly directed, reviewed, and deeply understood. There is no 'vibecoding' here. AI acts solely as a velocity multiplier for a deliberately engineered system.

PulsarFi tokenizes Indonesian public equities into pStock tokens on Arbitrum Sepolia. Each pStock represents custodian-backed IDX exposure, priced through IDX market data and traded against IDRX liquidity.

The product surface is intentionally compact:

• Markets: browse pStocks, IDX prices, IHSG, and token detail pages.
• Portfolio: view wallet holdings, transfers, swaps, and redemption requests.
• Custodian console: submit mint proposals, attest reserves, and manage redemption access.
• Protocol: mint, approve, execute, and redeem pStocks through smart contracts.
