Why PulsarFi

Indonesian public equities are large, liquid, and familiar to local investors, but they do not naturally fit crypto-native workflows. PulsarFi exists to make IDX equity exposure programmable without pretending that compliance and custody do not matter.

Market context

IDX equity access is still tied to traditional market structure:

• trading happens within exchange hours;
• investors cannot exit while the market is closed;
• overnight macro shocks can reprice risk before the local market opens;
• pre-opening gaps can push stocks directly into downside price limits;
• brokerage onboarding is jurisdiction-specific;
• exchange settlement and withdrawable cash follow securities settlement timing;
• portfolio positions are trapped inside broker interfaces;
• assets are not composable with DeFi rails;
• international crypto-native users cannot easily interact with Indonesian equities.

In Indonesian market language, ARB usually refers to Auto Rejection Bawah, where sell orders below the exchange's lower price boundary are automatically rejected. For international readers, this is closest to a single-stock downside price limit or limit-down style price band. It is not exactly the same as the U.S. Limit Up-Limit Down mechanism, but the economic effect is similar: when price protection bands are hit, users may not be able to exit at the price or time they want.

This matters most around market close and pre-open:

global macro shock after IDX close
    -> user cannot sell the underlying stock overnight
    -> pre-open reprices the stock lower
    -> downside price limit / ARB can reject lower sell orders
    -> broker exit is delayed even before T+2 cash settlement

This creates a gap between two markets:

Traditional IDX market	Crypto-native market
Strong real-world asset base	24/7 global accessibility
Regulated custody and T+2-style settlement	Fast self-custody transfers
Broker-centric UX	Wallet-centric UX
Limited composability	Programmable asset flows
Compliance built into account access	Compliance usually built into gateways

PulsarFi is designed to bridge these strengths rather than replace one side with the other.

Product thesis

Most tokenized asset products fall into one of two weak patterns:

1. They become too permissioned, making every interaction feel like a traditional brokerage wrapped in a wallet.
2. They become too synthetic, giving users a token that tracks price but does not represent an accountable off-chain asset position.

PulsarFi avoids both extremes:

• trading and holding are permissionless;
• redemption is compliance-gated;
• minting is custodian-controlled;
• supply creation is tied to custody records;
• liquidity is created directly on-chain.

Compliance problem

KYC is important when a user exits from an on-chain receipt into an off-chain regulated asset. However, requiring KYC before a user can hold or swap a receipt token makes the product harder to use and reduces liquidity.

PulsarFi uses a gateway model:

Action	KYC required?	Reason
Hold pStock	No	Holding an ERC-20 receipt is permissionless.
Transfer pStock	No	ERC-20 transferability is preserved.
Swap pStock and IDRX	No	Trading happens through the pool.
Request redemption	Yes	The user is entering the off-chain securities delivery process.
Approve KYC	Custodian only	Custodians control redemption eligibility.

This keeps the entry path open while enforcing compliance at the point where it matters.

Currency problem

The underlying assets are Indonesian equities, and Indonesian equities are Rupiah-denominated. If the protocol used USDC as the default pool asset, users would need to reason about two things at once: stock exposure and USD/IDR FX.

PulsarFi uses IDRX to keep the product locally coherent:

• IDX reference prices are in Rupiah.
• User portfolio value can be shown in Rupiah terms.
• Custodian reporting and redemption accounting are naturally IDR-based.
• The product creates real demand for Rupiah stablecoin adoption.
• Pool prices can be compared to IDX reference prices without a USD conversion step.

The choice is strategic. PulsarFi is not only bringing Indonesian equities on-chain; it is also giving Rupiah stablecoin rails a concrete financial use case.

Exit liquidity problem

Traditional equity settlement creates two separate exit frictions:

1. Trading exit: the investor needs an open market and executable price.
2. Cash exit: after the trade, cash availability follows the securities settlement cycle.

IDX-listed equities use exchange settlement timing rather than instant wallet settlement. In practice, this means a user can be exposed to overnight risk, pre-open repricing, downside price limits, and delayed cash availability.

Profit is not withdrawable cash

In a brokerage account, selling a profitable stock position does not mean the user can withdraw the cash immediately. The trade can show realized profit in the broker interface, but regular-market cash availability still follows the securities settlement cycle.

For IDX regular-market equities, settlement is commonly T+2: the transaction is settled two exchange days after the trade date. That creates a practical capital lock:

profitable stock sale
    -> profit appears in broker account
    -> cash is not withdrawable on the same day
    -> user waits for T+2-style settlement
    -> capital cannot be redeployed or withdrawn instantly

This is one of the core reasons PulsarFi uses an IDRX-denominated on-chain receipt market. A user exiting a pStock position receives wallet-settled IDRX from the pool instead of waiting for brokerage cash settlement.

PulsarFi does not claim to remove the underlying market's custody requirements. Instead, it creates an on-chain secondary exit path: a user can swap pStock against IDRX liquidity even when the traditional brokerage exit path is slower or temporarily constrained.

Liquidity integrity problem

If a protocol mints receipt tokens directly to an operator wallet without matching liquidity, the first seller can drain the pool and break the expected relationship between the receipt and the underlying asset. For this reason, PulsarFi sends new mints into the liquidity pool with IDRX funding.

The result is a stricter minting rule:

new pStock supply must be paired with IDRX liquidity

This is why mint proposals include both tokenAmount and idrxAmount.

Trust model

PulsarFi does not claim to remove all trust. It makes trust explicit.

Party	Trusted for	Not trusted for
Custodians	Holding and attesting off-chain shares.	Unilaterally minting supply.
Protocol admin	Configuration and upgrades.	Bypassing custodian mint thresholds.
Backend	Displaying operational records.	Executing token transfers or minting.
User wallet	Signing transactions.	Receiving redemption without KYC.
AMM pool	Executing swaps.	Guaranteeing exact IDX price at all times.

The system reduces unilateral risk by requiring custodian threshold approval for mint and redemption execution.
