PAR turns securities held across compatible accounts into inventory borrowers can rely on. Holders set the limits; borrowers reserve specific stock; PAR keeps each obligation connected through return.
Stock becomes dependable lending supply when a holder authorizes a defined quantity, eligible borrowers, price and term.
PAR connects that authorization to demand, reserves specific inventory and keeps delivery, servicing and return connected across compatible accounts and venues.
Securities lending is PAR’s first application of a broader availability and obligations layer for portable securities.
The holder authorizes a quantity, minimum rate, maximum duration and whether the offer is firm. A firm offer reserves the shares; a soft offer leaves them available until a borrower takes the loan.
Agents publish and search the available inventory on behalf of market makers and liquidity providers. When the stock, fee and term fit, the borrower can take the loan.
The borrower posts collateral and receives the stock. The assets move only as each side has authorized.
The borrower returns the stock and the holder receives the fee. The stock can then be offered again. If it is not returned on time, anyone can enforce the loan.
PAR coordinates the loan. It does not own the stock or become the counterparty.
Tokenized stocks trade across venues and outside exchange hours. The stock and hedges behind them are not always available at the same time. That creates an inventory problem.
Tokenized stocks may keep trading after the underlying exchange closes or when new tokens can't be issued or redeemed. Market makers then have fewer ways to source stock and correct a price gap.
Some tokens are held in AMM pools, vaults or other strategies. They count as supply, but they are already committed elsewhere. Borrowers need to know what holders are willing and able to lend.
Keeping inventory for every market ties up capital. Borrowing gives a desk access to stock when it needs to quote or hedge, without carrying the position indefinitely.
Perpetuals and options create exposure without delivering a share. The firms behind those markets may still borrow stock to hedge positions or trade price differences. Derivatives can increase borrow demand rather than remove it.
Earn a lending fee on stock you already hold. Set the terms once, keep control of the mandate and make returned stock available again without repeating the whole process.
Locate stock, compare borrowing terms and reserve the inventory you need. Borrowed tokens can be used in supported trading, hedging and settlement workflows, subject to the token, the receiving venue, participant eligibility and the loan terms.
Give market makers a way to source inventory when markets move. Better access to stock borrow can support tighter spreads, deeper books and more reliable pricing.
Financing supply can begin in holder-controlled accounts, integrated platform accounts or shared pools. Each requires a different route to market.
PAR coordinates holder-controlled inventory. Integrated platforms can embed financing within their own account systems. Pooled protocols allocate assets already organized under common rules. PAR can connect authorized inventory to compatible financing venues when pooled execution is useful.
B20 securities can move across investor and custody accounts, professional inventories and onchain venues. PAR connects holder-authorized inventory across this account-linked structure.
Base provides a foundation for connected onchain capital markets, where securities remain portable while financing and servicing work across the ecosystem.
PAR is a pre-launch testnet prototype. The underlying contracts are deployed on Base Sepolia, where complete loan-and-return cycles have run. The desk interface, balances, rates, order book and counterparties are simulated unless explicitly marked LIVE.
