Backpack enhances liquidity for tokenized equities with dynamic supply model on Solana

Backpack Securities has built something that looks a lot like the stablecoin playbook, except instead of dollars, it works with actual equities. Users can mint tokenized versions of stocks by depositing real shares, then redeem them back whenever they want, keeping the onchain token supply elastic and pegged to genuine underlying assets.

The model has caught on faster than most expected. Total tokenized equity supply across Solana hit $684 million as of September 11, 2026, and the platform crossed $1 billion in trading volume during July alone.

How the mint-and-redeem model works

Think of it like a coat check for stocks. You hand over your shares, get a token receipt that trades freely onchain, and reclaim your shares whenever you’re done. The 1:1 backing means these tokens aren’t synthetic derivatives or price trackers. They represent real ownership of the underlying equity, held in custody.

This redeemability anchors the token price to the actual share price, since arbitrageurs will step in whenever the two diverge, and lets supply expand or contract based on demand.

Dividends don’t get lost in the translation either. When a company pays out, Backpack automatically adjusts token balances in users’ onchain accounts to reflect the reinvestment.

The platform launched its tokenized equity initiative in June 2026, starting with SPCX, a tokenized version of SpaceX timed to coincide with the company’s Nasdaq listing. Since then, Backpack has expanded to over thirty tokenized equities, with recent additions including MU, MRNA, and NKE. September alone saw twenty new tokenized stocks added to the roster.

Liquidity mechanics that actually compete

Backpack’s answer is a partnership with the Sunrise liquidity protocol, which deploys what it calls proprietary automated market makers, or propAMMs. Unlike standard AMMs that rely on static bonding curves, propAMMs pull pricing data from offchain engines and update approximately every 100 milliseconds.

In one recent week, Backpack recorded $193 million in DEX trading volume. More striking: Backpack commanded 73% of issuer-level volume during that period, despite holding a smaller share of total tokenized supply compared to competitors.

Why after-hours trading matters here

The propAMM structure provides what Backpack describes as defensive liquidity mechanics during off-hours windows. Because the pricing engine continues to operate and the AMM maintains liquidity reserves, traders can execute during periods when traditional venues would offer significantly worse conditions.

The competitive landscape for tokenized equities

Backpack Securities operates as a regulated brokerage, which means the tokenized equities exist within a compliance framework rather than in a legal gray zone. By offering real ownership rather than synthetic exposure, and by wrapping it in a brokerage structure with proper custody arrangements, Backpack is positioning itself for the segment of the market that cares about legitimacy as much as convenience.
