Backpack Boosts Tokenized Equity Liquidity with Dynamic Supply Model on Solana

Backpack Securities has introduced an innovative model to enhance liquidity for tokenized equities on the Solana blockchain. By allowing users to mint tokenized versions of stocks, deposit real shares, and redeem them back whenever they want, the platform has created a dynamic supply model that keeps the onchain token supply elastic and pegged to genuine underlying assets.

Total tokenized equity supply across Solana hit $684 million as of September 11, 2026, with the platform crossing $1 billion in trading volume during July alone. The mint-and-redeem model works like a 'coat check for stocks,' where users hand over shares, get a token receipt that trades freely onchain, and reclaim their shares whenever they're done.

The 1:1 backing of these tokens means they represent real ownership of the underlying equity, held in custody. Dividends are automatically adjusted to reflect reinvestment, ensuring no loss in translation. The platform has expanded to over thirty tokenized equities since its launch in June 2026, with recent additions including MU, MRNA, and NKE.

To provide competitive liquidity mechanics, Backpack has partnered with the Sunrise protocol's automated market makers (propAMMs), which update pricing data from offchain engines approximately every 100 milliseconds. In one week, Backpack recorded $193 million in DEX trading volume, commanding 73% of issuer-level volume despite holding a smaller share of total tokenized supply compared to competitors.

The propAMM structure provides defensive liquidity mechanics during off-hours windows, allowing traders to execute trades when traditional venues would offer worse conditions. By operating as a regulated brokerage, Backpack ensures the tokenized equities exist within a compliance framework rather than in a legal gray zone.
