Backpack Securities Opens Mint and Redeem API to All Solana Developers

Backpack has opened its Securities mint and redeem API to all developers building on Solana, removing the access barrier between the platform's tokenized-stock issuance layer and the broader builder community. CEO Armani Ferrante made the announcement on September 13.

Previously, the infrastructure that converts a security entitlement into an on-chain token was not accessible to outside teams. Any Solana developer can now call a single endpoint to mint a tokenized security or redeem it back into its underlying entitlement, without a separate custody arrangement.

How the Backpack Securities Mint and Redeem API Works

Each token issued through Backpack Securities represents a claim on an SPV holding the real underlying shares. Traditional securities on the platform are held as UCC Article 8 entitlements under New York law, and the 1:1 redemption mechanism keeps the token price anchored to the underlying equity rather than floating on supply and demand alone.

The API uses ED25519 keypair authentication. Every request requires three headers: X-API-Key (the base64-encoded public key), X-Signature (a base64-encoded signature covering the request), and X-Timestamp (milliseconds). The same authentication model covers the rest of the Backpack Exchange API surface, including the securities discovery endpoint at GET /api/v1/securities.

Because each token stays redeemable 1:1 for the real share, applications built on top of the API carry the same direct-redemption guarantee as tokens Backpack issues through its own products. That changes the calculus for developers building stock-adjacent financial products on Solana: custody is handled, and issuance is one signed request away.

STOCKLANA Hackathon: $100K for Builders Across Five Infrastructure Categories

The API opening coincides with the STOCKLANA hackathon, a Solana Foundation event running through September 18 with $100K in prizes. The five prize categories span trading infrastructure, investing tools, credit and yield products, backend infrastructure, and consumer applications.

With 26 submissions already in, the hackathon is a coordinated builder push squarely aimed at tokenized equity infrastructure on Solana. Open API access gives participants a path from a working prototype to a production-ready issuance pipeline without separately negotiating custody infrastructure.

Solana's tokenized equity segment has grown rapidly in parallel. Tokenized equity supply on Solana reached a record $684M earlier this week, with 41 stocks currently listed across Backpack Securities.
