Why We Built on Solana

When we started building Prilana Pay, we evaluated every major blockchain. The requirements were simple: sub-second transaction finality, fees low enough that micropayments are viable, and a developer ecosystem mature enough to build a production payment gateway. One chain met all three.

Speed: sub-second finality

Solana's block time is approximately 400 milliseconds. A payment transaction confirms in under a second. For a payment gateway, this is non-negotiable. When a buyer clicks “Pay,” they expect instant confirmation. They expect the content to unlock immediately. Any delay breaks the user experience.

Compare this to other chains. Ethereum averages 12-15 seconds per block, and most applications recommend waiting for multiple confirmations. Bitcoin takes 10 minutes per block, with 6 confirmations recommended for finality. Even Layer 2 solutions like Polygon or Arbitrum have seconds of latency and rely on Ethereum for final settlement. Solana confirms and finalizes in under a second, on the base layer, with no rollup complexity.

Cost: fractions of a cent

A Solana transaction costs approximately 0.000005 SOL — at current prices, roughly $0.001. This means the network fee for a Prilana payment is effectively zero. The buyer pays nothing extra for the on-chain transaction. The merchant's 3% fee covers the protocol — Solana's network fee is negligible.

This matters enormously for micropayments. If you're paying $2.99 for a single piece of content, a $5-15 gas fee (common on Ethereum during busy periods) makes the transaction absurd. On Solana, a $2.99 payment costs $2.99 plus a fraction of a penny in network fees. Micropayments actually work.

SPL tokens: native token support

$PRLN is a standard Solana SPL token. SPL is Solana's token standard — equivalent to ERC-20 on Ethereum, but with lower fees and faster transfers. Every Solana wallet natively supports SPL tokens. There's no special setup required. If you have Phantom, Solflare, or Backpack, you can hold and transfer $PRLN out of the box.

Program Derived Addresses for verification

Prilana's age verification credentials are stored as Program Derived Addresses (PDAs) on Solana. A PDA is an on-chain account that's controlled by a smart contract (called a “program” on Solana) rather than a private key. This means the verification credential is tamper-proof — only the Prilana verification program can create or modify it.

When a merchant checks if a wallet is age-verified, they read the PDA directly from the blockchain. No API call. No database query. No latency. The check happens on-chain, in the same transaction as the payment. This is only practical on a chain with Solana's speed and cost profile.

The developer ecosystem

Solana has mature tooling for building payment applications. The Anchor framework simplifies smart contract development. Wallet adapter libraries handle connections to every major wallet. The Solana Pay specification provides a standard for point-of-sale transactions. We built on top of a proven stack rather than inventing everything from scratch.

Why not Ethereum?

Ethereum is the most established smart contract platform, but it's too slow and too expensive for a payment gateway. Even with Layer 2 solutions, the user experience involves bridging assets, waiting for finality, and paying higher fees than Solana's base layer. For a product where the buyer expects instant confirmation and the merchant expects instant settlement, Ethereum's architecture adds unnecessary friction.

The bottom line

Solana lets us build a payment experience that feels like a credit card swipe: instant confirmation, negligible fees, and no technical overhead for the user. The buyer clicks, approves in their wallet, and the content unlocks. The merchant sees the payment in their wallet immediately. That's only possible on Solana.
