Technology Stack

Starzip is built on opBNB and combines an off-chain matching engine with on-chain settlement. The goal is centralized-exchange speed and usability, with the transparency and self-custody guarantees of a public blockchain.

Built on opBNB

opBNB is a high-throughput, low-fee Layer 2 on BNB Chain, fully EVM-compatible. It lets Starzip settle trades, launchpad escrow, and reward distributions on-chain at a cost low enough for everyday retail activity, without sacrificing composability with the broader EVM ecosystem.

Hybrid Exchange Architecture

Order matching runs off-chain for low-latency execution, while every trade settles on-chain. This hybrid split delivers responsive trading UX while keeping settlement, fee distribution, and the issuer revenue share verifiable on-chain.

Smart Contract Suite

Core protocol logic lives in audited on-chain contracts. Each is purpose-built and independently verifiable.

• Settlement contract — finalizes matched trades and distributes trading fees, routing the issuer share to each store automatically.
• Launchpad escrow contract — holds committed funds during the offering window and auto-refunds participants in full if the soft cap is not reached.
• Governance contracts — execute passed proposals on-chain after a timelock for both the Starzip DEX DAO and per-business Store DAOs.

Account Models

Starzip supports two account paths suited to different users.

• Self-custody wallet — traders and investors connect their own wallet, keeping full custody of assets. Store Tokens can be swapped for USDT on the DEX at any time as a liquid exit path.
• Smart Account onboarding — businesses issuing a Store Token are onboarded via an ERC-4337 smart account, so they can deploy and operate on-chain without managing seed phrases or gas mechanics directly.
