Protocol
Network and contracts
SATOZ runs on BNB Chain, the high-throughput EVM chain built for tokenized stocks and real-world assets.
Why BNB Chain
SATOZ lends against tokenized stocks, so it lives where those assets are issued. BNB Chain is a permissionless, EVM-compatible chain built for high-throughput settlement. Solidity contracts use standard EVM tooling, compatible wallets can connect directly, and gas is paid in BNB.
The public mainnet RPC is www.satozec.org/rpc. It is rate limited, so production traffic should use dedicated infrastructure.
Real assets on the chain
BNB Stock Tokens are standard ERC-20 assets that compatible applications can hold, transfer, and compose. KYB onboarding applies to the authorized participants who mint and redeem the tokens. This standard interface allows SATOZ to evaluate supported Stock Tokens as collateral. Corporate actions arrive through the ERC-8056 scaled amount extension rather than rebasing, and every stock token ships a per-asset Chainlink feed whose price already includes that multiplier. SATOZ reads those feeds directly.
The chain settles around 
USDT alongside bridged stablecoins, and an onchain asset registry enumerates every listed stock token. The pool contract takes its stable asset as a constructor parameter, so the deployed pool can denominate in whichever stablecoin has the deepest local liquidity; on mainnet that is USDT.

Contract architecture
SatozPool
The core. A USDT stability pool with Liquity-style accounting, per-asset collateral configuration, one-time fees, partial liquidation with a keeper incentive, and an optional passport gate on every draw.
PartnershipDesk
The profit and loss sharing track. Partnerships are funded pro rata, capital moves to the operator on activation, returns are reported onchain, settlement can require an independent auditor's approval, and profit splits at the agreed ratio while genuine losses fall on the capital.
PassportRegistry
The credit passport anchor. Approved attesters write a five-check bitmask with optional expiry; the pool and any integrated platform can require a complete passport without seeing the data behind it.
Collateral control plane
The app is the control plane over these contracts: one view of collateral health, available credit, pool deposits, partnership stakes, and every attestation in force, read directly from chain state. Nothing shown there exists anywhere except onchain.
Status
The core contracts and automated keeper are implemented. The test suite covers accounting, liquidation, partnership settlement, price feeds, and stale-price safeguards. Independent review, production configuration, and mainnet deployment remain required release steps.
