# Deployment Contracts

> Current testnet implementation, behavior, authorization, and Rust signatures.

The core Deployer and lending-pool Deployer are separate admin-controlled contracts.

## Core deployment

`deploy_all` deploys Registry, RateModel, RiskEngine, Oracle, and AccountManager; sets the SmartAccount WASM hash; and wires core addresses. It accepts the Reflector address explicitly. A one-time deployed guard prevents repeating the core deployment. The return order is **Registry, RateModel, RiskEngine, Oracle, AccountManager**.

## Lending deployment

`DeployerLPoolContract` provides a legacy XLM/USDC pair deployment and `deploy_single_pool` for additional markets. It deploys a pool and receipt, initializes metadata, and initializes the pool. A single-pool deployment still needs appropriate Registry asset/alias/permission configuration; it does not onboard every dependency automatically.

The legacy two-pool helper initializes vXLM with 7 decimals and vUSDC with 6; this is not a universal claim about the four configured receipt deployments or underlying SAC decimals. Read deployed metadata.

The Rust workspace uses Soroban SDK **25.3.1**, Blend SDK **2.25.0**, and contract imports from `target/wasm32v1-none/release`. Build prerequisite WASMs before consumers. Review the repository's deployment scripts before using them; addresses listed here are configuration snapshots, not a new deployment.

## Function signatures

These signatures are copied from the reviewed Rust implementation. `env` is supplied by Soroban and is not a transaction argument. `Result` errors and panics must be handled by the caller; simulation does not guarantee later execution. Public methods include privileged and internal-contract callbacks, not just user entrypoints.
