+# Soroban Escrow Contract — Deployment Guide
+
+This guide explains how to build and deploy the `escrow` Soroban contract included under `contracts/contracts/escrow` to the Stellar Testnet (Soroban).
+
+Prerequisites
+- Rust + cargo and the `wasm32-unknown-unknown` target installed:
+  - `rustup target add wasm32-unknown-unknown`
+- `soroban` CLI installed and available in your PATH (see https://github.com/stellar/soroban-tools)
+- Network RPC for Soroban testnet (the script defaults to `https://rpc.testnet.soroban.stellar.org`)
+
+Quick build & deploy
+
+1. Build the WASM artifact:
+
+```bash
+cd contracts
+./deploy_escrow_testnet.sh
+```
+
+The script builds the contract and prints the command you can run to deploy using the `soroban` CLI. If you set `AUTO_DEPLOY=1` it will attempt to run the deploy command automatically.
+
+Environment variables
+- `SOROBAN_RPC_URL` — optional. If unset the script uses `https://rpc.testnet.soroban.stellar.org`.
+- `AUTO_DEPLOY=1` — run the deploy command automatically after building.
+
+Example: manual deploy (after building)
+
+```bash
+# deploy the compiled wasm (prints tx hash and contract id)
+soroban contract deploy --wasm contracts/contracts/escrow/target/wasm32-unknown-unknown/release/escrow.wasm
+
+# example: call `fund` as the client (requires the client key available to soroban CLI)
+soroban contract invoke --id <CONTRACT_ID> --fn fund --source <CLIENT_SECRET>
+
+# example: release payment (either client or freelancer can call; pass the caller address as an argument if required)
+soroban contract invoke --id <CONTRACT_ID> --fn release --args <MILESTONE_ID> <CALLER_ADDRESS> --source <CALLER_SECRET>
+
+# example: refund (freelancer invokes)
+soroban contract invoke --id <CONTRACT_ID> --fn refund --args <MILESTONE_ID> <CALLER_ADDRESS> --source <FREELANCER_SECRET>
+```
+
+Notes on contract functions and mapping
+- `initialize(...)` — creates an escrow (maps to requested `create_escrow`).
+- `fund()` — lock funds into the contract (maps to `fund_escrow`).
+- `submit_milestone(milestone_id)` — freelancer submits completed milestone.
+- `approve(milestone_id)` — client approves submitted milestone.
+- `freelancer_confirm(milestone_id)` — freelancer confirms approval.
+- `release(milestone_id, caller)` — releases funds to freelancer (maps to `release_payment`).
+- `refund(milestone_id, caller)` — refunds client (maps to `refund_payment`).
+- `dispute(...)` / `resolve_dispute(...)` — dispute and arbiter resolution.
+
+Integration notes
+- The contract expects an SPL-like token address (`token`) passed at initialization. The contract uses the standard `token::Client` interface for transfers.
+- Constructing the initialization `milestones` vector via CLI can be complex; for integration we recommend using the `@stellar/stellar-sdk` / Soroban client in an application script to upload WASM and call `initialize` with typed arguments.
+
+Replacing the JS stub
+- The repository contains a JS stub at `lib/soroban/deploy.ts`. Replace that stub with an implementation that uploads the compiled WASM, sends the install/create contract transaction, and returns the deployed contract ID and tx hash. See notes in that file for steps.
