# Migrate

## Overview

Migrate provides an automated flow for users who stake on Ethereum Sepolia and move into Goliath Testnet via Slingshot.

**Access:** <https://slingshot.goliath.net/#/migrate>

## What Changed

* Users can now stake on Sepolia and migrate through a guided flow in Slingshot.
* This reduces manual steps between Sepolia staking and Goliath participation.

## User Flow

1. Connect wallet to Sepolia
2. Open Slingshot `/#/migrate`
3. Select amount and execute Sepolia staking/migration prompts
4. Wait for backend processing and destination finalization
5. Switch to Goliath and confirm resulting balance/state

## Developer Notes

* The migrate flow spans two chains; monitor both source and destination transactions.
* Keep chain-specific decimal handling explicit (XCN inside EVM uses tinyxcn-scale accounting).
* Use explorer-verified ABIs and avoid hard-coding unpublished contracts.
