# Guide: Core Marketplace

## Quick Overview

b14g Merge Marketplace connects BABY and BTC holders so they can **dual-stake together** and share rewards.

**For BTC holders:** Lock your BTC on the Bitcoin network (self-custodial) and match with CORE holders to unlock higher yield tiers.

**For CORE holders:** Browse open BTC orders on the marketplace, then match your CORE stake with an order you prefer, earn dual-staking rewards without needing to acquire BTC.
