# Robinhood Chain Wallet | Self-Custodial RWA Wallet for iOS, Android & APK > Gem Wallet is a self-custodial Robinhood Chain wallet for iOS, Android, and APK. Hold, send, and swap ETH and ERC-20 tokens on Robinhood's Ethereum Layer-2 - open-source, no accounts, no KYC. ## What Is Robinhood Chain? Robinhood Chain is a permissionless, Ethereum-compatible Layer-2 blockchain built to bring traditional markets, crypto, and real-world assets together on a single open network. It is designed for the seamless transfer, access, and management of digital assets worldwide, without intermediaries or platform lock-in. As a Layer-2, it settles to Ethereum for security while processing transactions off the mainnet for faster finality and lower costs. The network is optimized for tokenized real-world assets (RWAs) - including equities, ETFs, private assets, and other financial instruments - so they can be represented and traded onchain. This supports a model where assets are programmatically traded, self-custodied by users, and accessible 24/7. A public testnet is live for developers, with a broader rollout planned through 2026. ## What Is a Robinhood Chain Wallet? A Robinhood Chain wallet is an app that lets you create and use an Ethereum-style address to hold, send, and receive ETH and ERC-20 tokens on Robinhood Chain without leaving your assets on a centralized platform. Because Robinhood Chain uses ETH as its native gas token, you keep a small amount of ETH on hand to cover transaction fees. A self-custodial Robinhood Chain wallet means the private keys stay on your device, so you - and only you - control the funds. Gem Wallet is a self-custodial wallet for Robinhood Chain and other EVM networks, available on iOS, Android, and APK. It gives you an Ethereum-compatible address from a single 12-word recovery phrase, lets you send, receive, and swap ETH and ERC-20 tokens, and never asks for an email, account, or KYC. Gem Wallet is open-source and independently audited, so anyone can verify how it protects your keys. ## Robinhood Chain Wallet Features in Gem Wallet - Full Self-Custody: Gem Wallet keeps your private keys on your device, secured by a single 12-word recovery phrase that also covers Ethereum and every other supported network. - Ethereum-Compatible by Design: Gem Wallet is built for EVM chains, so the same address format and ERC-20 token support that power Ethereum and Arbitrum apply to Robinhood Chain. - ETH for Gas: Gem Wallet lets you hold ETH to cover Robinhood Chain transaction fees, and shows the exact fee in ETH and USD before you confirm. - Built-In DEX Aggregator: Gem Wallet lets you swap ETH and ERC-20 tokens for other assets right inside the app through an integrated decentralized exchange aggregator - no separate swap site needed. - Buy Crypto with a Card: Gem Wallet lets you buy ETH with a credit or debit card and other payment methods, credited straight to your wallet. - Open Source & Audited: Gem Wallet is fully open-source and independently audited, giving you transparency that closed platforms cannot. ## Built for Tokenized Real-World Assets Robinhood Chain is purpose-built for tokenized real-world assets, letting equities, ETFs, and private assets be issued as ERC-20-style tokens that move onchain like any other digital asset. Because these tokens follow Ethereum standards, a self-custodial wallet that supports ERC-20 can hold and transfer them directly. Gem Wallet is a self-custodial DeFi wallet for EVM networks, so it gives you the same key control over tokenized assets on Robinhood Chain that it gives you over ETH and USDT. ## How Robinhood Chain Works Robinhood Chain is built on Arbitrum Orbit, a modular Layer-2 framework that combines Ethereum's security with high throughput and low transaction costs. It uses Ethereum blobs for data availability and ETH as the native gas token, with finality and fees far better than transacting directly on Ethereum mainnet. The network is permissionless and developer-friendly: anyone can interact with it, build applications, and deploy smart contracts. The testnet runs on Chain ID 46630 with ETH as its currency symbol.
