How to Add Networks to Coinbase Wallet? Which Chains Are Supported?

Supported Networks in Coinbase Wallet

1. Ethereum Mainnet is natively supported with full compatibility for ETH, ERC-20 tokens, and smart contract interactions.

2. Base network appears by default after wallet initialization, enabling seamless transfers of ETH and bridged assets without manual configuration.

3. Arbitrum One and Optimism are pre-enabled, allowing users to interact with DeFi protocols and NFT marketplaces directly from the wallet interface.

4. Polygon PoS is integrated as a standard option, supporting fast low-cost transactions and native MATIC staking features.

5. Robinhood Chain is not pre-loaded but fully compatible via custom RPC addition using its official parameters: RPC URL https://rpc.mainnet.chain.robinhood.com, Chain ID 4663, currency symbol ETH.

Manual Network Addition Process

1. Open Coinbase Wallet and tap the profile icon in the top-right corner to access settings.

2. Select “Networks” then choose “Add Network” to begin configuration.

3. Input the network name exactly as specified by official documentation — for example, “Robinhood Chain” must match case and spacing used by the chain’s team.

4. Paste the correct RPC endpoint; entering an invalid or outdated URL will result in failed transaction submissions and unresponsive balance displays.

5. Confirm Chain ID matches the mainnet specification — for Robinhood Chain it is strictly 4663, while testnet uses 46630.

Verification Steps After Configuration

1. Switch to the newly added network within the wallet interface and verify that the network indicator changes color or displays a confirmation badge.

2. Check if ETH balance reflects correctly — zero balance may indicate incorrect RPC connectivity rather than absence of funds.

3. Initiate a small test transaction to confirm gas estimation works and block confirmations appear on-chain via the embedded explorer link.

4. Attempt to connect to a DApp hosted on the same chain; failure to authenticate suggests missing EIP-1559 support or misaligned chain parameters.

5. Review the displayed block explorer URL — for Robinhood Chain it must resolve to https://robinhoodchain.blockscout.com and show recent blocks matching current height.

Common Misconfigurations to Avoid

1. Using Ethereum’s Chain ID (1) instead of Robinhood Chain’s dedicated identifier (4663) causes signature rejection during transaction signing.

2. Copying RPC URLs from unofficial forums introduces proxy endpoints that log private keys or inject malicious payloads into signed messages.

3. Omitting trailing slashes or adding extra spaces in the RPC URL breaks wallet initialization and returns vague “network error” messages.

4. Selecting “Ethereum” as currency symbol when configuring Robinhood Chain leads to incorrect gas price calculation and failed ETH transfers.

5. Confusing Base’s Chain ID (8453) with Robinhood Chain’s (4663) results in asset routing errors where ETH sent from Coinbase Wallet arrives on the wrong L2 network.

Frequently Asked Questions

Q: Does Coinbase Wallet support automatic detection of new EVM-compatible chains like Robinhood Chain?A: No. Automatic detection is disabled for security reasons. Users must manually input verified RPC details for each non-preloaded chain.

Q: Can I store both ETH and WETH on Robinhood Chain using Coinbase Wallet?A: Yes. The wallet treats WETH as a standard ERC-20 token on Robinhood Chain and allows wrapping/unwrapping through integrated interfaces.

Q: Why does my balance show zero after adding Robinhood Chain even though I confirmed ETH was sent there?A: This typically occurs when the RPC endpoint fails to sync historical state. Try switching to another RPC provider listed in official documentation or clearing local cache in wallet settings.

Q: Is it safe to reuse the same mnemonic phrase across multiple networks in Coinbase Wallet?A: Yes. The wallet derives addresses deterministically per chain using BIP-44 paths. Each network isolates key derivation, preventing cross-chain exposure.
