Use your wallet on a new network
Any network in the app’s list works. If your network is not listed, you can add a custom EVM network. Your address is the same on every EVM network, so you do not create a new wallet.
Requirements
The network must be EVM and must support what the wallet needs:
- ERC-4337 EntryPoint v0.7 at the standard address.
- The Kernel v3.3 wallet contracts and the passkey (WebAuthn) validator, deployed at their standard addresses.
- A bundler endpoint.
- Optional: a P-256 signature-check precompile (RIP-7212 ). Without it, passkey signatures are checked in contract code and fees are higher.
1. Open Add custom network
Open Wallet → Networks → Add custom network.
2. Enter the RPC URL
Enter the network’s RPC URL. The app reads the chain ID from the RPC and verifies it. You can also enter an optional bundler URL.
3. Let the app check the network
The app checks the contracts on-chain and tells you whether the network can host the wallet. If it cannot, the app gives you the reason, such as a missing EntryPoint or a missing validator.
4. Fund your address
Open Receive, pick the new network and send some of its native coin to your address. The address is the same as on your other EVM networks.
5. Make your first send
Your first send on the network sets the wallet up there (it is “deployed”). A one-time setup fee applies, paid from your balance of the network’s native coin. After that, sends only pay the normal network fee.
Receiving works before setup. Funds sent to your address on the network before the wallet is set up are safe at your address.
If the contracts are missing on a chain
If the check says the EntryPoint, the Kernel contracts or the validator are not on the chain, the wallet cannot run there yet. Someone must first deploy the canonical contracts. The ERC-4337 and ZeroDev deterministic deployers let anyone deploy them at the standard addresses. See the public deployment docs:
After they are deployed, run the check again.
Troubleshooting
No bundler
The app cannot send without a bundler. Enter a bundler URL for the network when you add it, or edit the network and add one. Make sure the bundler supports EntryPoint v0.7 on that chain.
Chain ID mismatch
The chain ID the RPC returns must match the network you entered. Check that the RPC URL belongs to the right network and that you did not paste a testnet URL for a mainnet.
The fee seems high
If the network has no P-256 precompile (RIP-7212), the passkey signature is verified in contract code, which costs more gas. This is expected. The network operator must add the precompile to lower it.
Funds were sent before setup
They are safe. Your address exists on every EVM network, and funds sent there stay yours. Fund the address with the native coin, then make your first send to set the wallet up.
