Supported Networks
SubWallet provides comprehensive support for major blockchain ecosystems and their networks.Substrate Chains
Full support for Polkadot, Kusama, and their parachains:- Relay Chains: Polkadot, Kusama, Westend
- Parachains: Acala, Moonbeam, Astar, Parallel, Bifrost, HydraDX, and many more
- Solo Chains: Substrate-based chains not connected to a relay chain
EVM-Compatible Chains
Connect to Ethereum and EVM networks:- Ethereum Mainnet and Testnets
- Layer 2 Solutions: Arbitrum, Optimism, Base, Polygon
- EVM Parachains: Moonbeam, Moonriver, Astar EVM
- Other EVM Chains: BSC, Avalanche, Fantom, and more
Additional Ecosystems
TON Network
Native support for The Open Network (TON), including TON coin transfers and token management.
Cardano
Connect to Cardano networks with support for ADA transfers and native assets.
Bitcoin
Bitcoin mainnet and testnet support for BTC transactions.
Managing Networks
Enabling and Disabling Networks
Control which networks appear in your wallet:Browse or search networks
Find networks by name, or browse by ecosystem (Polkadot, Kusama, Ethereum).
Custom Networks
Add networks that aren’t in SubWallet’s default list:- For EVM Chains: Provide the chain ID, RPC URL, currency symbol, and block explorer URL
- For Substrate Chains: Enter the chain name, RPC endpoint, and optionally the token decimals and symbol
Network Endpoints
SubWallet connects to each network through RPC endpoints:- Default Endpoints: Pre-configured, tested endpoints for each network
- Custom Endpoints: Add your own RPC endpoints for better performance or privacy
- Endpoint Selection: Switch between multiple endpoints if the current one is slow or down
Endpoint health is monitored automatically. If an endpoint becomes unavailable, SubWallet attempts to reconnect or you can manually switch to an alternative.
Chain Features
Automatic Chain Detection
When you create or import accounts, SubWallet automatically detects compatible networks:- Substrate Accounts: Work with all Polkadot and Kusama ecosystem chains
- Ethereum Accounts: Compatible with all EVM networks
- Specialized Accounts: TON, Cardano, and Bitcoin accounts for their respective networks
Chain-Specific Metadata
SubWallet maintains accurate metadata for each network:- Native token symbol and decimals
- Block explorers for transaction viewing
- Chain logos and branding
- Network type and capabilities
Network Status Monitoring
Stay informed about network connectivity:Connected
Network is online and ready for transactions
Connecting
Establishing connection to network endpoint
Disconnected
Network is unavailable or endpoint is down
Multi-Chain Account Management
Unified Account View
With unified accounts, your single seed phrase creates addresses for multiple networks:- View all network balances in one account
- Switch networks without changing accounts
- Manage assets across ecosystems seamlessly
Network-Specific Addresses
Each network may use different address formats:- Substrate: SS58 format (starts with different characters based on the chain)
- Ethereum: Hex format (starts with 0x)
- Bitcoin: Base58 or Bech32 format
- TON: Base64 format
Cross-Chain Features
Asset Discovery
SubWallet automatically discovers your assets across all enabled networks:- Native tokens on each chain
- Custom tokens and smart contract tokens
- NFTs on supported networks
Network Switching
Quickly switch between networks when:- Sending tokens or NFTs
- Connecting to dApps
- Viewing transaction history
- Managing staking positions
Multi-Chain Transactions
Perform actions across different networks:- Transfer tokens from one network to another (cross-chain transfers)
- Swap tokens across chains
- Stake on multiple networks simultaneously
Network Organization
Grouping by Ecosystem
Networks are organized by their ecosystem:- Polkadot Ecosystem: Polkadot relay chain and parachains
- Kusama Ecosystem: Kusama relay chain and parachains
- Ethereum Ecosystem: Ethereum and EVM-compatible chains
- Independent Chains: Standalone networks not part of a larger ecosystem
Test Networks
Access testnets for development and testing:- Westend (Polkadot testnet)
- Rococo (Parachain testnet)
- Ethereum Sepolia and Goerli
- Other network-specific testnets
Performance Optimization
Selective Network Loading
SubWallet only loads data for enabled networks, which:- Reduces memory usage
- Speeds up wallet startup
- Improves overall performance
Connection Management
Network connections are intelligently managed:- Active networks maintain persistent connections
- Inactive networks disconnect to save resources
- Automatic reconnection when networks become active
Best Practices
Enable Only What You Use
Enable Only What You Use
Keep your enabled networks list focused on chains you actively use. This reduces clutter and improves performance.
Verify Network Before Transactions
Verify Network Before Transactions
Always double-check which network you’re using before sending assets. Sending to the wrong network can result in lost funds.
Use Custom Endpoints for Privacy
Use Custom Endpoints for Privacy
If privacy is important, consider running your own RPC endpoint or using a trusted private endpoint.
Keep Endpoint Lists Updated
Keep Endpoint Lists Updated
Periodically check for new endpoints if you experience slow connections. Network operators often add new infrastructure.
Test Network First
Test Network First
When working with new networks or dApps, test with small amounts first to ensure everything works as expected.
