Supported Blockchains Overview

Multi-Chain Architecture

SSP Wallet supports 15 blockchain networks (plus testnets) with true multisignature capabilities across UTXO and EVM-compatible blockchains. Each network uses the optimal implementation:

UTXO Networks: Native P2SH/P2WSH multisignature addresses
EVM Networks: Standard EOA addresses with Schnorr multisig message signing
Account Abstraction: Optional smart contract wallets on supported EVM chains

All networks maintain the same 2-of-2 multisignature security model using BIP48 key derivation.

🌍 Network Selection & Switching

Automatic Network Detection

SSP Wallet automatically detects the appropriate network based on:

Transaction recipient address format
Token contract address
User preference settings
dApp requested network

Manual Network Switching

// Request network switch
await sspProvider.request({
  method: 'wallet_switchEthereumChain',
  params: [{ chainId: '0x89' }] // Polygon
});

// Add custom network
await sspProvider.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x2105', // Base
    chainName: 'Base',
    nativeCurrency: {
      name: 'Ether',
      symbol: 'ETH', 
      decimals: 18
    },
    rpcUrls: ['https://mainnet.base.org'],
    blockExplorerUrls: ['https://basescan.org']
  }]
});

Polygon/BSC: Frequent trading, gaming, low-value transfers
Avalanche/Base: DeFi with better UX, moderate fees
Testnets: Always test before mainnet transactions

For Developers

Test on testnets first before mainnet deployment
Consider fee structures for your application's use case
Plan for network congestion during high-traffic periods
Implement network switching for better user experience
Monitor network health and have fallback options
