Unified EVM Address

All supported EVM networks share a single, unified address format. A single EVM wallet address can receive assets across multiple EVM-compatible chains and tokens.

Protocol Address Behavior

Protocol Model	Address Behavior
EVM Networks	One wallet address shared across supported EVM-compatible blockchains and tokens.
Solana	Wallet addresses are unique to the Solana network.
Bitcoin	Wallet addresses are unique to the Bitcoin network.
Other Networks	Wallet addresses are protocol-specific and isolated per blockchain network.

How It Works

Wallet addresses are generated and managed based on blockchain protocol groups rather than individual chains. When you create a wallet on an EVM chain (such as BASE) using a specific reference ID (refId), an EVM address is generated:

{
  "accountId": "e29b41d4a7164440",
  "refId": "550e8400-e29b-41d4-a716-446655440000",
  "blockchain": "BASE"
}

If you subsequently issue another wallet creation request using the same refId on a different EVM network (such as ETH or POLYGON), OpenXSwitch returns the same EVM wallet address:

{
  "accountId": "e29b41d4a7164440",
  "refId": "550e8400-e29b-41d4-a716-446655440000",
  "blockchain": "ETH"
}

This architecture allows developers to:

Reuse EVM Addresses: Reuse a single refId to maintain a consistent address per user across all supported EVM chains.
Isolate Addresses: Pass distinct refId values to generate isolated wallet addresses per user or operational strategy.
