Network References

Each network in OneBalance is identified using the CAIP-2 chain ID format:
  • Format: {namespace}:{chainId}
  • Example: eip155:1 for Ethereum Mainnet or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp for Solana Mainnet
When using the OneBalance API, you’ll reference these networks using their CAIP-2 identifiers.
