Klever Namespace - Chains

CAIP-2

For context, see the CAIP-2 specification.

Abstract

In CAIP-2 a general blockchain identification scheme is defined. This document is the implementation of CAIP-2 for the Klever blockchain.

Klever Namespace

The namespace klv refers to the wider Klever ecosystem.

Rationale

The Klever protocol runs a production network (Mainnet), a testing network (Testnet) and a development network (Devnet). More may be canonically addressed in the future. Each network is identified on-chain by an integer klv_chain_id assigned at genesis; that integer is the canonical CAIP-2 reference.

Syntax

An identifier for a Klever chain consists of the namespace prefix klv: followed by the chain’s integer klv_chain_id.

Reference Definition

The reference is the network’s integer chain ID, rendered in base 10 with no leading zeros:

• 108 for Mainnet
• 109 for Testnet
• 100001 for Devnet

References are within the case-sensitive [-a-zA-Z0-9]{1,32} envelope mandated by CAIP-2.

Resolution Method

To resolve a blockchain reference for the Klever namespace, query the /node/status endpoint on any public Klever node, e.g. the official mainnet node:

// Request
curl -sS https://node.mainnet.klever.org/node/status

// Response (formatted, excerpt)
{
  "data": {
    "metrics": {
      "klv_chain_id": 108
      // ... other live chain metrics
    }
  },
  "code": "successful"
}

The klv_chain_id field inside data.metrics is the value used directly as the reference section of a CAIP-2 or CAIP-10.

Backwards Compatibility

Not applicable.

Test Cases

# Klever Mainnet
klv:108

# Klever Testnet
klv:109

# Klever Devnet
klv:100001
