Simple Summary

This document is about the details of the Solana namespace and reference for CAIP-2.

Abstract

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

Motivation

See CAIP-2.

Specification

Solana Namespace

The namespace "solana" refers to the Solana open-source blockchain platform.

Reference Definition

The definition for this namespace will use the genesisHash as an indentifier for different Solana chains. The method for calculating the chain ID is as follows with pseudo-code:

Resolution Method

To resolve a blockchain reference for the Solana namespace, make a JSON-RPC request to the blockchain node with method getGenesisHash, for example:

The response will return as a value for the result a hash for the block with height 0 that should be truncated to its first 32 characters to be CAIP-30 compatible.

Rationale

Blockchains in the "solana" namespace are identified by their chain ID as mentioned in the Reference Definition Section.
