+# Namespace for Supra chains
+
+## Introduction
+
+Blockchains in the "supra" namespace are identified by their numeric `chain_id`;
+each network is maintained by a set of validators with its own REST RPC
+endpoints. Supra is a Layer 1 blockchain built on Move, with vertically
+integrated services — native price oracles, distributed verifiable randomness
+(dVRF), and on-chain automation.
+
+## Syntax
+
+The namespace "supra" refers to the Supra open-source blockchain platform.

+
+# CAIP-2
+
+*For context, see the [CAIP-2][] specification.*
+
+## Rationale
+
+In CAIP-2 a general blockchain identification scheme is defined. This is the
+implementation of CAIP-2 for Supra. Blockchains in the "supra" namespace are
+identified by their numeric `chain_id`, assigned at genesis. Each network is
+maintained by a set of validators with its own REST RPC endpoints. These chain
+IDs require no transformations to be used as conformant CAIP-2 references.
+
+## Syntax
+
+The namespace "supra" refers to the Supra open-source blockchain platform.
+
+### Reference Definition
+
+The definition for this namespace will use the `chain_id` as an identifier
+for different Supra chains. The chain ID is a positive integer assigned at
+genesis:
+
+| Network | Chain ID |
+|---------|----------|
+| Mainnet | 8        |
+| Testnet | 6        |
+
+### Resolution Method
+
+To resolve a blockchain reference for the Supra namespace, make an HTTP GET
+request to the REST RPC of a fullnode, for example:
+
+```bash
+curl https://rpc-mainnet.supra.com/rpc/v3/transactions/chain_id
+```
+
+```jsonc
+// Response
+8
+```
+
+The response is the `chain_id` as an integer that can be used directly as the
+CAIP-2 reference.
+
+### Backwards Compatibility
+
+Not applicable
+
+## Test Cases
+
+This is a list of manually composed examples
+
+```bash
+# Supra Mainnet
+supra:8
+
+# Supra Testnet
+supra:6
+
+```
