• The links in this paragraph still reference {{dependencies.repositories.polkadot_sdk_contracts_node.commit_dev_node}}, which points to a specific commit hash (8e2b6f742a38bb13688e12abacded0aab2dbbb23). This creates an inconsistency: the links point to a specific commit, but the instructions below don't check out that commit. Either update these links to point to master or main branch, or restore the git checkout command to match the linked commit.

The Polkadot SDK repository contains both the [Revive Dev node](https://github.com/paritytech/polkadot-sdk/tree/{{dependencies.repositories.polkadot_sdk_contracts_node.commit_dev_node}}/substrate/frame/revive/dev-node){target=\_blank} implementation and the [ETH-RPC adapter](https://github.com/paritytech/polkadot-sdk/tree/{{dependencies.repositories.polkadot_sdk_contracts_node.commit_dev_node}}/substrate/frame/revive/rpc){target=\_blank} required for Ethereum compatibility. Start by cloning the repository and navigating to the project directory:

Removing the git checkout command without pinning to a specific version creates reproducibility issues. Users following this guide will clone the latest main branch, which may contain breaking changes or incompatibilities. Consider either: (1) keeping the checkout command with an updated commit hash, (2) checking out a stable release tag (e.g., git checkout polkadot-stable2409), or (3) documenting which version/branch users should use.

Suggested change

	cd polkadot-sdk
	cd polkadot-sdk
	git checkout polkadot-stable2409
