Chain ID

A chain ID is a unique identifier that represents a blockchain network. We use it to distinguish different blockchain networks from each other and to ensure that transactions and messages are sent to the correct network. Slinky network follows the format of identifier_EIP155-version format.

Official Chain IDs

Mainnet

Name	Chain ID	Identifier	Version	Active
Slinky Hyperloop	88335	slinky	-	🚫

Testnet

Name	Chain ID	Identifier	Version	Active
Slinky Neo Testnet	88338	slinky	1	✅

The Chain Identifier

Every chain must have a unique identifier or chain-id. Tendermint requires each application to define its own chain-id in the genesis.json fields. However, in order to comply with both EIP155 and Cosmos standard for chain upgrades, Slinky-compatible chains must implement a special structure for their chain identifiers.

Structure

The Slinky Chain ID contains 3 main components

• Identifier: Unstructured string that defines the name of the application.

• EIP155 Number: Immutable EIP155 CHAIN_ID that defines the replay attack protection number.

• Version Number: Is the version number (always positive) that the chain is currently running. This number MUST be incremented every time the chain is upgraded or forked in order to avoid network or consensus errors.

Format

The format for specifying the Slinky-compatible chain-id in genesis is the following:

{identifier}_{EIP155}-{version}

The following are ChainIDs for Slinky Mainnet and Slinky Testnet:

Name	ChainID	Identifier	EIP155 Number	Version Number
Slinky Hyperloop Mainnet	slinky_88335-1	slinky	88335	-
Slinky Neo Testnet	slinky_88338-1	slinky	88338	1
