Token

The ShiftCTRL Tab Protocol creates various types of ERC-20 tokens to serve different purposes:

Governance Token

ShiftCTRL's native CTRL token is used as the governance token. It is ERC-20 compatible and has a hard cap of 1 billion (1,000,000,000) tokens.

Tab Token

At inception, the Tab Protocol supports 155 Tab currencies.

For more details, please refer to the Tab addresses here.

Note: Each Tab is associated with a riskPenaltyPerFrame value (default 1.5%), which determines the risk penalty amount charged to a vault if the vault's reserve ratio falls below the configured threshold (default 180%). These values can be updated through governance by calling the GovernanceAction.updateTabParams function.

Tab Factory

All Tab contracts are deployed by the Tab Factory using SKYBIT Keyless Deployment method. This approach ensures that Tab token addresses remain consistent across EVM chains.

Tab Registry

The Tab Registry contract is responsible for managing Tabs within the protocol. The ShiftCTRL community can propose changes to the Tab Registry, such as disabling or enabling Tabs, or creating new ones, by submitting a proposal to call a function in the GovernanceAction contract.

To create a Tab pegged to a national currency not currently supported in the Tab Protocol, submit a proposal that calls GovernanceAction.createNewTab. It's crucial to ensure that at least three corresponding oracle feeds are available for the oracle to derive an exchange rate for the new Tab. Without these feeds, the new Tab will remain in a frozen state.

To create a new Tab that is pegged to another existing Tab (e.g., sUSD), the proposal must include two actions: GovernanceAction.createNewTab to create the new Tab, and GovernanceAction.setPeggedTab to link the new Tab to an existing one.
