IGRA/WiKAS

Igra Bridged Kaspa (iKAS) is the native gas token of Igra Network, an EVM-compatible, based-rollup execution layer built on top of Kaspa, a proof-of-work BlockDAG Layer 1. Each iKAS represents one KAS bridged from Kaspa Layer 1 and is backed 1:1 by KAS locked in Igra's canonical bridge contracts on Kaspa. iKAS is used to pay transaction fees, deploy and interact with smart contracts, and settle value within the Igra Network ecosystem. Igra Network is a based rollup, meaning transaction sequencing is delegated to Kaspa's Layer 1 consensus rather than performed by a standalone sequencer. This design inherits Kaspa's proof-of-work security, leaderless BlockDAG ordering, and MEV-resistance properties while adding an EVM execution environment derived from Reth. The network targets over 3,000 transactions per second with sub-second inclusion latency and supports standard Ethereum tooling such as Hardhat, Foundry, MetaMask, and the JSON-RPC interface. A security audit of the core protocol was performed by Sigma Prime. Users obtain iKAS by bridging KAS from Kaspa Layer 1 through Igra's canonical bridge, which locks KAS in a dedicated entry address on Kaspa and mints an equivalent amount of iKAS to the user's address on Igra. The bridge is symmetric, allowing iKAS to be burned on Igra and redeemed for KAS on Kaspa. iKAS has 18 decimals on Igra to preserve standard ERC-20/native-gas precision, while KAS on Kaspa has 8 decimals; the bridge handles the conversion between the two representations.
