Kasplex

Kasplex is asset-issuance and indexing infrastructure for Kaspa, defining the KRC-20 fungible token standard and KRC-721 NFTs. Token instructions are written into Kaspa transactions via P2SH and read by an offchain open-source indexer that determines balances, so assets can be issued without touching layer-one consensus while avoiding UTXO bloat.

The stack includes open APIs, a data-availability layer and an extra fee paid to miners on deployment and minting to discourage meaningless writes. An EVM layer two built on the same indexer maps KRC-20 assets into a smart-contract environment. The indexer was once bypassed because it did not strictly validate script format: forged transfers using an empty signature plus OP_NOT moved 186 million ZEAL and 54.4 billion NACHO out of a bridge custody address, wiping 94% to 99.6% of the KAS-side value in affected pools, after which iKAS withdrawals and Hyperlane transfers were paused.
