MIKODES components#

MIKODES Admin Kit 0.4.0 in admin/packages/admin-kit/: the author's own code and part of this item, covered by the same Envato licence (see admin/packages/admin-kit/LICENSE.md). The console's source is in ui-src/; ui/ is its unminified build.
keccak-256 in terminal/src/keccak.js: written for this product, checked against three published test vectors.
Design system in design-system/: written for this product.

Fonts#

Inter and JetBrains Mono, SIL Open Font License 1.1, loaded from Google Fonts by the stylesheets. Not bundled.
Geist and Geist Mono (Vercel), SIL Open Font License 1.1, bundled as .woff2 files in admin/packages/admin-kit/ui/assets/ (licence texts Geist-OFL.txt and GeistMono-OFL.txt next to them) for the admin console.

Polymarket and Kalshi material#

API shapes, the Polymarket fee formula and the builder-code field were read from Polymarket's MIT-licensed SDKs (Polymarket/ts-sdk, py-sdk, rs-clob-client-v2, clob-client-v2). File and line references are in the source comments. No SDK code is bundled.
terminal/src/exchangeV2.abi.ts holds the ABI of Polymarket's CTF Exchange V2. It matches the ABI shipped in the MIT-licensed Polymarket/clob-client-v2 (src/order-utils/abi/ExchangeV2.ts) by name and purpose; the file carries no attribution header and is not imported by any shipped code. The event decoders in onchain.js use the event signatures directly.
Not used, on purpose: @polymarket/builder-relayer-client (no licence) and the Polymarket/ctf-exchange-v2 contract repository (BUSL-1.1).
Market data from Kalshi, Polymarket and the Polygon blockchain is fetched at run time and is subject to each provider's terms. None of it is bundled other than the data files the refresh job commits to your repository.
Kalshi's fee constants cite Kalshi's public documentation (fee rounding page and the 2026-08-22 changelog).

Trademarks#
