App Name: LumpTools
App URL: https://lumptools.xyz/midnight
Category: tools

LumpTools is a token explorer for Midnight and Cardano: live prices, charts, liquidity, holders, on-chain activity and wallet portfolios, built on our own Midnight and Cardano nodes and indexers. On Midnight, every Pulse pool paired with NIGHT is priced from its public contract state, with no third-party market API. There is also a Midnight project directory, which already lists 1AM.

1AM integration (DApp Connector API v4). Midnight pages have a Connect Wallet button that lists every wallet under window.midnight (1AM first-class, Lace also works) and calls connect('mainnet'), then hintUsage for the read methods it uses. The wallet page (#midnight/wallet) reads getUnshieldedBalances, getShieldedBalances and getDustBalance and prices them from the LumpTools Midnight market, including Pulse's bridged colours (wNIGHT, wADA, wUSDCx). It uses getConfiguration to confirm mainnet and getConnectionStatus to notice a revoked session. Connector errors show 1AM's own reason (e.g. the network-mismatch message). LumpTools only reads: it never asks the wallet to sign, balance or submit anything, and balances stay in the browser.

Tested on mainnet in the 1AM mobile in-app browser: connect, approval, and balances (wNIGHT + DUST) all work. On desktop, Cardano pages also list 1AM's CIP-30 provider for the Cardano portfolio.

Icon. A 128x128 PNG (14.1KB) is added at icons/lumptools.png. The same mark is served from our domain at https://lumptools.xyz/favicon.png. The copy is in icons/ because the extension's img-src CSP only allows raw.githubusercontent.com, *.1am.xyz and IPFS gateways, so an icon hosted on another domain falls back to the two-letter tile in the Apps tab.

node validate.js passes locally.
