[**Robinhood Chain** What Robinhood Chain is (chain id 4663), its block times, gas, L1 settlement, native assets (ETH, WETH, USDG), tokenized stocks, and how Crius indexes it. Read](https://docs.crius.sh/concepts/robinhood-chain/) [**Launchpads** How token launchpads on Robinhood Chain work (bonding curves, graduation to Uniswap pools, LP locks) and which launchpads Crius attributes, including Pons, Flap.sh, Bankr, Long.xyz and Flywheel. Read](https://docs.crius.sh/concepts/launchpads/) [**Uniswap v2, v3 & v4** How Crius indexes Uniswap v2 pairs, v3 concentrated-liquidity pools and v4 singleton pools with hooks on Robinhood Chain, including liquidity definitions and v4 hook permissions. Read](https://docs.crius.sh/concepts/uniswap/) [**Trader attribution & wallet tags** How Crius attributes Robinhood Chain trades to the real trader behind routers, aggregators, bundlers and bot contracts, and what each wallet tag means. Read](https://docs.crius.sh/concepts/attribution/) [**Finality & reorgs** Finality levels on Robinhood Chain (latest, safe, finalized), how the Crius API marks them, and how chain reorganizations are handled in REST and WebSocket. Read](https://docs.crius.sh/concepts/finality/) [**How Robinhood Chain token prices work (confidence and thin liquidity)** How the Crius API prices Robinhood Chain tokens from on-chain pools, how the price pool is picked, and what confidence and thin\_liquidity mean. Read](https://docs.crius.sh/concepts/token-prices/) [**Security score: confidence and limitations** What the Crius security score can and can't see on Robinhood Chain, how to read its confidence fields, and why a low-risk result is not a guarantee a token is safe. Read](https://docs.crius.sh/concepts/security-score-limits/) [**Holder classes on Robinhood Chain: infrastructure, bots, snipers, whales and smart accounts** How the Crius API tells real holders from pools, the PoolManager, lockers and contracts, and how it tags devs, snipers, whales and smart accounts. Read](https://docs.crius.sh/concepts/holder-classes/) [**How trader and wallet PnL is computed on Robinhood Chain** How the Crius API computes realized and unrealized PnL, ROI, cost basis and win rate for Robinhood Chain traders and wallets, worked through on real trades. Read](https://docs.crius.sh/concepts/pnl/) [**How Crius measures token taxes (realized vs simulated)** How Crius measures buy, sell and transfer taxes on Robinhood Chain tokens from real trades and from a simulated buy and sell, how the two are combined, and how tax changes are tracked. Read](https://docs.crius.sh/concepts/taxes/) [**Launch risk: snipers, insiders, wallet farms and uniform holders** How Crius spots insider control of a Robinhood Chain token with a clean contract (snipers, wallet farms, uniform holders, LP control) and the thresholds it uses. Read](https://docs.crius.sh/concepts/launch-risk/) [**Uniswap v4 hook risk: levels, flags and code families** How Crius rates every Uniswap v4 hook on Robinhood Chain, from its permissions, its code and owner, what happened in its pools and its code family's record, with each risk flag and its threshold.
