Five onchain primitives, demystified.

Every idea in this repo leans on one of five web3 primitives. Each runs against Robinhood Chain Testnet (an Arbitrum L2, chainId 46630, native ETH gas, free on testnet). Contracts verify on Blockscout — no Etherscan API key required. What makes Robinhood Chain unique: tokenized real-world stocks live onchain as first-class ERC-20s, unlocking a whole primitive of its own.

The four secrets

Real-world stocks, onchain.

Robinhood Chain hosts canonical ERC-20 wrappers for major US equities. The stock-token primitive reads a user's balance to gate or personalize creative features.
