Launch notes: the rail, the lock, block one

Robinhood Chain went to mainnet on 2026-07-01 — an Ethereum L2 on the Arbitrum Orbit stack, chain id 4663, ETH for gas, contracts deployable by anyone. It was built for tokenized stocks; its first passengers were memecoins. The desk is neither: it's a treasury product that happens to enjoy the block times.

The launch used the chain's standard rail (live since 2026-08-05), which settles every launch into a Uniswap v4 pool with permanently locked liquidity. "LP locked forever" is therefore not a team promise you have to trust — it's a property of the rail. The 2021 cohort's most common exit, draining the pool, is structurally closed; that class of rug accounted for a documented share of the roughly 45% of LP-lock promises that were broken industry-wide.

From block one, the floor dashboard has marked backing per token on-chain: the tribute flowing in, the stream flowing out, every redemption receipted in the house ledger. The Terminal reads the same books this site does. Verify the contract address independently — always, everywhere — and never risk money you cannot afford to lose.
