Vibestarter is going multi-chain, and the first new chain is Robinhood Chain. The full contract suite is deployed and verified on mainnet, the platform now speaks more than one chain end to end, and internal raises are already running through the complete lifecycle. When third-party raises open on Vibestarter, Robinhood Chain is live from day one.

Base is not going anywhere. It's where Vibestarter launched, where $VIBES lives, and where raises keep running exactly as they do today. Robinhood Chain is additive: a second venue on the same rails.

Why Robinhood Chain

Every app funded on Vibestarter is a consumer app built by AI agents. Consumer apps need consumers — and the most interesting thing happening in crypto distribution right now is Robinhood putting a chain under a brokerage with tens of millions of funded accounts.

Robinhood Chain is an Arbitrum-stack L2 built for bringing real-world assets on-chain: tokenized equities, 24/7 markets, ~100ms blocks, ETH for gas, and Uniswap as its primary AMM from day one. When that audience starts moving on-chain, it arrives somewhere new — without years of accumulated DeFi habits, and looking for things to actually use.

That's our bet, stated plainly: vibecoded apps are the kind of thing a retail-native chain will want, and founders should be able to raise where their next users are showing up. We're not migrating to chase it, and we're not pretending it's proven — we're making the platform chain-agnostic so raises can happen wherever the audience is, starting with the two chains we believe in.

Same protocol, new chain

The funding mechanics on Robinhood Chain are byte-for-byte the ones running on Base:

• Time-released funding. 10% of a successful raise releases to the founder at finalization; the remaining escrow releases 15% monthly over six months. No milestone committees, no discretion.
• Challenge windows. Every tranche is preceded by a 72-hour window where backers holding sufficient supply can file an on-chain challenge.
• Permanent liquidity. 15% of raised ETH is paired into a liquidity pool at finalization and locked forever — the position sits in a contract with no withdraw or transfer path, so liquidity can never be pulled.

What actually changed under the hood

Multi-chain here is one platform, not parallel deployments. The pieces worth knowing about:

• Chain-scoped everything. Every raise carries its chain from launch — through the database, the indexer, the APIs, and every surface of the app. One deployment serves both chains; each chain's raises are isolated by that chain's own router contract.
• Liquidity on Uniswap v3. Robinhood Chain has no Aerodrome yet, so we built a new LP subsystem on Uniswap v3 — the chain's primary AMM from day one: the pool is created at the backer entry price −5%, and the position NFT is locked in a soulbound vault that can collect trading fees but can never withdraw, transfer, or unwind the position. Permanent means permanent, on both chains. And a note on alignment: on Base we're Aerodrome-native, and that partnership matters to us — if and when Aerodrome expands to Robinhood Chain, we'd expect new raises there to route their liquidity through it.
• Arbitrum-correct contracts. Robinhood Chain is Arbitrum-stack, which has different block-number semantics than the OP-stack — our escrows read the ArbSys precompile where it matters, so refund snapshots are exact. Launch and terms signatures bind to each chain's own EIP-712 domain.
• The full product, not a port. Live price data and charts, an in-app swap quoting straight from Uniswap's QuoterV2, per-chain block-explorer links, and a gas helper that routes you through the canonical bridge when your wallet needs ETH on Robinhood Chain.
• Honest risk disclosure. Robinhood Chain's trust model differs from Base's — it runs a single sequencer and protocol-level transaction filtering. Our Risk Disclosure now covers what that means for escrowed funds, chain by chain. If a risk exists, you'll read it from us first.

In the app, you'll know where you are at a glance: every raise wears its chain — Base blue or Robinhood neon — on the card, the raise page, the ticker, and the ledger, and founders pick their chain as the first decision of the launch flow.

Day one, both chains

Robinhood Chain isn't a phase-two roadmap item. It ships as a day-one feature of third-party raises: internal raises are running through the full lifecycle on Robinhood Chain mainnet right now — launch, funding, finalization, locked liquidity, claims, trading. Third-party raises open with our Luxembourg incorporation, and the moment they do, founders choose their chain — Base or Robinhood — as the first decision of the launch flow.
