TUBELINE One line into Robinhood Chain.

Stock Tokens trade on Robinhood Chain around the clock, long after the exchanges close. Tubeline brings your money in from eight chains: sign 5,000 USDC on Base for NVDA, and competing couriers (solvers) race to deliver it. Your price or better, or the order expires and Tubeline charges nothing.

See the SDK How it works

A capsule’s journey

  1. Post

    You sign an intent: what you want, not how, and the least you’ll accept. Sealed in its capsule, it reaches couriers privately, never a public mempool.

  2. Race

    Couriers, the network’s solvers, bid to fill it. The best price wins, and your minimum is the floor.

  3. Deliver

    The winner delivers on Robinhood Chain in a single block, and is repaid on your source chain only once the delivery is proven.

The race clock

The brass hand times the delivery alone: once a courier fills your order, it lands in one Robinhood Chain block, 100 ms. How long the fill takes depends on your source chain. The small hand is the canonical deposit from Ethereum, which takes minutes.

The vault

MEV protection: every order stays sealed until it is filled.

  • Returned if left unfilled
  • Sealed until filled
  • Proven before any payout

The telegraph room

One SDK, three lines of code. Orders are signed as EIP-712 typed data, in the shape of ERC-7683 cross-chain intents, with your minimum in the signature.

import { Tubeline } from '@tubeline/sdk'
const tube = new Tubeline({ key: TUBELINE_KEY, slippage: '0.5%' })
await tube.settle('5000 USDC@base', 'NVDA@robinhood', { minOut: '26 NVDA' })

The city of chains

Each district is a source chain: eight at launch, every line running straight to Robinhood Chain at the centre.

Choose a district to trace its line in.

Night shift

Exchanges close for the night. Robinhood Chain doesn’t, and neither will the hall.
