Documentation

Everything you need to launch, trade, and build on RobinPad.

Overview

RobinPad is a decentralized token launchpad built on Robinhood Chain — an Ethereum L2 on the Arbitrum Orbit stack (mainnet chain ID 4663, testnet 46630). Anyone can deploy an ERC-20 token in a single transaction, with liquidity seeded automatically and trading live within seconds.

One-transaction launch

Deploy ERC-20 + bonding curve + LP lock atomically.

Real-time

Sub-second price, trade, and reply updates.

No rug

Liquidity permanently locked on launch.

How it works

Launching a token on RobinPad takes one transaction:

  1. 1

    Deploy ERC-20

    A new ERC-20 contract with your name, ticker, 1B fixed supply, and IPFS metadata.

  2. 2

    Create bonding curve

    A bonding curve market is created — price rises with each buy, falls with each sell.

  3. 3

    Seed liquidity

    Initial single-sided liquidity gives the token an instant market.

  4. 4

    Lock LP permanently

    The LP NFT is sent to a locker with no withdraw function — liquidity is permanent.

Graduation. When the bonding curve reaches the threshold, liquidity migrates to a full Uniswap V3 pool. The token "graduates" to open-market trading — just like pump.fun tokens graduate to Raydium.

Anti-snipe. Robinhood Chain uses first-come-first-served sequencing. Creators can buy in the launch block to protect against sniper bots front-running the pool.

Gas-free disclaimer: Robinhood's gas-free promotions may apply only to Robinhood's own products — not guaranteed for third-party dApps. Confirm with the chain team (chain-developers-group@robinhood.com). For Web2-grade UX, consider ERC-4337 paymaster sponsorship.

Liquidity & pricing model

RobinPad uses a bonding curve for initial price discovery, then migrates to single-sided Uniswap V3 on graduation. Pump.fun's exact curve is Solana-specific; our curve is redesigned for Solidity while preserving the same user experience: price rises as people buy, falls as they sell.

Advantages

  • • Deterministic, on-chain pricing
  • • Audited Uniswap V3 on graduation
  • • Familiar pump.fun-style UX
  • • Creator royalties on every trade

Trade-offs

  • • Curve params need tuning
  • • Graduation window exists
  • • LP management complexity

Security & audit

Security is non-negotiable before mainnet. This checklist is mandatory:

External audit of factory, bonding curve, and LP locker
Foundry test suite with full branch coverage
LP locker has no withdraw/unlock — verified in source + bytecode
Reentrancy guards on all state-mutating functions
Creator royalty vault uses timelock, not admin keys
Rate limiting on create-token endpoint
Image moderation before public uploads
Full testnet soak test before mainnet

Wallets & bridging

RobinPad supports all standard EVM wallets via JSON-RPC:

MetaMaskRabbyOKX WalletWalletConnect v2

To onboard ETH from other chains:

  • Canonical Arbitrum Bridge — official, ~7 day withdrawal challenge period.
  • Relay / Across — fast bridge for quick onboarding.

Deployment guide

1

Local & testnet

done

Deploy to testnet (46630). Verify create → trade → graduate → claim flows end-to-end.

2

Audit

in-progress

Submit factory, bonding curve, and LP locker for external audit. Remediate all findings.

3

Mainnet deploy

pending

Deploy audited contracts to mainnet (4663). Verify on Blockscout. Seed parameters.

4

Launch & monitor

pending

Open to public. Monitor indexer health, gas, bot activity. Keep kill-switch ready.

Frequently asked questions

Is this financial advice?

No. Nothing on RobinPad is financial advice. Tokens are volatile and you may lose 100%.

Can liquidity be rug-pulled?

No. The LP NFT is locked in a contract with no withdraw function at launch.

How fast is real-time?

The indexer subscribes to on-chain logs via WebSocket, not polling. Updates reach your browser in hundreds of milliseconds.

What happens at graduation?

When the bonding curve fills, liquidity migrates to a full Uniswap V3 pool for open-market trading.

Do I need ETH for gas?

Currently yes. ERC-4337 gas sponsorship is planned so users can launch without holding ETH.
