Robinhood Chain developer API

👨‍💻 Create Robinhood coins with API

Build an unsigned Direct V3 launch transaction, let the creator sign it in their own wallet, then verify the confirmed receipt and safely create the Launchpad token page. The optional first buy is a real atomic Uniswap V3 swap.

Your Robinhood API key

Connect your wallet and your Robinhood API key is created automatically and shown here ready to copy.

Connect wallet to generate your Robinhood API key.

The secret is stored only in this browser and shown by the server once.

Launch flow

1. BuildRequest canonical unsigned calldata.

2. SignCreator sends it with a Robinhood Chain wallet.

3. VerifyBackend verifies receipt, LP lock and first-buy Swap, then persists.

Endpoints

GET /api/evm/robinhood/statusNetwork and readiness

POST /api/evm/robinhood/build-direct-v3-launchUnsigned launch transaction

POST /api/evm/robinhood/verify-direct-v3-launchReceipt verification and persistence

GET /api/evm/robinhood/creator-rewards?wallet=0x...Creator LP fees

POST /api/evm/robinhood/build-creator-rewards-claimUnsigned fee collection

Security model

Never send a private key or seed phrase.
The API never accepts a client-selected factory, router, pool or fee locker.
The wallet signs and broadcasts the transaction.
Persistence occurs only after accepted-factory receipt verification.
Browser integrations must send the current same-origin CSRF token.

Production API v1

API-key authenticated launch flow

Server integrations use a Bearer API key and an idempotency key. The creator signs a deterministic launch intent with personal_sign; Launchpad verifies the signer, builds the same unsigned transaction used by the web creator, and independently verifies the confirmed receipt before persistence.

POST /api/v1/robinhood/media/uploadUpload and host a validated token logo

POST /api/v1/robinhood/launches/intentPrepare the deterministic creator message

POST /api/v1/robinhood/launches/buildVerify signature and return unsigned calldata

POST /api/v1/robinhood/launches/confirmVerify receipt, LP lock and first buy, then persist

GET /api/v1/robinhood/launches/status?launch_id=rhl_...Read idempotent launch state

GET /api/v1/robinhood/tokens/{address}Canonical token data

GET /api/v1/robinhood/tokens/{address}/tradesRPC-indexed external swaps

GET /api/v1/robinhood/tokens/{address}/candlesCanonical Launchpad candles

Upload token logo

curl -sS -X POST https://launchpad.meme/api/v1/robinhood/media/upload \
  -H "Authorization: Bearer lp_live_YOUR_KEY" \
  -F "image=@./logo.png"

Use the returned image_url in the launch intent. If image, website, X, Telegram, or description are omitted, Launchpad applies safe platform defaults.

1. Prepare intent

curl -sS -X POST https://launchpad.meme/api/v1/robinhood/launches/intent \
  -H "Authorization: Bearer lp_live_YOUR_KEY" \
  -H "Idempotency-Key: my-launch-001" \
  -H "Content-Type: application/json" \
  -d '{
    "creator":"0xYourWallet",
    "name":"Example Coin",
    "symbol":"EXAMPLE",
    "description":"Created through the Robinhood API",
    "image_url":"https://example.com/logo.png",
    "first_buy_wei":"100000000000000",
    "slippage_bps":100
  }'

2. Sign and build

// Sign intent.message with the creator wallet.
const signature = await ethereum.request({
  method: 'personal_sign',
  params: [intent.intent.message, creator]
});

const build = await fetch('/api/v1/robinhood/launches/build', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer lp_live_YOUR_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    launch_id: intent.launch_id,
    intent_signature: signature
  })
}).then(r => r.json());

await ethereum.request({method:'wallet_switchEthereumChain', params:[{chainId:'0x1237'}]});
const txHash = await ethereum.request({method:'eth_sendTransaction', params:[build.transaction]});

3. Confirm

curl -sS -X POST https://launchpad.meme/api/v1/robinhood/launches/confirm \
  -H "Authorization: Bearer lp_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"launch_id":"rhl_...","tx_hash":"0x..."}'

PHP example

$headers = [
  'Authorization: Bearer ' . getenv('LAUNCHPAD_API_KEY'),
  'Idempotency-Key: my-launch-001',
  'Content-Type: application/json'
];
// POST the same JSON shown above, sign intent.message in the creator wallet,
// then submit build.transaction and confirm the resulting tx hash.

Scopes and safety

New keys receive robinhood:launch:build, robinhood:launch:confirm, robinhood:launch:read and robinhood:market:read. The API never accepts a client-supplied factory, router, pool, locker or arbitrary calldata. API keys are stored as SHA-256 hashes and the full secret is shown only once.
