Public integration surface · chain 4663 · Robinhood Chain

Developers

MobbinHood.fun exposes a read-only, non-custodial integration surface for wallets, terminals, bots, and screeners. All data is sourced from canonical on-chain indexing of chain 4663. There are no private endpoints, authenticated feeds, or off-chain "score" reordering.

Verified HoodLaunchFactory

Chain ID4663

RoleHoodLaunchFactory

Address0x390a6d80f750cbddd3bd3815bf5cc5fa81a448ee

ABI referencesrc/abis/HoodLaunchFactory.json

Deployment block10115883

Source: contract_registry.verified = true. Do not use unverified addresses.

TokenCreated event

The verified factory emits TokenCreated on every new launch. Committed ABI: src/abis/HoodLaunchFactory.json.

Solidity signature

event TokenCreated(
  address indexed token,
  address indexed creator,
  bytes32 indexed salt,
  uint256 timestamp
)

Topic0 (keccak256 of the canonical signature)

keccak256("TokenCreated(address,address,bytes32,uint256)")

Fields

token (address, indexed) — the newly deployed ERC-20 launch contract
creator (address, indexed) — deployer / owner that initiated the launch
salt (bytes32, indexed) — CREATE2 salt used for deterministic deployment
timestamp (uint256) — block timestamp of the launch

Launch feed API

GET https://mobbinhood.fun/api/public/launches returns paginated canonical launches for chain 4663. Cursor-based; no offsets.

limit — 1..100, default 25
cursor — opaque base64url token returned as nextCursor
Order is launched_at DESC, address ASC — stable and deterministic
Rate limit: 60 req/min per instance. On excess returns 429.
Cached for 15s at the edge. Freshness fields report indexed block, reconciliation lag, and stale/degraded state.

curl "https://mobbinhood.fun/api/public/launches?limit=25"

curl "https://mobbinhood.fun/api/public/launches?limit=25&cursor=<nextCursor>"

Every EVM integer quantity (price, FDV, volume) is a decimal-string in native wei. Never parse as JS Number — use BigInt. Null means "no canonical data yet", never zero.

Freshness & reconciliation

indexedBlock is the last block observed by the canonical indexer.
reconciledAt is the last successful reconciliation timestamp.
stale = true when reconciliation is older than 10 minutes.
degraded = true when block-lag exceeds indexer thresholds.

Integration recipes

Wallets: index TokenCreated from the verified factory address for canonical launch discovery. Poll the launch feed for cross-checked market metrics.
Terminals: fetch /api/public/launches every 15s; page with nextCursor. Render decimal-string quantities via a BigInt formatter.
Bots: subscribe to on-chain TokenCreated from the verified factory. Do not depend on this feed for latency-sensitive execution.
Screeners: use canonical FDV / ATH FDV / volume exactly as returned. Do not derive prices from Number() casts.

All integrations are read-only and non-custodial. There are no API keys, no OAuth, no wallet actions from this surface.
