Request type

Blockchain integration (+ DEX/launchpad attribution on it)

Blockchain

• Name: Robinhood Chain
• Chain ID: 4663 (EVM, Arbitrum Orbit L2, native ETH, settles to Ethereum)
• Status: mainnet live, registered on chainlist (chainid.network entry robinhoodchain)
• Public RPC: https://rpc.mainnet.chain.robinhood.com
• Explorers: https://robinscan.io · https://robinhoodchain.blockscout.com (Blockscout, EIP-3091, full API)
• Docs: https://docs.robinhood.com/chain
• Bridge: canonical Arbitrum portal bridge (https://portal.arbitrum.io/bridge)

The chain already has significant activity: DefiLlama tracks it with >$250M TVL (chain page), and it is already indexed by DexScreener (robinhood) and GeckoTerminal (robinhood) with active venues including Uniswap v2/v3/v4, PancakeSwap, SushiSwap, and several launchpads (Clanker, Bankr, Virtuals, EasyA…).

DEX / launchpad we represent: Diggers

• App: https://diggers.fun · X: https://x.com/diggersdotfun
• What it is: fair-launch token launchpad built natively on Uniswap V4. One singleton contract is factory + swap router + the only LP of every pool: each launch seeds the full 1B supply as permanently locked single-sided liquidity in a hookless V4 pool (ETH is currency0) — no bonding curve, no migration step, liquidity can never be removed.
• Main contract (source-verified): 0x4190a197e9c7c8D9ce1095c32e6666A13A996580 — https://robinhoodchain.blockscout.com/address/0x4190a197e9c7c8D9ce1095c32e6666A13A996580
• Open-source contracts: https://github.com/DIGGERSdotFUN/diggersV1
• Indexer-friendly events: every pool leg emits a rich Swapped event (post-trade sqrtPrice/tick/liquidity + ETH/token reserves), plus Created, Harvested, and holder/volume telemetry events — everything needed to chart pairs without archive tracing.

Offer: we can implement your Integration SDK

We are happy to implement the DEXTools HTTP adapter API (/latest-block, /block, /events, etc.) for Diggers — or for Robinhood Chain generally via the Blockscout backend — if that accelerates the integration. Tell us which path you prefer and we'll build against the OpenAPI spec.
