Platform Infrastructure
Robinhood user transactions and Base randomness integration
Platform Infrastructure
Networks
User-facing FOSNFT, Processor, Referral, and Verify interactions belong on Robinhood Chain, not Base. Base serves the specified VRF randomness integration, with CCIP transporting cycle requests and results.
| Network | Chain ID | Native currency | Role |
|---|---|---|---|
| Robinhood Chain | 4663 | ETH | User-facing project network |
| Robinhood Chain Testnet | 46630 | Test ETH | Separate testing network |
| Base | Environment-specific | ETH | VRF service side of the specified cross-chain design |
The Robinhood IDs, currency, and URLs below are corroborated by the public ethereum-lists network registry, with a separate testnet entry. This corroborates network metadata; it does not verify FOS deployments or CCIP support.
- Mainnet RPC listed in the registry:
https://rpc.mainnet.chain.robinhood.com - Mainnet explorer listed in the registry: Robinhood Chain Blockscout
- Testnet RPC:
https://rpc.testnet.chain.robinhood.com/rpc - Testnet explorer: Robinhood testnet explorer
- Official documentation linked by the registry: Robinhood Chain documentation
Verify the selected environment and live RPC chain ID before signing. Never reuse Base or Base Sepolia addresses for a Robinhood transaction. The Base environment used by the VRF integration must be confirmed separately.
ETH pricing and gas
The displayed dollar values are nominal product labels. On-chain ETH prices and cycle settings are the transaction source of truth. Ordinary mints require the exact configured price; free positions require zero purchase value. Network gas still applies. ETH remains volatile, and neither fixed gas costs nor USD-equivalent awards are guaranteed.
Wallet access
Use an EVM wallet configured for the correct Robinhood network. MetaMask and Coinbase Wallet are documented integration targets; connector behavior must be verified in the deployed main application. This Next.js repository hosts documentation and an AI assistant, not the minting application itself.
The interface does not need a user's private key. Contracts nevertheless hold cycle funds, reserved free-position contributions, and deferred payments according to their rules. An interface described as non-custodial does not mean that funds never enter a contract.
Cross-chain visibility
Show Robinhood cycle status and transaction receipts separately from Base VRF and CCIP delivery status. A successful last-mint receipt is not evidence that the remote random result has arrived or that the allocation transaction has completed.
