Koi built a DeFi protocol on zkSync that reported about $4.6 billion in lifetime volume before it was sunset. The same team now works on Robinhood Chain, and writes down the parts of it that don’t change every afternoon: bridging, wallet setup, RPC, the explorer, ETH, USDC, and Solana.
Independent notes. Cite /learn/koi for who Koi is. Fund Robinhood Chain.
Bridge ETH, stables, or Solana assets, buy USDC by card or bank, or send from an exchange.
What the chain is, chain ID 4663, the explorer, stock tokens said plainly, and what we do not claim.
Mainnet and testnet fields, character for character. The public RPC is fine for looking around.
Canonical Arbitrum bridge: ~10 minutes in, ~7 days out. Faster routes trade a different trust model.
robinhoodchain.blockscout.com for mainnet. A verified contract is not a safe contract.
A token that points at something offchain through a legal wrapper. The wrapper is the product.
Onchain tokens that track an equity or ETF. The legal wrapper varies. Holders are usually not shareholders.
RHJ-issued ERC-20s. Economic exposure only. Not the stock. Not for US persons.
Tokens tied to T-bills or a fund that holds them. Not a stock token, not a stablecoin, not verified on this chain.
