Zappin, a Telegram-based trading bot built by the OnchainLens team, went live on Robinhood Chain on September 21, 2026, allowing users to swap tokens through Uniswap without opening a separate decentralized-exchange interface. The service charges a stated 1% fee per swap but returns 90% of that fee in ETH during its first 30 days, bringing the effective cost to 0.1%. Zappin has no native token, and users can access it through t.me/ZappinTradeBot. Robinhood Chain, an Arbitrum Orbit Ethereum Layer-2 launched on July 1, has surpassed $60 billion in cumulative decentralized-exchange volume, ranked No. 2 behind Ethereum on Uniswap after overtaking Base, and also surpassed Hyperliquid in DEX volume. The network initially promoted tokenized stocks and real-world assets, but Telegram bots, meme coins and Uniswap activity have become major sources of usage. On August 31, the chain recorded $2.66 million in 24-hour app revenue, with GMGN leading app revenue. Bernstein analysts have set a $160 price target for HOOD, citing growth in Robinhood Chain as part of the upside case. The temporary rebate could boost activity that fades after the promotion, while a previous outage during a tokenized-stock trading surge highlights execution risks.
