The launchpad for Aligned Coins on Robinhood. Each coin is deployed with built-in dynamic vesting, dividends, locking with non-inflationary rewards and protocol rewards for best performing coins of the day.
castr.fun is a token launchpad where the token works for the holder, not against them. Founders launch on a bonding curve, holders earn real yield from trading activity, and every protection other launchpads promise is enforced in the contracts instead. Currently live on Robinhood Chain Testnet.
Token launchpads have converged on one model - launch fast, extract early, abandon. Snipers buy the first block, insiders split allocations across wallets to mimic real holders, deployers dump into the graduation spike, and holders are left with a token that has no reason to exist the day after launch. The trust deficit isn't a marketing problem, but a structural, because nothing in the contracts prevent it.
That cuts both ways. Honest founders launching on these platforms inherit the same distrust as the bad actors, because buyers can't tell them apart. A founder who intends to build has no way to prove it, so every launch is priced as a likely rug.
The question behind the product is simple: what would a launchpad look like if the rules protecting holders were code, not promises?
An aligned coin is one where founders, early buyers, and long-term holders all win by the same behavior - holding.
For holders, holding pays continuously rather than only on exit. Every token distributes ETH dividends from trading fees, pro rata through a magnified-dividend accounting system. A launch window gate blocks trading in the opening blocks, removing atomic same-block sniping and bundling, so early buyers aren't just exit liquidity for bots and scammers. There are also dynamic sell locks on each buy for up to 24 hours (gets shorter with more liquidity) , giving confidence for later buyers that they won't be flipped from earlier holders.
For founders and deployers, castr.fun turns good intentions into a verifiable commitment. Each early holder allocation vests onchain proportionate to their share, under an enforced minimum floor. The deployer can optionally lock their holdings indefinetly untill graduation. A founder launching on castr.fun doesn't have to ask buyers for trust. The contracts show it.
At graduation, when the curve goal is reached, liquidity migrates automatically into a Uniswap V3 concentrated-liquidity pool. Then collected fees from it are distributed as dividends and rewards. Dividends are distributed to each holder proportionally to their share. Token rewards are distributed to holders who decided to lock their tokens for up to 1 year, or auto burn if no lockers exist. Locked positions are represented as NFTs whose artwork is generated entirely onchain as SVG, so every lock is visible, verifiable, and owned. The token deployer gets 20% of the token rewards, locked for 30 days.
The contract suite is written in Solidity with Foundry and OpenZeppelin: a bonding curve with launch-window protection, a dividend distributor, a vesting calculator, a liquidity migrator into Uniswap V3 concentrated liquidity, and NFTSVG, an onchain SVG generator for lock position cards. Automation of protocol rewards via Cloudflare cron job and The Graph. The frontend is Next.js on Cloudflare Workers with D1, KV, and Images, wallet connections through wagmi and Privy.
castr.fun has been audited by KannAudits
Applied the post-audit fixes (audit can be found at https://kannaudits.com/audits/castr-fun-token-launchpad-august-2026), added new features, updated event emits, added quality of life changes for Frontend usage and updated the implementations for Robinhood Chain. The test deployments on Robinhood Chain testnet have been tested (deployed implementation used 0.01 ETH bonding curve goal and other slight tweaks for test purposes, including testnet deployment of UniswapV3), updated the website to support Robinhood Chain and I also added USDG to the assets for the swap widget on the graduated tokens. Also updated the subgraph for the reward system, deployed it on goldsky (public endpoint can be found here) and made a custom automation for triggering the rewards, as Chainlink doesn't supprot Robinhood Chain testnet yet.
