BlinkBounties

Antigravity

Inspiration

For small creators, the current system is brutal. You spend months creating something rare and valuable, list it on a marketplace, and compete against thousands of others with zero guaranteed outcome and a platform taking a cut regardless. Blink Bounties puts the power back in the creator's hands.

Existing raffle and ticketing platforms are slow, expensive, and opaque. Stripe takes days to settle. Platforms take 20% cuts. And there's no way to verify the winner wasn't chosen by the platform itself.

We saw an opportunity to rebuild this from scratch using Solana's core strengths: instant settlement, near-zero transaction costs, and trustless smart contracts to create something that's genuinely fairer and faster than anything built on traditional rails.

Who it's for:

Digital artists and collectors looking for fairer distribution
Communities priced out of traditional auction and raffle platforms
Global users who can't access card-based payment rails
Anyone tired of platforms taking 20% of every transaction

Why it matters: Existing platforms charge fees that make micro-transactions completely unviable. A $2 Ethereum gas fee destroys a $5 ticket sale. Solana's $0.00025 transaction cost changes the math entirely and opens up entirely new creator economies.

What it does

Blink Bounties is a high-frequency raffle marketplace powered by Solana. Creators list any digital item with a ticket price and supply. Buyers race to purchase tickets in real time with sometimes dozens of transactions per minute.

The moment the last ticket sells, the smart contract automatically selects a winner and settles the entire transaction on-chain, atomically, in under a second. No human approval. No platform custody. No waiting. The whole lifecycle runs at Solana speed.

How we built it

Smart contract built with Anchor (Rust) on Solana Devnet - handles escrow, high-frequency ticket issuance, and trustless atomic payout
Frontend built with Next.js and React using @solana/wallet-adapter
Solana Actions & Blinks (@solana/actions) - generates embeddable links so anyone can buy a ticket directly from X, Discord, or anywhere a URL lives, without ever visiting the site
Google Antigravity as one of our primary IDE's for writing and debugging code, particularly invaluable for navigating Solana-specific patterns like PDAs and account constraints in Rust
Deployed on Vercel

Challenges we ran into 🙈

Getting Anchor's escrow logic right for atomic settlement was brutal - one wrong account constraint and the whole transaction reverts
Solana's account model is nothing like EVM; PDAs and rent-exempt balances took real time to internalize
Blinks tooling is still maturing - sparse docs meant a lot of trial and error against the Dialect inspector

Accomplishments that we're proud of 🙊

Fully trustless settlement - the smart contract is the only authority, nobody can manipulate the outcome
Built by a 2-person backend team with zero prior Solana experience, shipped in under 24 hours
Blink links that embed the entire purchase flow anywhere a URL can go - no app download, no redirect

What we learned 🙉

Solana's speed isn't a marketing stat - 400ms finality fundamentally changes what consumer products are possible
Small contract surface area is everything when shipping fast under a deadline
Blinks are an underutilized primitive that could power an entirely new category of embedded commerce

We were surprised by:

How fast Solana settles even under load
How much friction a single redirect adds to a purchase flow
How little code you need to build something genuinely trustless

What's next for Blink Bounties

Switchboard VRF - provably fair, verifiable on-chain randomness for winner selection
Creator royalties - baked into the settlement contract so original creators earn on every raffle automatically
Mobile-first UX with gasless onboarding so anyone with a phone can participate without understanding crypto
Cross-platform Blinks - one link, any community, instant entry from X, Discord, Telegram, anywhere

Impact Metrics

Potential users:

$1.5 trillion global freelance and creator economy
Platforms currently extract 20%+ on every transaction from creators
Solana processes transactions at $0.00025 vs Ethereum's average of $2-50 - a 10,000x cost difference that makes micro-ticketing viable for the first time
