CollabStack connects four kinds of people around real software: donors who back projects they believe in, developers who get paid to build, builders raising seed money, and investors earning a fixed return — with us, Rustral, personally vetting where invested money goes.
We grow together — for a better world.
Real software people are funding — back one in USDC or SOL from any wallet.
Two simple paths — no jargon, no account. Pick one and you're done in about a minute.
A Solana wallet (Phantom or Solflare). No account, no signup — it's only used to sign.
Pick a lock period. Longer lock = higher fixed rate. You see your exact payout before you confirm.
Rustral invests it and pays your stated rate. Track your stake any time on the Earn page.
When the lock ends, your principal plus the return comes back to your wallet.
Browse builders raising money to ship real software.
Open any wallet and scan. No account needed.
USDC or SOL goes straight to the builder. A gift to help them ship — not an investment.
Pick yourself — you'll see your three steps and one button. Nothing else to figure out.
Stake USDC with us for a fixed period at a fixed rate. We invest it in profitable projects we vet ourselves and pay you back with the return at unlock.
1 month, 6 months, or 1 year — each shows its fixed APY up front. There's also a clearly-marked high-yield option for risk money.
The wallet is needed only to sign the transfer — no account, no forms. Your rate is locked in the moment you stake.
Principal + return comes back to your wallet when the period ends. What we invested in is listed on the earn page the whole time.
Rates change as we partner with more profitable companies. Subscribe and we'll email you when a better APY or a new offer opens up.
