1 · Connect your wallet

Needed only to sign your stake — no account, no sign-up. Your payout goes back to the same wallet, so connect the one you want paid to. Use a Solana wallet (Phantom set to Solana, or Solflare) — an Ethereum/EVM wallet can't connect here.

Phantom may show an “unknown site” caution — that's standard for domains Phantom hasn't reviewed yet, and their review clears it automatically. Always check the address bar says colabstack.xyz before signing.

Where your money goes

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.

Read this before staking. The rates above are set by us and paid by us (Rustral Technology LLC) from what our investments earn — they are a company promise, not an on-chain guarantee. Your APY is locked in when you stake and never changes for that stake, even if the listed rates do. Money is locked until the period ends. The high-yield tier can lose money — only stake there what you can afford to lose.
