About

Projects use SealDraw to host giveaways, whitelists and airdrop raffles on Solana. Entering is always free: your wallet signs a short message, with no transaction. When entries close the list is frozen and hashed, and a future Solana block decides the winners together with a seed that was committed before entries opened. Every draw publishes its proof, so anyone can re-run it in the browser or with a standalone script.

Features

  • One Seeker Genesis Token, one entry — bots and wallet farms can’t stack entries
  • Three raffle types: Seeker-only, open to any wallet with a holding condition, or a holders snapshot with tickets by holdings
  • Token, NFT-collection and SOL holding conditions, checked at entry and again at closing
  • Seed committed up front; the winners are set by a future Solana block
  • A public proof for every raffle, with an in-browser re-run and a dependency-free Node.js checker
  • Raffle details locked once open; cancellations and late draws are shown publicly
  • Free to enter, always

Who it’s for

Hosts: Solana and Seeker projects running giveaways, whitelists or airdrops. Entrants: Seeker owners, or any Solana wallet for open raffles; holders-snapshot raffles need no action at all.

Sign-in

Sign In With Solana with Phantom, Solflare or Backpack — as a desktop extension, or in the wallet app’s browser on a phone. No e-mail, no password.

Price

Entrants pay nothing. Hosts: one free giveaway per Seeker per month until 31 January 2027 (up to 200 entries, created from a Seeker), or the Standard plan at US$14.99 per giveaway — unlimited entries, all raffle types and conditions — paid on-chain in USDC, SOL or SKR (20% off with SKR). Prizes are delivered by the host; SealDraw never holds them.

Data & privacy

  • Your account is your wallet address — no e-mail, password or name, and never your private keys.
  • Entries are public: every entry list, signed message and signature is published so anyone can check the draw.
  • SealDraw reads public Solana data: Seeker Genesis Tokens, the holdings a host asks for, and fee payments.
  • No third-party analytics, ad IDs or cookies; visits are counted anonymously without storing IP addresses.
