Your Keys.
Your Tokens.
AirdropSender.com is built on a strict non-custodial model. We have no access to your funds, no ability to move your tokens, and no server that stores your wallet data.
Architecture
Security Principles
We never see your private keys
AirdropSender.com does not have access to your private keys, seed phrases, or wallet credentials — at any point, ever. All signing happens locally in your wallet extension (Phantom, Solflare, etc.).
Non-custodial by design
Your tokens stay in your wallet until the moment they're distributed. We don't hold, escrow, or proxy your funds. Every transaction is signed and broadcast directly from your wallet.
No backend storage of wallet data
We do not store wallet addresses, token balances, or recipient lists on our servers. Your distribution data lives in your browser session only.
Direct on-chain execution
Distribution transactions are constructed client-side and submitted directly to the Solana (or other) network via your wallet provider. No intermediary server processes your transactions.
Vercel-hosted infrastructure
AirdropSender.com runs on Vercel's edge infrastructure with automatic DDoS protection, SSL/TLS everywhere, and no persistent server that can be compromised to access user funds.
Smart contract risk disclosure
Blockchain transactions are irreversible. Always verify recipient addresses and token amounts before signing. We cannot reverse or recover a completed distribution.
Transaction flow
How a distribution works
You configure the distribution
Recipient list, token, and amounts are set in your browser. Nothing is sent to our servers.
Transactions are built client-side
AirdropSender.com constructs the batch transactions locally. Your private key is never involved at this stage.
Your wallet signs
Phantom or Solflare prompts you to review and sign each batch. You see exactly what you're authorizing.
Broadcast to blockchain
The signed transactions are sent directly to the Solana network. AirdropSender.com monitors confirmation status in real-time.
Best practices
Stay safe when distributing
- Use a dedicated distribution wallet — not your primary treasury
- Double-check recipient CSV files before uploading
- Verify the token address in the app matches your intended token
- Never share your seed phrase or private key with anyone, including us
- Keep your wallet extension (Phantom / Solflare) up to date
- Use a hardware wallet (Ledger) for large distributions
- Review the full fee breakdown on the confirmation screen before signing
