Security

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

1

You configure the distribution

Recipient list, token, and amounts are set in your browser. Nothing is sent to our servers.

2

Transactions are built client-side

AirdropSender.com constructs the batch transactions locally. Your private key is never involved at this stage.

3

Your wallet signs

Phantom or Solflare prompts you to review and sign each batch. You see exactly what you're authorizing.

4

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
