No custody
Transactions are built in your browser and signed by your wallet. Evenrain's server only reads public chain data and stores the receipt. It never holds tokens, keys or seed phrases.
Fair airdrops · Solana · no custody
Every wallet gets the same drop.
Build a recipient list, strip out obvious bots, preview exactly what it costs, then send SPL tokens straight from your own wallet in batches. Each drop gets a public receipt with every transaction signature.

1 · Pick a token you hold
Connect a wallet to list its SPL tokens.No wallet connected yet. Evenrain supports Phantom, Solflare and Backpack. Nothing is signed until step 5.
2 · Build the recipient list
Your own wallet is always left out.Holders are read on-chain with getProgramAccounts on the token program filtered by mint, then merged per owner and sorted by balance. Large tokens (hundreds of thousands of accounts) can take up to a minute. The list is capped at the number you choose and we say when it was cut.
3 · Anti-bot filters
Optional. Checked on-chain by the server, cached for hours.Remove duplicates, invalid and off-curve addresses
alwaysAlways on. Off-curve addresses are program-derived (no private key): vaults and pools, not people.
Filters reduce bots; they can't catch every sybil. A patient farmer with aged, funded wallets will pass. Treat this as a cleanup, not a guarantee.
4 · Shares
Tiers follow list order (holder lists are sorted largest first). Each tier gets a weight; the total is split by weight. Wallets past the last tier get the last tier's weight.

How Evenrain works, and what it can't do
You pay the fees
Each transaction costs a base fee of 0.000005 SOL plus your chosen priority fee. Recipients without a token account need one created, which locks a small rent deposit (the live amount, currently about 0.0015 SOL, is shown in the preview). You pay it; the account belongs to the recipient.
Filters are a sieve, not a wall
Age, activity, balance and funder checks remove the cheapest bots. Determined sybil farms with aged, funded wallets will still get through. Every removal is listed with its reason.
Sending is batched
Several recipients share one transaction (create-account-if-missing + transferChecked), packed to Solana's 1,232-byte limit. Failed or expired transactions can be retried; nothing is retried until it has definitely expired.
Public receipt
Every drop gets a page with the token, the filters used, the recipient list and each transaction signature. The server checks each signature on-chain and that it was paid by the sender.
Not supported
Token-2022 mints with transfer hooks, non-transferable, confidential or default-frozen extensions. Transfer-fee mints work, but recipients receive the amount minus the mint's fee.
