claimy (CLI)

Command-line tool for running a Solana SPL / Token-2022 airdrop end-to-end: snapshot holders, weight allocations, build a Jupiter-compatible merkle tree, verify proofs.

Part of the claimy toolkit. See the repo for the SDK (@claimy/sdk) and the React widget (@claimy/widget).

Install

# global
npm install -g claimy

# or one-shot
npx claimy --help

Environment

All commands that touch the chain accept --rpc. If not passed, the CLI reads SOLANA_RPC_URL or HELIUS_RPC_URL from the environment.

export SOLANA_RPC_URL="https://your-rpc-provider/…"

The CLI never reads or writes a private key. If a command needs one, it's the wrong CLI.

Commands

| Command | What it does | |---|---| | airdrop snapshot | Fetch every SPL holder of a mint, write holders.csv | | airdrop weight | Apply a weighting strategy (linear / sqrt / tiered / uniform) | | airdrop tree | Build a Jupiter-compatible merkle tree → proofs.json + root.txt | | airdrop stats | Summary of a proofs file (root, claimants, totals) | | airdrop verify | Verify an owner's proof against the recorded root (local, no chain) | | airdrop format | Minify / pretty-print proofs.json for hosting |

End-to-end example

# 1. snapshot every holder of a source mint
airdrop snapshot \
  --mint 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU \
  --exclude-cex \
  -o holders.csv

# 2. weight the holders (sqrt = anti-whale)
airdrop weight \
  --input holders.csv \
  --mode sqrt \
  --total 1000000000000 \
  --output allocations.csv

# 3. build a merkle tree for YOUR airdrop mint
airdrop tree \
  --input allocations.csv \
  --mint <YOUR_AIRDROP_MINT> \
  --decimals 6

# 4. sanity check
airdrop stats -i proofs.json
airdrop verify -i proofs.json --owner <SAMPLE_WALLET>

# 5. deploy a Jupiter merkle-distributor with root.txt
#    (lock.jup.ag UI works today; `airdrop deploy` lands in v0.4)

# 6. host proofs.json on any static CDN, ship the claim page

Leaf format

Leaves are:

keccak256( index_le_u64 || owner_pubkey_32 || amount_le_u64 )

Matches the Jupiter merkle-distributor convention exactly — so proofs produced here verify against any Jupiter distributor without modification. Full details in docs/tree-format.md.

Exit codes

• 0 success
• 1 user error (missing flag, bad file, no RPC configured)
• 2 network / RPC error
• 3 on-chain / verification mismatch (verify command only)
