2% of each withdrawal goes to the Claimr treasury. This is enforced by the smart contract.
Example: Withdraw 1 SOL → receive 0.98 SOL.
Minimum Withdrawal
0.04 SOL. Withdrawals below this threshold are rejected.
Collection
Collecting fees from the Pump.fun vault to the PDA is free for callers. Claimr covers the transaction fee.
Rent
Solana accounts require ~0.00089 SOL to remain rent-exempt. For partial withdrawals, at least this amount must remain in the PDA. The contract enforces this to prevent account closure.
