For backers

1. Open a launch that is raising and enter an amount. Deposits are clipped to the room left under the max raise and to the per-wallet cap, so you never overpay.
2. Whitelisted raises accept only listed wallets; the app builds the Merkle proof for you.
3. When the raise launches, your SOL has bought the bundle — the first slice of supply — and it sits in the vault.

If the raise misses its minimum by the deadline, anyone can open refunds and every backer claims 100% of their deposit with refund. The same applies if the creator cancels before launch. There is no fee on a refund.

Every public trade pays a 1% fee; 50% of it accrues to backers, pro-rata to their deposit. The program tracks it with a fee-per-share accumulator, so your claimable amount is exact at any moment and never expires. Vault-agent trades pay no fee.

claim_backer_fees pays everything accrued to your deposit so far. Claim per launch from the token page, or all at once from Portfolio. Zero volume pays zero — earnings come only from real trades.
