Fee Economics

FreezeDry uses a two-step payment model: TX cost reimbursement (guaranteed to the writer) plus a margin split by basis points.

Escrow Formula

escrow = max(min_escrow, chunks × 7,500 lamports)

• min_escrow: 15,385,000 lamports (~$2 USD floor)

• Rate: 7,500 lamports/chunk (5,000 TX reimbursement + 2,500 margin)

Two-Step Payment Split

On job completion, escrow is split in two steps:

Step 1 — TX Reimbursement (pass-through)

reimbursement = chunks × base_tx_fee (5,000 lamports)

Paid entirely to the writer. Covers actual Solana TX costs. Non-negotiable.

Step 2 — Margin Split (by BPS)

margin = escrow - reimbursement

Split by basis points locked at job creation:

Recipient	BPS	%	Per-chunk (at 7,500/chunk)
Writer	4,000	40%	1,000 lamports
Attester	1,000	10%	250 lamports
Treasury	3,000	30%	750 lamports
Referral	2,000	20%	500 lamports

No referrer → referral share redirects to treasury.

Writer total: 6,000 lamports/chunk (5,000 reimburse + 1,000 margin).

Cost Examples

File Size	Chunks	Escrow (SOL)	Cost @$130/SOL
500 KB	876	0.015	$2.00 (min floor)
1 MB	1,793	0.013	$1.75
5 MB	8,962	0.067	$8.73
10 MB	17,924	0.134	$17.46
15 MB	26,886	0.202	$26.19

Direct Inscription (No Marketplace)

If you inscribe directly (send memo TXs yourself), there is no escrow and no fee split. You pay only Solana network fees: ~5,000 lamports per memo transaction. This is roughly 43% cheaper than marketplace pricing.

The Jobs marketplace is for platforms processing at scale where dedicated node operators handle the volume. Direct inscription is for anyone who wants to run their own node or use the standalone tool.

Key Design Decisions

• Fee BPS snapshot: Locked at job creation. Authority cannot change splits mid-flight.

• Escrow floor enforced on-chain: Program rejects jobs where escrow <= chunks × base_tx_fee.

• Self-referral blocked: Creator cannot set themselves as referrer.

• Writer always gets reimbursed: TX costs come off the top before any split.
