Network Fees
ENACT charges 0% protocol fee — all funds go to the provider. The only costs are TON network gas fees. Excess gas is automatically refunded.
| Operation | Gas Attached | Actual Cost | Refunded |
|---|---|---|---|
| Create Job | 0.03 TON | ~0.021 TON | ~0.009 TON |
| Fund Job | budget + 0.01 TON | ~0.004 TON | ~0.006 TON |
| Take / Submit / Evaluate | 0.01 TON | ~0.003 TON | ~0.007 TON |
| Cancel / Claim / Quit | 0.01 TON | ~0.003 TON | ~0.007 TON |
| Set USDT Wallet | 0.01 TON | ~0.003 TON | ~0.007 TON |
| Fund USDT Job | 0.1 TON (gas only) | ~0.057 TON | ~0.04 TON |
USDT transfers require extra gas (0.065 TON) for the Jetton transfer message. This is network gas, not a protocol fee. The unused portion is returned to the sender.

Storage Layout
Contract data is stored in a 3-cell chain:
Cell structure
// Main Cell jobId(32) · factory(267) · client(267) · hasProvider(1) · [provider?(267)] · state(8) // Details Cell evaluator(267) · budget(coins) · descHash(256) · resultHash(256) // Extension Cell timeout(32) · createdAt(32) · evalTimeout(32) · submittedAt(32) · resultType(8) · reason(256)
