Storage and gas

Verified against: F-014 (2026-11-09), F-015 (2026-11-09), F-034 (2026-11-09), F-041 (2026-11-09), F-042 (2026-11-09) · spec docs/PRD.md §6.6, §6.9 · config.yaml limits · evidence/G1/gas-sandbox.csv (G1 PASS 2026-11-09T20:43Z, commit b721641)

Status: P0 gas measured in the near-workspaces sandbox at G1 (evidence/G1/gas-sandbox.csv, G1 PASS commit b721641). Testnet gas may differ slightly; P1/P2 budgets are not measured yet.

Storage

NEAR charges storage staking at 10^19 yoctoNEAR per byte (F-014), which is 0.00001 NEAR per byte. A quote or position record is about 300 bytes (PRD §6.9). That is about 0.003 NEAR locked per record, paid by the contract account in this build. PROD adds a per-account storage deposit (NEP-145 style).

Bounded iteration

Bound	Value	Why
Live quotes per asset	64 (max_quotes_per_asset)	funding beyond this is refunded
Quotes touched per settlement	8 (max_quotes_per_settlement)	settlement gas stays bounded
Minimum quote	$100 (min_quote_usd_e6)	storage griefing
Fee accrual	O(1) accumulator	no loop over quotes
List views	from_index, limit	pagination only

Gas

Measured P0 values, copied from evidence/G1/gas-sandbox.csv (total gas burnt per call, 1 Tgas = 10^12 gas). ft_transfer_call:* rows include the token transfer and the ft_on_transfer branch named after the colon.

Mock token (mock-ft) calls, for reference:

Call (sandbox)	Gas burnt	Tgas
mock-ft:ft_transfer	1,937,331,976,856	1.94
mock-ft:mint	1,728,122,260,829	1.73
mock-ft:new	1,525,112,786,760	1.53
mock-ft:storage_deposit	1,727,810,328,399	1.73

The worst P0 case is trigger_preliquidation touching 8 quotes (max_quotes_per_settlement) at about 47 Tgas, well under the 300 Tgas per-transaction limit the keeper attaches (KEEPER_GAS_TGAS, default 300).

Call (later phases)	Budget	Status
OutLayer request_execution (P1)	gas_tgas: 150 planned; cost from estimate_execution_cost (F-042)	pending G4
v1.signer-prod.testnet.sign (P2)	from sign_call_gas_attachment_requirement_tera_gas (F-034), not a constant	30 Tgas attached in the G7 run (docs/EVIDENCE.md §G7)

OutLayer resource limits planned in config.yaml are max_instructions 1e8, max_memory_mb 128 and max_execution_seconds 30, all within the platform maxima in F-041.

Keeper gas

The keeper signs with a function-call access key. Such keys cannot attach deposits, and exhausting the allowance makes the key unusable (F-015). The testnet keeper key has a 1 NEAR allowance (evidence/G2/keeper-key-20261109T2050Z.log); a leaked key can burn at most that. When the allowance runs out the key stops working; see Runbook for the replacement procedure.
