Wasm cost table

Fields

regular: u32

Default opcode cost

div: u32

Div operations multiplier.

mul: u32

Div operations multiplier.

mem: u32

Memory (load/store) operations multiplier.

static_u256: u32

General static query of U256 value from env-info

static_address: u32

General static query of Address value from env-info

initial_mem: u32

Memory stipend. Amount of free memory (in 64kb pages) each contract can use for stack.

grow_mem: u32

Grow memory cost, per page (64kb)

memcpy: u32

Memory copy cost, per byte

max_stack_height: u32

Max stack height (native WebAssembly stack limiter)

opcodes_mul: u32

Cost of wasm opcode is calculated as TABLE_ENTRY_COST * opcodes_mul / opcodes_div

opcodes_div: u32

Cost of wasm opcode is calculated as TABLE_ENTRY_COST * opcodes_mul / opcodes_div

have_create2: bool

Whether create2 extern function is activated.

have_gasleft: bool

Whether gasleft extern function is activated.
