memba_market_config package

Overview

Admin operations — DAO-gated, with a 2-step admin handoff and a hard fee ceiling. There is intentionally NO Pause() here (see config.gno SAFETY note): pausing the fee spine would brick every engine at once. Per-engine Pause() is the kill switch.

Package memba_market_config is the DAO-owned fee spine for the Memba marketplace. It is the single source of truth for the per-lane protocol fee (basis points) and the treasury that receives it. Every trade engine (NFT, services, token-OTC, agents) reads GetFeeBPS(lane) + GetTreasury() at settlement, so the DAO sets the rate ONCE and it applies everywhere — that shared read is what makes the lanes one marketplace.

SAFETY (panel finding C1): the read getters are PURE and NON-FAILING — they never panic, and there is intentionally NO Pause(). A per-trade cross-realm read that could fail or halt would be a single point of failure able to brick every engine at once; instead an engine always gets a usable, bounded value here and clamps locally, while each engine keeps its OWN Pause() as the real kill switch. The fee is bounded to [0, MaxFeeBPS] on write, so a reader can trust the bound without re-checking.

Render — public read-only view + audit surface for the fee config.

Functions

AcceptAdmin

func AcceptAdmin(cur realm)

AcceptAdmin completes the handoff. Only the pending admin can call it.

GetFeeBPS

func GetFeeBPS(lane string) int

GetFeeBPS returns the protocol fee in basis points for a lane. An unset or unknown lane returns DefaultFeeBPS. The result is always within [0, MaxFeeBPS] (enforced on write). Never panics — an engine must always be able to settle.

Param

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/samcrew/memba_market_config.GetFeeBPS()"

Result

Render

func Render(path string) string

Param

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/samcrew/memba_market_config.Render()"

Result

SetFeeBPS

func SetFeeBPS(cur realm, lane string, bps int64)

SetFeeBPS sets a lane's protocol fee in basis points, clamped to [0, MaxFeeBPS]. A value above the 5% ceiling is rejected so a misconfiguration can never overcharge.

TransferAdmin

func TransferAdmin(cur realm, newAdmin address)

TransferAdmin proposes a new admin (the memba_dao executor). The 2-step handoff requires the new admin to AcceptAdmin, so a transfer to a wrong or uncontrolled address cannot lock the realm.
