padv2 source realm

Package pad is gnomemepad: a self-contained meme launchpad for gno.land.

Example

1CreateWithVenue (bond + venue-aware GNS escrow) -> GRC20 + WUGNOT curve -> Graduate
2  -> internal CPMM; then either:
3     gnoswap: RetryList / RetryListGnoswap (escrowed GNS + WUGNOT inventory)
4     zdex:    ReleaseListSeed -> EOA CreatePool -> ConfirmZdexList

Production: Buy/Sell/Swap* use WUGNOT (push-pay + prepaid credits). Payment: user wugnot.Transfer(pad, amount) then Buy. Create fee: gnoswap preference locks ListFeeGns; zdex preference locks 0. DefaultListVenue source = zdex; Pearl may SetDefaultListVenue(gnoswap) after deploy. Unit tests (testSkipBanker): OriginSend ugnot as collateral units. Tokens are real GRC20 (mint on buy, burn on sell).

1const (
2	VenueGnoswap = "gnoswap"
3	VenueZdex    = "zdex"
4)

source

ListVenue IDs (compile-time switch in tryListVenue). Adding a new DEX means a new case + adapter file and a new pad version — Gno cannot dynamically import by path string.

source

1func AdenaPathOf(id string) string

source

AdenaPathOf returns the grc20reg / Adena token key: packagePath.SYMBOL (Token.ID is packagePath.SYMBOL.seq - Adena rejects that form).

1func AdminInfo() string

source

AdminInfo is a single-line dashboard snapshot for the ops UI:

Example

1protocolAddr|pendingFees|paidFees|reservedUgnot|launchCount|pointsOn|inited|padAddr

pointsOn/inited are 0|1.

1func Allowance(id string, owner, spender address) int64

source

Allowance returns how many tokens `spender` may TransferFrom from `owner` (same GRC20 semantics as wugnot/gns.Allowance, keyed by launch id).

1func Approve(cur realm, id string, spender address, amount int64)

source

Approve sets GRC20 allowance so DEX/contracts can TransferFrom.

1func BalanceOf(id string, owner address) int64

source

1func Buy(cur realm, id string, amountWugnot, minTokensOut int64) int64

source

Buy spends WUGNOT on the bonding curve; credits tokens. amountWugnot: max to spend (may overpay). UI: Deposit + Transfer(pad, amt) + Buy. Overpay stays as claimable prepaid — ClaimWugnot anytime (incl. after list). minTokensOut: slippage floor (0 = disabled). Auto-graduates at threshold or sold-out.

Production: collateral is real WUGNOT on pad -> Graduate can auto-list Gnoswap. Tests (testSkipBanker): amountWugnot ignored; OriginSend ugnot is used as units.

Last-fill (no overshoot):

Cap net so RaisedUgnot never exceeds graduationThreshold() (refund excess WUGNOT).
Cap by remaining curve tokens (CurveSupply - RealSold).

If the curve is already sold out (or raise already filled), Buy refunds the full take and graduates when ready - no panic so users are not stuck mid-tx.

1func ClaimCreatorFees(cur realm, id string) int64

source

ClaimCreatorFees withdraws accrued creator fees for a launch. Only the token creator may claim. Fees stay on pad until claimed.

1func ClaimListFee(cur realm, id string) int64

source

ClaimListFee refunds Create-time GNS escrow to the token creator if still unlisted. Use when graduate/list will not complete or creator abandons listing.

1func ClaimProtocolFees(cur realm) int64

source

ClaimProtocolFees withdraws pending protocol fees to protocolAddr. Only the current protocol treasury key may call (same wallet that Init'd, unless TransferProtocol was used).

1func ClaimWugnot(cur realm) int64

source

ClaimWugnot withdraws all of the caller's prepaid WUGNOT credit to their wallet. Safe after Buy overpay or after graduate/list — excess stays claimable until claimed.

1func ConfirmZdexList(cur realm, id, poolId string)

source

ConfirmZdexList marks a launch listed on zdex after EOA CreatePool succeeded. poolId e.g. "ugnot|SYMBOL" (must be non-empty; no on-chain pool verify). Creator or protocol. Prefer ReleaseListSeed first when pad still holds LP seed.

1func Create(cur realm, name, symbol, uri string) string

source

Create deploys a fair-launch meme. Create bond (bond realm / fallback const) is a platform fee credited to protocol immediately (not refundable escrow). Also locks ListFeeGns free GNS when venue requires it (creator Transfer GNS first). No pre-mint; all tradeable float starts on the bonding curve.

1func CreateBondRequired() int64

source

CreateBondRequired is a public alias for UIs / qeval (same as requiredCreateBond).

1func CreateWithVenue(cur realm, name, symbol, uri, venueId string) string

source

CreateWithVenue is Create + PreferredVenue in one MsgCall (fee escrow follows venue). venueId: "zdex" → no GNS list escrow; "gnoswap" → ListFeeRequired GNS.

1func DefaultListVenue() string

source

DefaultListVenue returns the venue id used when callers pass "".

1func FeeInfo() string

source

FeeInfo returns protocolAddr|pendingUgnot|paidUgnot for UIs.

1func FreeGns() string

source

FreeGns returns free|have|reserved for UI preflight (GNS list fee).

1func FreeWugnot() string

source

FreeWugnot is free|have|reserved|totalCredit for UI preflight.

1func GRC20Bank(id string) *grc20.Token

source

GRC20Bank returns the underlying *grc20.Token for interop (metadata / external DEX). Does not expose PrivateLedger - mint/burn stay pad-only.

1func GetCreatorFees(id string) int64

source

1func GetPool(id string) (ugnot, token int64)

source

1func GetRaised(id string) int64

source

1func GetStatus(id string) int

source

1func GnoswapListedOf(id string) bool

source

1func GnoswapPoolPathOf(id string) string

source

GnoswapPoolPathOf returns the Gnoswap pool path after listing (or empty).

1func Graduate(cur realm, id string)

source

Graduate permissionlessly moves a ready curve into a permanently locked CPMM. Ready when RaisedUgnot >= graduationThreshold(), or when RealSold >= CurveSupply with RaisedUgnot > 0 (sold-out before threshold - escape hatch for unreachable raise).

1func GraduationThresholdLive() int64

source

GraduationThresholdLive returns the live raise target (ugnot) for UIs/qeval.

1func Init(cur realm)

source

Init sets the protocol treasury. First EOA caller becomes fee recipient (protocolAddr). Protocol trade fees accrue on-pad until ClaimProtocolFees (treasury only) or PushProtocolFees (anyone may push to treasury). Creator fees always need ClaimCreatorFees by the token creator.

Deploy note: call Init with the wallet that should receive protocol fees (or TransferProtocol later). Gnoswap CreatePool GNS fee is paid to Gnoswap, not to this treasury.

1func IsProtocol(addr string) bool

source

IsProtocol reports whether addr is the current treasury (for UI gating).

1func LaunchCount() int

source

1func LaunchInfo(id string) string

source

LaunchInfo returns a single-line pipe-delimited summary for UIs/indexers:

Example

1id|name|symbol|status|raised|sold|buyers|creatorFees|poolUgnot|poolToken|uri|creator|virtualUgnot|virtualToken|created|tokenID|gnoswapReady|gnoswapListed|gnoswapPoolPath|gnoswapNote|listVenue

status: 0=curve 1=graduated; gnoswapReady/listed: 0|1 gnoswapNote: optional (padv12+); pipes stripped for delimiter safety. listVenue: optional (padv23+); empty if unlisted.

1func ListBuyers(id string) string

source

ListBuyers returns unique buyer addresses (one per line), capped for query size. Only addresses that bought at least once on this pad (UniqueBuyers). Not full GRC20 holders who received tokens via transfer.

1func ListFeeRequired() int64

source

ListFeeRequired is a public alias for UIs / qeval.

1func ListFeeRequiredFor(venueId string) int64

source

ListFeeRequiredFor is venue-aware Create fee for UI preflight.

1func ListIDs() string

source

ListIDs returns newline-separated launch IDs (sorted by AVL key / creation order).

1func ListNeed(id string) string

source

ListNeed is the public query for the Token list wizard (default venue).

1func ListNeedFor(id, venueId string) string

source

ListNeedFor is venue-aware; only gnoswap has a Need adapter today.

1func ListNoteOf(id string) string

source

ListNoteOf returns the listing status note.

1func ListPoolPathOf(id string) string

source

ListPoolPathOf returns the pool path after listing.

1func ListSeedReleasedOf(id string) bool

1func ListVenueOf(id string) string

source

ListVenueOf returns the venue id used for a successful list (or "").

1func ListVenues() string

source

ListVenues returns newline-separated "id|label|enabled|feeHint" (enabled 0|1).

1func ListedOf(id string) bool

source

1func PadAddress() string

source

PadAddress returns this pad realm's bech32 package address (fund WUGNOT here).

1func ParamsInfo() string

source

1func PointsEnabled() bool

source

PointsEnabled reports whether pad notifies pointsv2 after trades/creates.

1func PreferredVenueOf(id string) string

source

PreferredVenueOf returns the Create-time / SetPreferredVenue target.

1func PrepaidBalance(cur realm) int64

source

PrepaidBalance returns caller's claimable WUGNOT credit on this pad.

1func PrepaidOf(addr string) int64

source

PrepaidOf returns claimable credit for an address (read helper).

1func ProtocolAddress() string

source

ProtocolAddress returns the current protocol treasury address (bech32).

1func ProtocolBondFees() int64

source

ProtocolBondFees returns pending create-bond bank ugnot (subset of ProtocolFees).

1func ProtocolFees() int64

source

1func ProtocolFeesPaid() int64

source

ProtocolFeesPaid returns lifetime ugnot already paid out to the treasury.

1func PushProtocolFees(cur realm) int64

source

PushProtocolFees sends pending protocol fees to protocolAddr. Permissionless: anyone may call so treasury can be paid without the protocol key signing (still only pays the configured protocolAddr).

1func ReleaseListSeed(cur realm, id string)

source

ReleaseListSeed sends graduated internal-CPMM seed to the creator for EOA zdex CreatePool:

PoolUgnot as WUGNOT Transfer to creator (EOA may wugnot.Withdraw → ugnot OriginSend)
PoolToken minted as GRC20 to creator (was pad-accounting only)

PoolUgnot/PoolToken kept as listing-size record; reservedWugnot skips via ListSeedReleased. Disables internal SwapBuy/Sell. Creator or protocol may call; assets always go to creator.

1func RemainingRaiseUgnot(id string) int64

source

RemainingRaiseUgnot is net ugnot still needed to hit graduationThreshold() (0 if met/over).

1func Render(path string) string

source

Render provides on-chain discovery (gnoweb). Read-only by convention.

Paths:

Example

1""              - home / list
2token/{id}      - launch detail
3help            - API help

1func ReservedUgnot() int64

source

ReservedUgnot is ugnot the pad must keep for markets + pending claims.

1func ResolveSymbol(symbol string) string

source

1func RetryList(cur realm, id, venueId string) bool

source

RetryList lists a graduated launch on the chosen venue. Permissionless EOA MsgCall. Uses PoolUgnot / PoolToken (curve-spot sized). venueId: empty → PreferredVenue → DefaultListVenue(); unknown/disabled → soft-fail note.

1func RetryListGnoswap(cur realm, id string) bool

source

RetryListGnoswap is the Gnoswap-specific wrapper (compat for existing UI).

1func Sell(cur realm, id string, tokensIn, minWugnotOut int64) int64

source

Sell burns curve tokens and pays WUGNOT (fee on output). minWugnotOut: slippage floor (0 = disabled). User may wugnot.Withdraw to ugnot.

source

SetDefaultListVenue sets the default list venue (protocol only).

1func SetGraduationThreshold(cur realm, ugnot int64)

1func SetListFeeGns(cur realm, gns int64)

source

SetListFeeGns updates Create-time GNS escrow required for new launches. Protocol/deploy wallet only. Does not change already-escrowed launches.

1func SetListVenue(cur realm, id, label string, enabled bool, feeAssetHint string)

source

SetListVenue registers or updates venue metadata (protocol only). Does not add compile-time dispatch — unknown ids stay non-listable until tryListVenue gains a case in a future pad version.

1func SetPointsEnabled(cur realm, on bool)

source

SetPointsEnabled toggles pointsv2 notifications (protocol admin only). pointsv2 must AllowPad(this package path) or OnTrade/OnCreate will panic and revert the trade.

1func SetPreferredVenue(cur realm, id, venueId string)

source

SetPreferredVenue sets the DEX target used when RetryList(id, "") is called. Creator or protocol only; locked once listed. Syncs Create-time GNS escrow (gnoswap locks ListFeeRequired; zdex unlocks/refunds escrow).

1func SwapBuy(cur realm, id string, amountWugnot, minTokensOut int64) int64

source

SwapBuy buys tokens from the graduated internal pool with WUGNOT. amountWugnot: max to spend (Approve pad). minTokensOut: slippage (0 = off). Disabled when listed on Gnoswap (trade via router).

1func SwapSell(cur realm, id string, tokensIn, minWugnotOut int64) int64

source

SwapSell sells tokens into the graduated pool for WUGNOT. minWugnotOut: slippage floor (0 = disabled).

1func TokenIDOf(id string) string

Example

1height|side|ugnot|tokens|priceScaled

side: 0=buy 1=sell 2=open/graduate. Ordered oldest -> newest.

1func Transfer(cur realm, id string, to address, amount int64)

source

Transfer moves GRC20 tokens between addresses (user-initiated).

1func TransferFrom(cur realm, id string, from, to address, amount int64)

source

TransferFrom spends allowance: spender = MsgCall EOA caller. Enables DEX / routers that hold allowance from Approve.

1func TransferProtocol(cur realm, newAddr address)

source

TransferProtocol rotates the protocol fee recipient (current protocol only). Pending protocolFees stay on pad until claimed/pushed to the *new* address.

1func WithdrawProtocolUgnot(cur realm, amount int64) int64

source

WithdrawProtocolUgnot lets the treasury pull free ugnot from the pad bank (e.g. raised backlog after Gnoswap list, to re-wrap as WUGNOT inventory). Capped by free balance; panics if amount > free.
