Overview

Parametric GRC20 realm for gno.land.

All configuration (name, symbol, decimals, supply, metadata) lives in config.gno. This file holds only the logic, which is not meant to be edited.

The realm:

  • creates a GRC20 token through gno.land/p/nt/grc20/v0
  • registers it with gno.land/r/nt/grc20reg/v0 (required to be discoverable by GnoSwap, wallets and explorers)
  • mints the initial supply to the deploying address
  • exposes the GRC20 methods as top-level functions callable via MsgCall
  • enforces a hard ceiling (maxSupply) on minting
  • lets the owner give up minting forever (DropOwnership)

Holders

func Holders() int

Holders returns the number of addresses with a non-zero balance.

Command

gnokey query vm/qeval -remote "https://rpc.gno.land" -data "gno.land/r/nym-thegnomic001/gnomic.Holders()"

Result

MaxSupply

func MaxSupply() int64

MaxSupply returns the hard ceiling in base units: it caps the cumulative amount ever minted, not the circulating supply.

Command

gnokey query vm/qeval -remote "https://rpc.gno.land" -data "gno.land/r/nym-thegnomic001/gnomic.MaxSupply()"

Result

Mint

func Mint(cur realm, to address, amount int64)

Mint creates amount (base units) in favour of to. Owner only, and never beyond maxSupply. After DropOwnership this function is unusable forever: the supply becomes immutable upwards.
