MiniToken (ERC-20)

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A minimal fungible-token realm for gno.land (gno 0.9 / sapphire), porting the classic Solidity ERC-20 idea. It keeps package-level state — a balances map, a total supply, and per-owner allowances — behind gno 0.9 crossing functions that authenticate the caller via cur.IsCurrent() + cur.Previous(). Render returns a Markdown dashboard with the token metadata and a table of holders.

Realm path: gno.land/r/REPLACE_ADDR/erc20 (deploy address injected at deploy time).

Exported API

  • Mint(cur realm, to address, amount uint64) — create new tokens for to.
  • Transfer(cur realm, to address, amount uint64) — send tokens from the caller.
  • Approve(cur realm, spender address, amount uint64) — grant a spending allowance.
  • TransferFrom(cur realm, from, to address, amount uint64) — spend an allowance.
  • BalanceOf(holder address) uint64 · Allowance(owner, spender address) uint64
  • TotalSupply() uint64 · Name() string · Symbol() string
  • Render(path string) string — Markdown view for gnoweb.
