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.
## Example calls
```sh
# Mint 1000 MINI to yourself
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/erc20" \
-func Mint -args "<your-addr>" -args 1000 \
-gas-fee 1000000ugnot -gas-wanted 2000000 -broadcast -chainid sapphire-1 <key>
# Transfer 250 MINI to another account
gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/erc20" \
-func Transfer -args "<recipient-addr>" -args 250 \
-gas-fee 1000000ugnot -gas-wanted 2000000 -broadcast -chainid sapphire-1 <key>
```
