erc20/v0 package

Overview

Package erc20 implements MiniToken, a minimal fungible token modeled on the Solidity ERC-20 idea, ported to gno.land (gno 0.9 / sapphire).

State is package-level and persistent. All state-mutating exported functions are crossing functions (they take `cur realm` as the first parameter) per the gno 0.9 interrealm convention, and identify the caller via cur.Previous().Address() after checking cur.IsCurrent().

Function

TransferFrom

func TransferFrom(cur realm, from, to address, amount uint64)

TransferFrom moves `amount` tokens from `from` to `to`, spending the caller's allowance granted by `from`. Crossing function.

Params

Command

# WARNING: This command is running in an INSECURE mode.
# It is strongly recommended to use a hardware device for signing
# and avoid trusting any computer connected to the internet,
# as your private keys could be exposed.
