englishauction/v0 package

Overview

Package englishauction is an idiomatic gno.land port of the classic Solidity English (ascending-bid) auction. Anyone can Start an auction for a named item with a duration in blocks; bidders call Bid with a strictly increasing amount. The previous highest bid becomes refundable (claim it with Withdraw). After the auction's end height anyone may call End, awarding the item to the highest bidder. Auctions and pending refunds live in ordered avl trees so Render can iterate deterministically.

Functions

Bid

func Bid(cur realm, id int64, amount uint64)
Ask AI Claude ChatGPT

Bid places a bid of `amount` on auction `id`. It must strictly exceed the current highest bid. The displaced highest bid becomes refundable to its bidder via Withdraw.
