GavCoin

The contract defines a token with subdivisible units and a dynamic issuance model based on tranches. Tokens are sold in fixed-size tranches at increasing prices, with each tranche raising the token price by a fixed increment. Purchases generate on-chain receipts that become refundable after a defined activation period, allowing holders to return tokens for ether at their purchase price. Transfers, approvals, and allowances follow an ERC-20–style interface, while issuance and refunds are handled directly by the contract.

GavCoin is an Ethereum smart contract that implements a fungible token with ERC-20–style transfer and approval functions alongside a built-in buy-in, pricing, and refund mechanism. The contract logic corresponds to a later GavCoin implementation published by Gavin Wood on Github a week after.
