📔Smart Contracts

We have a repository ink-examples, in which you find a number of contracts written in ink!. Some of the most interesting ones:

Our "Hello, World!". » view example

An ERC-20 implementation. » view example

» view ERC-721 » view ERC-1155

An upgradeable contract. » view example

A multi-signature wallet. » view example

Allow runtime access. » view example

Cross-contract calls. » view example

Implements an Erc20 trait. » view example

Simple DomainNameService. » view example

If not noted otherwise in the readme, to build a single example navigate to the root of the example and run:

cargo contract build

As a result you'll get a file target/<example-name>.wasm file, a <example-name>.json file and a <example-name>.contract file in the target/ folder of your contract. The .contract file combines the Wasm and metadata into one file and needs to be used when deploying the contract.

For further information, please have a look at the Deploy your Contract section.
