Understanding smart contracts
Smart contracts are programs deployed on the blockchain. Their functions are executed with transactions.
Starton allows you to access a collection of audited smart contracts covering most frequent use cases and needs. It currently includes flavours of the classic ERC20 (cryptocurrency), ERC721 and ERC1155 (NFT) smart contracts.
Smart contract templates
ERC20 - Creating your fungible token
The ERC20 is a smart contract standard made for fungible tokens (i.e: interchangeable tokens like coins).
| Smart Contract | Description | Blockchain |
|---|---|---|
| ERC20 Token with fixed supply | This meta-transaction version enables you to send transactions on behalf of your users so they can use their tokens without having to pay for gas fees. |     |
| ERC20 Token with mintable supply | This meta-transaction enables you to send transactions on behalf of your users so they can use their tokens without having to pay for gas fees. | |
ERC721 - Deploy and sell your one-to-many NFTs
The ERC721 is a smart contract standard which is specialised in single-copy Non Fungible Tokens (NFT) and out-of-the-box compatible with Opensea. In an ERC721, every NFT is unique which means you have to reference the content for each NFT.

The ERC721 can still be used to upload several copies of the same content but is less optimised for this use case than the ERC1155.

ERC1155 - Deploy and sell one-to-many NFTs
The ERC1155 is a smart contract standard which is specialised in multiple-copies Non Fungible Tokens (NFT) and out-of-the-box compatible with Opensea. The ERC1155 enables you to create “collections” containing several copies of the same NFT.
