Solidity ERC721
solidity-erc721Generate ERC-721 non-fungible token contract source code with configurable options for minting, burning, pausing, and upgrades. Returns Solidity code in Markdown.
Instructions
Make a non-fungible token per the ERC-721 standard.
Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| info | No | Metadata about the contract and author | |
| name | Yes | The name of the contract | |
| votes | No | Whether to keep track of individual units for voting in on-chain governance. Voting durations can be expressed as block numbers or timestamps (defaulting to block number if not specified). | |
| access | No | The type of access control to provision. Ownable is a simple mechanism with a single account authorized for all privileged actions. Roles is a flexible mechanism with a separate role for each privileged action. A role can have many authorized accounts. Managed enables a central contract to define a policy that allows certain callers to access certain functions. | |
| symbol | Yes | The short symbol for the token | |
| baseUri | No | A base uri for the token | |
| burnable | No | Whether token holders will be able to destroy their tokens | |
| mintable | No | Whether privileged accounts will be able to create more supply or emit more tokens | |
| pausable | No | Whether privileged accounts will be able to pause specifically marked functionality. Useful for emergency response. | |
| enumerable | No | Whether to allow on-chain enumeration of all tokens or those owned by an account. Increases gas cost of transfers. | |
| uriStorage | No | Allows updating token URIs for individual token IDs | |
| incremental | No | Whether new tokens will be automatically assigned an incremental id | |
| upgradeable | No | Whether the smart contract is upgradeable. Transparent uses more complex proxy with higher overhead, requires less changes in your contract. Can also be used with beacons. UUPS uses simpler proxy with less overhead, requires including extra code in your contract. Allows flexibility for authorizing upgrades. | |
| namespacePrefix | No | The prefix for ERC-7201 namespace identifiers. It should be derived from the project name or a unique naming convention specific to the project. Used only if the contract includes storage variables and upgradeability is enabled. Default is "myProject". | |
| crossChainBridging | No | Whether to embed an ERC-7786 based bridge directly in the token contract, making it natively crosschain. Crosschain transfers with registered counterparts burn the token on the source chain and mint it on the destination chain. If also using incremental token ids, mint only on a single chain and link counterparts without minting, otherwise colliding ids can strand bridged tokens. | |
| crossChainLinkAllowOverride | No | Whether to allow replacing a crosschain link that has already been registered. Only used if crossChainBridging is set to "erc7786native". |
