Prebuilt contract exports
Five Contract values, each with real compiled bytecode and deployedBytecode, exported from
the package root.
import {
SimpleContract,
ERC20,
ERC721,
ErrorContract,
AdvancedContract,
} from '@tevm/contract'None of them has an address — call withAddress first.
For usage examples see the prebuilt contracts guide. This page is the surface summary.
SimpleContract
Name: SimpleContract. A counter with storage, a getter, a setter, and an event.
| Member | Signature |
|---|---|
| constructor | constructor(uint256 initialValue) |
| read | get() view returns (uint256) |
| write | set(uint256 newValue) |
| events | ValueSet(uint256 newValue) |
ERC20
Name: OzERC20. The OpenZeppelin ERC-20 implementation.
| Member | Signature |
|---|---|
| constructor | constructor(string name, string symbol) |
| read | name(), symbol(), decimals(), totalSupply(), balanceOf(address), allowance(address, address) |
| write | approve(address spender, uint256 value), transfer(address to, uint256 value), transferFrom(address from, address to, uint256 value) |
| events | Transfer(address indexed, address indexed, uint256), Approval(address indexed, address indexed, uint256) |
| errors | ERC20InsufficientBalance, ERC20InsufficientAllowance, ERC20InvalidApprover, ERC20InvalidReceiver, ERC20InvalidSender, ERC20InvalidSpender |
ERC721
Name: OzERC721. The OpenZeppelin ERC-721 implementation, with the standard NFT surface,
Transfer/Approval/ApprovalForAll events, and the OZ ERC-721 custom errors.
| Member | Signature |
|---|---|
| constructor | constructor(string name, string symbol) |
ErrorContract
Name: ErrorContract. Every revert flavour behind a zero-argument function — custom errors with
and without parameters, string reverts, bare reverts, and the four panic codes. No constructor
arguments.
| Errors | SimpleError(), ErrorWithSingleParam(uint256), ErrorWithMultipleParams(string, bytes32, address[]) |
|---|---|
| Reverts | revertWithSimpleCustomError, revertWithCustomErrorSingleParam, revertWithCustomErrorMultipleParams, revertWithStringError, revertWithRequireAndMessage, revertWithRequireNoMessage, revertWithoutMessage |
| Panics | panicWithAssertFailure, panicWithArithmeticOverflow, panicWithDivisionByZero, panicWithArrayOutOfBounds |
| Other | errorOutOfGas, errorWithInvalidOpcode |
AdvancedContract
Name: AdvancedContract. Multiple storage types, an external call, and a delegatecall. Its
constructor deploys a math-helper contract as a side effect.
| Member | Signature |
|---|---|
| constructor | constructor(uint256 initialNumber, bool initialBool, string initialString, address initialAddress) |
| read | getNumber(), getBool(), getString(), getAddress(), getAllValues(), mathHelperAddress() |
| write | setNumber(uint256), setBool(bool), setString(string), setAddress(address), setAllValues(uint256, bool, string, address), setMathHelperAddress(address), callMathHelper(uint256), delegateCallMathHelper(uint256) |
| events | NumberSet, BoolSet, StringSet, AddressSet, AllValuesSet, ExternalCallResult, DelegateCallResult |
