Tiny web3 protocols and applications.

The aim is to keep it simple, quick to implement and interesting to learn Solidity.

Inspired by lil-web3 by Miguel Piedrafita.

Tiny ENS

Map human-readable names like vitalik.eth to machine-readable identifiers such as Ethereum addresses like 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and support the reverse resolution.

	interface ITinyENS {
	/// @notice Register a new ENS name and link it to an address.
	/// @param name The ENS name to register.
	function register(string memory name) external;
	/// @notice Update the ENS name linked to an address.
	/// @param newName The new ENS name.
	function update(string memory newName) external;
	/// @notice Resolve the address associated with a given ENS name.
	/// @param name The ENS name to resolve.
	/// @return The address associated with the ENS name.
	function resolve(string memory name) external view returns (address);
	/// @notice Reverse resolve an address to its associated ENS name.
	/// @param targetAddress The target address to reverse resolve.
	/// @return The ENS name associated with the address.
	function reverse(address targetAddress) external view returns (string memory);

Last Call Jackpot

A game where the last caller, before a 10-block inactivity period, wins the entire contract's ETH balance.

	interface ILastCallJackpot {
	/// @notice Call the contract and attempt to win the jackpot.
	function call() external payable;
