Experimental Contracts

A second Ping deployment, pointed at a different Pong

Target contract.

A minimal getter/setter proxy from the Oraclize team. set() forwards calls to a hardcoded target contract, get() returns constant 255.

Controller contract.

A 57-byte test contract: set() stores the transaction's ether value into storage slot 0, and get() reads it back.

A 57-byte test contract: set() stores the transaction's ether value into storage slot 0, and get() reads it back.

Pool5x contract.

Winning entry of the Programmable Assets challenge at Hack The Block London (September 2015), built by Francesco Canessa, Kristina Butkute, and Thomas Bertani (

A 115-byte contract with two functions, one() and two(), which write the constants 1 and 2 into the same storage slot.

A Pong contract variant that receives ETH via send(), testing value transfer between contracts.

A 71-byte contract whose single function, pong(), immediately sends the caller's ether back to them.

An 86-byte contract with one function, test1(bytes32), which writes its argument into the single storage slot and nothing else.

A tutorial contract holding a 3 by 3 grid of tile structs, deployed 30 September 2015.

A second ArrayPasser deployment from Cyrus Adkisson's Solidity walkthrough

A tutorial contract testing fixed-size array passing as function parameters in Solidity.
