Ethereum

Addresses

Ethereum addresses are 20-byte hashes, identical to Ethereum proper.

In Instructions

In Instructions may be created in one of two ways.

  1. Have an EOA call transfer or transferFrom on an ERC20, appending the encoded InInstruction directly after the calldata. origin defaults to the party transferred from.
  2. Call inInstruction on the Router. origin defaults to msg.sender.

Out Instructions

data is limited to 512 bytes.

If data isn't provided or is malformed, ETH transfers will execute with 5,000 gas and token transfers with 100,000 gas.

If data is provided and well-formed, destination is ignored and the Ethereum Router will construct and call a new contract to proxy the contained calls. The transfer executes to the constructed contract as above, before the constructed contract is called with the calls inside data. The sandboxed execution has a gas limit of 350,000.
