# 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.
