Migrating from Ethereum

Resources for migrating from Ethereum:

1. Video tutorial on Application Development on Aion.
2. Video tutorial on Migrating Your DApp.
3. Code examples for frequently used functionality.

The following table shows a list of differences between Aion and Ethereum that should be taken into consideration when migrating already implemented smart contracts from Ethereum to Aion:

	Ethereum	Aion
data word	256 bits	128 bits
local variable count	16 data word (of 256 bits)	16 data word (of 128 bits)
int size	int8 – int256	int8 – int128
uint size	uint8 – uint256	uint8 – uint128
inline assembly	supported	not supported (currently)
address	20 bytes	32 bytes
hash function (signatures & wallet)	Keccak-256	Blake2b
signature function	ECDSA – curve secp256k1	ECDSA - curve ED25519
compilers	Solidity, LLL, Serpent	Solidity
