Legacy Address convention

Legacy Address convention

In EtherealNetwork chain 2.0 generation, we used to have Legacy Addresses (that always start with V). Those addresses essentially are 20 bytes Ethereum-like addresses but encoded differently on UI. The difference is that instead of a hex string prefixed with 0x, the Legacy address is extended with checksum (4 extra bytes), encoded with Base58, and prefixed with 'V'.

'V' + base58(20-bytes-address + 4-bytes-checksum)

Examples:

EVM Address	Legacy Address
0x32Be343B94f860124dC4fEe278FDCBD38C102D88	V5dJeCa7bmkqmZF53TqjRbnB4fG6hxuu4f
0x000000000000000000000000000000000000000f	V111111111111111111111111112jSS6vy
