Injective needs to parse and handle transactions routed for both the EVM and for the Cosmos hub. We
attempt to achieve this by mimicking Geth's
structure and treat it as a unique Cosmos SDK message type. An Ethereum transaction is a single
sdk.Msg contained in an
auth.StdTx. All relevant Ethereum
transaction information is contained in this message. This includes the signature, gas, payload,
Being that Injective implements the Tendermint ABCI application interface, as transactions are
consumed, they are passed through a series of handlers. Once such handler, the
responsible for performing preliminary message execution business logic such as fee payment,
signature verification, etc. This is particular to Cosmos SDK routed transactions. Ethereum routed
transactions will bypass this as the EVM handles the same business logic.
Ethereum routed transactions coming from a Web3 source are expected to be RLP encoded, however all internal interaction between Injective and Tendermint will utilize one of the supported encoding formats: Protobuf and Amino.
# Transaction formats
- Cosmos transactions
- Ethereum transaction
Injective supports EIP-155
Transaction is expected to have a single signature for Ethereum routed transactions.
However, just as in Cosmos, Injective will support multiple signers for non-Ethereum transactions.
Signatures over the
Transaction type are identical to Ethereum and the signatures will not be
duplicated in the embedding
