# Accounts
This document describes the in-built accounts system of Injective.
# Pre-requisite Readings
# Injective Accounts
Injective defines its own custom Account
type that uses Ethereum's ECDSA secp256k1 curve for keys. This
satisfies the EIP84 (opens new window) for full BIP44 (opens new window) paths.
The root HD path for Injective-based accounts is m/44'/60'/0'/0
.
# Addresses and Public Keys
There are 3 main types of Addresses
/PubKeys
available by default on Injective:
- Addresses and Keys for accounts, which identify users (e.g. the sender of a
message
). They are derived using theeth_secp256k1
curve. - Addresses and Keys for validator operators, which identify the operators of validators. They are derived using the
eth_secp256k1
curve. - Addresses and Keys for consensus nodes, which identify the validator nodes participating in consensus. They are derived using the
ed25519
curve.
Address bech32 Prefix | Pubkey bech32 Prefix | Curve | Address byte length | Pubkey byte length | |
---|---|---|---|---|---|
Accounts | inj | injpub | eth_secp256k1 | 20 | 33 (compressed) |
Validator Operator | injvaloper | injvaloperpub | eth_secp256k1 | 20 | 33 (compressed) |
Consensus Nodes | injvalcons | injvalconspub | ed25519 | 20 | 32 |
# Address formats for clients
EthAccount
s can be represented in both Bech32 (opens new window) and hex format for Ethereum's Web3 tooling compatibility.
The Bech32 format is the default format for Cosmos-SDK queries and transactions through CLI and REST
clients. The hex format on the other hand, is the Ethereum common.Address
representation of a
Cosmos sdk.AccAddress
.
- Address (Bech32):
inj14au322k9munkmx5wrchz9q30juf5wjgz2cfqku
- Address (EIP55 (opens new window) Hex):
0xAF79152AC5dF276D9A8e1E2E22822f9713474902
- Compressed Public Key:
{"@type":"/injective.crypto.v1beta1.ethsecp256k1.PubKey","key":"ApNNebT58zlZxO2yjHiRTJ7a7ufjIzeq5HhLrbmtg9Y/"}
You can query an account address using the Cosmos CLI or REST clients:
See the Swagger API (opens new window) reference for the full docs on the accounts API.
The Cosmos SDK Keyring output (i.e injectived keys
) only supports addresses in Bech32 format.
