Injective Frontend Wallet

Use this skill before shipping any Injective browser transaction flow. Injective looks Cosmos-shaped at the transaction layer, but its accounts and public keys are Ethereum-style. Generic Cosmos frontend code often reaches the quote screen and then fails at signing or CheckTx.

First Decision

Choose the signing stack deliberately:

1. Prefer @injectivelabs/sdk-ts / Injective broadcaster utilities when the app already uses the Injective SDK and the transaction type is covered.
2. Use CosmJS for CosmWasm frontends only if you explicitly handle Injective account and pubkey compatibility.
3. Do not assume a Keplr/Leap inj1... address means generic /cosmos.crypto.secp256k1.PubKey signing will validate on-chain.
