Chain and contract

Setting	Value
Cosmos chain ID	`injective-888`
EIP-712 chain ID	`1439`
Chain gRPC	`testnet-grpc.injective.dev:443`
Chain LCD	`https://testnet.sentry.lcd.injective.network`
RFQ contract	`inj1qw7jk82hjvf79tnjykux6zacuh9gl0z0wl3ruk`
Contract version	`v0.2.0`
Contract code ID	`39933`
Allowed EVM chain IDs	`1439`, `11155111`
Explorer	`https://testnet.explorer.injective.network`

injective-888 and 1439 are both required, but they are not interchangeable. quote.chain_id is the Cosmos chain ID and must be injective-888 on testnet. quote.evm_chain_id and the EIP-712 domain chainId use 1439. Raw MakerStream quote payloads use snake_case field names; passing 1439 as quote.chain_id is a known integration failure mode.

Context	Testnet value
EIP-712 domain `chainId`	`1439`
Quote payload `evm_chain_id`	`1439`
Quote payload `chain_id`	`injective-888`

RFQ indexer endpoints

Service	Endpoint
WebSocket base	`wss://testnet.rfq.ws.injective.network/injective_rfq_rpc.InjectiveRfqRPC`
MakerStream WSS	`wss://testnet.rfq.ws.injective.network/injective_rfq_rpc.InjectiveRfqRPC/MakerStream`
TakerStream WSS	`wss://testnet.rfq.ws.injective.network/injective_rfq_rpc.InjectiveRfqRPC/TakerStream`
gRPC-web base	`https://testnet.rfq.grpc.injective.network/injective_rfq_rpc.InjectiveRfqRPC`
Native gRPC	`testnet.rfq.grpc.injective.network:443`
HTTP	`https://testnet.rfq.injective.network`

The public service alias is injective_rfq_rpc.InjectiveRfqRPC. The deployed paths use underscores and InjectiveRfqRPC; do not substitute the internal proto package name. Most SDK clients store the WebSocket base endpoint and append /MakerStream or /TakerStream internally. Do not append the stream path twice.

Tokens

Asset	Denom	Use
INJ	`inj`	Gas
USDC	`erc20:0x0C382e685bbeeFE5d3d9C29e29E341fEE8E84C5d`	RFQ margin

Fund both the bank balance for gas and the exchange subaccount for margin. Maker margin must be available in the subaccount nonce registered for that maker. Faucet: https://testnet-faucet.injective.dev

Mainnet signing contrast

Mainnet uses Cosmos chain ID injective-1 and EIP-712 chain ID 1776. Pull both values from environment config instead of hardcoding when writing reusable clients.

Testnet runs a newer contract than mainnet. Testnet is on RFQ v0.2.0 (code ID 39933), which adds SigAuth Registry support and quote-level failure isolation. Mainnet is on RFQ v0.1.3 (code ID 2064) until the v0.2.0 rollout. The testnet contract address is unchanged. Fee configuration (taker fee 0, maker fee 0.0004), max_quotes (25), and max_evict (4) match mainnet. Mainnet allows EVM chain IDs 1 and 1776.
