Use this page as a compact error index. For step-by-step triage, see [Troubleshooting](/sdk-trading/troubleshooting). *** ## Quote and settlement errors ### `signature verification failed` / `invalid_signature` The maker signature does not recover against the submitted quote fields. Common causes: * Signed decimal string differs from the sent decimal string. * EVM chain ID in the EIP-712 domain is wrong (`1439` testnet, `1776` mainnet). * `quote.chain_id` was set to the EVM chain ID instead of the Cosmos chain ID, or raw JSON used a camelCase chain ID field instead of `quote.chain_id`. * RFQ contract address in the EIP-712 domain is stale. * Field order differs from the v2 `SignQuote` schema. Fix: compare the exact typed-data message to the exact wire payload. On testnet, EIP-712 domain `chainId` and quote `evm_chain_id` are `1439`, but quote `chain_id` is `injective-888`. Use [Building and signing quotes](/sdk-trading/signing-quotes) as the field-order reference. *** ### `quote expired` The quote's `expiry` timestamp was not greater than block time when settlement executed. Fix: keep clocks synced and avoid slow work after receiving an RFQ. Live maker quotes must be at least `now_ms + 1_500`; extending expiry may reduce rejects and improve match odds, but increases stale-price risk. *** ### `price exceeds worst_price` / `worst price exceeds limit` The maker quote is worse than the taker's signed limit. * Long taker: quote price must be less than or equal to `worst_price`. * Short taker: quote price must be greater than or equal to `worst_price`. Fix: makers should read the taker's `worst_price`, price within that bound, and use human-scale mark prices from v2 endpoints. Do not apply 1e18 scaling to mark or quote prices. *** ### `No quote was filled` The transaction reached settlement, but every submitted quote was skipped or no submitted quote satisfied the taker's fill constraints. Common causes: * Quote expired. * Quote signature failed. * Maker subaccount nonce does not match `list_makers`. * Maker or taker margin is insufficient. * Quote violated `worst_price` or mark-band checks. * `min_fill_quantity` or unfilled-action rules could not be satisfied. Fix: inspect per-quote settlement results, then verify maker registration, subaccount nonce, balances, and exact signed fields. *** ### `unauthorized` / `authorization not found` The required authz grant from taker or maker to the RFQ contract is missing, expired, or granted to the wrong contract address. Fix: re-run [Authorization setup](/sdk-trading/authz), then query grants for both wallets. *** ### `insufficient funds` / `insufficient margin` The wallet or exchange subaccount lacks INJ for gas or USDC margin. Fix: fund the bank balance for gas and the correct exchange subaccount for margin. Maker margin must be in the registered `maker_subaccount_nonce`; if registration returns `null`, use nonce `0`. *** ### `maker not whitelisted` / `not_whitelisted` The maker address is not registered on the RFQ contract, or a first-page `list_makers` query missed it. Fix: use a paginated helper such as `ContractClient.is_maker_registered()`. If still absent, complete [Maker whitelist](/sdk-trading/maker-whitelist). *** ## Stream errors ### Maker stream connects but receives no RFQs The MakerStream auth challenge was not answered or was answered with an invalid signature. Fix: configure the maker client with `auth_private_key`, `auth_evm_chain_id`, and `auth_contract_address`. If implementing manually, sign `StreamAuthChallenge` with the same EIP-712 domain used for quotes. *** ### Taker receives no quotes Common causes: * Taker collects quotes for a locally generated ID instead of the ACK-returned `rfq_id`. * Maker quote was rejected before routing. * Maker is disconnected, not whitelisted, or not quoting that market. * Taker connected with the wrong `request_address`. Fix: log the request ACK, collect quotes for `ack["rfq_id"]`, and check maker-side `quote_ack` / quote error logs. *** ### `rfq_id` mismatch Quotes arrive for a different request than the one your client expects. Fix: treat `client_id` as client correlation only. The indexer assigns `rfq_id`; use the ACK-returned value for maker filtering, taker quote collection, and settlement. *** ## Signed-intent errors ### `invalid_intent_signature` The signed taker intent fields differ from the submitted fields, or the EIP-712 domain is wrong. Fix: keep `deadline_ms`, `worst_price`, `trigger_type`, `trigger_price`, `epoch`, `lane_version`, `rfq_id`, and `market_id` identical between signing and submission. Send v2 fields on the TakerStream payload. *** ### `trigger_not_satisfied` The executor submitted `AcceptSignedIntent`, but the contract re-read mark price and the trigger condition was no longer true. Fix: the executor should retry according to its trigger-order policy when the condition is true again, as long as the intent has not expired or been cancelled. *** ### `rfq_id mismatch` The maker quote's taker address plus `rfq_id` does not match the taker plus `rfq_id` embedded in the signed taker intent. Fix: the executor must pair each signed intent with quotes bound to that exact taker plus `rfq_id`. *** ### `stale epoch` / `stale lane` The taker cancelled all intents or cancelled the market lane after signing this intent. Fix: read current `epoch` and `lane_version` before signing a replacement intent.
