Invalid order signature #24

Closed GoldRat closed 6 years ago

GoldRat commented 6 years ago

I'm trying to open order through API.

This is my payload: {"contractAddress":"0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208", "tokenBuy":"0x0000000000000000000000000000000000000000", "amountBuy":"50000000000000000", "tokenSell":"0xcdcfc0f66c522fd086a1b725ea3c0eeb9f9e8814", "amountSell":"100000000000000000000", "expires":10000, "nonce":1, "address":"0x351296f44a5bf3f05eaa7d78a560f50dd736b728", "v":28, "r":"0xf58101acdb189a21a18d4b504b124dbfd3cfe67126b2fdc132eb3b3dea86664a", "s":"0x50100b3e391b4fed0e6dcf81e3c833b971506b48d5c837bb81bbb1c6240c4c61"}

Private key: 0xce8291ae3e3f6db1f7d763fa543c1aa7c76080f69880d695bf131f4ca7bde67a

But it returns the error: {"error":"Invalid order signature. Please try again."}

What's wrong with order signature? What v, r, s parameters values should be in this case? Please, help!

Hm, I had the same issue, looks like it's server problem. Sometimes it disappears and u can use api normally

Is there any examples to test hashing and signing? Like input parameters -> raw hash -> salted hash - > v, r, s

The documentation includes a JS code sample for creating signatures, and I've added a code sample with more detailed instructions specific to the OP's case to the other issue opened by the OP at https://github.com/AuroraDAO/idex-api-docs/issues/26. Closing.

I've tested my algorithm by example you've given at #26. The result is perfect match to your r, s, v values. However the error "Invalid order signature" still appears (not always but sometimes).
