• I'm stuck like this, can anyone help?

Trying to fill some order but unsuccessful. Investigating further turns out that order hash doesn't match from onchain.

Steps to reproduce:

const res = await axios.get('https://limit-orders.1inch.io/v2.0/1/limit-order/all', {
        params: {
          page: 1,
          limit: 100,
          statuses: '[1]',
        },
      })

const order = res.data[20]

const contract = new Contract('0x119c71d3bbac22029622cbaec24854d3d32d2828', IOneInchLimitOrderProtocol.abi, provider)
const orderHash = await contract.hashOrder(order.data)
assert(order.orderHash === orderHash)

This issue is stale because it has been open 45 days with no activity.

I had very old order and I forgot about it

Right now 1inch token price is 0.8 USDT.
USDT was not approved, and when I approved USDT - old orders was bought 1inch tokens for 1.25 USDT - Whaaat?

Pls, fix it in the protocol - don't buy tokens higher than market (amazing idea!).
And fix it in your interface - if I forgot about this orders, it can notify me before approving USDT.. I don't want buy 1inch token right now =)
Thanks, guys for your work!

Is it possible to use your limit order protocol for the cases when both the maker and the taker are the same address?

I'm thinking about using it to accept crypto payments for the merchants.
In my scenario, customers pay for products from the customer's wallet with the conversion of a token into stable coin in the background utilizing 1inch swap, with the following involvement of order.interaction API and withdrawal of stable coin into the merchant's wallet.

Following this Idea I'm trying to swap eth with dai assets but after all the balances aren't changing.
Cudl you take a look, please?

expect(await this.weth.balanceOf(addr1)).not.to.be.bignumber.equal('1000000');
expect(await this.dai.balanceOf(addr1)).not.to.be.bignumber.equal('1000000');

See #92 pull request opened with the test added.

Is there a Websocket API for subscribing to order updates?
Similar to: https://docs.0x.org/0x-api-orderbook/api-references/websocket-api

If it does not exist, would then request this feature.

I'm trying it on BSC network,

Here is the order that i try to fill

So when i try to recover ecdsa with orderHash and signature in the api response it returns maker address but when i sent the order to my contract and hash it using the same hashing algorithm at 0x1e38eff998df9d3669e32f4ff400031385bf6362 it returns a different hash that is not in the api response

Prize Title

Margin trading on the 1inch Limit Order Protocol

Prize Bounty

3,000 USD in 1INCH Tokens

Challenge Description

Write a smart contract enabling the creation of limit orders for margin trading on the 1inch Limit Order Protocol.

1inch limit order protocol is a set of smart contracts, that can work on any EVM based blockchains (Ethereum, Binance Smart Chain, Polygon, etc.). Key features of the protocol is extreme flexibility and high gas efficiency that achieved by using two different order types - regular Limit Order and RFQ Order.
Smart Contract allows users to place limit orders and RFQ Orders, that later could be filled on-chain. Both type of orders is a data structure created off-chain and signed according to EIP-712.

Judging Criteria

Solution must be unique and it must work. We expect demo, not presentations
We'll do a code review to ensure code quality to make the final decision.

Hi,

I'd like to make a limit order, with a wallet on Trezor (not using Metamask, as this seems to be not supported yet).
I get the error:

The signing of a limit order in your wallet failed. Please, use another wallet that supports the method signTypedData_v4

Based on Trezor, this should now be supported also on Trezor ONE - since the firmware release in Jan.
Please see:
trezor/trezor-firmware#2128
and
trezor/trezor-firmware#1970

Is this something you can solve on 1inch side?
Thanks!

A fully onchain DEX aggrator will allow DeFi building blocks for cotrader.com and others.

Prices should be competitive with other DEX aggregator options..

Users can get prices and execute a split trade that gets the max tokens possible at the lowest prices available by using a combination of dexs, especially AMM Swap DEXs including Kyber, Bancor, Uniswap, Oasis.
