Aggregation exchanges provide services to users by aggregating token liquidity pools built by third-party DEXs. The point where aggregation exchanges compete with each other is who can complete the service faster and cheaper. Because the DEX that builds the liquidity pool is different, the fees charged and the token pool built are also different, so the aggregation exchange needs to find the liquidity pool of the token first and then plan a reasonable path. After comparing the handling fees, choose the optimal one. The path is provided to the user.

Galxe OAT

Compared with other aggregation exchanges, it also has the function of exchanging more for one. There may be a lot of handling fees on the main network, but the experience on Layer2 and side chains is extremely smooth and cheap. I don't know if the official will launch a one-to-many function in the future.

At present, ODOS has launched Ethereum, Polygon, and Arbitrum public chains, and launched an OAT collection activity in conjunction with Galaxy. Before that, the early supporter OAT was launched. I shared it on Twitter before, and you can get it by following and reposting the official Twitter. A total of 40,000 were minted.

End time: 2022.10.20

And the test OAT of the public chain needs to complete the corresponding test tasks before it can be minted.

Ethereum has a total of 58 OATs, and you need to collect 32 of them to get additional NFT airdrops. The task is very simple, that is, exchange corresponding tokens (equivalent to 1000 USDC) in ODOS.

Because the liquidity of some tokens is not very good, and the paths they choose are different, some transactions will have a large price difference, and the handling fees will also vary. I collected 33 OATs myself, and the final handling fee and slip The loss caused by the point is almost 330u.

If you have sufficient funds, you can use ETH/USDC to exchange other tokens respectively. Most pools will be built around ETH and stable coins without excessive slippage and handling fees. And if you have less funds, in order to avoid slippage losses, you may choose to exchange other tokens and then exchange them back to USDC for exchange, which will incur a lot of additional handling fees.

And I came up with an idea in the process of doing the task, which can divide the tokens you need to exchange into two categories, mainstream and non-mainstream. Generally, mainstream tokens will have many liquidity pools built around them, while non-mainstream tokens may not have so many pools. We can use the "non-mainstream-mainstream-non-mainstream" process to complete the task, avoiding as much as possible the additional handling fees caused by multiple exchanges.

If you want to collect 58 OATs, you can consider the above idea. If you only want to collect 32, you can pass the non-mainstream tokens, and then complete the task of mainstream tokens. Generally, slippage and handling fees will be in Within 10u.

Arbitrum and Polygon are relatively simple. You only need to exchange 20 USDC equivalent tokens to complete the task, but you need to collect all OATs to get additional Gold NFTs. Because of the low capital required and low handling fees, it only costs about 30u to complete all the tasks of the two public chains.

It should be noted that the OAT collected on the public chain needs to be held for 14 days after the event ends in order to obtain additional Gold NFT.

Because the ODOS team joined The Graph as a core developer, and The Graph’s GRT airdrop was one of the four major airdrops in the currency circle in 2020, naturally users on the chain have great expectations for ODOS, and it is generally believed that NFT is the Proof of its airdropped tokens.

At present, due to the high cost required, there are not many people involved in Ethereum, while Arbitrum and Polygon, which are relatively simple and have very little cost, have become the main battlefield for introverts. At the beginning, I thought of participating in random, but after actually using it, I have collected the OAT of three public chains.
