Introduction

You can use bridge to send tokens from Ethereum network to polygon, For this purpose, the polygon network introduces 2 bridges, each of which has a different mechanism. POS bridge and plasma bridge. POS bridge is faster than plasma and has no time limit for withdrawing tokens. This article talks about POS bridge because it has more number of transactions than plasma.

Due to the limitations of plasma, the use of this bridge is much less than POS. In the following, we will read a short introduction of these two bridges and check the limitations of plasma.

Right Image Shows difference between Plasma and PoS Bridge.

PoS Bridge

POS Bridge has more flexibility and is faster than plasma, while plasma has more security and less flexible .

Due to more flexibility and higher speed, most users or Dapps choose Pos.

Plasma Bridge

One of the limitations of plasma is having a 7-day withdrawal period. Novel users who want to return their tokens to the Ethereum network must wait 7 days for this period to end.

==Approach==

This analysis is about checking the behavior of users after the bridge from Ethereum to Polygon. We want to know what type of transaction was the first transaction of the users after entering the polygon network. And What platforms have these users interacted with?

first of all we have to find users who are depositing assets to polygon from Ethereum chain, for this purpose we should find PoS bridge contract address, which users are interacting with it, 0xa0c68c638235ee32657e8f720a23cec1bfc77c77, since each user has same address on Ethereum and polygon. its easy to find next transaction after bridge on polygon network.

timestamp of bridge transactions for each users should be less than first transaction on polygon chain after bridge, so we can find first transaction of each use by using something like this, timestamp(bridge transaction) < timestamp(first transaction on polygon).

==PoS Bridge Stats==

Lets take a look at PoS Bridge unique users and bridge transactions over time, This chart shows number of unique users who use PoS Bridge reduced over time, mature reason might be due to crypto market conditions , less users = less transaction.

First Transactions After Bridge (Type)

as you can see in charts below most users Transfer their tokens after bridge to other Protocols or addresses. second is Approval, this means users approved some actions on other protocols like approval for swap tokens.

third type of Transactions is Swap , almost 1m transactions are related to swap on different platforms, lets take a look at next pie chart , hop protocol has more first transactions between other platforms, next platforms is quick swap and third is aave gotchi.

10 most popular first destinations ==(Platforms)

1.this is so interesting, first platform users are interacting with is a bridge platform , Hop protocol is a mechanism for transferring tokens over a shared layer 1 network quickly and without trust. It provides customers with a two-pronged token bridge for Ethereum’s layer 2 network.

2.second is a swap platform, QuickSwap is an Automated Market Marker on the Polygon Network. It’s a copy of Uniswap and offers the same liquidity pool model. Users add pairs of tokens to liquidity pools and earn transaction fees from others who swap their tokens using the pools.

3.Third platform is aave gotchi, Aavegotchi is a crypto collectible game built on Ethereum where participants can purchase and grow Aavegotchis, Non-Fungible Token (NFT) avatars used to explore and interact with Aavegotchi's digital universe. Each Aavegotchi avatar is a digital collectible that has unique attributes defined by a rarity score.

Uniswap, aave, balancer and sushiswap platforms are in the next places.

and Metamask and Opensea are two last platforms in our top 10 most popular destinations list.

==Top destinations over time==

Chart below Shows how this destinations places changes over time, in first days of Jun Aave gotchi had more Transactions. and in some days quick swap had more transactions, but in total in most days Hop had more transactions compare to other platforms.

==Conclusions==

In this analysis, we found that the number of Pos bridge transactions has decreased very much in recent days. We have also explained the main reason for this, is the bear market conditions and the decrease of users in the crypto space.

We found the top 10 destinations of users who bridged from the Ethereum network to Polygon, We found that most of the first transactions of these users after Bridge were in the Hop protocol.

we also saw that users used quickswap for swap transactions, And we also saw that the third popular destination of users was a blockchain game called aave gotchi.

almost most of Other destinations was DEX’s like uniswap, balancer and sushiswap also users had interact with metamask swap router and Opensea which is a NFT Marketplace .

So it can be Concluded Most users choose a swap platform after Bridging from Ethereum to Polygon.
