Problem with bridging assets

Hellow i tried to bridge assets.

From Matic to Fantom.
https://polygonscan.com/tx/0x37a7e5a17d9019a0cf988a9d1c546d7fd2102e7b3d367f951d571ba7b39a81fb
and from Bsc to Fantom.
https://bscscan.com/tx/0x0540c65acea43657e602fb0c834e1076028a4c3245fc482b4b84c32f70f368dd

Could I get information about missing funds did I do something wrong or is it some kind of bug.

Thank you for future response.

Been waiting for 4 hours stuck on pending

I've been trying to send USDT from polygon to BSC
The transfer transaction is pending. It takes so many hours.
Need your support please.

https://polygonscan.com/tx/0x6848753561c4e0ff6159ba7cf75f619521f4866b47b9f7389d4db63ff15fc74f

Please support SmartBCH network

That would be very useful since there are many swap services but not well connected with other chains

Crosschain transaction from ETH to FTM pending for hours

The deposit transaction of WETH from the ETH network to the Anyswap FTM bridge was successful:
https://etherscan.io/tx/0x16340e5af7168fd3fa43222f9e58b94b361ee48c9129cc7cd0cc5fa191ae31b8

But the transfer transaction is pending and I don't have any information about it. It takes 1,5 hours already.
Other transactions with WETH from Ethereum to Fantom went through meanwhile and they were initiated later.

Could you support me in that matter

How long is FTM Opera -> ETH bridge supposed to take?

How long is 50 FTM Opera -> ETH bridge supposed to take?

Still no FTM ERC20 on my ETH account after 30 min.

Tx here: https://ftmscan.com/tx/0x32a5d414e3a78890beb7a1e5c3c9339c7233cc35a1841445165d4ecfea5d9371

Do I need some ETH on the receiving ETH address to pay for gas fees for the bridge? I did put some, but bridge Tx still stuck. No FTM ERC20 landed on https://etherscan.io/address/0x1f31B7675180fa61b691D0026E1DC557562bB54a

Bridge Transaction not forwarded to Ethereum

Hello together,

one of my transactions to swap anyUSDT from BSC Blockchain to ETH Blockchain seems to be lost / stuck ?

I hope I'm on the correct place here, as not 100% sure about the repo.
I interacted with https://bscscan.com/address/0xb46d67fb63770052a07d5b7c14ed858a8c90f825 and the owner of that contract is https://bscscan.com/address/0x13b432914a996b0a48695df9b2d701eda45ff264 which is listed as AnySwap Deployer.

Expected Behavior:

Send anyUSDT through the frontend hosted on https://multichain.xyz from BSC to ETH. Get a successful transaction on BSC and retrieve the USDT in another transaction on ETH

Actual Behavior:

Send anyUSDT through the frontend hosted on https://multichain.xyz from BSC to ETH. Get a successful transaction on BSC but never retrieve the funds back on ETH

Description:
This is the transaction on BSC: https://bscscan.com/tx/0xdd925f18f00748c874e1939a6c3b784c5ff93a6d203485fcc62b292f428cb835

(Background) I wanted to bridge USDT from ETH to BSC. I used the frontend and send a successful transaction.
Then I realized that I got anyUSDT on the BSC chain and not USDT. As my amount was to big ($36k anyUSDT), there was not enough liquidity, to swap it into any other asset on anyswap.
So I decided to bridge it back to ETH, swap it to DAI and bridge it again, as I have done a lot of time.

The transaction went fine on the BSC Chain and it seems to have called the correct contract code etc.

Function: Swapout(uint256 amount, address bindaddr) ***

MethodID: 0x628d6cba
[0]:  0000000000000000000000000000000000000000000000000000000861c46800
[1]:  000000000000000000000000152b8c153e4f18bfe1cb3f2eaa563813c758e279

However there were no incoming tx on the ETH chain to be found.
As an additional info it might be a problem that the BSC Chain seem to had some problems regarding connectivity. At least as a MetaMask Frontend user, there were some reports to change the endpoint in case you have problems. I hope it's not related to a networt hickup!

Please help me rescue that money back from the chain as it was a substantial amount for me!

Where is the Testnet

How can I see progress of submitted transaction when in testnet?

I spend two days integrating the anycall permissionless bridge. base on your docs
Rinkeby anycall address: 0xf8a363Cf116b6B633faEDF66848ED52895CE703b
Ftm test: anycall address: 0x765277EebeCA2e31912C9946eAe1021199B39C61

A sent my first transaction. Im trying to check status so as stated here..BUT the link is dead. In explorer no testnet! How can I see progress of submitted transaction when in testnet?

This link example provided in the docs is dead as well. In fact several api examples provided in the github docs here don't work anymore. Im wondering if the the permissionless bridge is even ready for production ! There are also many confusing concepts, bridge, router, anycall, anyswap, multichainswap etc. I still don't understand whether i need to use your frontend or build my own. I think a clear developer tutorial from start when when have the token contract, to finish at the point when we test a swap, showing how to integrate the our new tokens should be provided, without assuming the we understand the concept.

Question: How can one access the Multichain Explorer through an API?

This is just a question.. I wanted to do analysis of the most popular flows through the multichain bridge. (Source, Destination, Amount)
But I haven't been able to find an easy way to do this. What would the team recommend or is it possible to access the source that drives the Anyswap explorer view through an API?

How to deploy a complete front-end and cross chain service demonstration？

is there Complete tutorial ？ and where is the bridge contract
