I want to create a local bridge for a specific token between BSC and Tron Chain
What are the best routes to take in achieving this please?

@karola96

if you want to create a centralized bridge, it all comes down to a script sending a transaction on another chain initialized by a transaction on another chain

What about an oracle?
Will that be an overkill?

the script can be the oracle itself

Hm. Okay
Thanks

a basic bridge can be built by doing
1) the contract to handle the core logic and emit events
2) a listener script or scripts that listen for events and wait for confirmation blocks to avoid reorgs
3) a script that handle the action to do on the other chain
of course before using it on mainnet with real assets it's better to audit all the files involved.
If the contract is audited and safe but the script has a sort of bad logic, it can be exploited.
Same opposite, you can audit the bridge but not the contract and then get exploited there

decentralized bridges instead are far too complex (as they require strong and in-depth security) and not in my interests for now so i can't help on those

It's really hard to understand how those works tbh

Thanks for this
You've given me my guideline

the best decentralized oracle service is Chainlink, i doubt anything will ever beat their tech

so you want to study chainLink if that's your interest

also look up for centralized bridges hacks so you understand some risks involved in bridging in general (like nonce/signature reuse, transfers based on LP amount, etc)

Still trying to wrap my head around Aave 😅
Adding Chainlink this early will make my head explode

This is a bridge between BSC and Tron Chain
Tron Chain isn't EVM compatible so I don't think I should worry about nonce/signature reuse?

Thank you 🙏

Absolutely, Chainlink has truly set a high standard in the realm of decentralized oracle services!

Ohhhhh 🤔 no idea. never developed on Tron, yet

Hope more devs can join them so they can decrease the overall prices and make it more used everywhere.
Fractionalizing the market with more similar tools (at that complexity) is kinda waste of magic imho

Hi Krakovia
In building the script for my bridge to Tron Chain, I discovered that the sdk doesn't have an event listener
How else do you think I can circumvent that?

which sdk?

event listener would make sense only with websocket

so if you are refering to contrat events, just use a websocket rpc

tronweb

Not sure I understand but I'll research with this wildcard at hand. Thanks

Okay, so I'll have to do the heavy lifting then right?

The chain is so impregnable

what do you mean

There's no wss RPC I can use

On the chain

https://www.ankr.com/rpc/tron/

Thank you

I see only rest API and JSON RPC

check better

brother

go down

I'll have to upgrade it seems

yes

it is not expensive

btw seems that tron has watch() method

@Steffqing check this too
https://tronprotocol.github.io/documentation-en/architecture/event/

I don't know any Java 😑

you should read everything first🥲

https://tronprotocol.github.io/documentation-en/architecture/event/#prepare-event-subscription-script

btw
go on with ankr

easiest choice

or check this

I got lost here
sock.connect("tcp://127.0.0.1:5555")

Is that tcp address meant to be the wss url?

Tronweb you mean?
Let me check it ASAP
