Bridge research - Githubissues

jahabeebs commented 7 months ago

Description

I've researched around 20 bridges and narrowed it down to a few options:

1) Squid router (this is my favorite option currently)

Built on axelar, good security
Good front-end resources and SDK is easy to use (widget docs here: https://docs.widget.squidrouter.com/ and here: https://github.com/0xsquid/widget-integrations, and here: https://docs.squidrouter.com/choose-how-to-integrate)
37+ chains supported, used by 50+ co's like ledger, pancakeswap

Unknowns:

Seems no sepolia support yet
Would need to contract them about supporting tokens we want to add (they support many like wsteth here: https://v2.app.squidrouter.com/)
Can request supporting token allowlisting here: https://form.typeform.com/to/wVLxNgSd https://docs.squidrouter.com/

Unknowns:

Arbitrum and mainnet support on 11/30
Not sure if this protocol requires smart contract changes for compatibility? Might need to contact https://docs.wormhole.com/wormhole/quick-start/cross-chain-dev

60+ chains, 16k tokens supported, 60+ dexs supported
Great front-end resources: Widget (https://tools.rubic.exchange/widget) and SDK (https://tools.rubic.exchange/sdk)
Customizable fees and RPCs

Unknowns:

Not convinced about security, certik audit + some others I don't recognize (https://docs.rubic.finance/rubic/security)
130+ projects using it but don't recognize these projects
Didn't see sepolia support mentioned
Need to request token support (https://docs.rubic.finance/integrate-widget/listing)

@pi0neerpat Here's a summary of my bridge research. Do you have any preference between these?

Squid router Can bridge wsteth from mainnet to arbitrum: yes Exchange rate: 1 wstETH=0.9990wstETH Without fees: yes, there are no fees currently (https://docs.squidrouter.com/architecture/transaction-times-and-fees) Pre-select/limit assets: unclear, can select which assets appear on load and pin favorites but not sure if it means you can completely get rid of others (https://docs.squidrouter.com/widgets/widget/customization-guide)
Wormhole protocol: Can bridge wsteth from mainnet to arbitrum: supposedly support was supposed to be rolled out today (11/30) but have to confirm that this is possible now. wsteth is supported mainnet <> cosmos (example bridge using wormhole: https://bridge.neutron.org/bridge) Exchange rate: unclear since support rolled out today and haven't found UI with this option Without fees: currently 0 (https://docs.wormhole.com/wormhole/explore-wormhole/gateway#fees-required) Pre-select/limit assets: yes (https://docs.wormhole.com/wormhole/quick-start/wh-connect)
Rubic finance: Can bridge wsteth from mainnet to arbitrum: Yes Exchange rate: 1 wstETH = 1.005 wstETH Without fees: No, 0.00102635 ETH on a 1 wstETH swap from mainnet to arbitrum. this is roughly $2 though the network notes that the exchange fee on the platform is $1 for every transaction (see here: https://rubic.exchange/swap/eth/usdt) Pre-select/limit assets: pre-select yes, but unclear if you can provide multiple tokens and limit it to only those (https://github.com/Cryptorubic/rubic-widget)

Closing this initial round of review.

@pi0neerpat @jahabeebs consider the official arbitrum bridge.

mainnet -> arb instant, takes a longer delay in the reverse
its direct token to token, no slippage or fees. why make our customers pay more in fees?
only thing, you must have a tiny bit of gas on arbitrum when bridging tokens there: https://support.arbitrum.io/hc/en-gb/articles/18213854684699
