Research: Seamless Bridging

[dOrgJelli]

Research bridging to see how seamless we can make it for a user to mutli-send to multiple networks.

For example, 100 USDC on Polygon being sent to multiple recipients on:

• polygon
• mainnet
• optimism

Options

• Synapse protocol
• Wormhole
• Stargate
• Li.fi
• Across
• Rhino.fi

Chains

• Synapse protocol: https://docs.synapseprotocol.com/synapse-bridge/contract-addresses
• Wormhole: https://docs.wormhole.com/wormhole/blockchain-environments/evm
• Stargate: https://stargateprotocol.gitbook.io/stargate/multisigs
• Li.fi: https://docs.li.fi/smart-contracts/deployments
• Across: https://docs.across.to/v/developer-docs/developers/contract-addresses - missing (but has zksync)
• Rhino.fi: https://tech.rhino.fi/rhino.fi/the-details/contracts - missing a couple

Simplest to use

• Synapse protocol
• Stargate
• Li.fi

Can use directly in Solidity

• Stargate

Potential route forward

• Use gnosis safe or simple multicall contract with ownership to call the stargate bridge (e.g. https://ethereum.stackexchange.com/questions/148040/multicall-and-transferfrom)
