Goal of the proposal

This proposal sets 1) the UDT address and 2) the Swap Burner contract address in the main Unlock factory contract on the following chains: Arbitrum,Base,Optimism.

About this proposal

Now that UDT has been bridged to Arbitrum, Base and Optimism, the new address has to be set in the main Unlock contract for the tokens to be distributed or swap/burned. For that, we call the configUnlock function with the bridge UDT address as parameter (keeping other parameters untouched).

A SwapBurner helper contract has been deployed on all three chains and will be added as setting to the main Unlock contract. This will enable the “swap and burn” feature of fees collected by the protocol on these chains, following the deployment of bridged versions of UDT there.

How it works

The proposal uses a cross-chain proposal pattern that, once passed, will send the calls to multiple chains at once. This pattern has been introduced and tested in a previous proposal.
