This is how infrastructure get's built and changes the system đ„
Curve FastBridge.
An idea theorised almost a year and change ago. Now brought to life by Roman (curve core dev) with a significantly simplified design: just use LayerZero + donât fuss too much about L2<>L2 transfers (yet?).
The gist is simple: we donât like so many versions of the same token so consider the L2 main bridge minted token as canonical, use a message passing infra to notify layer-1 vault that a deposit occurred, and transfer âunbackedâ token (debt) from layer-1 vault to use.
The token that the user bridged back to L1 (that is stuck in the challenge period) âbacksâ the L1 debt that was transferred to the user.
This works only for stablecoins that you can mint unbacked, and does quite good things for L2 âpegâ.
Bridge can be changed by LZ does a pretty good job. If tether likes it, so do we.
