Cross-chain bridges are always difficult to build. LayerZero and Axelar have built part of it, while Lagrange suggests using proofs to pave the bridge deck, without using relayers as bridge piers. The bridge is fast, but if the current is strong, will the deck wobble? A transaction crosses over; do the ledgers on both sides match up? This bridge has just been built, and not many dare to walk on it; everyone is watching from the shore.
