With the launch of Aptos, Sui, numerous Layer 2s, and even talk of Layer 3s on the horizon, it is clear that the future will be multi-chain. But for these chains to sustainably co-exist, we must have reliable ways of bridging across them. Bridges remain one of the main vectors for attack within decentralised networks, because transmitting information across blockchains involves relaying messages off-chain, which introduces elements of centralisation and exposes the system to exploits. In the ...
