Sidechain
Protocol
Independent chain bridged to a main chain for transfers.
A sidechain is a separate chain that runs beside a main chain and connects via bridges. It uses its own validators and rules, which adds different trust assumptions than an L2.

Bridge risk and different validator security. Use official bridges and review documentation.Can I use the same wallet?
