Bridging
Builder Bridges
Section titled “Builder Bridges”The Builder platform provides access to deposit‑only native bridges, as documented in the bridging user guide.
Bridging Legacy Modal
Section titled “Bridging Legacy Modal”Previously, when a user attempted a contract interaction on an L2 with a zero ETH balance, a bridge modal would open. The modal could also be invoked via the query parameter ?bridge=true, e.g., https://nouns.build/explore?bridge=true.
It used native bridge contracts for depositing ETH to Zora / OP / Base and was deposit‑only. Withdrawals were not supported in the modal and must be performed via the respective bridge UIs linked in the user guide. Bridging support remains, but the modal has been deprecated.
