Definition. The USD value deposited into bridge smart contracts on Ethereum, flowing out of the Ethereum blockchain and into target blockchains, segmented by destination chain. Bridges are protocols that enable digital assets to be transferred from one blockchain to another. When an asset is transferred out of Ethereum, it is deposited and locked into a bridge smart contract. When the asset is transferred back to Ethereum, it is withdrawn and released from the contract.

Technical. Deposit Volume is computed daily by multiplying the number of tokens deposited into bridges by the latest daily price of each token. The metric only includes bridge contracts on the Ethereum side, covering bridge deposits into both L1 and L2 blockchains, providing information on the value transferred to both L1 competitors and L2 scaling solutions. Each bridge represents a single blockchain, except the ones labeled as multichain. That label is used to represent bridges that allow transferring assets across multiple different chains.
