Definition. The total USD value withdrawn from bridge smart contracts on Ethereum and therefore flowing back into Ethereum and out of the target blockchains, broken out per destination chain.

Technical. Withdrawal volume is computed daily by multiplying the number of tokens withdrawn from bridges by the latest daily price of each token. Bridges are protocols that transfer digital assets from one blockchain to another. When an asset leaves Ethereum, it is deposited and locked into a bridge smart contract, and when it returns to Ethereum it is withdrawn and released. This metric only includes bridge contracts on the Ethereum side, covering deposits into both L1 and L2 blockchains. Each bridge represents a single destination chain, except those labeled multichain, which fan out across multiple chains.
