Definition. The TVL dominance of each target-blockchain bridge, expressed as that bridge's TVL divided by the total TVL across all bridges.

Technical. Per-bridge TVL is computed daily by multiplying the number of tokens locked in each bridge smart contract by the latest daily price for each token, then divided by the total TVL across all bridges. 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asset leaves Ethereum, it is deposited and locked into a bridge smart contract, and when it returns to Ethereum it is withdrawn and released.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.

Interpretation. A rising relative TVL means the target blockchain is gaining USD-denominated dominance inside the bridge economy, and a falling one means it is losing it.
