Cross-chain bridge-usage report for an EVM wallet with exposure tier API

Bridge-usage analytics for an EVM wallet: over a bounded window of Blockscout ERC-20 token-transfers plus native transactions, it matches every counterparty against a curated cross-chain bridge label set (Wormhole, Synapse, Polygon, Optimism, Base, Avalanche, Multichain and more), detects exactly which bridges the wallet has used, splits inflow vs outflow USD per bridge, totals bridged volume, counts the number of distinct bridges, picks the dominant route, derives an inbound/outbound/balanced direction bias, and folds it into a four-level bridge-exposure tier (none | light | moderate | heavy) with a 0-100 exposure score and a plain-English summary — heavy multi-bridge usage is a cross-chain-movement / fund-obfuscation signal. Answers 'Which bridges has this wallet used?', 'How much value did this wallet move across chains?', 'Is this wallet bridging funds out (exit/obfuscation)?', 'How cross-chain-active is this address?'.
