feat: add dynamic ERC20 token discovery via Alchemy API#7
Merged
Conversation
Adds discoverTokens() to EvmChainAdapter using alchemy_getTokenBalances for automatic ERC20 enumeration across Ethereum, Polygon, Arbitrum, Optimism, and Base. Includes TokenDiscoveryService for multi-chain aggregation. Reports per-token error details instead of silently skipping failures. Filters spam tokens. 18 new tests (TDD).
