Tracking DeFi Positions Across Multiple Chains

A spot balance is a number in a wallet. A DeFi position is a claim on a protocol, and the protocol decides what that claim is worth. That difference is why portfolio tools that started as balance checkers tend to under-report serious portfolios by a wide margin.

The four position types that get missed

Only the first column is visible from a naive balance query. The other two require protocol-specific logic, per chain, kept current as protocols upgrade.

Why multi-chain multiplies the problem

Each additional chain adds its own RPC endpoints, its own token lists, its own deployment addresses for the same protocol, and its own reorg behaviour. The work is not additive, it is combinatorial: protocols × chains × versions.

A fund holding the same strategy on Ethereum, Arbitrum and Base is running three different integrations for what it thinks of as one position.

What complete coverage requires

1. Discovery without configuration. The system should find positions from the address alone, not from a list you maintain by hand.
2. Protocol-aware valuation. Unwrap LP and receipt tokens to their underlying assets before pricing.
3. Consistent pricing. One price source, one timestamp, across all chains.
4. Historical reconstruction. Yesterday's position set, re-derivable today.

Point four is the one that gets deferred and then urgently needed at audit time.
