## What it is
A collection of community-contributed TVL (Total Value Locked) adapters for DefiLlama, written in JavaScript, that compute on-chain protocol TVL from blockchain data. It includes tooling for testing adapters and an agent skill for AI-assisted adapter authoring.

## Use cases
- list a defi protocol's TVL on DefiLlama
- compute total value locked for a smart contract protocol
- write and test a TVL adapter for a new blockchain project
- track historical TVL of a protocol at a past timestamp
- query on-chain balances across multiple chains for a protocol

## When to choose
- you want your DeFi protocol listed on DefiLlama's TVL rankings
- you need a standardized pattern for computing protocol TVL from chain data
- you're contributing TVL data (not volume/fees/revenue) to DefiLlama

## When to avoid
- you need adapters for volume, fees, revenue, or other non-TVL metrics (use dimension-adapters instead)
- you need a general-purpose blockchain analytics library rather than DefiLlama-specific adapters
- you want to add custom npm dependencies, which the repo disallows
