# DefiLlama TVL

Any project that has implemented a functioning [DefiLlama adapter](https://github.com/DefiLlama/DefiLlama-Adapters/tree/main/projects) can configure KPI options to track its TVL measured in USD. In addition to [common ancillary data parameters](https://docs.outcome.finance/kpi-options/kpi-option-configuration/common-ancillary-data-parameters) the deployer should configure DefiLlama TVL specific settings as documented below. Full specification of DefiLlama TVL data source is available in its [implementation document](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/defillama-tvl.md) to be referenced by verifiers.

### Endpoint

`Endpoint` string value should be set to project's DefiLlama TVL API endpoint in the format `"https://api.llama.fi/protocol/<PROJECT_SLUG>"` where `<PROJECT_SLUG>` should be replaced with project slug name used in DefiLlama TVL adapter.

### Metric Selector

In order to instruct verifiers on the location of TVL value within returned `Endpoint` response `Key` string parameter should be set to `tvl[i].totalLiquidityUSD where tvl[i].date is the latest daily timestamp before the evaluated timestamp`.

By default TVL across all chains would be tracked. If however the KPI metric was to track TVL on a particular chain additional optional `ChainName` string parameter should be set to the selected chain name. Names of supported chains can be observed as key names under the returned `chainTvls` object when querying the `Endpoint`.
