Environment variables

Most settings can be overridden per chain via environment variables. The chain name is uppercased and used as a prefix, e.g. ETHEREUM_RPC, BSC_RPC_MULTICALL_V3. Every key is also resolved with an SDK_ or LLAMA_SDK_ prefix (checked in the order LLAMA_SDK_<KEY> → SDK_<KEY> → <KEY>), so SDK_ETHEREUM_RPC works too.

| Variable | Description | | --- | --- | | <CHAIN>_RPC | RPC URL(s) for the chain (comma-separated for multiple). | | <CHAIN>_RPC_MULTICALL_V3 | Address of a Multicall3 contract for the chain. Setting it enables the Multicall3 code path for that chain (even if the chain is not in the built-in registry) and uses this address. Takes precedence over the built-in registry and the deployment-block gating. | | <CHAIN>_RPC_MULTICALL | Address of a legacy (v2) multicall contract, used only when Multicall3 is not available for the chain. | | <CHAIN>_MULTICALL_CHUNK_SIZE | Max number of calls per multicall batch for the chain. |

Chain RPC PR

Before putting up a PR for new chain, check if we already support it here: https://unpkg.com/@defillama/sdk@latest/build/providers.json

Everytime we publish a new sdk version, we automically pull latest list from chainlist.org and include it.
