For each chain, the chain's name, chain ID, and a default RPC URL are provided. Chains are identified by their alias, which is the same as the alias in the `[rpc_endpoints]` section of the `foundry.toml` file. For best UX, ensure the alias in the `foundry.toml` file match the alias used in this contract, which can be found as the first argument to the `setChainWithDefaultRpcUrl` call in the `initializeStdChains` function. There are two main ways to use this contract:   1. Set a chain with `setChain(string memory chainAlias, ChainData memory chain)` or      `setChain(string memory chainAlias, Chain memory chain)`   2. Get a chain with `getChain(string memory chainAlias)` or `getChain(uint256 chainId)`. The first time either of those are used, chains are initialized with the default set of RPC URLs. This is done in `initializeStdChains`, which uses `setChainWithDefaultRpcUrl`. Defaults are recorded in `defaultRpcUrls`. The `setChain` function is straightforward, and it simply saves off the given chain data. The `getChain` methods use `getChainWithUpdatedRpcUrl` to return a chain. For example, let's say we want to retrieve the RPC URL for `mainnet`:   - If you have specified data with `setChain`, it will return that.   - If you have configured a mainnet RPC URL in `foundry.toml`, it will return the URL, provided it     is valid (e.g. a URL is specified, or an environment variable is given and exists).   - If neither of the above conditions is met, the default data is returned. Summarizing the above, the prioritization hierarchy is `setChain` -> `foundry.toml` -> environment variable -> defaults.\",\"version\":1}},\"settings\":{\"compilationTarget\":{\"lib/forge-std/src/StdChains.sol\":\"StdChains\"},\"evmVersion\":\"cancun\",\"libraries\":{},\"metadata\":{\"bytecodeHash\":\"ipfs\"},\"optimizer\":{\"enabled\":true,\"runs\":200},\"remappings\":[\":@openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/\",\":balancer-v2/interfaces/=lib/balancer-v2-monorepo/pkg/interfaces/contracts/\",\":ds-test/=lib/openzeppelin-contracts/lib/forge-std/lib/ds-test/src/\",\":erc4626-tests/=lib/openzeppelin-contracts/lib/erc4626-tests/\",\":forge-std/=lib/forge-std/src/\",\":openzeppelin-contracts/=lib/openzeppelin-contracts/\"],\"viaIR\":true},\"sources\":{\"lib/forge-std/src/StdChains.sol\":{\"keccak256\":\"0x9cc29c28f49d0b7f7b2f1aa32d8273f8a087bf62eb3fb22d893df824052c25ef\",\"license\":\"MIT\",\"urls\":[\"bzz-raw://42dcb36cb10b878a0d5b20ce3a4a3ba4f51f44d7731a66ac1133c699bc80b31b\",\"dweb:/ipfs/QmY6q7SaHQMLBb3rS6xZdArPaXoskWeqF6oJwUeZ3gKLZj\"]},\"lib/forge-std/src/Vm.sol\":{\"keccak256\":\"0x51fec240abc6dd23e0ee6de7c65106379aef732cad6c4ae5df6b55db886e7456\",\"license\":\"MIT OR Apache-2.0\",\"urls\":[\"bzz-raw://a47d9c0a9876e7f9e411843b994a741d4ac1a87d8459ffc3c56359de691ddc1a\",\"dweb:/ipfs/QmQiFN9b3Y2azrD1RBfAKEuAG3YeJkMzA2DGzgEE9kMeEK\"]}},\"version\":1}","metadata":{"compiler":{"version":"0.8.27+commit.40a35a09"},"language":"Solidity","output":{"abi":[],"devdoc":{"kind":"dev","methods":{},"version":1},"userdoc":{"kind":"user","methods":{},"version":1}},"settings":{"remappings":["@openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/","balancer-v2/interfaces/=lib/balancer-v2-monorepo/pkg/interfaces/contracts/","ds-test/=lib/openzeppelin-contracts/lib/forge-std/lib/ds-test/src/","erc4626-tests/=lib/openzeppelin-contracts/lib/erc4626-tests/","forge-std/=lib/forge-std/src/","openzeppelin-contracts/=lib/openzeppelin-contracts/"],"optimizer":{"enabled":true,"runs":200},"metadata":{"bytecodeHash":"ipfs"},"compilationTarget":{"lib/forge-std/src/StdChains.sol":"StdChains"},"evmVersion":"cancun","libraries":{},"viaIR":true},"sources":{"lib/forge-std/src/StdChains.sol":{"keccak256":"0x9cc29c28f49d0b7f7b2f1aa32d8273f8a087bf62eb3fb22d893df824052c25ef","urls":["bzz-raw://42dcb36cb10b878a0d5b20ce3a4a3ba4f51f44d7731a66ac1133c699bc80b31b","dweb:/ipfs/QmY6q7SaHQMLBb3rS6xZdArPaXoskWeqF6oJwUeZ3gKLZj"],"license":"MIT"},"lib/forge-std/src/Vm.sol":{"keccak256":"0x51fec240abc6dd23e0ee6de7c65106379aef732cad6c4ae5df6b55db886e7456","urls":["bzz-raw://a47d9c0a9876e7f9e411843b994a741d4ac1a87d8459ffc3c56359de691ddc1a","dweb:/ipfs/QmQiFN9b3Y2azrD1RBfAKEuAG3YeJkMzA2DGzgEE9kMeEK"],"license":"MIT OR Apache-2.0"}},"version":1},"id":2}
