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\":\"paris\",\"libraries\":{},\"metadata\":{\"bytecodeHash\":\"ipfs\"},\"optimizer\":{\"details\":{\"constantOptimizer\":true,\"cse\":true,\"deduplicate\":true,\"inliner\":true,\"jumpdestRemover\":true,\"orderLiterals\":true,\"peephole\":true,\"simpleCounterForLoopUncheckedIncrement\":true,\"yul\":true,\"yulDetails\":{\"optimizerSteps\":\"dhfoD[xarrscLMcCTU]uljmul:fDnTOcmu\",\"stackAllocation\":true}},\"runs\":999999999},\"remappings\":[\":@openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/\",\":@uniswap/v3-core/=lib_uniswap/v3-core/\",\":@uniswap/v3-periphery/=lib_uniswap/v3-periphery/\",\":ds-test/=lib/forge-std/lib/ds-test/src/\",\":forge-std/=lib/forge-std/src/\",\":openzeppelin-contracts/=lib/openzeppelin-contracts/\",\":v3-core/=lib_uniswap/v3-core/\",\":v3-periphery/libraries/=lib_uniswap/v3-periphery/contracts/libraries/\"]},\"sources\":{\"lib/forge-std/src/StdChains.sol\":{\"keccak256\":\"0x51e6eb138fc953fac1ac78012a39b3f16d9289ce06a222ba93bb0621768f96e6\",\"license\":\"MIT\",\"urls\":[\"bzz-raw://653c577e054cf578594148a07b286571d494f401b6d4a940d3ccabd47b29233d\",\"dweb:/ipfs/QmTWDVvR4m82MGXWYY8BCaVN89TguQJSLqRgzHzrMkFHtx\"]},\"lib/forge-std/src/Vm.sol\":{\"keccak256\":\"0xb569d0b4398fad95f508fb854e832143edf69a897af4250f5f60fe195a2066c5\",\"license\":\"MIT\",\"urls\":[\"bzz-raw://84b722ada97ea7bb841cdc0fa556aa36a02ff2d380fa24f6dc0717a71c6d9c7c\",\"dweb:/ipfs/QmfCH9Q4tvJhPM286GFsE4UCP4YncLpRu4Nwa2ZkHdRfbw\"]}},\"version\":1}",

provides information about EVM compatible chains that can be used in scripts/tests.\n For each chain, the chain's name, chain ID, and a default RPC URL are provided. Chains are\n identified by their alias, which is the same as the alias in the `[rpc_endpoints]` section of\n the `foundry.toml` file. For best UX, ensure the alias in the `foundry.toml` file match the\n alias used in this contract, which can be found as the first argument to the\n `setChainWithDefaultRpcUrl` call in the `initializeStdChains` function.\n There are two main ways to use this contract:\n 1. Set a chain with `setChain(string memory chainAlias, ChainData memory chain)` or\n `setChain(string memory chainAlias, Chain memory chain)`\n 2. Get a chain with `getChain(string memory chainAlias)` or `getChain(uint256 chainId)`.\n The first time either of those are used, chains are initialized with the default set of RPC URLs.\n This is done in `initializeStdChains`, which uses `setChainWithDefaultRpcUrl`. Defaults are recorded in\n `defaultRpcUrls`.\n The `setChain` function is straightforward, and it simply saves off the given chain data.\n The `getChain` methods use `getChainWithUpdatedRpcUrl` to return a chain. For example, let's say\n we want to retrieve the RPC URL for `mainnet`:\n - If you have specified data with `setChain`, it will return that.\n - If you have configured a mainnet RPC URL in `foundry.toml`, it will return the URL, provided it\n is valid (e.g. a URL is specified, or an environment variable is given and exists).\n - If neither of the above conditions is met, the default data is returned.\n Summarizing the above, the prioritization hierarchy is `setChain` -> `foundry.toml` -> environment variable -> defaults." }, "fullyImplemented": true, "linearizedBaseContracts": [ 4516 ], "name": "StdChains", "nameLocation": "1917:9:4", "scope": 4517, "usedErrors": [], "usedEvents": [] } ], "license": "MIT" }, "id": 4 }
