My Skill

Add new chain into the app using the provided intructions.

Instructions

• Add the new case in Blockchain and wire isTestnet, decimals, symbol, chain id, EVM flag, coding/decoding, analytics ids, and wallet assembly.
• Include the chain in Blockchain+AllCases.swift compile guard and list.
• Update derivation/address behavior: DerivationConfigV1/V2/V3, AddressTypesConfig, AddressServiceFactory, and EstimationFeeAddressFactory as needed. For DerivationConfigV1 check docs by links for chain and set specific derivation path if needed.
• Configure RPCs and API keys: TestnetAPINodeInfoProvider, QuickNodeAPIResolver, BlockchainSdkKeysConfig, CommonKeysManager, and BlockchainSdkExample/APIListUtils.
• Add explorer/faucet links via <Chain>ExternalLinkProvider and ExternalLinkProviderFactory.
• Wire network services in WalletNetworkServiceFactory (typically makeEthereumNetworkService for EVM chains).
• Update app features: AccountDerivationPathHelper, ReceiveBottomSheetNotificationInputsFactory, TransactionParamsBuilder, CustomTokenContractAddressConverter, NFTChainConverter, TransactionHistoryProviderFactory, and MoonPayService.
• Update SupportedBlockchains, add only to testable blockchains and testnet blockchains if avilable.
• Add assets and UI mapping: Modules/TangemAssets/Assets/Tokens.xcassets and NetworkImageProvider.
• Add new source files to TangemApp.xcodeproj/project.pbxproj.
• Update/extend tests (e.g. RPC lists or chain mappings) and bump tangem-app-config if chain metadata lives there.
• Finish chain add by building the project and fixing compilation errors if appear.
