Viem Version

>2.35.1

Current Behavior

When trying to use readContract, i got this typescript error:

Property 'authorizationList' is missing in type '{ abi: readonly [{ readonly type: "function"; readonly name: "totalSupply"; readonly inputs: readonly []; readonly outputs: readonly []; readonly stateMutability: "nonpayable"; }, ... 152 more ..., { ...; }]; address: 0x${string}; functionName: "totalSupply"; blockNumber: bigint; }' but required in type '{ account?: 0x${string} | Account; authorizationList: any; blockNumber?: bigint; blockTag?: BlockTag; factory?: 0x${string}; factoryData?: 0x${string}; stateOverride?: StateOverride; }'

Seems the issue come from here:

export type TransactionRequest<quantity = bigint, index = number> = OneOf<
  | TransactionRequestLegacy<quantity, index>
  | TransactionRequestEIP2930<quantity, index>
  | TransactionRequestEIP1559<quantity, index>
  | TransactionRequestEIP4844<quantity, index>
  | TransactionRequestEIP7702<quantity, index>
>

Where all transactions type except TransactionRequestEIP7702 have an optional authorizationList property, but required for EIP7702.

It's working fine in version <= 2.35.0.

Expected Behavior

It should narrow the correct transaction type when not using any EIP7702 transaction

@jxom Yes, in our codebase we cannot enable strict, and Viem was working fine prior to 2.35.1 without strict enabled.
So either it's a breaking change and doing this in a patch was not the best idea because of how node dependencies works, or it's not a breaking change and it should be fixed to work without strict enabled.

Viem is designed for strict mode in TS. See the TypeScript section on the Viem docs.
