feat: add `signEip7702Authorization` to `KeyringController` #5301

jeffsmale90 · 2025-02-07T03:05:26Z

EIP-7702 defines a new struct Authorization which represents authority to set a pointer to a contract address at an EOA - effectively making the EOA perform as a smart contract.

This change integrates the new signEip7702Authorization method added to eth- simple and hd keyrings in MetaMask/accounts#182. This is exposed via KeyringController.signEip7702Authorization as well as the message handler KeyringController:SignEip7702Authorization.

See https://github.com/ethereum/EIPs/blob/master/EIPS/eip-7702.md for details

Could you update the changelog for the keying controller package? Certainly the keyring version bumps would be breaking changes at least. I don't see changes documented right now in either the PR description or the changelog file - we do require them to be listed in one place or the other, so that we know how to release this.

packages/keyring-controller/src/KeyringController.ts

+
+    return await keyring.signEip7702Authorization(from, [
+      chainId,
+      contractAddress as Hex,


Nit: This cast is suppressing a TypeScript error about the undefined case. We asserted just a couple lines above that this value can be undefined. Could you clarify why we're overriding that error here? Is the address expected to be undefined in some cases or not?

Edit: I think I see what happened now, suggestion on this here: https://github.com/MetaMask/core/pull/5301/files#r1958425721

Gudahtt · 2025-02-17T15:31:16Z

packages/keyring-controller/src/KeyringController.ts

+    const contractAddress = ethNormalize(params.contractAddress) as
+      | Hex
+      | undefined;
+
+    return await keyring.signEip7702Authorization(from, [
+      chainId,
+      contractAddress as Hex,


Nit: Perhaps this is what you meant to do:

Suggested change

const contractAddress = ethNormalize(params.contractAddress) as

| Hex

| undefined;

return await keyring.signEip7702Authorization(from, [

chainId,

contractAddress as Hex,

const contractAddress = ethNormalize(params.contractAddress) as Hex;

return await keyring.signEip7702Authorization(from, [

chainId,

contractAddress,

Ideally we'd validate the response from ethNormalize is non-falsy as well, or use a normalization function that returns Hex rather than string | undefined. But I see we make this assumption elsewhere already, so we can leave this improvement for a future PR.

…s provided (#5353) #5301 introduced a new method for signing EIP-7702 Authorizations. This change adds validation to ensure that `contractAddress` is specified, rather than type asserting the `contractAddress` to `Hex`.
