    pub s: FixedBytes<32>,
    pub nonce: u64,
    pub implementation: Address,

Holds a signed EIP-7702 authorization for an authority account to delegate to an implementation.

struct SignedDelegation { uint8 v; bytes32 r; bytes32 s; uint64 nonce; address implementation; }

Fields

v: u8

The y-parity of the recovered secp256k1 signature (0 or 1).

r: FixedBytes<32>

First 32 bytes of the signature.

s: FixedBytes<32>

Second 32 bytes of the signature.

nonce: u64

The current nonce of the authority account at signing time. Used to ensure signature can’t be replayed after account nonce changes.
