import { Authorization } from 'ox'
Examples
An Authorization can be instantiated from an EIP-7702 Authorization tuple in object format.
import { Authorization } from 'ox'
const authorization = Authorization.from({
address: '0x1234567890abcdef1234567890abcdef12345678',
chainId: 1,

})

A Signature.Signature

.
import { Authorization, Secp256k1 } from 'ox'
const authorization = Authorization.from({
address: '0xbe95c3f554e9fc85ec51be69a3d807a0d55bcf2c',
chainId: 1,
nonce: 40n,
})
const signature = Secp256k1.sign({
payload: Authorization.getSignPayload(authorization),
privateKey: '0x...',
})
const authorization_signed = Authorization.from(authorization, { signature })
