`authority`	`Signer`	The authorized signer of the credential
`credential`	`PublicKey \| Pda`	The credential account associated with the schema
`schema`	`PublicKey \| Pda`	The schema account that defines the attestation structure
`attestation`	`PublicKey \| Pda`	The attestation account to create
`systemProgram`	`PublicKey \| Pda`	The System Program account (defaults to '11111111111111111111111111111111')
`nonce`	`Address`	A unique identifier for the attestation
`data`	`ReadonlyUint8Array`	The attestation data that must conform to the schema
`expiry`	`number \| bigint`	The expiration timestamp for the attestation

Example

import { getCreateAttestationInstruction } from "sas-lib";

const transaction = getCreateAttestationInstruction({
    payer: payerSigner,
    authority: authoritySigner,
    credential: credentialPublicKey,
    schema: schemaPublicKey,
    attestation: attestationPublicKey,
    systemProgram: systemProgramPublicKey,
    nonce: noncePublicKey,
    data: attestationData,
    expiry: expiryTimestamp
});

// Send the transaction
await transaction.sendAndConfirm();

Important Notes

Only authorized signers of the credential can create attestations
The authority must be a signer of the transaction
The payer must be a signer of the transaction
The attestation account must be writable
The credential and schema accounts must be readable
This operation requires the System Program for rent exemption calculations
The schema must not be paused
The data must conform to the schema's structure and validation rules
The nonce must be unique for each attestation
The expiry timestamp must be in the future
The attestation will be invalid after the expiry timestamp
The credential must be associated with the schema
