Interface GCREditNonce

Nonce-increment GCR edit. amount is a counter delta, not a token amount — always 1 in current code. Kept as number because the fork does not change its encoding. Do not confuse with GCREditBalance.amount.

interface GCREditNonce {
    account: string;
    amount: number;
    isRollback: boolean;
    operation: "add" | "remove";
    txhash: string;
    type: "nonce";
}
