Smart Contract
A self-executing program deployed on a blockchain that triggers automatically when predefined conditions are met, without requiring an intermediary. Its rules are transparent, auditable, and cannot be unilaterally altered, making it a foundational infrastructure component of decentralized blockchain applications.
Timeline (last 90 days)
Smart contracts carry the risk of code vulnerabilities, which attackers may exploit to move funds, and on-chain transactions are usually irreversible, making losses hard to recover; therefore, whether a project has undergone sufficient auditing and whether its contracts are upgradeable are important references for users assessing risk.
Once a smart contract is deployed to mainnet, its code logic cannot be modified unless the contract has a pre-configured upgrade proxy pattern.
The smart contract reads in advance all rules set by the user (daily quota, per-transaction cap, permitted payment addresses) and makes an approval or rejection decision on each payment request initiated by the agent
If an agent can only send payment requests without holding funds, a compromised agent can at most apply to spend money, and the smart contract can directly reject it
AI agents can make payments in HBAR or USDC, but only within daily limits and per-transaction limits, which are enforced by smart contracts
A smart contract is a self-executing program deployed on a blockchain that automatically triggers when preset conditions are met, requires no intermediary, and cannot be unilaterally altered or stopped
After the contract is deployed, even the Hedera team itself cannot unilaterally bypass the limits set by the user
Atomic settlement relies technically on the atomic execution of smart contracts, where a transaction is only finally committed to the ledger when both the cash token and the securities token simultaneously satisfy the exchange conditions.
Most large-scale cryptocurrency thefts do not stem from private key leaks, but from logical flaws inherent in the smart contract code itself.
Traditional smart contracts (such as those written in Solidity) are deterministic, meaning the same input always produces the same output.
