# Security Guarantees

> What security guarantees does the protocol provide

### Non-Custodial Execution

User funds are never held by solvers or third parties. They remain locked within the protocol until execution is verified.

### Solver Capital Protection

Once funds are escrowed and a solver is selected, repayment capital is reserved and cannot be withdrawn or reassigned.

### Replay Protection

Each intent is uniquely identified and can only be settled once. This prevents double claims or repeated fulfillment proofs.

### Deterministic Settlement

The outcome of each intent is determined by on-chain state transitions rather than off-chain trust assumptions.
