Smart contract risk
Bugs inPlanRegistry, LoanGuard, or the protocols they call (PancakeSwap, Venus, issuer token contracts) could lose funds.
Mitigations: OpenZeppelin base contracts; per-run caps; no funds held between calls; fuzz tests (5,000 runs) and internal adversarial reviews; source verified on BscScan. Portir has not had an external audit. See Audits.
Issuer and asset risk
A stock token is a claim through its issuer (Ondo, bStocks, xStocks), under that issuer’s terms. Issuers can halt a token (dividends, splits, earnings), change multipliers, or restrict holders. Mitigations: halted tokens are always BLOCK; per-share prices account for multipliers; Portir shows which issuer it picked and why.Price and liquidity risk
On-chain prices drift when the US market is closed, and pools can be thin. Mitigations: the Guard blocks premiums above 1%; swaps revert below a 0.5% minimum output (1% slippage on the agent’s mainnet path); smart timing waits for the open.Oracle and data risk
The Guard depends on the Binance RWA Data API for sessions and reference prices. Missing or wrong data could lead to wrong verdicts. Mitigations: a missing exchange price is BLOCK, never guessed; stale-looking issuers (deep discounts) are ranked last.Liquidation risk (loans)
Collateral can fall faster than the agent can react, the buffer can run out, or the cap can be too small. Mitigations: rescue every 5 minutes past your trigger; the target and cap are yours to set. Loan Guard cannot add collateral and does not guarantee you will not be liquidated.Agent and operator risk
The hosted agent can go offline, its model provider can fail, or its keys can leak. Mitigations: plans keep their schedule on-chain and resume when the agent returns; the executor’s power is capped by the contracts; you can name yourself or your own agent as executor; the news check fails open.Counterparty and access risk
Binance APIs can refuse requests (for example40304 from cloud IPs) or be unreachable in some regions.
Mitigations: server-side reads; testnet mode for trying everything; non-custodial design, so your assets stay in your wallet whatever happens to Portir.
