FAQ's

EU contracts are signed with AIO Algorithm Tech EOOD, a licensed VASP in Bulgaria. MiCA authorization is in progress. AIO Technology LLC (Dubai) is the technology services company.

Per-merchant segregated custodial wallets; keys are held in HSM/KMS. AIO does not lend, stake, or proprietary trade client assets.

No. Movements occur only with your explicit authorization. You can configure payout thresholds and optional dual-approval.

2FA/TOTP for all operator accounts (cannot be disabled), IP allow-listing, role-based access, scoped/rotatable API keys, and HMAC-signed callbacks. Dashboard pages show API Key restrictions, callback secret reset, and audit logs/records for callbacks.

Your system creates a pay-in → buyer pays the shown address → AIO validates the on-chain transaction → credits the correct wallet → AIO sends a signed webhook so you can mark the order complete.

One-time pay-ins lock chain/token/amount and require exact payment. Long-term pay-ins return a reusable address with a 90-day lease that auto-renews on each deposit; if there’s no activity for 90 days it becomes Overdue and the address is deactivated until a new deposit or manual close.

Configurable by you; AIO completes the pay-in when your confirmation/threshold is met.

Under/over-payments follow your configured rules. Unsupported tokens are recorded as UnknownSubTransaction and can be admin-bound after review.

Platform fee starts at 0.3% on pay-ins (volume-tiered). Network gas is pass-through.

Your system requests a payout (with chain, token, amount, to_addr) → AIO broadcasts on-chain → monitors confirmations → sends a completion webhook. Approvals follow your threshold/dual-control settings.

0% platform fee; network gas is pass-through. Timing depends on chain conditions and any compliance checks.

USDT settlement only, on any supported chain that has USDT (e.g., EVM chains, TRON, Solana). Deposits in other assets can be converted to USDT on a supported chain per configuration/compliance. (No other stablecoins at this time.)

aio-docs.apifox.cn — includes auth, pay-in/pay-out APIs, pricing endpoints, and callback specs.

Include your API key in the header: Aio-Api-Key: <api-key>. Signatures and encryption are described in Security docs. Create and restrict keys in Dashboard → Integrations → API Management; you can set IP restrictions per key.

• List Transactions GET /v2/tx
• Get Transaction Info GET /v2/tx/info/{txid}
• Create Pay-in POST /v2/tx/pay-in
• Create Long-term Pay-in POST /v2/tx/pay-in-longtime
• Create Payout POST /v2/tx/pay-out
• Price GET /v2/price and Calculate Fiat→Crypto GET /v2/price/calc_vs_price

Configure your URL in Dashboard → Integrations → Callback Management. We send HTTP POST with headers including Algorithm: HMAC-SHA256, Body-MD5, Date, and Aio-Sign (HMAC using your secret). Implement idempotency (e.g., by tx_id/sub_tx_id). AIO retries on failure with exponential backoff (up to 16 attempts). You can reset the secret in the dashboard.

Daily/weekly/all Pay-in/Payout counters, Received/Sent tx counts, Wallet Assets by chain/token, quick Swap/Payin/Payout actions, and a Gas Saved chart.

View All Transactions, Sub Transactions, Pending, and Swap Transactions with filters, amounts/fees, and status (e.g., Pending, Completed, Overdue, Closed). Each entry links to Details.

Create/enable API keys, edit key-level restrictions (e.g., IP allow-listing), rotate/delete keys, and view request logs.

Configure Callback URL, enable/disable, reset callback secret, and review Callback Records with response codes and execution times. Callback response bodies are retained for 30 days in the records view.

TOTP/2FA is enforced and cannot be turned off. Configure IP allow-listing for the organization; only listed IPs are allowed when enabled.

Manage sub-users, roles, status, and 2FA state.

Update operator email and password.
