How to use Bitfinex SAT Mode? (Bitcoin units)

Understanding SAT Mode on Bitfinex

1. SAT Mode refers to the display and transaction interface setting where all Bitcoin-related values — including order sizes, balances, and price quotes — are shown in satoshis (sats) rather than BTC.

2. One satoshi equals 0.00000001 BTC, making it the smallest divisible unit of Bitcoin, named after its pseudonymous creator Satoshi Nakamoto.

3. Bitfinex introduced SAT Mode to accommodate precision-focused traders, especially those engaging in micro-trading strategies or executing high-frequency orders where fractional BTC movements matter significantly.

4. The mode does not alter underlying settlement mechanics; all ledger entries and blockchain confirmations still occur in full BTC units — only the UI representation changes.

5. Users must manually toggle SAT Mode via the account settings panel under “Display Preferences”, and the selection persists across sessions unless explicitly changed.

Enabling and Configuring SAT Mode

1. Log into your Bitfinex account using verified credentials and two-factor authentication.

2. Navigate to the top-right user menu and select “Settings”, then click “Trading Preferences”.

3. Locate the “Price & Quantity Display” section and choose “Satoshi (SAT)” from the dropdown for both “Base Currency Display” and “Quote Currency Display”.

4. Save changes — the entire trading interface instantly refreshes, showing order books, open positions, and balance summaries in sats.

5. When placing limit orders, input quantities directly in sats; for example, entering “100000000” corresponds to 1.00000000 BTC.

Trading Mechanics in SAT Mode

1. Order book depth columns reflect bid/ask prices in sats per BTC, meaning a displayed price of “102500000” indicates 1.025 BTC per BTC — effectively a 2.5% premium over parity.

2. Margin calculations remain unchanged in terms of leverage ratio or collateral value but appear scaled: a 10x margin position worth 0.5 BTC displays as 50,000,000 sats of exposure.

3. Funding rate settlements, executed every eight hours, are computed internally in BTC and converted to sats only for display; no rounding occurs during calculation.

4. Deposit and withdrawal addresses function identically — sending 100,000,000 sats to a BTC address is indistinguishable from sending 1 BTC on-chain.

5. API endpoints support SAT Mode through the display_unit parameter; setting it to “sat” returns all numeric fields formatted accordingly, including ticker, order status, and wallet balance responses.

Security and Audit Implications

1. Enabling SAT Mode does not affect private key storage, seed phrase generation, or hardware wallet integration — all cryptographic operations retain standard BTC-level integrity.

2. Transaction history exports include both raw BTC and equivalent sat values in parallel columns, ensuring auditability without unit conversion ambiguity.

3. Bitfinex’s internal reconciliation systems validate every sat-denominated trade against blockchain UTXO outputs, preventing off-ledger drift or display-only discrepancies.

4. Withdrawal confirmation dialogs show final amounts in both formats side-by-side, requiring explicit acknowledgment before broadcast — this dual-format verification reduces misentry risk.

5. No additional KYC documentation or tiered verification is triggered by switching display modes; SAT Mode is purely a frontend configuration option.

Frequently Asked Questions

Q1: Does SAT Mode impact fee calculation?Bitfinex calculates trading fees in BTC and converts them to sats for display; the actual fee amount remains identical regardless of display mode.

Q2: Can I place a market order using SAT Mode?Yes — market orders execute at prevailing order book prices, with size entered in sats; the matching engine resolves execution in native BTC units before settlement.

Q3: Is SAT Mode available on Bitfinex mobile applications?No — as of April 2026, SAT Mode is restricted to the desktop web interface due to UI space constraints and mobile usability considerations.

Q4: Will my API keys behave differently when SAT Mode is active?No — API behavior is unaffected by UI display settings; endpoint responses depend solely on request parameters, not account-level display preferences.
